Is porcelain tile waterproof?
Porcelain tiles are water-resistant and can be a great choice for bathrooms, basements, laundry rooms or any place that might become damp. They are even more liquid-resistant than ceramic tile.
But, if the water sits on porcelain tiles for long enough, it can seep into the tile and create mold or moisture problems. As long as you clean up your spills in a reasonable amount of time, porcelain tiles will last for years without water damage.
