Use your exhaust fans to keep your bathroom from getting damp
We have already established that bathrooms are exposed to more humidity than any other part of the house. That can cause problems, such as bubbling in the paint or even mold growth in the ceiling. If you have exhaust fans installed, then you have a way to avoid the room getting overly damp every time you take a bath.
If you turn the fans on before you turn on the shower, then you will get air circulating, which will help clear up the moisture more quickly. That way, the walls will not be subjected to too much water damage and the paint job will last longer. The more you ventilate, the faster the steam will dissipate and your bathroom will stay nice and dry.
