I am rebuilding a bathroom with shower stall and I'm a bit unsure of the steps to complete, in which order. The shower stall is a corner unit with glass walls and door, and I intend to greenboard the walls and put down vinyl flooring.
The instructions that came with the shower aren't clear - should I put down the vinyl before the shower pan, or the other way around? If it's shower before vinyl, can the shower rest on the subfloor, or should it sit on the 1/4" plywood underlay that I will be putting down. It's a simple rectangular room with basic bathroom floor cut-outs in the vinyl. Further, does the greenboard behind the shower have to be mudded/taped and painted before I install the shower walls?
Usually the floor is butted up to the tub or shower and the interface is sealed so water can't get in.
But there's no reason you can't run it under the base. You just need to support the base evenly all around.
