I'm remodeling a bathroom in a wood frame building with a masonary façade, circa 1960. Before the plumber comes to install the tub, I'm wondering how to insulate the one exterior wall. There was no insulation previously.
On this wall, above the tub, I plan to furr out the existing furring strips and attach cbu so that it extends over the tub lip and is more or less even with the surrounding plaster wall, then apply a liquid membrane/vapor barrier to the cbu, and install tile.
I'm not sure what to do in the cavity below the tub lip. Once the plumber installs the tub, there will be limited access to this area.
I was thinking about gluing 1" thick foam board to the brick, between the furring strips, on the entire wall. In the portion below the tub, should I apply a vapor barrier and a sheet of cbu?
