It has been proven that an alarming number of bacteria can lurk on used bath towels. Your towel can harbor up to 650 million bacteria after being used for one week, including some harmful types that cause infections and even pneumonia. To prevent bacterial build up, towels need to dry thoroughly after every use, which is something heated towel rails do exceptionally well. Specifically designed to dry towels, the heat from heated towel racks kills bacteria and slows down their growth by up to 90% between uses.
Towels should ideally be washed after every 2 to 3 uses—except if you’re storing them on a heated towel rack. Using a heated rail to dry your towels after a shower or bath means that you will need to wash them less often—you can go up to two weeks between washes. This not only reduces your number of laundry loads, but it also saves water and is more energy efficient.
