Vapor barrier or no?
5x8 bathroom. 5' wall parallel to bath is cinder block and will be framed out with 2x4 and insulated. Adjacent walls are 2x3" framed. One backs to a bedroom that has rockwool insulation in it. The other (shower head side) backs to the other shower in a utility wall.
Should I install any vapor barriers before installing backer board? Seems like it would make sense.
