Single-side-joystick-handle single-hole deck-mount kitchen sink faucets have one handle that extends from the side of the faucet body and looks like a joystick. Users can grip the joystick and move it to control water temperature and 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 dishwashing, cooking, handwashing, and other tasks. Single-hole deck-mount faucets install into one hole on a flat surface, such as a sink or counter.
