Single-metering-handle single-hole deck-mount bathroom faucets have one handle that users manually push down on to activate the faucet. They let users control the start of the flow of water but not the duration, as the water flow shuts off automatically. Metering-handle faucets can be used to save water in public or high-traffic restrooms. They do not require users to grip the handle, which allows people with disabilities or limited mobility to operate the faucet. 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. Single-hole deck-mount faucets install into one hole on a flat surface, such as a sink or counter.
