Where to Buy Large-Format Porcelain Slabs in the Bay Area (and What to Check First)

Shopping for large-format porcelain or sintered-stone slabs in the Bay Area? Where they are sold, which thickness suits counters versus walls, and what to confirm with the seller and your fabricator.

October 4, 20267 min read

Large-format porcelain and sintered-stone slabs are sold in the Bay Area by stone and slab yards, tile showrooms, countertop fabricators and online suppliers that deliver locally. Surface Surgeon, the surfaces department of RemodelER, is one of the online options: it lists porcelain slabs alongside Dekton and Neolith and delivers across the San Francisco Bay Area, to your driveway or straight to your fabricator. Before you buy from anyone, check five things: the slab thickness against how you will use it, the exact slab size, whether the pattern runs through the body, whether multiple slabs come from the same production lot, and whether your fabricator has worked with porcelain before. The last one matters most, because porcelain is cut and handled differently from quartz or granite.

What counts as a large-format porcelain slab?

A porcelain slab is a single fired sheet of porcelain made at countertop scale, commonly around 10.5 feet by 5 feet (roughly 320 by 160 centimeters), where a floor tile is measured in inches. Sintered stone and ultracompact surfaces, such as Neolith and Dekton, are made by a related high-heat, high-pressure process and are shopped, cut and installed in much the same way, so most people compare them together.

These slabs are non-porous, do not need sealing, tolerate heat well and hold their color in sunlight, which is why they are used outdoors and on fireplace surrounds as well as on kitchen counters. Our porcelain slab countertop guide covers how they compare to quartz and natural stone day to day.

Where can you buy porcelain slabs in the Bay Area?

  • Stone and slab yards. You can walk the inventory and see full slabs. Pricing is usually given at the desk rather than posted.
  • Tile and surface showrooms. Good for comparing finishes and thin panels for walls. Slabs are often ordered in rather than held on site.
  • Countertop fabricators. Many supply the slab as part of an installed price, which is convenient but blends material and labor into one number.
  • Online suppliers with local delivery. The catalog and prices are published, and the slab is delivered to you or your fabricator. This is how Surface Surgeon works.

Which thickness do you need?

Thickness is the first thing to get right, because the same color is often made in several. Thin sheets, around 6 millimeters, are made for wall cladding, shower walls, backsplashes and furniture fronts. Countertops are normally made from 12 millimeter or 20 millimeter material (1.2 cm or 2 cm). A price or a photo means little until you know which thickness it refers to, so always compare like with like. On our product pages, where a slab is offered in more than one thickness, you choose the thickness per item and the price is shown for that thickness.

What should you check before you buy?

ThicknessThin cladding sheets are not countertop materialConfirm the thickness in millimeters on the quote, not just the color name
Exact slab sizeSize decides how many slabs the job needs and where seams fallGet length and width in writing and give them to your fabricator
Pattern through the bodyOn most porcelain the veining is on the surface only, which affects edges and cutoutsAsk whether the design is through-body, and how the edge will be finished
FinishPolished, matte and textured versions of one color look and clean differentlyView the finish you are actually ordering, at as large a size as possible
Same production lotShade can vary slightly between production runsFor multi-slab jobs, ask that all slabs come from one lot
BookmatchingMirrored veining needs slabs made as a matching pairAsk whether the color is produced in bookmatched pairs
Fabricator experiencePorcelain needs its own blades, cutting sequence and handlingAsk your fabricator how many porcelain jobs they have done, before you buy
DeliverySlabs travel upright on a frame and need equipment to unloadConfirm who delivers, to where, and who unloads

Why does the fabricator matter so much with porcelain?

Porcelain and sintered slabs are extremely hard and are made under tension. A fabricator who treats them like granite risks cracking the slab on the saw or at a cutout. Experienced shops use blades made for the material, make relief cuts in a set order, round the inside corners of sink and cooktop cutouts, and support the slab fully during transport and installation.

Because the pattern on most porcelain is printed on the surface, edges are usually mitered so the face design wraps down the front. That is skilled work, and it is worth asking to see a finished mitered edge your fabricator has made. Line up the fabricator first, then buy the slab to the sizes and thickness they confirm.

How does buying from Surface Surgeon work?

Surface Surgeon sells countertop slabs in quartz, porcelain, Dekton and natural stone, along with tile, mosaics and flooring. You can browse porcelain slabs, or go straight to Dekton and Neolith. We operate online, so each product page carries the photos and specifications.

Prices shown on the site are MSRP. Add the slabs to your project and send a quote request, and we reply with your actual project price, which is below MSRP. If you find the identical slab (same brand, color, thickness and slab size) advertised for less by a Bay Area supplier or online retailer, bring us the price and we will match it. Slabs are delivered across the Bay Area; our slabs by city pages cover the details for each area. The same quote can include tile, flooring, cabinets and plumbing fixtures.

Frequently asked questions

Is porcelain slab the same thing as Dekton or Neolith?

Not exactly. Dekton and Neolith are brand names for ultracompact and sintered-stone surfaces, which are made from a blend of minerals under very high heat and pressure. They behave much like porcelain slabs in a kitchen and are fabricated in a similar way, so they are usually compared side by side, but they are distinct products with their own specifications.

Can a porcelain slab be used outdoors?

Generally yes. Porcelain and sintered slabs are non-porous and color-stable in sunlight, which makes them a common choice for outdoor kitchens. Confirm the outdoor rating and the recommended thickness for your specific product with its manufacturer's documentation.

Does Surface Surgeon sell slabs to homeowners?

Yes. Homeowners can browse, add slabs to a project and request a quote without an account, and have the slab delivered to their fabricator. Contractors, designers and other trade professionals can apply for a free trade account.
