Yes they have towels. You need to have a Super Sport level of membership. I think they might also offer them for a fee. Update as of July 6 2019- This location no longer offers towel service.
They don't offer towels anymore that's wrong information. I just recently joined and asked this question before I got there. They replied and said no they don't offer towels anymore.
Actually yes and no. If you are a "Basic" member you do not get a complimentary towel. But half the attendants at the counter don't care about the rules and will give you a fresh (although often thread bare) when asked for one at any time. At the smaller 24 hour fitness around S.F. they are a little more strict, or fanatically strict. You have to pay extra for a complimentary towel. I prefer to bring my own Microfiber large adult towel, since it does a better job, than having to get an occasional stained or holey thread bare worn out yet clean - towel. But please bring a padlock, too many users leave stuff in unlocked lockers, expecting it to be there when they are done.
They have towels on the counter for everyone. You check in with fingerprint which I think is so cool. You can not have anything on you or lose everything and can still go to the gym, just know the phone number on file.
