The sauna cabin is made of kelo wood, a typical wood used in saunas. It absorbs heat well and then slowly releases it. That makes this the ideal sauna for steaming Aufguss sessions!
The temperature is about 85°C, but during an Aufguss session this obviously goes up even more. The huge fire is not the only eye-catching feature in this beautiful sauna. It also has a massive TV and an amazing music system. These were installed so that we could give show Aufguss sessions. During these sessions, the Aufguss master chooses from a selection of no fewer than 16 different essential oils and uses ice balls or creates a themed session!
After a session in the Kelo sauna, you can cool down in the natural swimming pond. The Kelo sauna is situated right next to the pond, in the nude area.
