A double kitchen sink is a sink unit for kitchens that has two basins side by side — typically of equal or slightly varied sizes — allowing you to multitask while washing, rinsing and preparing food. In simple terms, it’s like having two sinks in one, giving you separate spaces for dishes and food prep or for soaking pans while you still have a basin free.
Here’s why Australians love a double kitchen sink: the main reason is that it boosts kitchen efficiency and organisation. Whether you’re cooking family meals, cleaning up after guests, or managing a busy household, a double basin setup allows you to separate tasks — for example, washing on one side and rinsing on the other — without switching tools or interrupting workflow.
Double kitchen sinks come in a variety of styles suited to different kitchen layouts, budgets and design trends across Australia:
Top‑Mount (Drop‑In) Double Sink
Installed by dropping into a cut‑out in the countertop.
Easiest for DIY installations and often more affordable.
Undermount Double Sink
Mounted beneath the benchtop for a flush, seamless look.
Gives a sleek, modern finish and makes cleaning benchtops easy.
Equal‑Sized Double Basins
Both basins are the same size, offering balanced workspace.
Great for symmetrical installations.
Double Sink with One Large, One Small Basin
One basin is larger for pots and pans, while the smaller is ideal for rinsing or prep.
Adds functional versatility.
Stainless Steel Double Sinks
Durable, hygienic and easy to clean — a classic favourite in many Aussie kitchens.
Ceramic or Fireclay Double Sinks
Heavier, premium look with a timeless aesthetic.
Often paired with country or heritage kitchen schemes.
Integrated & Seamless Double Sinks
Made from the same material as the benchtop (e.g., engineered stone) for a cohesive look.
From traditional farmhouse kitchens to sleek contemporary designs, these double kitchen sink types adapt to Australian homes of all styles and sizes.
Choosing the right double kitchen sink involves balancing practical needs, space constraints and aesthetic goals. Here’s a practical buyer’s guide for Australians:
Measure Your Space
Check your bench depth and width. A typical double kitchen sink requires at least 760–900 mm width, but always confirm your cabinet size.
Consider Basin Sizes
If you frequently wash large pots or baking trays, a larger left basin with a smaller right basin can help with multitasking.
Material Matters
Stainless Steel: Durable, affordable, and easy to maintain.
Ceramic/Fireclay: Scratch‑resistant, classic look, but heavier and requires sturdy support.
Granite/Composite: Robust, modern and resistant to stains and chips.
Tap and Accessory Compatibility
Ensure there are provisions for your preferred mixer tap, soap dispenser or filtered water tap.
Mounting Preference
Choose top‑mount for straightforward installation or undermount for a seamless contemporary finish.
Drainboard Integration
Some sinks offer built‑in drainboards or optional accessories, which are especially handy for busy kitchens.
Maintenance & Cleaning
Smooth surfaces and rounded corners make cleaning easier, especially for stainless steel.
By carefully considering these factors, you’ll choose a double kitchen sink that doesn’t just look great — it works beautifully with your day‑to‑day kitchen routine.
A double kitchen sink is a cornerstone of functional kitchens. Here’s why Australians invest in them and how they improve everyday home life:
Efficient Multitasking
Wash and rinse simultaneously — for example, soak greasy pans in one basin while prepping vegetables in the other.
Hygiene Separation
Separates food prep from dishwashing, reducing cross‑contamination.
Ideal for Busy Households
Makes hosting, cooking and cleanup easier, especially with kids or large family dinners.
Flexible Work Zones
Use one side for washing and the other for drying with a drainer rack.
Enhanced Kitchen Workflow
Keeps tasks organised, which is crucial during meal prep and cleanup marathons.
Pet Feeding & Cleaning Uses
Many owners use one basin for rinsing pet bowls or washing produce without interrupting main kitchen tasks.
In simple terms, the main reason Australians love double kitchen sinks is their functional versatility — they make cooking and cleaning smoother, quicker and more organised.

Extra‑Deep Basins

A double kitchen sink isn’t just about utility — it’s a design opportunity. Here’s how to style it within your Australian kitchen:
Coordinate with Taps
– Match your sink finish (e.g., brushed stainless or matte black) with kitchen mixer taps for a cohesive look.
Use Countertop Accessories
– A sleek dish rack, integrated soap dispenser or minimalist drying mat keeps the workspace tidy and intentional.
Balance with Backsplash & Benchtop
– Contrast your sink with light stone or timber benches to create visual depth.
Introduce Greenery
– Place a small plant nearby to soften the look and inject life into your kitchen zone.
Keep Clean Lines
– Use undermount sinks and hidden drains to maintain a seamless surface, especially in open‑plan kitchens.
Functional Décor
