    Gjosa uses every last drop of water wisely while saving up to 80% on water and up to 60% on energy

    A game changer

    Swiss innovation setting the sanitary standard for the future

  • Gjosa transforms water into a fine powerful spray. The technology is based on pulverization of water enabling an unprecedented low flow rate.


    It uses water wisely to the very last drop, saving up to 80% on water and up to 60% on energy, with only 2 liters of water per minute. It also has the unique ability to dispense cosmetic or hygiene lotions within the flow, opening to new market segments.


    The Gjosa technology has been invented by Elmar Mock, the co-inventor of the SWATCH watch, and a spin-off from Creaholic, the renowned Swiss innovation house. It benefits from a solid, global and mature portfolio, and from co-development with Bosh. Gjosa offers not only a new comfort level, but also combines Swiss proprietary technologies and respect for the environment.


    Gjosa is setting the sanitary standard for the future.
