The overview says waterproof and can be used in a shower. The specs say, no bathroom, no shower??? I am wanting to use as a wall in shower.

Thank you for your interest in our Palisade tile samples! Our samples are a cut piece of a full tile, so they are not meant to be utilized for a project application, thus you will see in the spec and data different information than is found on our actual product specifications. Our full-size Palisade tiles are suitable for any bathroom and shower application. If you have any additional questions please feel free to reach out to us at 800.434.3750. Thank you!
