A stone washbasin is a type of sink or basin that is made from a solid piece of natural stone material, such as marble, granite, or onyx. Stone washbasins are known for their durability, resistance to wear and tear, and unique natural patterns and colors. They are often used in high-end residential and commercial bathroom designs, as well as in outdoor spaces such as gardens and patios. Stone washbasins can be carved or shaped into a variety of different designs and sizes, and may be installed as a drop-in sink, undermount sink, or integrated sink. They are typically sealed to prevent staining and maintain their appearance over time.
