Bathroom tear out and remodel with a lifetime warrantied schulter system. The original shower was leaking from a faulty install. Some issues found during tear out. The mud bed was sloped away from the drain. There was no waterproofing installed on the walls at all. the installer used 1/4 inch backer board which should be used only over top of subfloor and it was not adequately nailed, I only use screws to install backer. Some fasteners on this backer were 24 inches apart. I reused the original glass from the faulty install.
