To use this sink, simply place it in your bathroom vanity as you would with any other sink. Connect the water supply and drainage pipes properly. When using, avoid using abrasive cleaners as they can scratch the marble surface. To clean it, use a mild soap and a soft cloth. Wipe it dry after each use to prevent water spots. Periodically, you can apply a marble sealer to keep it looking its best and protect it from stains. Be gentle when handling items near the sink to avoid causing further chips or cracks.
