In the Metris wall-mounted mixer, the designers from Phoenix Design employed geometrical shapes to create a beautiful appliance that conveys a sense of momentum and precision. The flat lever is arched slightly, giving a perfect ergonomic feel. Precise edges and gentle curves merge in a rectangular spout. The mixer is framed by a rectangular escutcheon with slightly rounded corners. The aerator integrated into the spout limits the flow to an economical five liters per minute, while still producing a gentle, voluminous flow.
