OK so I know this stuff exists, but I cannot seem to find a supplier of it anywhere! I am looking for shower wall paneling that looks just like granite/marble...but its not. Its actually a plastic type of material. I've seen floor demo shower and baths set up like this at local hardwares, so I know that it exists. The hardwares don't carry it though...when I asked I was told it is only available when I hire them to do a remodel. Well, I don't want to hire someone else, I want to do it myself. So where can I find a supplier of this type of product that will sell to the individual? And why is it so hard to find, anyway? I don't know what it costs, but I can only assume it is hundreds (probably thousands) less than paneling your entire shower wall with real granite or marble... Thanks!!
