Even if you prefer long showers, you can still save water. A low-flow shower head will save 50 gallons of water during a 10-minute shower and doesn't cost that much to install. Most models have a shut off valve that will save even more water by stopping the water while you lather up. For bath lovers, a shallow bath uses less water than a 10-minute shower, so enjoy. Water-Stretching Tip: Placing a bucket in the shower catches water that you can use to wash the car, to water plants, or to clean most anything!
