Real-time filtration, purification, recycling & heat recovery system for showers. Made in Finland, for Earth.

OPEN SOURCE - OPEN HARDWARE - ECOLOGICAL - ECONOMICAL

Showerloop went into deep hibernation from covid which resulted in our team splitting up. Thanks to past donors that keep the website alive. There have been so many contributors to the project and I love all of them, but ultimately it wasn’t enough to keep me on the project.

If you want to contribute to the future of Showerloop please be in touch with me. Jason.selvarajan@gmail.com.

If you’re working on your own project and would like some consultation, I’m available for 100e/h <- to keep the website up.

Showers are great, but pouring hot and almost drinkable water down the drain is not. Besides the obvious costs to the environment and your bills, there is also a conscious on unconscious psychological cost any time you create waste. To solve this problem we created Showerloop. It's a shower that collects, cleans and reuses the water in real time while you are showering. So now you can shower for as long as you like but with a reduced ecological impact.

Showerloop is an open source hot water recycling system for super-efficient personal hygiene. The device captures shower water running down the drain, cleans it, and recycles it in real time, using around one-tenth as much energy and water as a conventional "linear" shower system.

We finally completed the first Showerloop Kit. Showerloop is a recycling system that lets you shower with 10 liters of water in a continuous loop. The water filtration system is designed to capture and clean the water in real time saving water and also hot water. Showerloop is open source so that anyone can build, make, adapt, improve and sell the system. It's being built by Jason Selvarajan and Eduard Kobak near Helsinki, Finland but there have been contributors and collaborators to the project from all over the world. This video was made in the studio/workshop of XYZ CARGO and N55 with the help of ROC21.cc, and friends from POC21. Special thanks to Timm Wille (co-director, co-cameraman and editor), Till Wolfer for hosting us in the workshop and providing a roof over our heads and Simon Kiepe for bringing us all together, Mauricio from Faircap for being my light and Vivi and Laurin from Sunzilla! If you'd like to contribute to the project we would super appreciate it.

What is the showerloop project ?

Showerloop vs Normal Shower

90% reduction in water usage and 70-90% in energy reduction for a 10 minute shower with a flow rate of 10 l/min. Savings are dependant on user behaviour and can vary. Use Just one bucket of water for a shower of any length. See the savings section for more information.
