What's the best way to prevent mold in a bathroom with no window?
Answers:
An exhaust fan and keep the door open when possible. After showering use a towel to wipe the water off the shower walls. I also have a humidity absorber (desicant in a pail) that I cover when I shower and afterwards I open to keep the humidity down. I also suggest cleaning the grout and caulking on a weekly basis to stop mold from growing there.
If you like long, warm showers (like me) don't by a real cheap exhaust fan, get a decent one that makes little to no noise that you can keep running for a while after you bathe. (If you have to wire the fan into the light circuit switch the light bulb to a compact flourescent so you don't run the electric bill through the roof. And if you can't vent the fan to the outside it's OK to vent it into the wall/ceiling but remember mold can grow there too so you have to keep the fan on a while to disapate the humidity in the walls.)
Good luck.
