This touchless bathroom faucet uses an infrared motion sensor to start and stop water flow automatically for convenient, hands-free operation. A single-handle mixer and under-sink temperature control valve let you adjust between hot and cold water with ease. The brass construction and brushed nickel finish are designed for durability and resistance to rust in damp environments. It fits most standard sinks with a 9/16" hose connector and includes a flexible hose for installation. Battery-powered operation allows for cordless use and simple maintenance.
