With Quoss patented technology, the Reno Transformer Freestyle Shower Mixer product transforms your old 2 taps into an exposed single flick mixer system. Installation is an easy retrofit that takes less than 30 minutes, with no extra work such as breaking the tiles, drilling holes in the wall, plumbing, or piping. Once installed, there is no longer any on-going maintenance like changing spindle washers or re-seating the valves regularly, as the exposed mixer prevents drips and leaks permanently. The whole system is interchangeable, so you can even take it with you when you move out without leaving any marks or traces.
