vapor barrier when soundproofing a bathroom

Just wondering, should I use a vapor barrier over the soundproofing insulation when I do my bathroom walls? Any help is appreciated. Thank you.

You need a VB on exterior walls. Any interior walls don't need it. It is there to prevent warm moist air from migrating to the cold elxterior sheathing and condensing there.

Thanks, I knew that part, I was wondering if steam from the shower would affect the sound barrier. I guess it's pretty well sealed with gyprock, tape, and mud. =) Thanks again, it'll speed things up.

Your bathroom fan should deal with moist of steam from the shower. You should be running your fan 30 minutes after you are done showering. I installed a timer on mine to make it easy. It also helps a lot with odors.
