Timelessly handsome

HANSAPRISMA is a classic amongst thermostats. Timeless design meets practical utility. It makes the bathing and showering experience safer and significantly more agreeable. Both the THERMO COOL function as well as the 38 degrees Celsius safety stop contribute to this.

Water temperature always appropriate

The elegance of the HANSAPRISMA thermostat, available for both bathtubs and showers, enhances every bathroom. The emphasis is on safety in addition to convenience. So the water always remains at an acceptable temperature: A safety stop that is pre-set to 38 degrees Celsius provides for reliable scalding protection. However, if you need hotter water, you can release the lock by pressing a button to increase the temperature. A temperature lock that can be retrofitted ensures the safety of children, the elderly or people in need of care. This solution fully locks the button.
