Anyone around their 20s into the sauna scene? Need recs

Been exploring one of my biggest fantasies over the past year — saunas and being naked around other guys. There’s just something about that atmosphere that hits differently.

So far I’ve tried the main one in Amsterdam (loved it) and Sweatbox in Soho (not really my scene). I’m based in South Wales now and want to find somewhere with a bit more of a younger, open vibe.

Newport seems closest but I’ve heard it can be an older crowd. Touch Swindon on a Tuesday looks tempting — anyone been recently? Do many younger guys go?

Also open to any other recs around the UK worth travelling for — somewhere fun, chill, and a bit on the adventurous side 👀
