I know there is another thread about this topic...but I had a few other problems to add to it, and didnt want to steal the spotlight away from her problems. I too have lots of mold and mildew problems in my bathroom. I dont have an exhaust fan, but am going to be puting one in. Here are my problems. I want to gut the bathroom, but there is no vapor barier, so if i take down the sheetrock on the ceiling, all of the blown in insulation from the attic will fall into the bathroom. im not sure if its sheetrock or plaster on the ceiling. Its sheetrock on the walls, but the ceiling is not level. its kind of wavy. Is there a way to smooth this out without having to tear down the sheetrock on the ceiling? Also, how do i go about puting an exhaust fan in, that vents out the roof. Also, can i put one with a light in it right over the shower, or put it in the middle of the room? Sorry for all of these questions. Thanks for your time!
