Both the control elements and the water outlet feature a circular form as a base. The stem-shaped levers and tap taper smoothly from the base, creating a flowing form that is repeated in other elements of the bathroom series. The material used is level 304-316 stainless steel, specified for medical use and widely used in implantation because of its non-corrosive qualities. It is also lead-free and has an antibacterial effect. The surfaces are easy to clean and offer a long lasting shine.
