Thermalsolbad Salzgitter-Bad

The Thermalsolbad stands at Parkallee 3 in Salzgitter, in the Salzgitter-Bad district, and is run by Bäder, Sport und Freizeit Salzgitter GmbH. The water is brine, and the brine is genuine: the operator calls it Natursole and gives a salt content of about 2 % in the bathing pools, and states that Salzgitter-Bad is a state-recognised place with brine cure operation, its physiotherapy practice holding the status of a Kurmittelhaus. It is supplied by a borehole 243 metres deep, sunk on the grounds of the old saltworks and delivering brine of 20 to 25 %; the borehole feeds the bath, opened on 16 February 1972 east of the Greifpark. The concentrated brine is therefore diluted heavily for the pools, and the operator publishes no conversion.

Despite the name, the operator names no thermal spring, gives no source temperature and publishes no water analysis; Thermal is simply part of the venue's name. For the borehole a depth is known but no source temperature and no analysis, and its yield is described as brine rather than as thermal water. The published pool temperatures of about 30 to 35 °C are operating temperatures of heated water, not a spring temperature. The Thermal in Thermalsolbad is backed by no source: this is a brine bath (Solbad) with a deep brine borehole.

The bathing area is the Solewellenbad. Its wave pool holds brine at about 30 °C with a salt content of about 2 %, and the wave machine starts every day on the hour. A brine outdoor pool, open all year, runs at the same temperature and salt content, so that swimming in the open air is possible in sun, rain or snow; the operator names massage jets, floor bubblers and neck showers, and a sun terrace, lawn and rest loungers. A whirlpool runs at about 35 °C. Water gymnastics runs Tuesdays 13:15–13:30 and Fridays 10:15–10:30, not on public holidays or in the school holidays.

The Sauna-Land has a herb sauna with colour-light therapy at about 50 to 60 °C and 35 to 45 % humidity, a Finnish sauna at about 90 °C and 5 to 15 %, a log-house sauna at about 85 °C and 5 to 15 %, and a brine steam bath at about 45 °C and 50 to 70 %. It also has a brine relaxation pool at about 34 °C with about 4 % salt content — twice the concentration of the main pools — plus a sauna garden, experience showers, a bucket shower, rest loungers and a winter garden. Men's sauna runs Wednesdays until 18:00 and ladies' sauna all day Thursday. The bath is closed Mondays and opens Tuesday to Friday 9:30–21:00 and Saturday and Sunday 8:30–19:00, with bathing ending 20 minutes before closing; the sauna runs to 21:30 on Tuesday to Friday.
