Experts do not recommend it. Although you may apply a sealant while installing the tiles on your bathroom floors, but showers will be too risky. It is because marble is extremely porous and absorbs water at the slightest go. Better use some alternatives for your shower walls and floors. The fact is that different kinds of stone, glass, ceramic, and porcelain tile are all utilized in bathrooms and showers; there is no such thing as “shower tile.” Some of the products belonging to these materials can be used in showers, some can not. Still, the majority consider porcelain tiles the best option for showers. The short answer is yes if you’re wondering whether to use porcelain tile in your shower. However, you should check the product description very carefully when you decide.
