Extract moisture by installing a ducted exhaust fan on a timer. Most timers allows you to set the fan for 15 to 60 minutes to remove heat, steam and condensation. Choose a fan according to the cubic feet per minute of air it moves. To find how out much you need, divide the cubic footage of the room by 7.5. Look for a fan that generates 6.5 sones or less of noise.
Adequate lighting is needed for shaving, applying and removing makeup and other grooming tasks.
Include task-specific and ambient, or general, light. Flank the vanity or pedestal lavatory with a pair of decorative sconces or multibulb theatrical strips. And avoid fluorescent lights, which alter the color of your complexion. And, if you like to relax while soaking in the bathtub, install some of the bathroom lighting on dimmer switches. Finally, admitting natural light with skylights, etched glass, transom windows and glass block is an effective way to maintain privacy without taking up additional space.
