How many gallons of water does an average 10 minute shower use?

"A ten minute shower with a regular shower head can use as much as 42 gallons of water. A household of 3 people may take more than 1000 showers a year. This can be about 20% of the typical household's water usage." http://www.energyconservationinfo.org/day2.htm

One of the things most of us don't really think about, of course, is that there's an up to 30 second span there where we're trying to get the right temperature and water is running but not flowing over our bodies. If you live in an area where the water tends to flow plain ol' cold, outta the faucet, that waiting period can be longer. "Regarding showers, if you are one of those "ten minute shower people", now is the time to think about reducing the time in the shower with the water running. You can use the shut-off valve to turn off the water while soaping and scrubbing. Showers involve water and energy, and both of those resources are in increasingly short supply. If you think you can't live and function without a ten minute shower with the water running all the time, meditate a bit on your sense of personal entitlement.
