Porcelain Countertops in Tampa Bay and Southwest Florida

Where porcelain earns its place

Porcelain suits cooks who set hot pans down and owners who want few care steps. Consumer Reports’ guidance on porcelain tile says it handles heat near the stove and resists scratches, etching and food stains, and its sealing advice is about the grout, not the porcelain. A slab countertop has far fewer joints than tile. The stain it singles out is ink, which can be permanent. Extra-large slabs of 72.5 by 130 inches are also on the market, which can mean fewer seams on a long run.

The trade-offs

The trade-offs sit in the edges and the fabrication, not in daily use. Stone World’s fabrication guidance says slabs thinner than 12 mm need an internal structure such as a foam core, and one fabricator it interviewed almost always miters the edge to build a thicker profile. Sink cutouts need relief cuts and solid support, per Stone World’s fabrication guidance, and the top needs level, well-supported cabinetry. Fabricators list chipping, cracking when procedure slips, hard cutting and delicate handling as common challenges, so ask about experience with porcelain. In Consumer Reports’ impact tests on 2 cm samples of a related ultracompact material, edges chipped and cracked, so edge design deserves attention.

What to ask a fabricator

Ask who has cut porcelain before, and look at the edge on a sample.

1. The slab’s thickness, and whether the manufacturer lists it for countertop use. Per the TCNA listing, ANSI A137.3 has countertop strength criteria for three thickness classes: 3.5 to 4.9 mm, 5.0 to 6.5 mm and 20 mm and up.
2. How the edge is built, mitered or built up, and how the joint looks up close, because adhesive cannot be color-matched to hide it.
3. How cutouts will be supported, and whether the cabinet base is level.
4. How the slab is cut and finished. Porcelain is not automatically silica-free, so ask for the SDS.
