I’ve been to the Greenhouse in Newport, Wales. I have a nervous sub in Basingstoke whom I want to take to a similar set up. Anyone know of such a place?
As far as I know, the nearest saunas are Tropics in Portsmouth (maybe 30-45 mins away) and Touch in Swindon (about 45 mins). I don't know of anywhere nearer and I usually visit a sauna in London when I'm up there.
