WaterSense is partnership program sponsored by the U.S. Environmental Protection Agency that makes it easy for Americans to save water and protect the environment. Depending on how many water-saving fixtures you install, the number of people in your household and the age of your current fixtures, you could save $10 to $100 or more a year. Shop a wide selection of WaterSense toilets and faucets at ModernBathroom.com or visit the EPA website to calculate your water and energy savings.
