Bathroom Walls - Hardibacker, Densshield or Greenboard?
Hi, I am sure people have asked this question before but...DH and I are planning to redo our bathroom. Having difficulty finding a tile guy who does not have glazed look when I ask questions. (DH does not ask questions). This is my understanding as to what needs to be done but please correct me if I am wrong.
-Bathroom has two exterior walls and two interior walls.
-Studs & Joists are 16" oc. Ceiling Height is 101".
Attach 6-mil vapor barrier on the studs (walls and ceiling) and drape it into the shower pan liner.
Then install 5/8" Durock on the walls and ceiling. Do I need any additional blocking on the ceiling so Durock will not sag?
One wall of the shower is an exterior wall and we are using open-cell foam to insulate the wall. Will it be a problem with condensation due to open-cell foam and vapor barrier being adjacent to each other?
Preslope, Oatey Vinyl Liner, Mudjob, Thinset and tile. Trying to find someone who can install Kerdi.
Walls will have tile up 4 feet from floor with painted walls above. I am assuming that you don't need a vapor barrier here since there is no place for the condensation to drip into. Do I need to insulate the interior walls (I was not planning on doing so)? Use Durock for the tiled wall section (4'). Above that (walls and ceiling) what paintable substrate do I use? Hardibacker, Denshield or Greenboard?
What are the layers that go on the non-shower floor before tile installation? 3/4" plywood subfloor currently in place, Durock (what thickness?), Thinset and tile.
I greatly appreciate any help you can give me.
