Learn How Rainstick Works
A traditional 10-minute shower uses 100 litres (26 gallons) of water.
RainStick uses less than 20 litres (5 gallons) while doubling your water flow.
Here’s how.




RainStick is a fully automated system that uses RainStick Original Cleaning Product. A cleaning session starts after each shower to guarantee each new use is hygienic.
We provide bathroom professionals with the tools they need to confidently install RainStick. A Pre-Installation Checklist and a Technical Specifications Sheet can be found on the Bathroom Professionals section on our website.
The Simple Explanation
Just like your current shower, RainStick starts with fresh grid-supplied water. Except, instead of going down the drain, RainStick captures, circulates, and cleans the water, all in real-time to avoid waste.
A Shower That Can Do Both
Flowrate:
11 Litres per minute / 3 Gallons per minute
Mode 1: Circulating Shower
Never before has it been possible to shower with up to 80% less water, and still get a high-flow experience. This is the default mode for RainStick, circulating water up to six times before it heads down the drain.
Flowrate:
6.8 Litres per minute / 1.8 Gallons per minute
Mode 2: Your Shower Today
RainStick's powerful water-saving features can be disabled at any time by switching back to this mode. Water flows from the spout to the drain, providing a single-use, low-flow 6.8 LPM / 1.8 GPM experience for times when you may be washing a pet, cleaning your shower stall, or hand-washing laundry.
What makes a good shower?
Flow
RainStick provides almost double the flow rate of a conventional shower. California and Washington have mandated 1.8 GPM and RainStick's flow rate is 3 GPM.
Coverage
RainStick offers a full-coverage rainshower experience that actually washes the shampoo out of your hair, while still providing up to 80% water savings.
Temperature
RainStick keeps you warm and comfortable for the duration of your shower. Whether you like to shower at 38°C/100°F or 42°C/106°F for example, the option is yours to pick your preferred temperature.
The Process
We have optimized RainStick’s technology to cleanse water in three stages:
The 3 Stages
- A micron-level screen catches larger debris such as hair and dirt.
- A tiny amount of fresh hot water is added to continuously refresh each loop and maintain the desired water temperature.
- A high intensity UV-LED disinfects water from bacteria and viruses.
In addition, RainStick automatically cleans itself in between sessions.
