Although the wet room apparently provides benefits, there are several disadvantages. For instance, some designated areas that aren’t covered could still get wet or humid. Also, when the water can’t immerse in the floor or wall and you don’t have time to dry them up immediately, the interface could get slippery. You have to take note of these as well.  To ease this problem, you’d better get the right tiles for this purpose, such as granite, marble, or river rocks. As much as possible, you have to refrain from using ceramic tiles.
