Cassiopeia Therme

The Cassiopeia Therme is a thermal bathing complex in Badenweiler, in the southern Black Forest. Operated by the Staatsbad Badenweiler, it combines mineralised thermal pools with a modern sauna area, a Roman-Irish bath and a wellness area, and continues the local spa tradition connected to the region's roughly 2,000-year-old Roman thermal culture and the town's well-preserved Roman bath ruins.

Thermal pools

The bathing area has a total water surface of over 1,000 m². It includes the Dome Bath at 32°C (used for water gymnastics and aqua fitness), the Marble Bath at 34°C with massage jets and two bathing grottos at 36°C, a whirlpool at 36°C, and an outdoor pool at 32°C with a current channel, massage jets and a neck shower offering views towards Baden Castle. A cold-water treading pool is kept at 12°C.

Sauna World

The Sauna World has six saunas: a Stone Bath (55°C), Aroma Sauna (65°C), Herbal Sauna (70°C), Infusion Sauna (85°C), and Finnish and Crystal saunas (both 90°C), with both indoor and outdoor saunas. It also features a textile-free thermal pool with a 150 m² water surface. Seasonal infusions use essential oils such as eucalyptus, mint, lemon and cinnamon. A ladies-only sauna runs on Wednesdays from 10 am to 3:30 pm. Minimum age is 12.

Roman-Irish bath

The textile-free Roman-Irish bath follows a sequence through a cool room, a warm air room (50°C), a hot air room (60°C) and a steam bath with essential oils (50°C), followed by a 36°C thermal pool and a 12°C plunge pool, then rest on the terrace or in the relaxation room. An optional soap brush massage is available for €15. Minimum age is 12.

Wellness

The wellness area offers massage treatments, described by the operator as helping to loosen tension and promote blood circulation in tissue, skin and muscles.
