Grohtherm 800 Thermostatic shower mixer 1/2″
matte black
The matt black GROHE Grohtherm 800 shower thermostat – precise temperature control, safety features and a stunning look
No more unpleasant temperature fluctuations while showering: engineered with the GROHE TurboStat technology, this GROHE Grohtherm 800 thermostat keeps the water temperature constant throughout your shower. Thanks to the wing-shaped handles operation is easy, even with soapy hands. For perfect safety in your bathroom, the GROHE SafeStop button is set at 38° C to prevent especially children from unintentionally turning up the water temperature too high. The GROHE SafeStop Plus temperature limiter can be set to maximum 50° C for an extra level of protection. And in case the cold water supply completely fails, an automatic safety shutdown reduces the water flow to a minimum. The GROHE Water Saving technology reduces water and energy consumption – and when you need a full flow just press the EcoButton to release the handle. And the hard-wearing and low-maintenance GROHE Long-Life finish keeps the matt black surface looking pristine for years to come. With a slimline, cylindrical body and a cool colour scheme it is perfect for creating a focal point in your bathroom.
