Thermostat or faucet? Hansgrohe ShowerSelect has both. If water pressure is unsteady and temperatures fluctuating, a thermostat is the right choice. It constantly compensates for fluctuations toensure constant water flow and temperature. The same is true of both shower controls:Intuitive Select buttonswith easily understandable and abrasion-resistant symbols simplify operation. The protruding button indicates the active water source immediately. And its flush-fitting control buttons make ShowerSelect a breeze to clean after showering.
