Inset Sinks Buying Guide


An inset sink is lowered into a cut-out in the benchtop from above, with its rim resting on the surface. It is also called a top mount, drop-in or overmount sink. This collection includes Phoenix stainless steel and quartz resin sinks, Turner Hastings Cuisine and Lusitano fireclay sinks, and Clark, Seima and Caroma stainless steel sinks. It is the practical choice for most renovations and for laminate or timber benchtops.

What is an inset sink?

An inset sink has a lip or rim that sits on top of the benchtop and covers the edge of the cut-out. It is held in place with clips underneath and sealed with silicone. Because the rim hides the cut, the cut-out does not need a polished edge, which makes the sink easy to fit and replace.

Inset or undermount: which should I choose?

Choose by benchtop. An inset sink suits laminate, timber and stone, because the rim protects the cut edge from water. An undermount sink sits below a stone or solid surface benchtop with no rim, so crumbs wipe straight in, but it is not suited to laminate or timber. Some sinks, such as the Turner Hastings Cuisine range, can be fitted either inset or undermount.

What size inset sink do I need?

Measure the base cabinet and any existing cut-out. Inset sinks in this range go from compact single bowls, such as the Turner Hastings Cuisine 30 x 46, to large double bowl sinks with drainers, such as the Phoenix 1000 Series 1180 x 500mm and the Turner Hastings Lusitano 120 x 50. Each sink lists its overall size and cut-out size; the cut-out must suit the cabinet below.

Can I replace an inset sink without a new benchtop?

Often, yes. If the new sink's cut-out is the same size or slightly larger than the old one, it can go into the existing benchtop. A larger cut-out can be made on laminate and timber. If the new cut-out is smaller than the old hole, the rim will not cover it, so measure the existing hole carefully before you choose.

Do inset sinks come with a drainer?

Some do. Sinks such as the Seima Acero Classic double drainer and the Turner Hastings Lusitano double sink with drainer have a built-in draining area. A drainer gives you somewhere to stand wet dishes without a separate rack. Single bowl sinks without a drainer, such as the Seima Tetra Pro, save bench space.

Which inset sink material is best for me?

Stainless steel, such as the Phoenix 2000 Series or Clark Monaco, is durable, hygienic and easy to clean. Quartz resin, like the Phoenix 5000 Series in matte white or matte black, resists scratches and gives a solid colour. Fine fireclay, such as the Turner Hastings Cuisine, has a hard glazed finish and a classic look. Clean any sink with mild detergent and a soft cloth.

Frequently Asked Questions

What is an inset sink?

An inset sink is another name for a drop-in or top-mount sink, it sits into a cutout in the benchtop with its rim resting on the surface, rather than being fixed underneath. The term "inset" is used interchangeably with "drop-in" and "top-mount" across the industry, they all describe the same rim-on-benchtop mounting method. For a full rundown of how this mounting style works, see drop-in kitchen sinks.

What's the difference between an inset and an undermount sink?

An inset sink's rim sits visibly on top of the benchtop around the cutout, while an undermount sink is fixed underneath the benchtop so the stone or solid surface finishes cleanly at the edge of the bowl with no visible rim. The practical difference that matters most when choosing between them is benchtop material: an inset sink works with almost any benchtop, including laminate, timber and stone, because the rim covers the cut edge, while an undermount sink needs a stone or solid-surface benchtop with a finished edge, since there's no rim to hide an unsealed laminate cutout.

Can an inset sink be fitted to a laminate benchtop?

Yes, and this is one of the main reasons to choose an inset sink over an undermount one. Because the rim sits on top of the benchtop rather than requiring a sealed, finished cut edge, an inset sink works with laminate, timber, stone or any other common benchtop material. An undermount sink, by contrast, isn't a practical option on laminate, since the exposed particleboard edge underneath would be left unsealed and prone to water damage.

Can you replace an inset sink without replacing the whole benchtop?

Usually yes, provided the new sink's external dimensions and cutout size are the same as, or close to, the one being replaced. If the new sink is a different size or shape, the benchtop cutout may need to be re-cut or, on laminate, patched, so it's worth confirming external dimensions against the existing cutout before ordering. A licensed plumber should handle disconnecting and reconnecting the tap and waste during the swap.

What are the three main types of kitchen sink?

The three common mounting types are inset (also called drop-in or top-mount, rim rests on the benchtop), undermount (fixed below the benchtop for a flush finish), and integrated or moulded-in sinks, which are formed as part of a solid-surface benchtop with no separate rim or seam at all. Inset is generally the most flexible on benchtop material, undermount is the more common choice for stone benchtops, and integrated sinks are the least common due to cost and being locked to one specific benchtop material.

Does an inset sink cost less to install than an undermount sink?

Generally yes, since fitting doesn't require the same precision-finished cutout edge that an undermount installation needs, and the visible rim covers any minor inconsistencies in the cut. This makes inset a common choice for straightforward replacements and benchtops where a perfectly finished edge isn't practical, such as laminate.
