The SmartControl rainshower system from Grohe allows the user to control and set all shower settings with a push-and-turn button, which has ridged edges for easier use with wet fingers. The shower features TurboStat technology, a metal thermostat handle that quickly delivers water at the desired temperature. A SafeStop button prevents users from accidentally raising the water temperature to more than 100° F, and CoolTouch technology prevents exposed metal surfaces from heating up. grohe.com/us
