WaterSense Meets EPA CriteriaIn addition to being lovely to look at, the Charlotte™ bath collection offers a luxurious way to live green. Like all Brizo bath collections, Charlotte™ lavatory faucets are WaterSense labeled, having been certified by a third party to meet U.S. Environmental Protection Agency requirements, flowing at a water-efficient 1.5 gallons per minute while maintaining performance standards. This reflects up to a 31% savings in water usage compared to other bath faucets.
