Using your POSEIDON ceramic basin is easy. Just mount it above the counter as per the instructions. You can purchase the 32mm pop - up waste separately and install it for proper drainage. When using, avoid dropping heavy objects into the basin to prevent cracks. For maintenance, clean it regularly with a mild soap and a soft cloth. Don't use abrasive cleaners as they can scratch the matte white finish. If there are any stains, soak a cloth in a mixture of water and vinegar and gently rub the area.
