I live in milpitas california, I am stuck in my project of remodeling my shower, one contractor sugested to install a 4mil layer of plastic, then backer board and then the tile fot the walls, but the guy who did the plumbing told me that I have to take out the plastic becouse it codenses the air humidity and I could have a problem inside the wall, so I want to know:
1.- can I live the plastic? (then install backer board and then te tile) or take the plastic out and install green sheet rock and then backer board and then install tiles?I hope somedoby can help me! thank you
