This body of the shower system (diameter 20 mm) is made of chrome-plated stainless steel, the changeover between hand and head shower is done by a cartridge with a control dial (not by a pull lever), thus it is possible to switch continuously between hand and head shower (or even both can be used). The hand shower (diameter 90 mm) has five functions. The overhead shower has 200 mm. Both the head shower and the hand shower have anti-limestone knobs. The shower system is connected to the existing tap with an extra hose. All necessary installation material is included.
