We supply 12 mm porcelain full slabs. This guide covers performance, kitchens, bathrooms, outdoors, fabrication, and what to confirm before you buy. 12 mm Porcelain Slabs: Benefits, Applications & Fabrication We are Verona Quartz Surfaces, a family owned wholesale supplier of full slabs in Sun Valley, California. We supply full slabs only. We do not fabricate, cut, template, or install. Cutting, edging, and installation belong to independent qualified fabricators and installers that you select, and much of this guide is devoted to helping you choose them well and hold them to a clear written scope. This guide is written for homeowners, designers, architects, contractors, fabricators, dealers, and other technical buyers. It explains what our 12 mm porcelain slabs offer, where they work, what the testing behind them actually says, and what must be confirmed before fabrication and installation. It is not an installation manual: your fabricator and installer own the assembly decisions for your project, and this guide names those decisions and the answers to require. For choosing designs, visiting the showroom, and comparing fabricator quotes, our See the Full Slab: Selection & Purchasing Guide carries that journey. For site readiness and installation-day sequencing, our Installation Readiness Guide covers it in full. We link to those guides rather than repeat them here. On This Page 1.

What Your Fabricator Does 8. Fiberglass Mesh Backing 9. Safe Fabrication and Dust 10. Who Is Responsible for What 11. Qualify Your Fabricator and Installer Download the 12 mm Porcelain Slabs Guide (PDF) One Material for the Whole Home What a 12 mm full slab is, and how to plan a project around it. A Full Slab, Not a Tile A full slab is a single panel 126 inches by 64 inches (56.00 square feet) — roughly ten and a half feet by five feet four inches — at 12 mm thick, carrying a fiberglass mesh backing, and rated for interior and exterior surfaces. That size is the reason porcelain can do what smaller formats cannot: fewer seams, longer runs, and designs that flow across a wall or a countertop without interruption. We offer 89 porcelain designs. Finishes vary by design; across the line they include polished, natural, honed, leather, silk, matte, carved, hammered, soft, and three-dimensional carved and natural textures, in single finishes and combinations. No design carries every finish, so confirm the finishes available for the design you want before you commit to it. All of our designs are available book-matched, so two panels mirror each other at a seam like an open book, turning the joint into a feature instead of a flaw. If book-matching matters to you, say so early and see the slabs in person, including outside the showroom where daylight shows the design honestly. Plan the Rooms Together One material can cover your kitchen countertop, your bathroom floor, your shower wall, and your patio — in the same design, from the same slab. That continuity is the central planning advantage of 12 mm porcelain. The finish changes the look and the feel underfoot and underhand, so see and touch large samples rather than judging from a small chip. If a floor will be walked on when wet, specify a textured finish and confirm slip suitability for that finish with your installer; the finish decision belongs with the room decision, not after it. Why 12 mm Earns Its Place Thick enough for countertops, lighter than 20 mm, versatile across rooms — with the limits stated. A Balance, Not a Minimum Twelve millimeters balances material thickness, manageable weight, large-format versatility, and fabrication possibilities. It is not a minimum threshold below which porcelain stops being useful, and this guide does not present it as one. Thinner 6 mm systems suit walls, backsplashes, and overlays. Against Ordinary Porcelain Tile Twelve millimeters equals approximately 0.47 inches. A nominal 9 mm porcelain tile is 3 mm thinner, so 12 mm is approximately 33 percent thicker than a nominal 9 mm tile. That comparison is useful for buyers accustomed to ordinary porcelain flooring and wall tile: a 12 mm slab is a substantially thicker panel, and that thickness is part of why it can carry countertop fabrication — mitered edges, cutouts, and built-up profiles — that tile cannot. Things to look out for in this comparison: some suppliers make 9 mm tile and some make it thinner — that is usually the case — so the comparison is against a nominal 9 mm tile, not against every tile. And 33 percent greater thickness does not automatically mean 33 percent greater strength; strength depends on the material, the test, and the assembly, and Chapter 3 gives the tested figures rather than a ratio. Figure 2-1. The three gauges as slabs: nominal 9 mm tile, 12 mm slab, and 20 mm slab, drawn to relative thickness. Thickness only; no strength claim. Against 20 mm: Less Material, Same Care Twelve millimeters is 40 percent thinner than 20 mm. For equal-size slabs of comparable material density, that means proportionally less mass to move, cut, and support — roughly 40 percent less material in the panel — which means, in practice: less mass to transport, store, and set; lower dead load on the supporting assembly; less material depth to cut through; and slimmer installed profiles. Those are real advantages. For planning, a full 12 mm slab weighs about 340 lb — about 565 lb at 20 mm for comparison — varying slightly by design, by our calculations for the full slab. It is a working figure, not a certified weight to the pound, so plan handling, equipment, and support around about 340 lb. Less mass is not the same as light. A full 126 by 64 inch slab at 12 mm remains a heavy architectural product. It requires professional equipment and handling at every stage — transport, storage, cutting, and setting — and it is never a casual or unassisted lift. The weight advantage over 20 mm makes professional handling easier; it does not remove the need for it. Why Some Fabricators Prefer 12 mm For appropriately supported large-format installations, some professional fabricators prefer 12 mm for reasons that follow directly from the thickness: lower slab mass to handle, less material depth to cut through, mitered details fabricated from thinner stock, easier integration into supported architectural assemblies, and slimmer installed profiles. Cutting a thinner panel presents less material depth to the blade, which is a straightforward geometric fact. What this guide does not claim is any guaranteed blade-life saving, production-speed improvement, or reduced tool wear: blade performance also depends on the porcelain composition, the blade specification, the machinery, the feed speed, and the cooling. A shop that promises one should be asked for its evidence. Tested Performance & Material Properties Verified results first, plain-English explanations second. Our 12 mm porcelain is supported by documented material testing covering water absorption, strength, thermal behavior, chemical resistance, and stain resistance. The following results explain how the material performs and what buyers should consider when selecting it for a project. Each row below names the property, the result, and the method, so a technical reader can verify it rather than take our word for it. These are family values: they describe the 12 mm porcelain line tested as a family, and your fabricator confirms the details for your specific slab and assembly. Where a project specification requires a product-specific test report, ask for that report rather than assuming a family value covers it. Property Result for our 12 mm porcelain Method / basis Water absorption 0.02% (reported result), well below the 0.5% classification threshold ISO 10545-3; threshold E ≤ 0.5% for Group BIa porcelain Breaking strength, 12 mm At least 4,500 N ISO 10545-4, family value Modulus of rupture At least 45 N/mm² ISO 10545-4, family value Deep abrasion At most 175 mm³ ISO 10545-6, family value Thermal expansion 6.3 × 10⁻⁶ °C⁻¹ ISO 10545-8, family value Thermal shock Pass ISO 10545-9, family value Moisture expansion Less than 0.1 mm/m ISO 10545-10, family value Crazing resistance Pass ISO 10545-11, family value Frost resistance Pass ISO 10545-12, family value Chemical resistance Household and pool-solution agents class A; low-concentration acids/alkalis LA for some finish families, minimum LB for the others; high-concentration minimum HB ISO 10545-13, finish-group dependent Stain resistance Class 5 ISO 10545-14, family value Dimensions Tested and complying ISO 10545-2; tolerance confirmed per slab and assembly Water Absorption: What 0.02% Means, and What It Does Not We report a water absorption result of 0.02% for our porcelain — a very low figure, well below the conventional 0.5% threshold that defines the lowest-absorption porcelain classification. Low absorption drives three practical results: stain resistance, wet-room service, and candidacy for appropriately specified exterior use. Five distinctions govern how far that figure reaches, because each one is a different question. First, the figure describes the porcelain body, not the slip resistance of the finish you choose. Second, it does not make an installation waterproof: waterproofing is a property of the assembly — membranes, joints, drainage, and detailing — not of the slab alone. Third, freeze-thaw performance is a separate tested property (it passes under ISO 10545-12); absorption alone does not approve an exterior assembly. Fourth, suitability of the complete installed assembly depends on the product, finish, exposure, substrate, and installation system together. And fifth, the figure is our reported result for the porcelain; where a specification demands a product-specific report, confirm that report for your slab rather than treating a family figure as a per-slab certificate. Strength, Heat, and Chemical Resistance in Plain English Breaking strength of at least 4,500 newtons for a 12 mm panel, with a modulus of rupture of at least 45 newtons per square millimeter, means the panel carries tested strength for handling, fabrication, and installed service — not a promise that a slab cannot break. Porcelain is strong in place and unforgiving of a rushed cut, a point load, or an unsupported span, which is why Chapters 7 and 10 treat support and fabrication as assembly decisions rather than afterthoughts. Thermal-shock and frost passes mean the material itself handles temperature swings in testing; the installed assembly still needs joints, drainage, and movement accommodation designed for your climate and exposure. Chemical and stain results mean household agents and pool solutions at class A, with the finish-group variation stated in the table — check the class for your finish rather than assuming one class covers all of them. Dimensions are tested to ISO 10545-2 and comply; the tolerance for your specific slab and assembly is confirmed with your fabricator. Indoor Air, Food Contact, and Marking Our porcelain carries a French VOC class A+ rating — the highest class in the French volatile-organic-compound labeling system — across all collections. It carries NSF/ANSI 51 for food equipment materials, valid while the listing is maintained, and a European food-contact declaration under the EU food-contact framework, along with CE marking. These credentials matter in the order a buyer actually encounters them: indoor air for the home, food-contact suitability for kitchen surfaces, and marking for the product's declared conformity. None of them is a substitute for the assembly decisions in Chapters 7 through 11. Environmental Transparency: The EPD, Stated With Its Scope Our porcelain is covered by an independently verified Environmental Product Declaration (EPD) for porcelain stoneware surfaces, assessed under the construction-products rules EN 15804+A2 with the ceramic-tile complementary rules, and valid to October 2029. An EPD is a standardized, third-party-verified lifecycle declaration: it reports environmental indicators for a defined product scope so buyers can compare products on the same basis. An EPD is environmental documentation, not a product-performance certification: it describes environmental indicators, not how the slab performs in service. The scope matters here, and we state it plainly: that declaration covers 6.5 mm porcelain stoneware surfaces. It describes the lifecycle-assessment practice for the product family; it is not a declaration for 12 mm slabs, and this guide does not present it as one. If a project requires a 12 mm declaration, that is a question to raise with us before specification, not an assumption to carry into a bid. Kitchens Countertops, islands, backsplashes, range-hood cladding, and waterfall legs — where 12 mm does its best work. Countertops and Islands The kitchen countertop is where 12 mm earns its keep. Two 45-degree cuts in 12 mm stock join into a mitered edge, so a countertop can carry a thick, furniture-like profile built from 12 mm stock. Settle seam locations early. With a 126 by 64 inch slab, seams are fewer than with smaller formats, but a long island or an L-shaped run will still have them. Decide where they fall while you can still choose, and confirm how the shop finishes them and how the book-match reads across them. Before you hire a shop, look at a mitered edge it built in porcelain: the edge is the clearest evidence of a porcelain shop, because it shows the cutting, the joint, and the finishing together. Figure 4-1. A mitered edge: two 45-degree cuts in 12 mm stock joined to form a thick built-up countertop edge, shown with the supporting assembly beneath. Pattern Continuity at the Miter A mitered edge reads as one thick panel only if the design continues around the joint. Whether it does depends on how the design is made: some porcelain designs carry their pattern through the body, while others carry it as a surface treatment, and a surface design will not continue through the body at a miter. Confirm the construction of your design before assuming a continuous edge, and confirm with your fabricator how the joint will read for that design. The adhesive, the joint finish, and the edge profile all belong in the written quote. Full-Height Backsplashes A full-height backsplash in the same design as the countertop shows 12 mm at its best: fewer grout joints, large-format continuity from counter to upper cabinets, and no material change at the most visible wall in the kitchen. The 12 mm porcelain body is 8 mm thinner than a 20 mm body before adhesive, substrate, and trim — and that thinner body simplifies outlet, trim, and countertop-to-backsplash details, because there is less material depth to work around. The finished installed depth difference is not always exactly 8 mm: adhesive beds, substrates, and trim vary by assembly, so confirm the installed depth for your assembly rather than assuming the body difference is the finished difference. Full-height runs also need the framing behind them confirmed to carry full slabs, and the seam plan settled before fabrication, since a tall run may need more than one panel. Range-Hood Surrounds and Cladding Wrapping an appropriately designed kitchen range-hood enclosure in matching porcelain carries the countertop and backsplash design up the wall and turns the hood into part of the architecture rather than an appliance interruption. It is a professional design application, not a default: not every hood can be clad, and the decision requires confirmation of the exact product and assembly before anyone orders material. The points to settle, in order: design continuity (does the hood panel align with the backsplash seams and the countertop design, and does the pattern read correctly across the enclosure faces); the slimmer material profile (12 mm keeps the enclosure face thinner than a 20 mm build, which matters where the hood sits close to cabinetry or a mantel line); weight and support (the enclosure structure must be confirmed to carry full panels, including any cantilevered or projecting faces); heat and clearance (the hood manufacturer's instructions and the applicable clearance requirements govern — cladding does not reduce a required clearance, and heat exposure at the enclosure must be confirmed for the exact hood and cooking arrangement); ventilation and maintenance access (panels must not block access the hood needs for service, filters, or ductwork); and fire-rated assemblies where applicable (where the wall or enclosure is part of a rated assembly, the cladding system must be confirmed against that rating — a decorative panel is not a fire rating). Where any of those points cannot be confirmed for your hood, the honest answer is a different enclosure treatment, not a forced clad. Figure 4-2. Porcelain-clad range-hood concept: enclosure, panels, seams, support structure, and clearance zones, with a qualification note on the figure stating that clearances follow the hood manufacturer's instructions and that not every hood can be clad. Waterfall Legs A waterfall leg carries the countertop design straight down the side of an island or peninsula to the floor. It is a mitered joint done vertically, and it exposes both the design and the shop's craft. Support and anchorage for the leg are structural questions, not just visual ones: the leg panel, its footing, and its connection to the countertop and the floor all belong in the written scope, along with how the pattern continues (or does not) around the vertical miter. Confirm all of it before fabrication, because a waterfall leg is difficult to correct after the panels are cut. Figure 4-3. Waterfall island detail: countertop panel, vertical leg panel, miter joint, footing, and anchorage, with a note on pattern continuity at the vertical joint. Sinks and Cutouts Sink and cooktop cutouts are the most stressed parts of a countertop, which is why inside corners are rounded rather than cut sharp: sharp corners concentrate stress. Settle sink mounting and cooktop cutouts early, because the cutout and the support around it affect the whole countertop. No single mounting or reveal suits every sink: a flush-mounted undermount at zero reveal stops the slab edge at the sink, while a negative reveal carries the slab edge into the sink opening, and each option has different fabrication, maintenance, clearance, and edge-exposure considerations. Your qualified fabricator confirms the appropriate mounting and reveal for your sink, your edge profile, and your maintenance expectations — that confirmation, with the cutout locations, belongs in the written quote. Support Under the Countertop Support under a countertop is an assembly decision, not a universal figure. Systems differ in how they handle it: continuous substrates, cabinet support, reinforcing elements, and permissible spans all vary by system, span, and layout. There is no single number that covers every kitchen, and this guide does not invent one. What belongs in every project is a written support method for every countertop run and every overhang: which system, which spans, which reinforcing elements, and who confirms them. If a quote does not name the support method, the quote is not finished. Where no approved system is documented for your assembly, do not assume one — confirm it with the fabricator and with us before fabrication begins. Bathrooms and Interiors Floors, shower walls, vanity tops, and full-height walls — with finish and waterproofing kept distinct. Bathroom Floors A bathroom floor is a wet floor, so the finish decision matters more here than anywhere else. Specify a textured finish, confirm slip suitability for the finish you choose with your installer, and confirm the grout plan — grout lines are the part of a bathroom floor that needs ongoing care, while the slab body ordinarily does not require routine sealing. A large-format floor also means fewer grout lines to clean. No finish in this guide is presented as suitable for every wet floor: confirm the finish for your room, your drainage, and your exposure. Shower Walls Shower walls show large format at its best in a bathroom: one design running with minimal joints, less grout to maintain, and a surface that handles daily wetting. The slab is not the waterproofing system. Membranes, joints, drainage, and detailing behind and around the panels are what keep water out of the wall, and they belong to the installer's assembly design, confirmed in writing before panels are set. Where a shower wall is a full-height run, the framing behind it must be confirmed to carry full slabs before the slabs arrive. Vanity Tops and Full-Height Walls Vanity tops follow the kitchen rules at smaller scale: mitered edges, cutouts for basins, support beneath, and seams placed deliberately. Sink assemblies need the same treatment as kitchen sinks — mounting and reveal confirmed with the fabricator for the basin, the edge profile, and maintenance — and the support beneath the vanity top belongs in the written scope. Full-height walls are the dramatic move: a single design running floor to ceiling, book-matched across seams. Tell your installer about full-height walls early so the framing behind them is confirmed to carry full slabs. Weight is not a reason to avoid the look; it is a reason to plan the framing before the slabs arrive. Floors Through the House Interior floors show continuity at its best: one design flowing from room to room, with fewer grout lines and no material change at thresholds. Two substrate principles decide whether a floor succeeds. First, the substrate must be flat and stiff enough for large panels — your installer checks this before quoting, not after setting. Second, if radiant heat is planned or present, the full assembly must be designed for thermal cycling: porcelain conducts heat well and performs over radiant systems when the assembly is designed for thermal cycling, so confirm the installer's method for temperature change in writing. From an interior floor straight out onto a patio, the same continuity is possible only as a bonded assembly designed for exposure, drainage, and temperature change, with a finish confirmed suitable for the exterior walking surface — see Chapter 6. Outdoors and Architectural Cladding Bonded outdoor surfaces — and where pavers, fascia, and engineered systems take over. Where 12 mm Goes Outside Our 12 mm slabs carry a general rating for interior and exterior surfaces, and they belong outside in bonded assemblies designed for the exposure: patios, outdoor kitchens, and pool surrounds where the slab is fully bonded to a prepared substrate. The freeze-thaw and thermal-shock testing behind the slab supports that use — the material handles temperature swings in testing. The assembly decides whether it holds up: your installer designs the bonded assembly for exposure, drainage, and temperature change, and that design belongs in the written scope before work begins. A bonded outdoor surface is a system, not just a slab laid outside. That general rating is not a per-application approval. Bonded use requires confirmation of the specific product, the finish, the exposure, the substrate, and the installation system together. Wet walking surfaces need particular care: confirm slip suitability for the finish on that surface, in that exposure, before anyone orders material. Pool surrounds add chemical exposure and constant wetting to the same questions. Where any element cannot be confirmed for your project, the honest answer is a different product or system, not a forced approval. Drainage and Joints, Briefly Drainage and joints decide whether an outdoor bonded assembly lasts: water must leave the surface, joints must accommodate movement, and the substrate must stay stable through wetting and temperature cycles. Those three items belong in the written scope for every outdoor job, alongside the product and finish confirmation. If a quote describes an outdoor slab without naming drainage, joints, and movement accommodation, it is not a complete outdoor quote. Fascia and Architectural Cladding: Keep the Systems Distinct Architectural cladding is where careful language matters most, because several different systems share the word "cladding" and they are not interchangeable. Interior decorative cladding is a panel fixed to an interior wall for appearance, where the wall behind it carries the load. Exterior fascia is a panel applied to a building face for appearance and weather protection, where the fixing and the substrate must suit the exposure. An engineered facade or rainscreen system is a designed assembly — panels, supports, ventilation, drainage, and fixings engineered together, often with mechanical support. A mechanically supported system carries panels on rails, anchors, or frames rather than on adhesive alone. A fully bonded installation adheres panels directly to a prepared substrate, and it is appropriate only where specifically approved for that product, substrate, and exposure. Do not transfer one manufacturer's exterior-system approval to another product, and do not read a general exterior rating as an approval for every wall system. Where no facade approval for our slabs is documented for your system, the design discussion stays conditional: the project requires verification from us and the project engineer for the exact product, panel size, fixing method, and exposure before specification. That verification is part of the design, not an obstacle to it. Figure 6-1. Exterior architectural detail: a bonded panel assembly beside a mechanically supported rainscreen assembly, with supports, ventilation, drainage, and fixings labeled, and a note stating that the bonded detail applies only where specifically approved.

What Your Fabricator Does Cutting, edging, seams, and support — the craft behind the finished surface. Cutting and Edging Fabrication is where a slab becomes a countertop. The shop saws the slab to size, cuts openings, shapes and profiles the edges, and joins mitered edges into thick profiles. All of it is done wet, for reasons Chapter 9 covers, and all of it is done on material that behaves like glass until it is installed: strong in place, unforgiving of a rushed cut. Cutting 12 mm presents less material depth than cutting 20 mm, which is one reason some shops prefer the gauge — and it is not a reason to rush. Feed speed, blade selection, cooling, and the shop's porcelain experience decide the quality of the cut far more than the thickness alone. Seams Seams deserve a conversation, not a surprise. Confirm where they will fall, how they will be finished, and how the book-match reads across them. A well-placed seam disappears into the design; a poorly placed one interrupts it. The time to decide is during the quote, when moving a seam costs nothing. Cutouts and Corners Sink and cooktop cutouts are the most stressed parts of a countertop, which is why inside corners are rounded rather than cut sharp. Confirm the shop's cutout practice — how it rounds corners, how it supports the span around a sink, and what it does differently for porcelain than for other stones. The answers tell you quickly whether you are talking to a porcelain shop. Support and Substrates Countertops need their support method named in writing. Floors need substrates that are flat and stiff. Walls need framing confirmed to carry full slabs. None of these has a single universal figure, because each depends on your layout, your home, and your fabricator's and installer's systems. What you should demand instead is written confirmation: support, substrate preparation, and framing, all named in the quote. A quote that names them is a quote you can hold someone to. For mesh-backed slabs, confirm adhesive compatibility and preparation with the fabricator and with us: the backing is part of the assembly, and the adhesive and preparation method must suit it. No specific adhesive product is named in this guide — the confirmation itself is the requirement. Fiberglass Mesh Backing What the backing does, what it does not do, and what to confirm about adhesives and preparation. Our 12 mm porcelain slabs feature fiberglass mesh backing bonded to the underside of the slab. This reinforcing layer is intended to assist handling and fabrication and help retain fragments if a panel breaks. It provides added reassurance during work with large-format slabs, but it does not make the porcelain unbreakable or replace appropriate support and installation methods. The backing measures approximately 1–1.5 mm thick by our observation. Mesh backing is not an industry requirement for porcelain slabs, but we include it because fabricators appreciate the easier handling it gives our porcelain and the added safety element if a panel breaks. Figure 8-1. Fiberglass mesh backing cross-section, showing the porcelain body (12 mm), the mesh backing layer, and the adhesive/preparation zone. The figure carries the qualification on its face: the mesh is a helper layer, not the structure; it does not replace support, framing, or anchorage. The illustration is conceptual and not to scale; the backing measures approximately 1–1.5 mm thick by our observation. The limits are just as important. The mesh is a helper, not the structure. It does not make a slab unbreakable, and it does not replace proper handling, support, attachment, waterproofing, or engineering. A mesh-backed panel still needs the support method in Chapter 4, the framing in Chapters 5 and 6, and the waterproofing assembly in Chapter 5 — the mesh helps within those assemblies; it does not substitute for any of them. This guide claims no fire rating, no structural capacity, and no specific fragment-retention performance for the mesh. If a project specification requires any of those, that is a documentation question to raise before specification, not a property to assume. Two practical confirmations belong with the mesh. First, adhesive compatibility: the adhesive and preparation method must suit a mesh-backed panel, and your fabricator confirms both with us for your assembly — the confirmation is the requirement, and no specific adhesive product is named here. Second, preparation: the backing must be prepared as the fabricator's and our method directs before setting; a panel set with the wrong adhesive or the wrong preparation is a panel set on an assumption. Both confirmations belong in the written scope. Safe Fabrication and Dust The brief version: professional shops, wet methods, and exposure controls. Cutting and grinding porcelain can create hazardous airborne dust, including respirable crystalline silica. That is why fabrication belongs in a professional shop with exposure controls, not on site with a dry saw. A shop doing this work properly uses wet cutting methods, ventilation and localized extraction, wet or HEPA-filtered cleanup (never dry sweeping or compressed air on dust), and respiratory protection selected for the task — under the existing California and federal silica requirements that govern this work, including the permissible exposure limit of 50 micrograms per cubic meter and the action level of 25 micrograms per cubic meter as 8-hour time-weighted averages. The details of a shop's exposure plan, housekeeping, and respirator program belong in your conversation with the shop: a shop that explains its dust plan without being asked is a shop that takes the work seriously. Intact installed panels present no known dust hazard in normal use; the hazard is in cutting, grinding, and polishing, which is exactly where the controls apply. This section is deliberately brief: it states the hazard, the controls, and the existing limits, and it leaves the shop's plan to the shop — verified in writing, not assumed.

What Must Be in Your Fabrication Quote A finished quote names: the design, finish, and quantity of slabs; edge profiles and mitering, including waterfall legs where planned; seam locations and finishing, and book-matching; cutout locations, sink mounting, and reveal details; the support method for every countertop run and overhang; substrate preparation and framing confirmation; adhesive compatibility and preparation for mesh-backed slabs; the dust plan for fabrication; the waterproofing assembly for wet rooms; drainage, joints, and movement accommodation for outdoor work; and the system verification for any fascia or facade work. Compare written scopes, not headline prices: two quotes that name different scopes are not comparable, and the cheaper one is usually the one that left something out. Qualify Your Fabricator and Installer The questions that separate a porcelain shop from a general stone shop. Meet three or more shops. Porcelain fabrication is a specialty: the cutting, the mitering, the dust controls, and the assembly details differ from other stones, and a general stone shop's reputation does not transfer automatically. The five questions below each start with why the question matters, so you can judge the answer rather than just collect it. Show me a mitered edge you built in porcelain. The edge is the clearest evidence of a porcelain shop: it shows the cutting, the joint, and the finishing together. A shop that cannot show one has not done this work at the level your project needs. How do you support this countertop, run by run? Support is assembly-specific, so a good answer names the system for your spans and layout — continuous substrate, cabinet support, reinforcing elements, or a combination — rather than a slogan. A vague answer is a red flag. What is your dust plan? Wet methods, extraction, cleanup, and respiratory protection under the existing exposure limits (Chapter 9). A shop that explains its plan without being asked is a shop that takes the work seriously; a shop that dismisses the question is not. How do you handle seams, book-matching, and cutouts for this design? Seam placement, finishing, book-matching, cutout rounding, and sink mounting and reveal — all decided during the quote, when moving a seam costs nothing. What exactly is in your written scope, and what is not? Support, substrate, framing, adhesive compatibility for the mesh backing, waterproofing for wet rooms, drainage and joints outdoors, and system verification for fascia or facade work. Compare scopes, not prices. Red Flags A quote with no support method named. A shop that cannot show a porcelain miter. A dust plan that amounts to dry cutting. A promise that every finish suits every wet floor, every slab suits every exterior wall, or every hood can be clad. A price that undercuts every competitor by leaving scope out. Any of these is a reason to keep interviewing, not a reason to negotiate the same shop down. Frequently Asked Questions Can 12 mm really be a countertop? Yes. Twelve millimeters is the gauge we build this guide around for countertops, floors, and walls in one material — not because thinner gauges cannot serve a countertop in some systems, but because 12 mm balances thickness, mass, versatility, and fabrication for the widest range of projects. Mitered edges give a countertop a thick, furniture-like profile built from 12 mm stock, and the support method for every run completes the assembly. The gauge is only half the story — the fabricator's craft is the other half, which is why Chapter 11 matters. How much lighter is 12 mm than 20 mm? Twelve millimeters is 40 percent thinner than 20 mm, so at equal size and comparable density it carries proportionally less mass — roughly 40 percent less material to move, cut, and support. For planning, a full slab weighs about 340 lb (Chapter 2), and still requires professional equipment and handling. What does the 0.02% water absorption figure mean? It is our reported result for the porcelain body: very low absorption, well below the conventional 0.5% classification threshold. It supports stain resistance and wet-room and exterior candidacy, but it does not make an installation waterproof, does not set a finish's slip resistance, and does not approve an assembly on its own. Chapter 3 states all five distinctions. Does porcelain need sealing? The dense porcelain body ordinarily does not require routine sealing. Grout lines are a different story: where slabs meet grout, the grout itself needs the care your installer recommends, and joints, backing, adhesives, and finish-specific maintenance instructions are separate. Maintenance stays simple when the distinction holds: wash the slab, care for the grout, and follow your installer's care guidance for the rest. What does the mesh backing do? The fiberglass mesh backing — approximately 1–1.5 mm thick by our observation — helps during handling and fabrication, and helps hold fragments together if a slab is ever damaged. It does not replace support, framing, or anchorage, and it does not make a slab unbreakable. Think of it as a helper layer, not the structure. Chapter 8 gives the full account, including what is not claimed for it. Can one design run through kitchen, bathroom, and patio? Yes — kitchen countertops, bathroom floors, shower walls, and bonded outdoor surfaces can all carry one design in 12 mm, provided each application is confirmed for its product, finish, exposure, substrate, and system. Plan the rooms together, confirm availability of the quantity you need early, and tell your fabricator where you want book-matching. Where do 20 mm pavers belong instead of slabs? In bonded assemblies designed for exposure, drainage, and temperature change — patios, outdoor kitchens, and pool surrounds — 12 mm slabs belong. Roof decks, balcony decks, and dry-laid patios typically use 20 mm pavers instead, on pedestal systems, mortar beds, or compacted beds. Your installer confirms which category your project falls into. Who does what on my project? We supply the full slabs. Your fabricator measures, templates, cuts, edges, and miters. Your installer sets the panels and owns the substrate, framing, waterproofing, and exterior-assembly confirmations.

Sources And Our Role The Correct Sequence Do Not Template A Project That Is Still Changing Countertop projects fail when stages overlap. Do not template a project that is still changing. A template turns the room into fabrication data. A moved island, a revised sink, a different cooktop, or a late edge change can invalidate that data and force a new template, a recut, or another slab. Control the order below and do not approve the next stage while the previous stage is still moving. Cabinets Complete — Cabinet boxes and islands are permanently fastened. Finished panels, fillers, scribes, and final appliance positions are set. Pick Out Slabs — Reserve your exact slabs. Bring your final cabinet sample, flooring selection, hardware, and room photos to compare against full slabs at our showroom. Template — Your fabricator records exact field measurements only after the room stops changing. Slab And Layout Approval — Approve vein direction, seam locations, cutouts, edge profile, and the full slab map in writing before anything is cut. Fabrication — The shop cuts, edges, and finishes your pieces from the approved layout. Countertop Installation — The crew sets the stone on cabinets that are already level, true, and ready. Plumbing And Appliance Reconnection — Licensed trades reconnect the sink, faucet, disposal, gas, and electrical. Backsplash And Final Touchups — The backsplash goes in after the counters. Paint and drywall touchups close the project. Before Template Choose the material around actual heat, sun, edge, and cleaning conditions. Fix cabinets, panels, fillers, appliance locations, and island position. Have the exact sink and appliance data available. Approve the support approach for overhangs, sinks, and thin slab edges. Before Cutting Reserve the exact slabs and record thickness, finish, lot, and sequence. Approve vein direction, seams, cutouts, edge profile, and backsplash scope. Confirm the fabricated pieces can reach the room. Keep one written release sheet signed by the decision maker. The Controlling Rule. Do not approve the next stage while the previous stage is still moving. Where We Stop. We supply the slab and help you compare materials. The independent qualified fabricator and installer must verify every site measurement, cut, support condition, and installation detail before work begins. Choose By Use Color Comes After Performance Start With The Room, Not The Pattern. Quartz, porcelain, and sintered stone can all deliver a premium surface. They are not interchangeable. The correct choice depends on exposure, heat, edge design, thickness, and the fabricator who will execute the work. Best fit Quartz: Indoor kitchens and baths with familiar fabrication and broad edge options. Porcelain: Indoor or outdoor counters, walls, fireplaces, and thin profile design. Sintered stone: Demanding indoor or outdoor counters with strong heat and UV requirements. Direct sun Quartz: Covered use only. Avoid direct sunlight. Porcelain: Suitable for exterior use on our product pages. Sintered stone: UV stable and intended for exterior use. Heat strategy Quartz: Use trivets. Resin makes extreme heat a risk. Porcelain: High heat tolerance. Confirm details for the exact product and assembly. Sintered stone: High heat tolerance from a resin free mineral body. Confirm the exact product. Typical listed format Quartz: 126 by 64 inches, 20 mm. We also offer 138 by 79 inch super jumbo quartz in selected stock. Porcelain: 126 by 64 inches, 12 mm. Sintered stone: 126 by 64 inches, commonly 12 mm or 20 mm depending on product. Edge planning Quartz: Solid body supports a broad range of profiles. Porcelain: Thin body often uses a precision miter for a thicker look. Sintered stone: 12 mm often uses miters. 20 mm can support more traditional profiles. Fabrication Quartz: Qualified quartz fabricator. Porcelain: Specialist handling, wet continuous rim diamond tooling, precise miters. Sintered stone: Specialist diamond tooling, waterjet or computer controlled cutting where needed. Do not select from this comparison alone. Confirm the exact product page, slab thickness, finish, warranty, and approved application before purchase. Product availability and specifications can vary by design. Quartz The Direct Indoor Choice Quartz is the practical route when the project is indoors, the edge profile matters, and the household wants a nonporous surface that never needs sealing. Use It When The counter is indoors and away from prolonged direct sun. You want a traditional polished edge, rounded profile, or built up edge detail. You prefer simple daily cleaning with mild soap, water, and a soft cloth. You need a broad range of marble inspired and solid color options. Control These Risks Quartz is heat resistant, not heat proof. 300 degrees is the maximum before discoloration. Use a trivet or hot pad, and never set a pan straight from the oven on the surface. Do not use quartz for direct outdoor sun unless the exact product is approved for that condition. Never cut directly on the surface. Do not add sealer or polish. It is unnecessary and can create an uneven finish. Know The Standard Listed Spec Slab: 126 by 64 inches on current quartz product pages. Thickness: 20 mm, also stated as 2 cm. Finish: Semi polished on the reviewed product pages. Super jumbo is a yield tool. Our super jumbo quartz offering measures 138 by 79 inches. Confirm that size against the exact selected stock before the fabricator plans a one piece island. Homeowner Decision. Choose quartz when a protected indoor location, flexible edge design, and simple maintenance matter more than direct sun or extreme heat performance. Porcelain Thin Profile, Broad Application Our porcelain is listed for interior and exterior surfaces. Its 12 mm body suits counters, full height backsplashes, shower walls, fireplaces, and cladding where a lighter visual profile is part of the design. Use It When The project includes outdoor exposure or strong sunlight. Heat resistance is a primary selection factor. The design needs large wall panels or a slim edge. A mitered edge or waterfall can be fabricated by a qualified specialist. Control These Details Thin slabs need deliberate support, transport, and jobsite handling. A thicker visual edge usually requires a precise 45 degree miter and a color matched adhesive. Pattern is printed at the surface, so edge transitions must be planned rather than assumed. Cutouts require correct wet tooling and an experienced porcelain fabricator. Our Porcelain Advantage. Our 12 mm porcelain does not require perimeter tension relief cuts or sealing. More of the slab can remain usable, but the fabricator still needs approved tooling and handling methods. Listed Spec Slab: 126 by 64 inches. Thickness: 12 mm, also stated as 0.5 inch. Use: Interior and exterior on reviewed product pages. Sealing: Not required. Homeowner Decision. Choose porcelain when direct sun, heat, wall coverage, a thin architectural profile, or a surface that never needs sealing matters. Confirm the project with an independent fabricator experienced in large format porcelain. Sintered Stone Resin Free Performance Sintered stone is formed from mineral powders under pressure and kiln heat. It contains no resin binder, remains stable in direct sun, and is intended for high performance indoor and outdoor work. Use It When The counter is outdoors or receives prolonged direct sun. The design includes a fireplace surround or a heat intensive cooking zone. Near zero porosity and no sealing are priorities. The project needs a matte, natural, soft, silk, or polished visual direction, subject to product availability. Control These Details Dense mineral construction requires specialist diamond tooling and careful fabrication. Match thickness to the edge, sink, support, and outdoor assembly. Plan miters, cutouts, and handling before the slab is released. Do not treat a general heat statement as permission to ignore the exact product and installation instructions. Why Thickness Matters. We specify 12 mm slabs for counters and full height backsplashes, while 20 mm slabs support heavier outdoor work, traditional edge profiles, and more complex sink conditions. Listed Spec Slab: 126 by 64 inches on reviewed products. Thickness: 12 mm and 20 mm across the collection. Use: Interior and exterior. Homeowner Decision. Choose sintered stone when exterior exposure, UV stability, resin free construction, and strong heat performance outweigh the need for conventional quartz fabrication. Cabinets And Template The Slab Follows The Base Cabinets Control The Quality Of The Install. The cabinet run must be permanent, stable, and accurate before the fabricator records the template. We require cabinet tops to be flat and true within 1/16 inch across 18 inches. Check flatness across 18 inches. Provide front to back support every 18 to 24 inches. Close These Conditions Cabinet boxes and islands are permanently fastened. Finished panels, skins, fillers, scribes, and decorative legs are installed. Walls are at the final measurable plane. Overhang support is approved before fabrication. Doorways, stairs, turns, elevators, and staging space are checked. Have These Items On Site The exact sink and drain position. Cooktop model and cutout drawing. Faucet, air switch, soap dispenser, and filtered water details. Appliance panels and final appliance clearances. Approved support rails or sink setter system. Do not force stone to correct cabinetry. Fix a low, twisted, or moving base first. The countertop should arrive to a structure that is already ready to receive it. Site Approval Belongs To The Installer. We can help you choose quartz, porcelain, or sintered stone and reserve the slabs. We do not take field dimensions or determine site support. Your independent qualified fabricator and installer must approve the cabinets, template, access, support, and final installation method. Slab Yield And Layout Area Is Only The First Number Buy For Slab Yield, Not Square Footage. The fabricator must fit each piece inside the usable slab while protecting vein direction, cutout strength, edge buildup, seam logic, and safe handling. A quote can have the correct area and still have the wrong slab count. Record The Exact Slab Product name and stock keeping unit. Actual dimensions and thickness. Finish, lot, and slab sequence. Number of slabs reserved. Book matched order when selected. Any visible area that must be excluded. Approve The Visible Plan Vein direction across island, perimeter, backsplash, and waterfall. Seam location and pattern alignment. Sink and cooktop position within the pattern. Edge buildup, overhangs, and finished ends. Every piece labeled on a photo or digital slab map. Approval Standard. The person paying for the work and the person cutting the slab should approve the same visual map. Keep that approval with the project record. Fabrication And Support Details Carry The Load Cutouts, Edges, And Support Need Written Dimensions. Our Quartz Fabrication Baseline Inside corners: minimum 3/8 inch radius at sinks, cooktops, and shaped tops. Cutout clearance: an extra 1/8 inch between the fixture and cutout edge. Edge: minimum 1/8 inch bevel. We prefer a 1/8 inch pencil round. Cutting: wet diamond tools. Start cutouts with a core bit and avoid cross cutting. Polishing: wet polish edge details only. Do not polish the factory face. Support The Surface Provide perimeter support with a full deck where specified. Provide front to back support every 18 to 24 inches. Have the fabricator specify support for every overhang. Support every sink independently from the countertop. Fasten Without Stress For quartz, use dabs of flexible 100 percent silicone spaced 8 to 12 inches apart. Never drive nails or screws into quartz. Groove seam edges for adhesive and use a compatible pigment match. Place extra adhesive at corners and joints as required by the fabrication plan. Material changes the fabrication method. These dimensions are our quartz guidance. Porcelain and sintered stone need product specific cutting, edge, and support details from a fabricator qualified for that material. Choose A Fabricator Who Controls Silica Dust OSHA and the National Institute for Occupational Safety and Health identify respirable crystalline silica as a countertop fabrication hazard. Ask whether the shop follows the applicable silica standard, uses wet cutting and wet polishing at the point of contact, adds local exhaust when needed, and avoids uncontrolled dry cutting or grinding. A code minded fabricator should also be able to explain its exposure assessment, written control plan, wet or high efficiency particulate air housekeeping, equipment maintenance, training, and respiratory protection when required. That discipline is a useful signal that the work will be planned rather than improvised. One-Piece L-Shapes An L-Shaped Corner Is A Stress Decision A One-Piece L Is A Conditional Fabrication Choice. A one-piece L removes a corner seam, but it also creates one rigid piece with an inside corner that must survive cutting, handling, transport, and installation. Do not approve it from the short-leg dimension alone. One continuous piece with a rounded inside corner and a 3/8 inch minimum radius means no sharp inside corner. When two pieces meet at the inside corner, the seam falls at the corner and no corner radius is required there. A One-Piece L May Be Considered Only When The full shape fits within the verified usable area of the exact slab. The inside corner can be formed with a minimum 3/8 inch radius. The fabricator can core-drill the corner, avoid cross-cutting, and use wet diamond tools without damaging the drilled area. Sink, cooktop, faucet, and other openings leave enough material around the L corner. The specified cabinet and substrate support continues through both legs and the corner. The piece can be transported, turned, carried, and set without twisting or flexing. A Corner Seam Is Usually The Safer Plan When The return is a full-depth counter rather than a small or shallow return. A sink, cooktop, notch, or another stress point is close to the inside corner. The one-piece geometry creates poor slab yield or forces an unacceptable pattern layout. Doors, stairs, elevators, turns, or staging make one-piece handling difficult. The cabinets or support plan cannot provide reliable bearing through the full L. The fabricator will not accept and warrant the one-piece fabrication and installation plan. There is no universal short-leg cutoff. Published quartz fabrication manuals do not all use the same rule for one-piece L-shapes. For our quartz, the controlling minimum is a 3/8 inch radius at every unseamed inside corner. A short leg by itself does not make the piece acceptable. Require A Written Go / No-Go Decision. Before layout approval, ask the independent qualified fabricator and installer to mark the drawing as one piece or seamed, show the radius or seam, confirm nearby cutouts, support, transport path, and installation method, and state that the selected plan is covered by their workmanship warranty. We supply the slab; we do not approve the field fabrication or installation plan. Flush Mounted Sink The Sink Is The Highest Impact Cutout A Flush Mounted Sink Reduces Direct Impact At The Stone Edge. A rectangular undermount sink is standard in many United States kitchens. With a negative reveal, the stone cutout continues past the sink wall and projects into the basin. With a flush, zero reveal, the stone stops just before the sink wall and does not carry into the sink. On a compatible flush mounted sink, the stainless steel rim finishes level with the countertop and helps receive direct impact before the stone edge. Negative reveal undermount, side section: the stone carries into the sink. The finished stone edge projects into the basin because the stone overhangs the sink wall. Flush, zero reveal undermount, side section: the stone does not carry into the sink. No finished stone edge projects into the basin because the stone stops at or just before the sink wall, with the metal rim and no stone overhang. Why Flush Mount Helps The stainless steel flange acts as a bumper around the working edge. Heavy cookware reaches the metal rim before the finished stone edge. The stone stops just before the sink wall, so no stone ledge projects into the basin. The level transition removes the hidden underside created by a negative reveal and makes debris easier to wipe into the basin. What It Requires The exact sink must be present before template and fabrication. The machined recess must match the sink flange depth and outline so the rim finishes level with the countertop. The sink needs independent mechanical support. The slab must not carry its weight. The perimeter joint needs compatible 100 percent silicone and periodic inspection. Flush mounted does not mean chip proof. The visual difference is direct: a negative reveal carries stone into the sink, while a flush, zero reveal stops the stone just before the sink wall. Confirm the rectangular sink model, material, slab thickness, flange geometry, and fabricator before template. The sink must remain independently supported and sealed with 100 percent silicone. What Must Be Included In My Fabrication Quote? The Slab Price Is Only One Part Of The Job Two proposals can show different totals because they are not pricing the same scope. Ask each fabricator to mark every line as included, excluded, or priced as an allowance before you compare bids. Measurements, Material, And Fabrication Template / field measurements. Slab pickup and delivery. Demolition and removal of existing counters. Fabrication labor. Sink cutout. Sink mounting and independent support. Faucet and accessory holes. Cooktop cutout. Selected edge profile. Mitered or built-up edges. Waterfall panels. Layout, Installation, And Site Conditions Number and location of seams. Vein and layout matching. Brackets or overhang reinforcement. Full-height slab backsplash fabrication. Countertop installation. Jobsite cutting charges, if applicable. Stairs, elevator, or special access charges. Plumbing and electrical work, or a clear statement that they are excluded. Return trips and change-order rates. Who owns and receives the remaining slab or offcuts. Ask for quantities, not only labels. A complete proposal should identify the number of sink and cooktop cutouts, faucet holes, seams, finished edges, waterfall legs, backsplashes, brackets, and trips included. Compare The Same Scope. Before selecting a fabricator, place the proposals side by side and normalize every inclusion, exclusion, allowance, and access charge. The lowest total is not the lowest price if required work appears later as a change order. Who Is Responsible For What? Responsibility Must Be Assigned Before Template A countertop agreement is not automatically a demolition, plumbing, gas, electrical, cabinet, wall repair, or tile contract. Before the room is templated, mark every task as included or excluded, name the responsible trade, and record who will schedule it. Slab supply — We supply the slabs. Template / field measurements — Independent fabricator. Slab cutting and edge fabrication — Independent fabricator. Countertop installation — Independent fabricator / installer. Existing countertop demolition — Confirm in the fabrication or general contractor agreement. Sink mounting — Typically the fabricator / installer; confirm support and sealing in the contract. Faucet, sink drain, and garbage disposal plumbing — Licensed plumber or other appropriate trade. Gas cooktop connection — Appropriate licensed trade. Electrical connections — Licensed electrician or other appropriate trade. Overhang brackets or structural supports — Cabinet contractor, general contractor, or fabricator / installer, as contracted; approve before template. Cabinet leveling or structural repair — Cabinet contractor / general contractor. Drywall or wall patching — General contractor or drywall trade; confirm separately. Tile backsplash — Tile contractor, unless the fabricator's contract includes it and the fabricator holds the required tile installation license or certification. Full-height slab backsplash — Independent fabricator, if included in the contract. Read the exclusions, not only the proposal total. Scope and licensing requirements vary. Ask each contractor to identify disconnections, reconnections, demolition, hauling, support, repairs, and finish work in writing before work begins. Our Role. We supply quartz, porcelain, and sintered stone slabs and help you compare surface options. We do not take field measurements, fabricate, install, or coordinate trade work. The independent professionals you hire must confirm their own scope, licensing, and site responsibilities. Installation And Care No Design Decisions On Installation Day The Crew Should Arrive To An Approved Room. Before Arrival Clear the route from truck to room. Protect floors, cabinetry, and adjacent finishes. Remove drawers or obstacles requested by the installer. Coordinate water, gas, and power with the proper trades. Keep other crews out of the work zone. Before Signoff Compare each piece with the approved slab map. Review seams and pattern alignment in consistent light. Inspect edges, inside corners, cutouts, and wall clearance. Confirm sink support and seal. Photograph every open item before the crew leaves. Start Care With The Correct Material Rule Sealer: Not required for quartz, porcelain, or sintered stone. Heat: Quartz — use a trivet every time. Porcelain and sintered stone — high heat performance, but follow the product and fabricator instructions. Sun: Quartz — covered only, no direct sun. Porcelain — exterior use listed. Sintered stone — UV stable, exterior use listed. Cutting: Use a cutting board on all three surfaces to protect the finish and your tools. Never cut directly on the surface. Daily cleaning (all three): mild soap, water, and a soft cloth. Wipe spills promptly. For stubborn residue use a non abrasive cleaner approved for the surface. Do not apply sealer or polish. Plan for real walls and final touchups. Countertops come first. Existing walls are rarely perfectly straight, square, or plumb, so review the finished wall line with the installer. Conventional tile backsplash generally follows the countertop. A full-height slab backsplash needs its own accurate field measurements, layout, outlet details, and installation scope. Schedule paint and drywall touchups last. Even with reasonable protection, moving heavy stone can cause minor scuffs to adjacent finished surfaces. Warranty Checkpoint.

We supply the full slabs. This guide walks you through choosing a material, evaluating full slabs, the showroom visit, and comparing written quotes. See the Full Slab: Selection & Purchasing Guide Begin Here: Your Purchasing Journey Choosing a slab is the most visible decision in your project, and it deserves more than a glance at a small sample. This guide walks you through the full purchasing journey, step by step: start with the right material for your application, evaluate the full slab, inspect actual slabs at our showroom, confirm every product detail, qualify independent fabricators, compare written quotes, and move through purchase to installation with every approval in place. We are Verona Quartz Surfaces, a family owned wholesale supplier of full slabs in Sun Valley, California. We supply full slabs only. We do not fabricate, cut, template, or install. Fabrication and installation are performed by independent qualified fabricators and installers that you select, and much of this guide is devoted to helping you choose them well. This is a purchasing guide. It covers selection through purchase. For the installation phase itself, our Installation Readiness Guide goes deeper on site readiness, sequencing, and what to expect on installation day, and we link to it rather than repeat it here.

From Slab Selection To Purchase And Installation Download the See the Full Slab Guide (PDF) Start With The Material, Not The Sample Why Performance Comes Before Color Most buyers start with color and work backward. We suggest the reverse. A design you love in the wrong material for your application will disappoint you for years, while the right material in a design you chose with full information becomes the surface you stop thinking about because it simply performs. Before you fall in love with a pattern, decide which of our three materials fits how you live, where the surface will go, and what it will be asked to handle every day. Match The Material To The Application Our slabs serve a wide range of residential and light commercial applications. As you read the material profiles below, keep your own project list in front of you: Kitchen countertops and islands Waterfall edges Full height backsplashes Bathroom vanities Shower walls Fireplace surrounds Interior wall cladding Outdoor kitchens The Three Materials We Supply Engineered quartz. Our standard jumbo slab measures 126 by 64 inches at 20 mm thick, for interior use only. Quartz is a nonporous surface, and it carries a lifetime residential material warranty, subject to terms. On heat: quartz is heat resistant, not heat proof. Discoloration can occur with sustained exposure above 300 degrees Fahrenheit, so always use trivets or hot pads under hot cookware. Porcelain. Our porcelain panels measure 126 by 64 inches, at 12 mm thick. Porcelain is rated for interior and exterior use, carries a 25 year warranty, and never requires sealing. Sintered stone. Our sintered stone slabs measure 126 by 64 inches in both 12 mm and 20 mm thicknesses. Sintered stone is rated for interior and exterior use, carries a 25 year warranty, and is made with a resin free mineral body.

Large format porcelain and sintered panels call for specialized equipment and proven experience with the exact material. Confirm this during fabricator interviews in Chapter 5. Warranty Lifetime residential material warranty, subject to terms 25 year warranty; review the full warranty terms on the product page 25 year warranty; review the full warranty terms on the product page Appearance Designs range from quiet and uniform to boldly veined across all three materials. Judge each design by its full slab image, never by a small sample alone. Material warranties cover the slab material itself under their stated terms. They are not workmanship warranties. The quality of cutting, edging, seaming, and installation is covered, if at all, by your independent fabricator and installer. See Chapter 5. Your Material Decision, Step By Step List every application in your project, room by room. Mark each one indoor or outdoor. Anything outdoors or in direct sun rules out quartz, which is interior use only. Check your largest single piece against slab sizes. A 126 by 64 inch slab covers most islands; confirm with your layout. Be honest about heat habits. If hot pans meet the counter often, quartz asks you to commit to trivets every time. Decide how much maintenance thinking you want to do. Porcelain never requires sealing, which matters to some households and not at all to others. Read the warranty terms on the product page for each design you shortlist. Record your shortlist with exact product names and page URLs before moving to Chapter 2. Worksheet 1: Material Selection — Quick Check Which rooms and applications will use this surface? Will any surface be outdoors or in direct sun? Only porcelain and sintered stone are exterior rated. What is the largest single piece your layout needs, and does a 126 by 64 inch slab cover it? Do you place very hot cookware directly on the counter? Quartz is heat resistant, not heat proof, and asks for trivets every time. How important is a surface that never requires sealing? Which warranty terms matter most, and have you read them on the product page? What are the exact product names and page URLs for your shortlisted designs? Use the printable guide to record your answers and compare your selections: Download the See the Full Slab Guide (PDF) . Figure 1-1. A small sample shows a corner of the pattern. The full slab shows the whole story. (Conceptual diagram.) Evaluate The Full Slab And See How It Looks Installed What A Small Sample Cannot Show You A sample is a few inches across. A slab is more than ten feet long. No sample, however accurate its color, can show you how a pattern behaves at full scale: how large a vein grows across 126 inches, where the movement concentrates and where it rests, whether the pattern has a direction, and how much of the slab is quiet background. Choosing from a sample alone is how buyers end up surprised by a bold vein crossing their island or by a design that reads far busier installed than it did in their hand. The sample starts the conversation. The full slab image finishes it. One exception: if you are choosing a monochromatic or solid quartz, or a sparkle grained quartz with a fine, even speckle, the sample can be enough. Those colors read uniform across the slab the majority of the time, so what you hold is very close to what you get. For anything with veining or movement, the full slab image still carries the decision. Read The Full Slab Like A Professional When you open a full slab image, evaluate it the way our showroom staff does, element by element: Background tone. The dominant color of the slab body, judged in neutral light, not in your mind's memory of the sample. Undertone. The warm or cool cast sitting underneath the background tone. Undertones decide whether a slab harmonizes with your cabinets and flooring or quietly fights them. Movement. How the pattern flows across the surface: soft and cloudy, linear and directional, or dramatic and high contrast. Vein scale and distribution. Are the veins fine or bold, sparse or dense, evenly spread or clustered in zones? Note the pattern character — structured, flowing, organic, clouded, or diffused. A cluster you love on screen becomes a permanent feature on your counter. Directional patterns. Some designs have a clear direction. Direction affects how the slab can be oriented, where seams fall, and whether a waterfall edge continues the pattern convincingly. Finish. Confirm the exact finish of the SKU you are considering, and note how it reads in the image: light behaves differently on every finish. Slab to slab variation. Natural looking designs vary from slab to slab. The image shows one representative slab, not a promise that every slab looks identical. Chapter 3 covers how to handle this in person. Use Our Product Pages The Right Way On every veronaquartz.com product page, the full slab image is shown first, with real installed project photos following in that product's image gallery. Scroll or click through the gallery to see how the design reads once it is in a finished space: on a horizontal countertop under task lighting, on a vertical full height backsplash, next to real cabinetry. This is the closest you can come to seeing your project before it exists. One honest note: not every design has installed photos, but the majority of our product pages carry real installed images from our network of fabricators, contractors, dealers, and architects — essentially a collection of our clients' finished work. We do not install countertops ourselves; these photos show what our clients and their trades built with our slabs. Where a gallery exists, use it. Where it does not, the full slab image plus a showroom visit carry the decision. Upright Slab Views Versus Installed Views A slab viewed upright on an A-frame rack in a warehouse reads differently than the same slab installed. Three effects cause most of the difference: Orientation. Horizontal on a counter, the pattern spreads under your hands and your lighting. Vertical as cladding or a full height backsplash, the same pattern stacks and draws the eye upward. A directional design can look calm one way and restless the other. Distance. Stand back, literally or by zooming out. Bold veining that thrills at arm's length can dominate a room from ten feet away, and fine detail that looks plain up close can give a surface its depth from across the kitchen. Lighting. Warm under cabinet lighting, cool daylight, and dim evening light each pull different undertones out of the same slab. Compare the gallery photos taken in different light, and notice which version matches the light in your own rooms. Figure 2-1. The same veining reads differently in horizontal and vertical installations. (Conceptual diagram.) Questions To Ask Before Choosing From A Screen Have I seen the full slab image, not just the sample or a cropped detail? Have I clicked through every installed photo in the gallery, in different light and orientations? Can I describe the undertone in my own words, and does it agree with my cabinets, flooring, and paint? Where does the boldest movement sit, and am I comfortable with it landing on my island or main counter run? Does the pattern have a direction, and have I thought about how it will orient on my layout? Am I judging color on a calibrated, reasonably bright screen, not a dim phone in a dark room? Have I recorded the exact product name, SKU, and page URL so the slab I choose online is the slab I ask about in the showroom? If you cannot visit our showroom, our online samples program lets you order samples to evaluate at home. Treat the sample as a color reference only; every scale and movement judgment still belongs to the full slab image. Worksheet 2: What to Look For in the Full Slab Does the background tone look the same across the full slab as it does in the sample? Is the undertone warm, cool, or neutral, and does it agree with your cabinets and flooring? How does the movement and flow read at full scale? Are the veins fine or bold? Are the veins evenly distributed, or concentrated in certain areas? Is the pattern directional, and if so, which way does it run? What finish is listed for this SKU, and how does it read in the image? Which areas of the pattern would you want visible in your finished countertop, and which would you avoid in your layout? Use the printable guide to record your answers and compare your selections: Download the See the Full Slab Guide (PDF) . Worksheet 3: Product Gallery Checklist Open the product page through Find Your Stone . Study the full slab image first, at full size. Name the background tone and undertone in your own words. Trace the movement and mark where veins cluster. Click through every installed photo in the gallery. Compare how the design reads in different light and orientations. Confirm SKU, dimensions, thickness, finish, and warranty on the page. Save the exact product name, SKU, and page URL. Use the printable guide to record your answers and compare your selections: Download the See the Full Slab Guide (PDF) . Inspect The Actual Slab At The Showroom Photography gets you most of the way. Standing in front of the actual slab gets you the rest. Scale, true color, and the way light moves across a full surface cannot be fully rendered on a screen, and a showroom visit is where you confirm that the design you chose online is the design you want in your home. To schedule a visit, reach us through our Contact page. Prepare For The Visit An hour of preparation makes the visit twice as productive. Bring: Cabinet door, paint chip, and flooring samples, the real materials, not phone photos of them Approximate dimensions of your countertops, island, backsplash, or other applications A list of your planned applications, room by room Your saved product names, SKUs, and page URLs from Chapter 2 This guide, with your worksheets filled in so far Look From A Distance, Then Up Close Start ten or more feet back. This is how the slab will read when you walk into the room, and it is the view photography flattens. Notice the overall impression before you notice the detail: calm or energetic, light or grounded, warm or cool. Then move in close and confirm the particulars: the undertone against your cabinet sample, the crispness of the veining, the finish. Hold your cabinet and flooring samples directly against the slab, not a foot away from it. Adjacent comparison is the only comparison that counts. Figure 3-2. Compare the slab's undertone against your cabinets, flooring, and hardware. (Conceptual diagram.) Ask To See Slabs In Natural Daylight Warehouse lighting is consistent, which is useful, and it is also incomplete. Ask our staff whether you can view your shortlisted slabs in natural daylight, not only under warehouse lighting. Undertones shift between the two, and since your kitchen lives in daylight for much of the day, you want to approve the slab in the light it will actually live in. Figure 3-1. Undertone and movement read differently in warehouse light and natural daylight. (Conceptual diagram.) Compare Slabs, Batches, And Book Matched Pairs Ask to see more than one slab of your chosen design. Compare vein distribution, scale, and background tone across them so you understand the natural range of the design. If your project calls for it, ask about book matching: two consecutive slabs whose veining mirrors along a shared edge, opening like the pages of a book. When book matching matters to your layout, ask to examine the actual pair together, in sequence, exactly as they would be placed. Do not approve a book matched pair from descriptions or from photos of different slabs. Figure 3-3. A book matched pair mirrors veining across the seam. Examine the actual pair. (Conceptual diagram.) Let Staff Handle The Slabs Slabs are heavy, fragile at the edges, and stored on A-frame racking systems that require training to work around. Our staff will pull, position, and return every slab you view. Buyers never move slabs themselves and never enter restricted storage or handling areas. This is for your safety and for the protection of the material. Take Home Samples If you want to live with a color reference at home, you may ask our staff about available small take-home samples, subject to availability and current policy. Remember what a sample is: a color and undertone reference for comparing against your cabinets and flooring in your own light. It is not a substitute for the full slab judgments in Worksheet 2. Worksheet 4: Showroom Visit and Full Slab Observations Before and During Your Showroom Visit Brought cabinet, paint, and flooring samples Brought approximate dimensions and application list Brought saved product names, SKUs, and page URLs Viewed shortlisted slabs from ten or more feet back Compared slabs up close against cabinet and flooring samples Viewed slabs in natural daylight, not only warehouse lighting Compared at least two slabs of the chosen design for variation If book matching: examined the actual pair together, in sequence Asked staff about available take-home samples Recorded exact slab numbers of the slabs viewed Compare the Slabs You Viewed For each slab you seriously consider, note the following: Slab number Background tone in daylight Undertone against my cabinet sample Vein scale and distribution Directional pattern and orientation Finish, confirmed for this SKU Visual condition notes Overall preference ranking Use the printable guide to record your answers and compare your selections: Download the See the Full Slab Guide (PDF) . Questions To Confirm Before Choosing Or Buying Slabs Once you have a chosen design, slow down and confirm the commercial details before money changes hands. Slabs are a significant purchase, and most expensive misunderstandings come from details that were assumed rather than recorded. Ask every question below, and write down every answer in Worksheet 5. Record The Exact Product Details Exact product name and SKU Material: engineered quartz, porcelain, or sintered stone Slab dimensions and thickness Finish, exactly as listed for the SKU Available quantity of that design Batch or lot number of the slabs you viewed Which specific slab numbers you viewed Book matching status: is the pair you examined reserved together Visual condition of the specific slabs, noted while you look at them Current availability and whether more slabs of the same batch can be obtained Hold or reservation policy: how long a slab can be held, and under what terms Delivery or pickup expectations Lead time from purchase to availability for your fabricator Warranty terms for the material, and where to find them in writing Tag The Slab And Photograph The Slab Number The slab you pick should be the slab you receive. When you select specific slabs, confirm they are tagged or otherwise identified as yours, and photograph each slab number yourself. Keep those photos with your Slab Selection Record. If slabs are ever substituted, you will know, and you will have the record to resolve it. Your Dimensions Are Approximate Until Your Fabricator Approves Yield The dimensions you bring to the showroom are approximate countertop dimensions. They are not a slab order. Only your independent fabricator, working from a template of your actual cabinets — either a physical template or professional digital (laser) templating — determines final quantities and whether your layout is feasible from the slabs you selected. Never let an approximate measurement lock you into a slab count. Chapter 5 explains how to get your fabricator involved at the right moment, before purchase commitments become expensive. Think Through Layout Before You Buy You do not need a final shop drawing at the selection stage, but you do need to think through the layout questions that affect how many slabs you need and which ones: Orientation. Which direction will the pattern run on each piece, especially for directional designs Seams. Where seams will likely fall on long runs, and whether you accept their placement Waterfall continuity. Whether the pattern continues convincingly from the top over the waterfall edge, and which slab area provides that continuity Sink and cooktop positions. Their approximate locations, since cutouts consume material and constrain layout Cutout geometry. Undermount, apron, or drop in sinks and their rough sizes, because cutout placement affects yield Waste and contingency. Layouts produce offcuts. Discuss with your fabricator how much extra material your layout realistically requires rather than assuming a formula. Figure 4-1. Conceptual cut layout. Your independent fabricator determines final slab yield. (Conceptual diagram.) Worksheet 5: Details to Confirm Before Purchasing Product identification Exact product name SKU Material Slab dimensions Thickness Finish Actual slab identification Slab numbers viewed Batch or lot number Book matched pair identified (slab numbers) Visual condition notes Availability and reservation Quantity available Hold or reservation terms Logistics Delivery or pickup expectations Lead time Documentation Warranty terms acknowledged (where documented) Staff member spoken with Date Use the printable guide to record your answers and compare your selections: Download the See the Full Slab Guide (PDF) . Qualify Three Or More Independent Fabricators The slab is the material. The fabricator is the craft. Cutting, edging, polishing, seaming, templating, and installation determine how your project looks and how long it lasts, and the difference between a careful fabricator and a careless one is visible every day for decades. This chapter is the longest in the guide because this decision carries the most weight. Why Three Or More One conversation gives you a sales pitch. Two give you a comparison. Three or more give you a market: you will hear how different shops handle your material, what each includes and excludes, how each communicates, and what each charges for the same scope. The time you spend here is repaid in fewer surprises and a measurably better result. Gather names from our Dealer Locator , from your contractor or designer, and from homeowners whose finished work you can see in person. Fabricators and installers are independent professionals. They are not Verona staff, and we do not direct their work. We supply full slabs only. We do not fabricate, cut, template, or install. Your contract for fabrication and installation is with the fabricator you choose, and your evaluation of that fabricator is your protection. Qualify Beyond Reviews And Price Online reviews and the bottom line price are starting points, not qualifications. Evaluate each candidate on: Experience with your exact material. Quartz, porcelain, and sintered stone behave differently under the saw. Ask how many projects they have completed in your specific material in the past year. Comparable portfolio. Ask to see finished work in your material, at your scale: islands, waterfall edges, full height backsplashes, and shower walls comparable to yours, not just small vanities. Location and service area. Confirm they serve your address, and understand how distance affects templating visits, delivery, and any return trips. Contractor license where required. Ask for the license number and verify it with the issuing authority where your state or locality requires one. Insurance. Ask for proof of general liability coverage, and workers compensation where applicable. This protects your home and everyone in it. References. Ask for recent clients with projects like yours, and actually call them. Ask what went wrong and how the shop handled it. Communication. Note how promptly and clearly they answer during quoting. Quoting behavior predicts project behavior. Written agreements. Insist on written scope, schedule, and terms before any deposit. Verbal promises are not a contract. Personnel. Ask who will template, who will fabricate, and who will install. The person you meet may not be the person who does the work. Aftercare. Ask what happens if a seam opens, a chip appears, or you have a question six months later. Workmanship warranty. Ask what they warrant, for how long, and in writing. This is separate from our material warranty. Guarantee on porcelain and sintered stone. Ask whether the fabricator guarantees their work on porcelain and sintered stone specifically. If a slab is damaged at their shop or during transport, who assumes liability? Choose fabricators and installers who back their process and guarantee their work. Visit The Fabrication Shop We encourage you to request a scheduled, supervised visit to the actual fabrication shop of any finalist. A fabrication shop is an operating industrial facility: saws running, slabs racked, dust controlled, crews at work. It is not a sales showroom, and the visit serves a different purpose than a showroom visit. In a sales showroom you evaluate designs. In a fabrication shop you evaluate competence: how slabs are stored and handled, how clean and organized the floor is, what equipment is in use, and how the staff talks about your material. Schedule the visit in advance, follow the shop's safety instructions exactly, stay with your escort, and never enter active cutting areas or approach operating equipment. You are there to observe and ask questions, not to inspect the facility yourself. Figure 5-1. What to observe on a scheduled, supervised fabrication shop visit. Questions To Ask In The Shop Slab handling and storage. How are slabs received, stored, and moved? How do you protect edges and faces during handling? Layout review. Will you review my slab selection against my layout before cutting, and will I approve the layout drawing showing seam locations and pattern placement? Equipment. Do you cut with a bridge saw, CNC, waterjet, or a combination? Which do you use for my material, and why? Edge finishing. Which edge profiles do you offer in my material and thickness, and can I see and feel finished samples? Sink and cooktop support. How do you support undermount sinks and cooktop cutouts? What reinforcement do you use, and where? Seam methodology. Where do you place seams as a rule, how do you join them, and what should I expect a seam to look like in my design? Large format competency. For porcelain and sintered panels, what specific equipment and experience do you have with large format material? Can I see a completed large format installation? Quality control. What do you check before a piece leaves the shop, and what do you check on site before installation begins? Protective transport. How are finished pieces protected and braced during transport to my home? Installation sequencing. Walk me through installation day: crew size, hours, what you need from me, and how the pieces are set, leveled, and seamed on site. Ask About Silica Safety Cutting and polishing engineered stone, granite, quartzite, and other silica containing materials can generate respirable crystalline silica dust, which is a serious and well documented health hazard when inhaled over time. This is primarily a worker safety matter, and it is also a useful window into how a shop is run. Ask each fabricator about their safety policies and documented OSHA compliance for silica exposure, including dust control and housekeeping practices. We recommend working with fabricators who follow OSHA wet cutting and polishing methods, which suppress dust at the source. Do not enter active cutting areas during your visit, and do not attempt to conduct your own safety inspection of a shop. Ask about policies, listen to the answers, and weigh them alongside everything else. For background on the hazard itself, see the OSHA and NIOSH resources listed in our Sources section. Red Flags No interest in which exact material you selected, or vague answers about material specific experience Reluctance to show a portfolio of comparable finished work No contractor license where one is required, or no proof of insurance Refusal to provide references, or references that cannot be reached Unwillingness to schedule a supervised shop visit Dismissive or evasive answers about dust control and safety policies Quotes given only verbally, or pressure to sign and deposit immediately A price dramatically below the others with no clear explanation of what is excluded No written workmanship warranty, or a warranty with no stated duration Worksheet 6: Questions to Ask Before Hiring a Fabricator Work through the questions below with each candidate during or immediately after each interview. What is the company name and contact, and does it serve my address? How many projects has it completed in my exact material in the past year, and have I reviewed comparable completed work? Is its contractor license (where required) verified, is insurance documented, and have I contacted references? Have I completed a supervised shop visit, and what did I observe? What cutting equipment does it use for my material — bridge saw, CNC, waterjet, or a combination — and what large-format porcelain or sintered experience does it have, if applicable? How does it explain seam placement and finishing, and sink and cooktop support and reinforcement? What are its silica safety policies, and does it follow OSHA wet cutting and polishing methods? Has it offered a written scope, schedule, and terms, with workmanship warranty terms in writing? How well does it communicate, and what is my overall impression and ranking? Use the printable guide to record your answers and compare your selections: Download the See the Full Slab Guide (PDF) . Compare Three Written Fabrication Quotes With qualified fabricators identified, the next step is documented, comparable pricing. Collect written quotes from at least three of them, built on the same scope, and compare them line by line. This chapter shows you what each quote must contain and how to read what is missing. Raw Slab Price Is Not The Project Cost The price of the slab and the price of the finished project are different numbers, and confusing them is one of the most common budgeting mistakes in this process. The slab is material. The project is material plus templating, fabrication, edging, cutouts, reinforcement, seaming, delivery, installation, removal of existing surfaces, plumbing coordination, taxes, and everything else your home requires. Compare installed project costs, not slab prices, and make sure every quote prices the same scope before you compare the totals. Every Quote Should Document These Fields Material: exact product name, SKU, quantity of slabs, and who supplies the slabs Layout: seam locations shown on a drawing, or a commitment to provide one for approval Dimensions: which measurements the quote is based on, and whether templating is included or separate Edge profile: the exact profile name and which edges receive it Waterfall edges and full height backsplashes: priced as separate line items with their material included Cutouts: each sink, cooktop, and fixture cutout listed individually Sink support: the reinforcement method for undermount sinks, stated explicitly Templating: included, with the number of site visits stated Corners and reinforcement: inside corners, narrow strips, and any required reinforcement Removal and disposal: of existing countertops, if applicable Delivery: transport of finished pieces to your home, with protection described Installation: setting, leveling, seaming, and cleanup on site Taxes, travel charges, and permit costs where applicable Lead times: templating to fabrication, fabrication to installation Deposit terms: amount, timing, and refund conditions Change policy: how changes after approval are priced Exclusions: everything not included, listed explicitly rather than left unsaid Damage responsibility: who bears the cost if a piece breaks during fabrication, transport, or installation Warranties: workmanship warranty terms in writing, separate from our material warranty How A Lower Quote Can Omit Costly Items A quote that comes in well below the others is not necessarily a bargain. It is often a narrower scope. Common omissions that turn a low quote expensive later include: Templating billed separately after you have committed Cutouts priced per opening, with only one or two included in the base price Sink reinforcement or support hardware excluded Waterfall edges or full height backsplashes quoted without their material Removal and disposal of existing tops left out Seams placed for the shop's convenience rather than your approval, with no layout drawing Delivery beyond a limited radius charged extra No written workmanship warranty, which has a real value you will miss only when you need it A miscalculated or missed slab count. If the fabricator only realizes they need extra material after cutting has started, the price can change drastically. That is why it pays to use this guide and triple-check your slab count before locking in a fabricator price. None of these omissions is automatically improper. What matters is that you see them before you choose, not after the deposit is paid. Mark Every Line Included, Excluded, Or Clarify Use Worksheet 7 to compare your three quotes side by side. For every line item, mark each quote as Included, Excluded, or Clarify, and write the quoted figure or term beside it. Any row where the three quotes do not match is a question to take back to the fabricators before you decide. Apples to apples is not a figure of speech here; it is the entire method. Figure 6-1. Compare quotes by inclusion, exclusion, and items to clarify — not by the bottom line alone. Worksheet 7: What to Compare in Every Fabrication Quote For each line item, mark every quote Included, Excluded, or Clarify, and note the figure or term. Material selection, slab quantity, and who supplies the slabs Exact product name, SKU, and slab quantity Who supplies the slabs Layout drawings, templating, seam locations, and final dimensions Layout drawing with seam locations Templating, including number of site visits Edge profiles, waterfall details, and full height backsplashes Edge profile, by name, on which edges Waterfall edges, material included Full height backsplash, material included Sink, cooktop, and other cutouts, including reinforcement and support Sink cutouts, each listed Cooktop and fixture cutouts, each listed Undermount sink support and reinforcement Inside corners and narrow strip reinforcement Removal, disposal, delivery, installation, and cleanup Removal and disposal of existing tops Delivery with protection described Installation: setting, leveling, seaming, cleanup Taxes, permits, travel charges, and scheduling Taxes, travel, and permit costs Lead times, templating to installation Deposits, changes, exclusions, and damage responsibility Deposit amount, timing, and refund conditions Change policy after approval Exclusions listed explicitly Damage responsibility during fabrication, transport, installation Warranty terms and the total installed project cost Workmanship warranty in writing Total installed project cost, same scope The complete comparison worksheet is available in the downloadable PDF: Download the See the Full Slab Guide (PDF) . From Slab Selection To Purchase And Installation You have chosen the material, evaluated the full slab, inspected actual slabs, confirmed the product details, qualified fabricators, and compared written quotes. This final chapter puts those decisions in their responsible order, assigns each job to its owner, and gives you the last checklist before anyone cuts stone. The Responsible Sequence Choose the design. Material first, then the full slab image and gallery, then the showroom visit. Record the slabs. Complete your Slab Selection Record with exact slab numbers, batch, and hold terms. Consult your fabricator. Bring your selection and approximate dimensions to your chosen fabricator before final purchase commitments, so yield and feasibility are confirmed by the people doing the work. Confirm cabinet and site readiness. Cabinets set, level, and secured; the site prepared per your fabricator's requirements. Templating. Your fabricator templates the actual installed cabinets — either with a physical template or with professional digital (laser) templating. Nothing is cut from approximate dimensions. Layout approval. You approve the layout drawing: seam locations, pattern placement and orientation, waterfall continuity, and every cutout position. Pickup or delivery of slabs. Your purchased slabs move to the fabricator under agreed terms. Fabrication. Cutting, edging, polishing, and quality control at the shop. Installation. Setting, leveling, and seaming on site. Final inspection. You walk the finished work against your approved layout and quote before final payment.

For the installation phase itself, including site readiness, sequencing, and what to expect on installation day, our Installation Readiness Guide covers it in full. We keep the detail there so each guide does one job well. Worksheet 8: Final Project Approval Checklist Complete the pre purchase section before slabs are purchased, and the layout approval section before any slab is cut. Before Purchasing Slabs Slab numbers match my Slab Selection Record Batch or lot confirmed for all slabs Book matched pair reserved together, if applicable Hold or reservation terms understood Fabricator has reviewed my selection against my layout Slab quantity confirmed by the fabricator, not by my estimate Written fabrication quote signed, scope complete Deposit terms and refund conditions understood Delivery or pickup date for slabs agreed Before Fabrication Begins Cabinets set, level, and secured Templating completed from actual cabinets Layout drawing approved: seam locations Layout drawing approved: pattern placement and orientation Layout drawing approved: waterfall continuity Layout drawing approved: every cutout position Edge profile confirmed by name Sink and cooktop models confirmed with the fabricator Installation date scheduled Workmanship warranty received in writing Material warranty terms on file Use the printable guide to record your answers and compare your selections: Download the See the Full Slab Guide (PDF) .

Frequently Asked Questions Why Should I View The Full Slab Instead Of Choosing From A Sample? A sample shows you color. Only the full slab shows you scale: how large the veins grow, where movement clusters, whether the pattern has a direction, and how much of the surface is quiet background. Chapter 2 explains how to read a full slab image element by element. Where Do I Find Installed Examples On A Verona Product Page? On every veronaquartz.com product page, the full slab image is shown first, and real installed project photos follow in that product's image gallery. Scroll or click through the gallery to see the design in finished spaces. Galleries vary by product, and not every design has installed photos. What Are The Limits Of A Small Sample? A sample is a reliable color and undertone reference for comparing against your cabinets and flooring in your own light. It cannot show vein scale, distribution, movement, or directional pattern at full size. Never approve scale or movement from a sample. How Do Undertones And Lighting Affect What I See? Undertones decide whether a slab harmonizes with your room or fights it, and lighting changes which undertone you perceive. View slabs in natural daylight as well as warehouse lighting, hold your real cabinet and flooring samples directly against the slab, and compare gallery photos taken in different light. What Is Book Matching And Should I Ask For It? Book matching pairs two consecutive slabs so the veining mirrors along a shared edge, opening like the pages of a book. It suits symmetrical feature areas such as waterfall islands and full height backsplashes. If it matters to your layout, examine the actual pair together, in sequence, before approving. Why Do Slabs Of The Same Design Look Different From Each Other? Natural looking designs vary from slab to slab in vein distribution, scale, and background tone. Compare at least two slabs of your chosen design, note the batch or lot number, and select and photograph your exact slab numbers so the slab you pick is the slab you receive. How Do I Choose A Fabricator? Get information from at least three independent fabricators and qualify them on experience with your exact material, a comparable portfolio, license where required, insurance, references, communication, written agreements, aftercare, and a written workmanship warranty. Chapter 5 gives the full method. Why Does A Shop Visit Matter? A scheduled, supervised visit to the operating fabrication shop shows you how slabs are stored and handled, what equipment is used, how the floor is run, and how the staff talks about your material. A sales showroom shows you designs; a fabrication shop shows you competence. Stay with your escort and never enter active cutting areas. What Should A Fabrication Quote Include, And What Do Exclusions Mean? A complete quote documents material, layout and seams, templating, edge profile, waterfall and backsplash work, every cutout, sink support, removal and disposal, delivery, installation, taxes and fees, lead times, deposit terms, change policy, damage responsibility, warranties, and explicit exclusions. A lower total often reflects a narrower scope, so compare line by line using Worksheet 7 before comparing totals. Who Is Responsible For Seams And Cutouts? Your independent fabricator and installer: seam placement and execution, sink and cooktop cutouts, and their support and reinforcement are fabrication work. You approve the layout drawing showing seam locations and every cutout position before any slab is cut. How Many Slabs Will My Project Need? Your approximate dimensions produce an estimate, not an order. Only your fabricator, working from a template of your actual cabinets — either a physical template or professional digital (laser) templating — and an approved layout, determines final slab quantities and feasibility. Confirm yield with your fabricator before final purchase commitments. What Is The Difference Between A Material Warranty And A Workmanship Warranty? Our material warranty covers the slab material itself under its stated terms: lifetime residential for quartz, 25 years for porcelain and sintered stone. It does not cover cutting, edging, seaming, or installation. Those are covered, if at all, by your fabricator's separate written workmanship warranty. Does Verona Install Countertops? No. We supply full slabs only. We do not fabricate, cut, template, or install. Fabrication and installation are performed by independent qualified fabricators and installers that you select. What Must Be Approved Before Any Slab Is Cut? The layout drawing showing seam locations, pattern placement and orientation, waterfall continuity, and every cutout position; the edge profile by name; the sink and cooktop models; and the signed written quote. Worksheet 8 collects every approval in one place. Sources The guidance in this guide rests on the following official sources. Consult them directly for the full text behind any summary here.
