Are they ceramic tile or plastic panels currently?
Do you want to “cover” them for aesthetics or function?
Are you wanting to redo the walls? If so, I highly recommend subway tile. We redid our shower to subway tile, and it is fantastic and easy to maintain. I am not sure if that is what you are looking for
Need more information please.
If you could give us more information that would be great!
I’ve seen some kits with ready made tile panels that can go over an existing shower wall, otherwise it’s unclear what you’re seeking.
