Showering is one of the leading ways we use water in the home, accounting for nearly 17 percent of residential indoor water use—for the average family, that adds up to nearly 40 gallons per day. That's nearly 1.2 trillion gallons of water used in the United States annually just for showering, or enough to supply the water needs of New York and New Jersey for a year! By retrofitting your shower with a WaterSense labeled showerhead, you can save a considerable amount of this water.
Shower With Power
Did you know that standard showerheads use 2.5 gallons of water per minute (gpm)? Water-saving showerheads that earn the WaterSense label must demonstrate that they use no more than 2.0 gpm. The WaterSense label also ensures that these products provide a satisfactory shower that is equal to or better than conventional showerheads on the market. EPA worked with a variety of stakeholders—including consumers who tested various showerheads—to develop criteria for water coverage and spray intensity. All products bearing the WaterSense label—including water–efficient showerheads—must be independently certified to ensure they meet EPA water efficiency and performance criteria.

Look For The WaterSense Label
offer rebates and vouchers that can lower the price.Whether you are replacing an older, inefficient showerhead or simply looking for ways to reduce water use and utility bills in your home, look for the WaterSense label on showerheads along with faucets, faucet accessories, and toilets to help you identify models that save water and perform well. In many areas, utilities
The average family could save 2,700 gallons per year by installing WaterSense labeled showerheads. Since these water savings will reduce demands on water heaters, they will also save energy. In fact, the average family could save more than 330 kilowatt hours of electricity annually, enough to power a house for 11 days.
On a national scale, if every home in the United States installed WaterSense labeled showerheads, we could save more than $2.9 billion in water utility bills and more than 260 billion gallons of water annually. In addition, we could avoid about $2.5 billion in energy costs for heating water.
Tip: It's also a good idea to check and, if needed, replace the washer or "o" ring inside the showerhead while making this repair.
In July 2018, EPA released a revised version of the WaterSense Specification for Showerheads (Version 1.1). The specification changes are minor and clarify the existing requirements for a showerhead to qualify to earn the WaterSense label. The changes also reflect recent revisions to the American Society of Mechanical Engineers (ASME) A112.18.1/Canadian Standards Association (CSA) B125.1 Plumbing Supply Fittings standard, which is now consistent with the WaterSense Specification for Showerheads. The specification updates ensure that WaterSense labeled showerheads are tested, marked, and labeled consistently and will continue to meet EPA’s criteria for water efficiency and performance..

Version 1.1 of the WaterSense Specification for Showerheads also revises, through reference to ASME A112.18.1/CSA B125.1, the spray force performance testing protocol to accommodate water-efficient rain showers. More information on the changes to the spray force test protocol and criteria can be found in WaterSense’s Explanation of Showerhead Performance Testing.

Version 1.1 of the WaterSense Specification for Showerheads replaces Version 1.0, which EPA released on March 4, 2010. For more information about the WaterSense specification development process for showerheads, please see the Specification for Showerheads Background Materials page.
Manufacturers that produce showerheads meeting EPA’s efficiency and performance criteria can apply to have their products certified to earn the WaterSense label. Before submitting products for testing, manufacturers must have a signed WaterSense partnership agreement with EPA. Visit the Join WaterSense page to learn more about partnership.
