Under-mount bathroom sink
An under-mount bathroom sink, as the name suggests, is a sink that is mounted underneath a countertop in the bathroom. Drop-in sinks are mounted to the top of the counter top.
The “hidden” edge of the best undermount bathroom sink has an attractive, streamlined appearance, and the lack of crevice or a lip makes the edges less likely to catch dirt.
Popular materials for white undermount bathroom sink include ceramic, porcelain and cast iron, and they can come in rectangular undermount bathroom sink and oval undermount bathroom sink.
Porcelain undermount bathroom sinks are recommended for granite, solid surface and quartz countertops, but may not be as effective with laminate. They can be more expensive than drop-in sinks.
