One of the most common complaints today is back pain. The ergonomic arrangement of the 10 micro jet nozzles provides the maximum possible comfort and relaxation in the back and shoulder areas. Each jet nozzle can be individually directed at the tensed up area of the back. The system specifically loosens the tissues along your spine and around your shoulder blades with an aerated water jet, the Venturi system. The back massage concept can be installed in almost all Repabad bath shapes.
