The place is very close to where the Gym used to be and there is even a sign at the old Gym location to direct to the Boilerhouse. I was there on Saturday afternoon and the Gray factor was 50% or even more. Cruise factor verrrrry high! The Boilerhouse is owned by the same people who run The George (see bars). It has a cafe and changing rooms on the ground floor, then goes up a further 4 floors with a sauna, steam room, video room and many private cabins. Free condoms and lube.
