Vapor barrier in bathroom with no external facing walls
Hello folks. I am remodeling a bathroom that resides at the center of the house where none of the bathroom walls meet the outside of the house. Is a vapor barrier necessary? I will be adding mineral wool for sound reduction.
Thanks.
Thanks.

No and maybe.
No vapor barrier is needed.
As far as sound proofing goes it will help a little but not much. Sheetrock and studs along with the plumbing will transmit noise to the adjacent walls, the space between studs is not that much of a transmitter of sound.

vapor barriers, probably mean vapor retarder are only needed on exterior walls!
And agree with Norm, 3 1/2" of anything is not going to do a lot, soft touch and rock wool are better!
