Meersburg Therme & Freibad

Meersburg Therme is a year-round bathing and sauna house on the shore of Lake Constance, operated by MeersburgTherme GmbH, whose Impressum gives the address as Uferpromenade 10-12, D-88709 Meersburg. The bath opened in 2003. In summer the same operator runs the adjoining Frei- und Strandbad, a lido with lake bathing.

The water is not documented as thermal. The operator's pages do not use the words Thermalwasser, Quelle, Bohrung or Heilwasser at all: Thermalbecken appears only as the name of one pool, Thermalbad in a footnote on children's admission, and Sole in the sense of a brine inhalation room, not of the bathing water. No source temperature, no well or borehole depth and no water analysis are published anywhere by the operator. The 2003 bath is described as having a "Thermal-, Erlebnis- sowie Eltern-Kind-Bereich", but no spring and no source data are named for it there either. On the published evidence, "Therme" here is a name rather than a statement about the water.

Pool temperatures are given individually in the operator's FAQ and no total number of pools is stated: the Thermalbecken is held at 34 °C and is fitted with massage jets and bubble loungers, the whirlpool at 36–37 °C, the outdoor sauna pool at about 30 °C and the plunge pool used after a sauna round at about 12 °C. An image caption on the Therme page refers to the view from an infinity pool over the lake. Alongside the pools the thermal area contains a textile sauna and a textile steam bath, a brine inhalation room, the air room called Grüne Lunge, a massage department and a gallery reached by stairs, which the operator names as the one part of the house that is not step-free.

The sauna landscape is headed "Fünf Saunen und ein Dampfbad". The bio sauna is run at 60 °C with 40–55 % humidity. The remaining four are described as a panorama sauna indoors and three pile-built cabins outdoors, the See-, Pool- und Lehm-Sauna, together "Insgesamt vier Saunen, die mit 80-100 °C Körper und Geist anregen", with a recommended 8–15 minutes per round and an hourly Aufguss ceremony. The textile sauna and textile steam bath in the bathing hall are counted separately from these five. The operator has dropped its Monday women's sauna day, and the sauna area is open to all guests on Mondays.

The operator gives opening hours for Therme & Sauna as Monday to Sunday, 10:00–22:00, with shortened or closed days published for the Christmas period: closed on 24 and 25 December 2026, 10:00–22:00 on 26–30 December and 10:00–18:00 on 31 December.
