is there a steam room or sauna?

Yes, there is both a steam room and a sauna. The men's locker room and women's locker room each have their own facilities.

To use the nicer gyms at JFK and on Market, it’s $100 a month with a joining fee of $100. If you do some task they ask you to do, you can get it down to $90 a month. Only the center city locations have steam rooms. Fishtown and NoLibs locations don’t have steam rooms ... only dry saunas. If you join at the $60 a month rate, you can’t use the Center City locations. Having been to all the locations, it’s not worth the $60 to use Fishtown, NoLibs, etc, BUT, it is worth the $90 a month to use the center city locations.
