I have very poor airflow in my master bathroom. The vent fan seems to do very little, as even mirrors in my bedroom are getting slightly fogged up. Hanging towels don't fully dry between showers, and I'm afraid mold might start to grow. On top of that, the window is constantly soaked in condensation whether I've taken a shower or not. Last night, temperatures dipped below freezing for the first time, and this morning, when I opened the bathroom door, the entire ceiling was dripping with condensation. I'm not sure if these are two separate problems, or related, but I'd love some help with either one before mold starts to grow.
Thanks.

1. Leave the door open when not in use. I even leave mine open about 2 inches when showering. I don't have a fan, just a window.
2. Check the CFI number on the fan, and vacuum all around inside it (under the cover).
3. Consider installing a stronger fan if the CFI are too low (ask at any hardware store; measure your room).
4. Consider drying towels and bath mats elsewhere - I do, on a drying rack, to get them dryer faster.

I completely understand what your dealing with! For what its worth I can say open window prior to water warming and after leave dors/curtain open and here is the secret(no bs) lol but it works. Crack door and either cover up or do like me and rock the butt-naked damp towl helicopter spin move like your going to rope the toilet! Hey that issue really railroads my day often. Rope it!
