Landgrafen-Therme

The Landgrafen-Therme is a thermal brine bath (Thermalsolebad) in Bad Nenndorf, Lower Saxony, operated as part of the Niedersächsisches Staatsbad Nenndorf. The facility combines indoor and outdoor bathing areas with a sauna landscape, a sea-salt grotto and a wellness area, and is fed by a naturally sulphur- and iodine-bearing brine spring.

Thermal water and source

The bath draws on the Landgrafenquelle (also called the Neue Landgrafenquelle), a thermal sulphur-brine spring tapped at roughly 300 metres depth and piped to Bad Nenndorf from Soldorf. The site describes it as an iodine- and sulphur-containing thermal brine, ranked among the strongest brines in Europe and among the strongest sulphur-bearing springs in Central Europe. As stated, the source emerges at about 21°C with a sulphur content of around 140 mg/l, a brine concentration of about 17 percent and an iodine content of about 2 mg/l. The water is desulphurised before use, and the bathing water is warmed to approximately 33°C at a concentration of about 2.5 percent sodium chloride.

Pools and features

The therme offers indoor and outdoor bathing areas with variable lighting. A Meersalzgrotte (sea-salt grotto) runs 45-minute sessions. The site also lists wellness and spa services including massages, cosmetics, wellness packages and a hydrojet massage.

Sauna landscape

The clothing-free sauna landscape includes a steam bath (Dampfbad) at about 48°C using essential oils, three Finnish saunas at about 95/80/80°C, a Galerie sauna at about 75°C built from Kelo pine and using natural birch-twig infusions, and a Bionarium at about 50°C featuring changing light therapy. Scheduled infusion times (Aufgusszeiten) run through the day.
