On average, baths use more water than showers do. And let's face it, you'd probably have to clean out the tub before using it, anyway.
A typical bathtub holds 60 gallons of water, while a 10-minute shower under a low-flow showerhead uses only 25 gallons.
Because a significant portion of the water you bathe in is heated, showering also saves energy. That means fewer greenhouse gas emissions and more money in your pocket.
If you're a bath-taker, consider replacing one bath a week with a shower. You'll save an average of 1800 gallons of water per year, and more than $10 in water and energy costs.
If 1 percent of U.S. households replaced one bath per week with a shower, the water saved would equal nearly 2 billion gallons annually-imagine a 7-foot tall bathtub the size of New York City's Central Park, filled to the brim!
