How to build a plumbing access panel backside of shower?
I will have plumbing in a wall that could be made accessible from the other side. A cabinet will be mounted on this other side. I would like to make this so the plumber can access the rough-in shower stuff, in the future, if need be. The shower will be tiled and I don't want to mess with the tiled side of the wall. How is this done? Do I have the cabinet side cut out? Do I have the carpenter frame up an access area then drywall, leaving the opening open, mounting the cabinet, covering the hole? Do I have a door put on the opening, like a secret compartment, then mount a cabinet without a side onto the wall?
What are the thoughts on this? What have others done?
