Most kitchen sinks have three parts: the sink basin, the faucet, and the drain.
The sink basin is the actual bowl part of the sink where water collects. It is usually made of stainless steel, porcelain, or another type of durable material. The basin may also have a coating that helps resist stains and corrosion.
The faucet is what you use to turn on the water flow to the sink. It is typically made of brass, chrome, or another type of metal. There are many different types and styles of faucets available on the market today.
The drain is located at the bottom of the sink basin and allows water to exit through a pipe connected to your home's sewer system or septic tank. The drain usually has a stopper that can be used to block off the flow of water when needed.
