I am trying to find somewhere to rent a permanent locker (to keep a suit or two, shoes, toiletries) and shower (with towel service). So far, I have only found a convenient but expensive ($200/mon) health club (Equinox on Monroe) and the Millennium Park Bike Station which has a great price ($200/yr) but is too far from my office (1 mile). Dressing up and working downtown makes bike commuting more complicated.

I hope someone else on the forum has figured this out! Thanks for any advice!
