The Cieplice Baths uses low mineralized, fluoride-silicon waters with temperature silicon outflow of up to 87°C and with high silica content among all other spring waters through the whole Europe. Additionally, in order to balance the composition of the water in the basins of the pools, the pool uses water from the city infrastructure.
In our thermal pools, there is also water from hot underground sources of borehole, being taken from the depth of 2000m. Unique health properties of our water have been known for hundreds of years. The thermal water from Cieplice warms, prevents formation of stones in the urinary system, increases bone mineralization, prevents tooth decay, increases micturition and diuresis, and has antibacterial properties. Pools and Jacuzzi tubes are filled with water, to which we give an optimal temperature in the range of 27°C - 36°C.
