Fiberglass insulation in bathroom?

Can you use fiberglass insulation in a bathroom without vapor barrier?
it's all internal walls just doing it for sound

You dont need a vapor retarder on interior walls.

Um, if water gets to the fiberglass you have problems. Water and water vapor are not the same.

So, with water vapor the fan is good enough to remove any of it if it even got to the wall? I'm assuming green drywall and other stuff retards a lot of it being there anyway?
