Using this POSEIDON basin is easy. Just install it on your countertop as an above - counter basin. When using, make sure not to put overly sharp or heavy objects that could scratch or damage the copper interior or the black exterior. For maintenance, clean it regularly with a mild soap and a soft cloth. Avoid using abrasive cleaners as they can harm the surface finish. The pop - up waste, if you purchase it separately, should be installed according to the included instructions.
