GROHE Precision Start bath thermostat – reliable, precise control for your bath

Love bathing but don’t enjoy having to check and recheck the temperature while it runs? With the GROHE Precision Start bath thermostat the GROHE TurboStat thermal element will keep the water temperature constant throughout. Just use the intuitive GROHE EasyLogic markings on the handle to select your temperature. It features an automatic bath/shower diverter and the GROHE EcoJoy function allows you to reduce water consumption in your shower by up to 50%. Families will love the GROHE SafeStop button which can limit the temperature to 38°C to prevent scalding. Plus the dazzling GROHE Starlight stainless steel finish is scratch-resistant and easy to clean for a pristine finish for years to come.
