After you enjoy a steamy shower, your bathroom walls absorb the lingering moisture, which can spur the growth of mildew. Choose a paint that resists mildew, or one that has a mildew-resistant additive mixed into it, to give your walls an extra measure of protection.

Keep It Well Ventilated

Mildew thrives in damp places, which makes the notoriously wet bathroom a prime breeding ground. To eliminate excess moisture, turn on the exhaust fan while you're showering and let it run for 30 minutes after you shut off the water. This ensures that the walls and ceilings will dry properly. If you have a window in the bathroom, open it a crack to air out the room as well.

You may be great about cleaning up the obvious pools of water by the sink and shower, but don't forget to deal with smaller drips as well. Take care of leaks under the sink or by the toilet as soon as you notice them. Putting off repairs lets more moisture into the room and can over time turn a small mildew problem into an even bigger headache.
