Probably the most commonly used bathroom basin, a top mount, or ‘drop-in sink’, as the name suggests, is designed to sit on top of the bench.
Generally speaking, most of the basin sits below the benchtop, with just the rim of the basin sitting on top of, and visible above, the benchop. The rim can either be very slim or a bit chunkier like the one pictured, depending on the style you choose.
PROS: Top-mount basins are suitable with pretty much any benchtop material including timber and laminate, as the cut out is completely covered by the basin and therefore doesn’t risk being damaged by water. They are also less costly to install into a stone benchtop, because they don’t require laborious polishing of the cut out edges as with an under-mount basin.
CONS: You can’t wipe water and spills straight from the bench into the basin.
GOOD FOR: Elegant ensuites and minimast schemes.
