Tips on Keeping a Small Windowless Bathroom Dry

Many small or centrally-located bathrooms in homes do not have windows, which prevents the humidity from showering and bathing from escaping effectively. Humidity causes mildew and mould growth that can irritate people who are sensitive to it. The mould causes an offensive odour and unsightly growths on shower curtains, tile and other areas. Keeping your bathroom dry without a window is not difficult.

Exhaust Fan

Install an exhaust fan in your bathroom. These appliances are relatively inexpensive and are found at discount, home supply and hardware stores. Turn the exhaust fan on while showering or bathing, and leave it on for about 10 to 15 minutes afterward to help remove the steam from the area and circulate the air.

Light Bulbs

Low-energy light bulbs produce heat and light. Leaving them on for about 10 to 15 minutes after using the hot water helps dry the room out. The bathroom is one place where compact fluorescent bulbs are not the best choice since they do not emit heat.


Use your bath towel to wipe off bathroom countertops and inside the shower and tub area to speed the drying effect. Mop up any standing water to prevent mildew and mould growth. Another idea is to use a squeegee or sponge to wipe off the moisture on shower walls and other surfaces.


Open the door to your bathroom as soon as you are dressed. Leave it open while you are styling your hair or performing other grooming, which allows the moist air to escape faster, thus preventing mildew growth. If the bathroom connects to a room with a ceiling fan, such as in the bedroom area, turn it on to help dissipate the moist air. Another idea is to plug in a small oscillating fan to increase air circulation. Keep it away from any areas near water to prevent electrical shock.
