Unison as a tap system provides an alternative to the tap sets and mixers currently available on the market. Unison integrates flush with any surrounding finish, thus providing new aesthetic opportunities for wet areas. Unison translates a smooth pulling action into easily regulated water flow. The motion opening and regulating the water flow is simple and obvious even to the first time user. This new type of design will spawn an entirely new generation of taps as alternatives to currently available tap sets or mixers.
