Straight-spout faucets extend straight out from the body of the faucet and have a modern, streamlined appearance.,Sensor single-hole deck-mount bathroom faucets let users start or stop the flow of water without touching the faucets. This reduces the spread of germs and helps keep the bathroom environment clean. The faucets automatically turn off after a preset period of time to save water and utility costs and prevent the sink from overflowing. These faucets combine the hot and cold water supplies to come out through a single spout, and they provide water for handwashing and grooming tasks. Users cannot control the temperature of the water flowing through sensor faucets, so they must be preset to water temperatures that prevent scalding injuries. Single-hole deck-mount faucets install into one hole on a flat surface, such as a sink or counter.
