The Celestine sauna is situated under the restaurant at Thermae Grimbergen. It’s a small cosy sauna with a special stone in the middle of the cabin: a celestite crystal. This crystal has calming properties and promotes a peaceful night’s sleep
With a temperature of about 75°C, this is a very dry sauna, so even sauna novices will be able to tolerate this temperature quite well. The stove is hidden under the benches and there is a cold plunge pool next to the sauna to cool down in.
