Is ceramic tile waterproof?
Ceramic tiles are not fully waterproof. Although the tiles are a popular choice for bathrooms, they are slightly porous. This means that when water splashes onto the tiles, it will remain there in a puddle on the surface until you wipe it up.
As long as you clean the tiles quickly, no water damage will occur. However, if the water is left for too long on the surface, a small amount of damage may occur.
