RAINBOX SHOWER

The world’s most environmentally
& human friendly water recycling shower

With merely 100 liters of water, the RAINBOX SHOWER enables an average of 50 showers, while producing only 5% of the wastewater compared to an ordinary shower. The RAINBOX SHOWER purifies the water, removing shampoo and soap to produce soft water (gentle on skin and hair).Since the RAINBOX SHOWER does not require plumbing, the setup is quick and easy and only requires a power supply. Safety is ensured with real-time monitoring of the system which also allows pro-active maintenance and long-term optimization.

    

The RAINBOX SHOWER is appropriate for offices, sports facilities, outdoor facilities, temporary events, disaster relief, etc.
