The waterproof or water-resistant feature is vital for tiles that are applied outside or inside in a wet environment, such as the bathroom. Waterproof tile can withstand larger messes, while water-resistant tile is best for small spills that will need to be cleaned up quickly. Most porcelain tiles are considered waterproof, and ceramic tiles are usually rated as water-resistant. Within Corso Italia Ceramic Tile, we carry 5 water resistant options.
