Delta-faucet_HEROTouch2O technology lets users start and stop the flow of water by tapping anywhere on the faucet. It’s available in kitchen and bath lines and in transitional and modern styles. Unlike some touchless options, the tap-on-tap-off technology is intuitive and consistent, the maker claims. “It’s had a lot of good feedback,” says Sandra Moineau, options coordinator at Main Street Homes in Virginia. “You don’t know you need it till you don’t have it.” According to the manufacturer, the faucets work with any sink material—including stainless steel—though it advises against installing with a metal backsplash.
