In a very beautiful architectural environment, adults can take a sauna and enjoy steam baths. The Bartholomew Therme has four saunas and baths. In the sauna at 90 °C there is an hourly infusion. A special highlight is the ice menthol crystal infusion with spectacular black light at 7 pm. Sauna guests can also enjoy homemade peeling and care treatments every day.
Every Thursday there is a ladies' sauna.
