I just saw photos of a DIY shower that was lined on the inside with sheet aluminum. The aluminum appeared to be screwed to the wall using exposed metal roofing screws (the kind with rubber washers), and it met a tiled floor/curb at the bottom. I loved the look and would like to build it into our current bathroom new construction project. Currently, I have drywalled the area (the structure is a stud wall with Icynene SPF insulation) with mold-tough drywall, and had planned to use kerdi membrane before adding tile on the walls and floor. If I was to use the sheet metal on the walls instead, what would be the appropriate backing and waterproofing behind it? And how to finish the bottom, where the metal would meet the curb…?
On an outside corner formed by a double layer of drywall, the corner bead can be fastened without nails or screws.
