Sinks are fixtures used for washing hands, dishes, and other items. They typically consist of a basin that holds water and a drain that allows wastewater to flow away. Sinks can be made from various materials, including stainless steel, porcelain, and composite materials, and are commonly found in kitchens and bathrooms. Faucets are devices that control the flow of water into sinks. They usually have handles or knobs that adjust the water temperature and pressure. Faucets can be single or double-handle designs and may include features like pull-down sprayers or touchless sensors for convenience.
