Single-cross-handle single-hole deck-mount bathroom faucets have one cross-shaped handle that users grip and turn to activate the faucet. Cross handles offer high levels of control over water flow through 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.
