To use this basin, simply install it on your countertop as it is designed for above - counter mounting. When you need to drain water, operate the 32mm pop - up waste (which you'll need to buy separately). For maintenance, use a mild cleaner to wipe the matte white ceramic surface. Avoid using abrasive materials that could scratch the finish. Also, be careful not to drop heavy objects into the basin as it may cause cracks. Keep the basin dry when not in use to prevent the growth of mold and mildew.
