Mauritius Hotel & Therme

About

A 3,500 sq m sauna and pool floor beneath a hotel in central Köln, open to day visitors as well as residents. Seven saunas, a steam room, two whirlpools and an outdoor pool salted from the Dead Sea, with nine Aufguss ceremonies a day and massages to book. Entry from age 12.

Good to know

• Runs aufguss sessions: a guided löyly ritual where an attendant fans the steam around the room on a schedule.
• Hot tub on site: adds a warm-water option between the sauna and the cold plunge for a longer cycle.
• Set up outdoors: weather is part of the experience, so dress for the walk between cabin and water.
• Pool on site: works alongside the sauna for swim-and-sauna sessions or a longer cool-down between rounds.
• Restaurant on site, so long sessions are the design. Food is part of the visit rather than a stop on the way home.
• Pairs the sauna with spa services like massage or a scrub, so a session can sit inside a wider visit.
• Urban venue: it sits inside the city rather than at a coast or lake. A session fits into a day in town.

• Mon-Sun 10:00-23:00

The Therme's own price page gives 23:00; the hotel's page still says the spa floor runs to 23:30.
