Why can't this be used on the floor?

Thank you for your interest in our Palisade Carrara Marble tiles! We do not recommend using our tiles on a working surface, such as a floor or countertop, as the tiles are not manufactured with a strong enough wear layer for that type of application. However, the tiles can be used for any wall applications, such as shower or backsplash installations. If you have any additional questions please feel free to reach out to us at 800.434.3750. Thank you!
