Single-lever-handle single-hole deck-mount kitchen sink faucets have one L-shaped handle that users pull toward or push away from themselves to start or stop the flow of water. They 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.
Gooseneck-spout faucets have a tall spout shape that extends high above the counter and curves to point straight down into the sink. The tallest spout shape available, gooseneck spouts provide the most distance between the spout and the counter, making them ideal for filling stockpots and other tall vessels.
Low-arc-spout faucets have short spouts that sit close to the sink basin. They are frequently used on high-traffic sinks in public or commercial areas because they minimize the distance water travels from the spout to the sink, which reduces splashing.
Double-joint-spout faucets have spouts with multiple joints that allow the faucet to be bent into different shapes to adjust the reach of the faucet and deliver water where it is needed. They are used in commercial kitchens.
