The RainSelect concealed thermostatic mixer with 4 functions provides a user-friendly shower system. Large soft-click buttons with wear-resistant symbols divert the water between a handshower (sold separately) and the included showerhead. The easy to use knobs allow you to easily adjust your water volume and temperature. The high-quality finish is long-lasting and easy to clean. The shut-off function helps to stop water flow when pressure is placed on the Select buttons, adding an extra layer of security. The hansgrohe shower thermostat allows you to set your desired water temperature, protecting you from excessively hot or cold water. An extra safety lock only releases hot water once a button is pressed (SafetyStop). The elegant, concealed installation of the hansgrohe RainSelect shower thermostat creates space for care-free, unobstructed showering. This shower set requires the Rainfinity Rough set (Part No. 04865180) for installation.
