To determine the right size of hot towel cabinet for your practice, you have to take into account the size of the salon or spa. The smallest hot towel cabinet holds about 12 small facial towels or washcloths, a standard one would be suitable from 24 up to 30 pieces, while the largest hot towel cabinet on the market has 45L and can hold up to 144 small towels. If your salon is small or medium-sized, the safest option would be an 8L hot towel cabinet. Make sure it also has a UV sterilizing function to ensure proper hygiene without taking up too much space or spending more on two separate units.
