The biggest sauna at Thermae Grimbergen is a traditional Finnish Kelo sauna where two Aufguss sessions are organised daily.

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.
These messages are definitely worth a quick read!
