To use this vintage Turkish marble sink, simply install it in your bathroom as you would a regular sink. Connect the plumbing and start using it for washing hands, face, etc. When it comes to maintenance, use a mild soap and a soft cloth to clean the marble surface regularly. Avoid using abrasive cleaners as they can scratch the marble. Also, try to wipe up any spills immediately to prevent stains. And be careful not to drop heavy objects on it, as the marble can crack.
