All the operating functions of the EVIAN shower are contained in its stylish control elements. The front panel is made of glass, while the individual controllers feature a matt surface creating an elegant contrast. The central, round adjustment knob regulates the temperature and the amount of water, while two push buttons serve to swap between hand-held and overhead shower. The thermostat series comprises round and square control panels, as well as a variety of freely selectable surfaces that allow for flexibility in individual shower designs.
