Frequently Asked Questions
How much water does a shower use?
An average 8-minute shower with a standard 2.0 GPM showerhead uses about 16 gallons of water. Low-flow heads can reduce this to 12 gallons.
How can I reduce shower water usage?
Install a low-flow showerhead (1.5 GPM or less), take shorter showers, and turn off water while lathering to reduce consumption significantly.
