Thoughts on whether or not I should put insulation and/or vapor barrier inside my interior bathroom wall?
I framed in my bathroom wall after I put my tongue and groove walls up (currently putting the tongue and groove on the bathroom wall).
I wanted to see what you guys think about whether or not I should insulate and/or use a vapor barrier/retarder in this wall?
I think pretty much the only reason I would insulate is if I wanted to keep sound from the bathroom.
It’s important to note, I will have a sliding barn door here, which will never fully block the sound and also an open joist ceiling (with no insulation). So It seems a waste of money to insulate this wall. With that being said, would you reccomend I use a vapor barrier/retarder membrane? Considering the rooms will be pretty much equal temperature I am thinking I will be ok without doing so.
For reference, I am in climate zone 3 Southern California 15 minutes inland of the beach.
I attached some pictures .
