The Vevor touchless bathroom sink faucet uses an infrared sensor to start water flow automatically and shut it off when hands move away. Its chrome-plated brass construction is designed for durability and corrosion resistance in commercial or residential washrooms. The faucet is battery operated and installs with the included accessories for a straightforward setup. A honeycomb aerator helps soften the water stream and reduce splashing. It is built for cold-water use with a 9/16" hose connector.
