Porcelain tiles are ceramic tiles commonly used to cover floors and walls, with a water absorption rate of less than 0.5 percent. The clay used to build porcelain tiles is generally denser. They can either be glazed or unglazed. Some homes have used large-format tiles to replace smaller tiles as a sink backsplash. Large-format tiles also make excellent flooring for the area around the bathroom fixtures. Thus, they also make excellent laundry room floors. These tiles have fewer joints to absorb water, collect grime, or grow mold.
