Want to save water? Take a look at what’s in your bathroom. Showerheads installed before 1992 can pump as much as eight gallons of water per minute. New low flow showerheads are inexpensive, emit less than two gallons of water per minute and easy to swap out.
But habits can save water quicker than hardware. The average shower uses about four gallons of water; the average bath uses 50—so even if you’re a showeraholic, it’s still better than a bath.
You can take a “navy shower” by staggering your water usage: Get wet, turn off the tap, lather up, turn on the tap, rinse off. Then cut consumption in half by showering with a friend.
