Top-mount sinks are satisfactory for beautiful much any countertop material, including wood and laminate, as the cutout is unquestionably covered by the sink and hence does not risk physical damaged by water. They are also less expensive to install in a rock countertop, because they do not require laborious polishing of the cutout edges, as later an under-mount sink.
