There was one on Kilnside Road, Paisley, in about '86/88. It advertised as a photographic sauna and I had a nice young girl in there. I got so excited that I forgot about the photographs. There was Lady Godiva on Cathcart Rd, near Crosshill station. There was Muirend Sauna on Clarkston Road, opposite what is now Sainsburys. I was never in the latter two, and they seemed to shut all of a sudden. I was told that it was due to licensing. It was a bit like the Wild West back then.
My favourites were,
Sauna Royal, Granville St. I can still remember young, pretty, and petite Chloe from there.
The one on Otago St with the red light outside the door. I can still remember Lynn from there. Was that Oasis?
The one on Crow Road.
In about May '93 I saw an ad in the Scotsman for Edinburgh saunas and started wearing the tarmac on the M8 after that.
