Prime-Line Lavatory Sink Porcelain 19 in. Round Self Rimming 4 in. Centers Front (Single Pack) MP52100

These drop in lavatory sinks are easy to install as they simply drop into a cutout on the countertop and are held in place using silicon caulk. Total diameter including the rim is 19 inch, so the cutout must be slightly smaller than that to allow for proper contact. Replacing an old sink is a quick and affordable way to improve the appearance of your bathroom.
