Bilevel house, 25 years old (my first year in it). Electric baseboard heat. The main bathroom is on the main level (above ground). It is about 6 X 11, carpeted, and currently does not have an exhaust fan. I am afraid of getting mold in the room, since we did get some in our garage in the lower level (part underground), and my wife and I take 15 minute hot showers within the same hour in the morning. During the summer we just left the window open all the time, but it was still very humid due to the extremely humid summer we had - and I can't do this now (I live in PA).
Common solution would be an exhaust fan, but this would lead to some heat loss through the vent (that is why prior owner did not put a fan in) and would cost $400 to install by an electrician. I am wondering if using a small dehumidifier would be just as good. We can also continue to leave the window open during warmer months.
Any suggestions? Thank you!
