Not that I know of, but ping me with a PM if you find one, please!
As far as I know, Helsinki Health Spa in Ipswich is the nearest, and I just read that it's probably closing down soon.
Never found one when I lived that side of the border. I’m usually right on the boundary these days so Ipswich would be a hundred miles away. If I ever get round to visiting one I’d probably be closer to one by travelling north or west.
