About this place Saunaland Aquarium

The Aquarium Sauna — also listed as Saunaland Aquarium — is Karlsruhe's only dedicated gay men's sauna, in the Mühlburg district at Bachstraße 46. Spread over roughly 600 m² and three floors, it offers a Finnish dry sauna, steam bath and whirlpool alongside the usual gay-sauna facilities: a darkroom, video lounge and private cabins. It is a men-only venue; women are not admitted. Long established on the regional scene, it is the standard indoor option for gay visitors to Karlsruhe and is listed in the major German gay sauna guides. Opening hours and any theme days are posted on its website, aquarium-sauna.de. For a larger bathhouse, the nearest options are the gay saunas in Mannheim and Stuttgart.

Great. Clean. Excellent value for money. Lovely atmosphere, friendly people. We were able to completely relax. Thank you! We'll be back! However, what was a little bothersome was the woman (TS) who was running around fully clothed. It was disruptive in an area where people weren't wearing clothes or were only wearing a towel.

Aquarium was the first gay sauna I ever visited when I was 20. Several years have passed since then, and I still love it. I've since been to many other saunas, for example in Berlin, Cologne, Amsterdam, Brussels, London, and Valencia. And I think Aquarium definitely holds its own. On the contrary, some other saunas could learn a thing or two from it. Internationally, it's a hidden gem. The sauna is clean, offers good value for money, is often busy, and probably attracts an international clientele (of all ages) due to its proximity to France. Spread over three floors, there's a whirlpool, a steam room, a labyrinth, free lockable cabins with loungers, loungers next to the bar, a cinema, several dry saunas, and even sauna infusions. The only thing I would change is that the temperature in the whirlpool and showers could be a bit warmer for my taste. If you haven't been yet, you should definitely try it. I highly recommend it.

You guys are heroes! Spotlessly clean. You can walk barefoot on the underfloor heating on several floors. Delicious bistro. If you're not happy here, whether you're enjoying the whirlpool, dry sauna, or steam room (all cabins included in the price!!), then there's really no helping you. A tip for the stressed-out, whiny reviewers: just stay home! 🤣

Hello, The sauna is clean and well-equipped at an attractive price, but there are a few minor drawbacks: - Too crowded on Sundays - Impossible to fully enjoy the facilities - No ventilation or air conditioning (unbreathable atmosphere) - Musty smell in the hammam upon opening - Changing rooms are too small - There should be a maximum number of customers allowed.

It was my first time there today, and the sauna is really good. There were a variety of visitors, and the sauna and whirlpool were excellent. What really bothered me, though, were the fish in the far too small aquarium filled with dirty water. That's just unnecessary. They should have screens showing underwater scenes or something similar; those poor animals really don't belong there.

A wasted Sunday afternoon. No country (sauna) for older men.
