Double Bowl Kitchen Sink Buying Guide

A double bowl kitchen sink gives you two working zones: one bowl to wash in and one to rinse, soak or keep clear. This collection includes double, 1.75 and double-with-drainer sinks from Caroma, Clark and Fienza, in stainless steel, PVD finishes such as gunmetal, brushed brass, carbon metal and rugged brass, and fireclay in the Fienza Charlton double butler sink.

Is a double bowl sink worth it?

A double bowl suits households that wash dishes by hand, families or couples who cook together, and anyone who likes to keep dirty and clean dishes apart. If most of your washing goes in the dishwasher, a large single bowl may be more useful, because baking trays and large pots often will not lie flat in either half of a double sink.

What size double sink do I need?

A standard double bowl sink is about 760mm wide, such as the Fienza Hana 760 x 450mm with two 27 litre bowls, which suits a 900mm base cabinet. Larger options include the Fienza Hana 892mm with a 40 litre and 27 litre bowl, and sinks with a drainer such as the Fienza Hana and Tiva at 1180mm. Compare the inside bowl width with the largest items you wash, and check the cut-out against your cabinet.

Equal bowls or one large and one small?

Equal bowls give a clean split between washing and rinsing. An offset layout, with one large and one smaller bowl, gives you a main bowl big enough for larger items plus a prep or rinse bowl. The Fienza Hana 30L-15L and Fienza Tiva 670 are offset doubles, and the Caroma Luna 1.75 and Urbane II 1.75 bowl sinks take a similar approach. See 1.75 bowl kitchen sinks.

Do I need a double sink with a drainer?

A drainer gives you a built-in place to stand wet dishes and drains water back into the sink. It suits kitchens without a dishwasher or with long benches. The Fienza Tiva 1180 and Fienza Hana 1180 include a drainer, and the round corner double bowl sink is available with a left or right drainer. If bench space is tight, a sink without a drainer plus a sink grid may suit better.

Can a double bowl sink be undermounted?

Many can. The Fienza Hana range can be fitted top mount or undermount, and the Clark Polar and Prism double bowl sinks are listed for undermount or overmount. The Clark Monaco double bowl is an undermount sink. Undermount suits stone and solid surface benchtops; top mount suits laminate and timber.

Is there a double sink for outdoor kitchens?

Yes. The Caroma Compass Alfresco double bowl sink is made from 316 marine grade stainless steel for outdoor and coastal kitchens, and comes with accessories. Grade 316 resists salt air better than standard 304 stainless steel.

Completing the room

A double bowl sink needs a waste for each bowl, so see sink wastes. Add a pull out sink mixer that can reach both bowls, and compare stainless steel sinks.

Frequently Asked Questions

Is it worth getting a double bowl kitchen sink?

It depends on how you use the kitchen. A double bowl lets you soak or drain dishes in one side while washing or prepping in the other, which is genuinely useful if you cook often or don't run a dishwasher for every load. If most washing goes straight into a dishwasher, a single bowl with more uninterrupted width can be more practical for handling large pots, trays, and oven racks.

What do you call a sink with two bowls?

It's usually called a double bowl kitchen sink, sometimes a 1.5 bowl sink if the second bowl is noticeably smaller than the main one. A 1.5 bowl configuration is a middle ground: a full-size main bowl plus a smaller second bowl or integrated drainer, useful when you want the double-bowl workflow without giving up as much room in the main bowl.

Do double bowl sinks need two drains?

Yes, each bowl has its own waste outlet and trap connection, though both usually tie into a single drain line under the cabinet via a T-fitting. This is a standard plumbing configuration, but it does mean a double bowl sink needs more room under the cabinet for pipework than a single bowl, so check clearance around any cabinet shelving or a garbage disposal unit if one is fitted. A licensed plumber should handle the connection to keep it compliant.

What is a double bowl sink actually useful for?

The classic use is prepping vegetables or rinsing produce in one bowl while the other holds soaking pots or a drying rack. It also suits households handwashing delicate items separately from general dishes, or using one side purely for filling pots and kettles. If bench space is tight, a double bowl does take up more width than a single bowl of similar washing capacity, which is worth weighing against how often you'd actually use both sides at once.

Are the two bowls in a double bowl sink always the same size?

No. An even split (roughly equal bowls) suits households that wash and soak in similar volumes. An offset split, one larger main bowl and one smaller secondary bowl, suits those who want a big bowl for pots and trays but still like having a second smaller basin for rinsing or drainer use. Check the specific bowl dimensions rather than assuming "double bowl" means equal halves.

What size cabinet does a double bowl sink need?

Most double bowl sinks start around 700mm wide and run up to 900mm or more, so they generally need a base cabinet of at least 800mm to give clearance on both sides. If your cabinet run is narrower than that, a single bowl or a compact 1.5 bowl sink from the broader kitchen sinks range will fit more comfortably than forcing a full double bowl into a tight space.
