Showerheads

The Lowdown

Showering accounts for 17% (3rd) of indoor water use.
Install a showerhead that uses less than 1.5 gallons per minute.

The Details

According to the EPA showering accounts for:

  • Nearly 17 percent of residential indoor water use or about 30 gallons per household per day.
  • Nearly 1.2 trillion gallons of water used in the United States annually.

By switching to EPA certified showerheads the average household could save:

  • More than 2,300 gallons of water per year.
  • 300 kilowatt hours of electricity annually used to heat water.

If every household in the United States switched to EPA certified showerheads we could save:

  • More than $1.5 billion in water utility bills
  • More than 250 billion gallons of water annually
  • About $2.5 billion in energy costs for heating water.

EPA certified water related items have the WaterSense label. The WaterSense specification essentially requires showerheads to have a maximum flow rate of 2.0 gallons per minute while still working well by maintaining a specified pressure and spray pattern. The details of the specification are available in the following pdf file:

This being said, most manufacturers have taken this a step further to reduce their flow rates on water saving models to at or below 1.6 gallons per minute.
