DIY Towel Rack Ideas are one of the most important elements in any bathroom. You will always need a towel rack to avoid cluttering up your floor space with towels. Towel racks are very important in any bathroom. They eliminate the mess created by dropping towels on the floor and provide easily accessible storage for wet towels. The towel bars under your sink are usually too small to accommodate most towels, so you end up with a heap of towels lying around. Instead of buying a new and costly towel rack, why not DIY one for yourself?
