I have a large room with water and drain access and am wanting ot put in a non-permanent shower. I have sourced a shower enclosure and base, as well as a pump for the drain water to pump it up and out through a drain. But in remodeling the room and getting it ready to do this I would like to make sure I do everything correctly.
My question is what to use for the walls? When I leave this place I will be removing the shower enclosure and will leave the walls in place. Do I use regular greenboard? Or would it make more sense to use hardie backer for the walls in the corner where the shower will go?
