Vapor Barrier behind shower
I had a new bathroom installed in basement. The one piece shower was installed directly on a concrete exterior wall and wooden shelves were built next to shower also directly on concrete wall. I can see no insulation or vapor barrier was put on before installation. My licensed plumber claims they are not required. Please tell me if I'm going to have a mold problem I need to know before the plumber finishes.

Hi HR
It doesn't sound right to me... ;) I would think the concrete wall should have been firred out with strapping (at a minimum and then filled with a 3/4" foam insulation (at a minimum), but I got to tell you, every state will have a different answer on this as codes differ state to state. I would contact a local building inspector (next town/city over) and simply tell him that you have a contractor bidding a job and he has proposed putting the one piece shower directly on the outside wall with no insulation or vapor barrier and see what he thinks, OK? Please report back on the results... community here would appreciate that! Good luck! Mark |
