Greetings all,
Got my tub shimmed and in place now in the tub alcove. I got some 6 mil vapor barrier and I am ready to put that up before I get on to the cement boarding and tiling and such.
My question is though, do I vapor barrier all three walls of the surround (it's a right drain alcove so I have the left wall [exterior wall], back wall, and then the right wall [where the plumbing is]) or just the back and left walls?
Oh, quick addon question, do I need to use cbu on the back side of the wall with the plumbing? or just the side that faces the tub? I'll throw in a quick terrible diagram explaining (I mean do i need to use CBU on the red line in the diagram below or just in the gold areas?):
Thanks!
