It depends on how often you bathe. How often you change your towel when you do bathe. And how often you wash laundry. I shower every day and change my towel every other day but use a clean washcloth every day. I also have my own washer and dryer and am able to wash them as often as needed. If you have to go to a laundromat and only do laundry once a week or every two weeks, you would probably require more towels to last you until your next trip to do laundry. I have about twelve good bath towels, half for me and half for my boyfriend. And I keep several old towels to use for cleaning or if I have something really dirty or messy that requires a towel.
