Up to 20 prevention nozzles are integrated in the back and foot area, depending on the bath model. The water massage system specifically targets your back and feet. At just 19 dB per DIN 4109, Aquapuncture is one of the quietest water massage systems on the market. Only pipes with RCP (repaCLEAN Protect coating) and residual water drainage system are used to meet our own stringent hygienic standards. The automatic level monitoring ensures that the system is only activated when the tub is full.
