Flow Loop


Flow Loop makes a shower panel that can save up to 85% water and 75% energy while providing a much better flow than a standard shower. This is achieved by continuously filtering, purifying and recirculating a small amount of water. Thereby Flow Loop uses only 15% water and 25% of energy compared to a standard shower while providing better comfort and even limiting lime scale in shower space. At Flow Loop we have a vision to change the way we use water as a resource and help to secure sufficient clean water in the near future. We believe the best way we can do this is to provide innovation that changes how we use water in our homes and support the integration of sustainable living into the mainstream market. By doing so we also aim to change the mindset towards the way we use water as a precious resource and advance public awareness towards a more sustainable future. Our goal is to change the way we use water in our bathrooms and ultimately our homes. Our mission is to provide solutions for any household – solutions that are affordable, accessible and attractive. We want to create a new standard for efficient use of water (and other resources) in the shower – and to provide smarter water solutions for any bathroom/home. We want to drive innovation and deliver solutions for a more sustainable living without compromising comfort or convenience. We aim to deliver retrofit solutions, that will require a minimum of change to the existing infrastructure.
