Not sure this necessarily falls under the "plumbing" category, but I'm getting ready to tile up a shower wall and looking for tips on the type that can be used on a shower wall. Let me preface that by saying this is a tear out of an old shower/tub combo, I've replaced with a jacuzzi (enclave style) tub, cement board above tub and now getting ready to tile walls above tub. I know there are glazed "wall" tiles specific for shower walls but I'm not crazy about the selection I'm finding with these tiles. What other options are there, can a more porous tile be used and then sealed, etc.?
