Insulating an interior bathroom

Hello all,
I'm considering unfaced fiberglass rolled insulation in interior bathroom walls just to cut down noise in adjacent rooms.

Any drawbacks to doing this? I know the reduction in sound isn't going to be anything great like using this [ATTACH=CONFIG]82206[/ATTACH] but it seems like a cheap attempt is worth a shot.

Fiberglass offers very little sound reduction. Look into Roxul Safe n Sound.

3 1/2 fiberglass insulation will do nothing, if you have a 6" wall there will be some benefit.

Couple years ago when I finished the basement I installed 3 1/2" and 6" of the recycled cotton insulation and it worked great for sound.

Sealing penetrations and gaps like electrical boxes and drywall to framing will help with sound transmission. Ditto on the suggested Roxul.

Great advice, I'll use the Roxul product in the walls and try a sound deadening caulk around boxes and between drywall/durock and studs.

Thanks everyone.
