We all have our own towels plus I have a separate hair towel and we also have a hand towel. I wash once a week if I remember but the hand towel gets washed more often. I never wipe up anything other than bodies with the bath towels. Our towel rail is above the heating duct so they dry quickly and if anyone forgets to hang their towel up, tough - they have to get dried with a damp towel. They don't seem to forget too often after that

I can't bear the thought of wasting that much water and electricity on washing towels that have just been used to dry something that has been washed - but that's me. I'm more of an enviro green freak than a clean freak so my priorities may be different
