A basin is a bowl-shaped container used for holding water or other liquids. In a bathroom, a basin is commonly used as a sink for washing hands and face, brushing teeth, and other personal hygiene tasks. Basins can be made of various materials, such as porcelain, ceramic, stone, or glass, and come in different shapes and sizes to fit different styles and bathroom designs. Some basins may have built-in taps, while others require separate installation.
