Exstream

Throughout history, the WC has evolved and has been able to use less and less water for the cistern. Extream is a WC concept with a steam-activated cistern that allows the significant reduction of the daily use of water in households.

The system uses 0.5 or 1L of water, depending on the selected pressure based on our needs. This means four times less consumption on average compared to the most modern WCs and fourteen times less than the oldest WCs.
