The shower system with the thermostat is a high-performing system that will add comfort, convenience, and a touch of luxury to your showering. Switch easily between the hand shower and the showerhead. A super-insulated Inner WaterGuide directs hot water away from surfaces to stop them from getting too hot and to protect the shiny chrome finish, while the horizontal shower arm swivels through 180˚ to increase coverage. The thermostat is fitted with Grohe TurboStat to let you set the temperature instantly and reliably, while the Grohe SafeStop button limits the water temperature to a maximum of 100˚F/38˚C, great for giving children independence in the bathroom, but can be raised for adults.
