Take control of your shower with the Grohe New Tempesta Cosmopolitan 160 shower system with thermostat The Grohe New Tempesta Cosmopolitan160 shower system with 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 Water Guide 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 Turbos tat to let you set the temperature instantly and reliably, while the Grohe Safe Stop 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.
