Showering to Savings. In an average home, showers are typically the third largest water use after toilets and clothes washers. The average American shower uses 17.2 gallons (65.1 liters) and lasts for 8.2 minutes at average flow rate of 2.1 gallons per minute (gpm) (7.9 lpm).
The Environmental Protection Agency estimates that showers account for nearly 1.2 trillion gallons each year--about one-sixth of all the water used in U.S. residences for bathing. Before 1994, showerheads typically had a flow rate of 5 Â½ gallons per minute. Since then, the Department of Energy has limited showerheads to 2 Â½ gpm to conserve not only water, but fuel for the water heater. Models that display a WaterSense label use no more than 2 gpm.
