In steamy bathrooms, high relative humidity encourages bacteria, mildew and mold. It’s important, then, to keep humidity low. But how?

HEAT EVAPORATES HUMIDITY. A small space heater, wall heater or overhead heat lamp will dry dampness left over from your shower.

VENTILATION IS THE MOST EFFECTIVE WAY to control humid­ity in a bathroom. This can be accomplished by opening a window or turning on an exhaust fan while showering. Make sure your fan vents to the outside of your home—not to the attic.


• Dry damp surfaces before mold can grow. After each shower, towel off the walls, floor, and other wet surfaces.

• Fabric tends to hold water and host mold (cotton is particularly prone). Don’t install carpet in the bathroom. Wash bathmats frequently; damp bathmats left on the floor can grow mold. Make sure towels are laundered or hung to dry. Pull cotton shower curtains outside the tub to dry, and wash frequently.
