Secolo Porcelain Slabs from Walker Zanger offer the look and feel of real marble, cement, and wood, but with the durability of porcelain. At 12 mm, the slabs are thicker than most porcelain products, which range from 3 mm to 6 mm. The thickness allows a full slab, at 126 by 63 inches, to be used as a countertop. Slabs are nonporous and resistant to stains, including those from acidic liquids such as red wine. They come in 12 colorways, all with a polished finish. walkerzanger.com
