Spout: The spout is the main outlet through which water flows. It can come in different shapes and lengths, and some faucets may have a swivel feature for greater flexibility.
Handles or Controls: Faucets usually have one or two handles that control the flow of hot and cold water. Single-handle faucets often have a lever that moves in different directions to adjust both temperature and flow, while double-handle faucets have separate controls for hot and cold water.
Valves: Valves inside the faucet control the water flow and temperature. Common types include compression valves, ball valves, cartridge valves, and ceramic disc valves, each with its own advantages in terms of durability and ease of use.
