Product Details

Each hai shower houses a hydro-powered micro-turbine which generates energy from water flow alone!

Our hai showerheads are built to fit majority of the standard US wall shower arms!

If for any reason, our hai showerheads do not work for your configuration, please reach out to customer support at We're here to help!

You need a smartphone compatible with iOS or Android platforms. On iOS, the App supports version 13 and above. On Android, the App supports version 8 and above.

The EPA's WaterSense certification is awarded for eco-efficient showerheads using less water without compromising the shower experience.

Our 1.8 gpm showerheads do exactly that, requiring less water for the same amazing hai shower!

The hydro-powered turbine tracks water and energy used over time. The turbine powers our Bluetooth technology that broadcasts that data to our mobile app.

You can track your usage and set LED alerts on the showerhead using our hai mobile app to help you improve your water usage at your own pace.

You can track water and energy used overtime (based on water temperature) as well as time spent in the shower.

The default LED alerts are set to tell you that the water is warm at 90°F with a green light for "go".

When you've used about 17 gallons, the light will turn orange to signal it's almost time to get out of the shower.

Both of these colors can be customized in settings!

Yes! All hai LED alerts can be customized with the color of your choice (along the RGB scale) or turned off altogether.

Go to your hai app settings to customize your light show!

The Bluetooth broadcasting range is 10 meters, line of sight. Thick walls between the devices can affect signal and connectivity.

Yes! All technology is enclosed in waterproof protection to make sure everything is functional and safe.

It's our way of keeping your account secure! The verification code is an alphanumeric, 6-digit security code that is used to prevent cases of unauthorized access to your showerhead.

The turbine is designed to last the lifetime of the product under use (10 years, 15,000 shower cycles).

However, after installation, if your hai shower sits idle for over a year, the battery will die. So make sure to keep clean, shower on!

The moment the showerhead transfers your shower data to your app, it will be removed from the showerhead and live on the app.

If the data does not successfully transfer to your app, the showerhead will be able to store it for up to 100 showers (after that, it starts overwriting your previous showers, starting from the oldest).

Give up to 5 min for your most recent shower data to transfer onto your app!


If pliers or a wrench doesn't do the trick, you can use a penetrating oil (like WD-40) to help loosen it up!

Although our clamp was built to prevent leaking, some older pipes require a new layer of teflon tape to secure leaks.

Remove your showerhead, then apply a layer of teflon tape over your shower arm clockwise.

Now reinstall the showerhead again.

Take your time to gently peel back the tape. This will help most of the sticky residue stay on the tape instead of the piping or fixture. Once the tape is removed, use a wire brush, an old toothbrush and a clean cloth to remove the stubborn bits.

Go to your local hardware store or buy one online. They should have the tools you need! 


Yes, your shower will work– except the LED and tracking capabilities.

You may have had a showerhead with a different gallons-per-minute flow rate than the one you purchased.

Recently, some states have enacted tighter restrictions on showerhead water flow, so your old showerhead might have a higher flow than what's now legally allowed to be sold.
