The single most common reason a smart sink purchase goes wrong in Australia is cabinet width, since workstation sinks are noticeably wider than the standard bowls most kitchens were built around. Beyond that, the decisions that matter are material grade and gauge, which accessories actually come in the box, whether the model needs a power supply, and what the benchtop cutting will cost on a stone or engineered surface. This guide works through each consideration in the order a buyer needs them, so the shortlist gets narrowed by what will actually fit and function before it gets narrowed by looks.
Key Takeaways
- Cabinet width is the first thing to measure, since workstation sinks are wider than standard bowls and cannot be fitted into an undersized cabinet without joinery work.
- Material grade and gauge are separate specifications, and a thicker body resists denting and dampens noise while grade governs corrosion resistance.
- Accessories vary considerably between models, so confirming exactly what is included avoids buying a sink and then buying the boards and racks separately.
- Some smart sinks need a power supply for digital displays or electronic functions, which adds an electrician to the installation where no powerpoint exists nearby.
- Alia Global's Smart Sink is 1050mm wide, custom-made from 3mm stainless steel with a PVD protective surface, and priced at $2,600.
Start With Cabinet Width and Sink Dimensions
Measuring the base cabinet before shortlisting any model is the step that saves the most money, because it rules out options that would otherwise need joinery work to accommodate. A workstation sink needs a cabinet wider than the sink itself, with clearance on both sides for the benchtop cutout and the mounting.
Alia's Smart Sink measures 1050mm wide, which suits a cabinet sized accordingly. Many Australian kitchens are built around 600mm or 900mm base cabinets, so a wider workstation sink often means either reworking the cabinetry or choosing a narrower model.
Depth matters too, both bowl depth and front-to-back dimension. A deeper bowl holds more and hides dishes better, though it also sits lower relative to the waste and needs adequate clearance underneath for the trap and any under-sink equipment already installed.
Check What the Benchtop Cutting Will Cost
The sink is only part of the cost. Cutting a benchtop to fit it is a separate job, and the price varies enormously by material.
- Laminate is the cheapest to cut and can often be done on site
- Stone, granite, porcelain and engineered surfaces require a specialist with a diamond core bit, charged separately from the plumbing
- Timber sits in between, though it needs careful sealing around the cutout to prevent water damage
- Replacing an existing sink with one of different dimensions almost always means a new cutout, since enlarging an existing one is rarely straightforward
Getting a quotation for the cutting before committing to a model avoids a common surprise, particularly where a wider workstation sink means cutting into an existing stone benchtop.
Understand Material, Grade and Gauge
Most smart sinks are stainless steel, but that description covers a wide range of actual build quality.
Gauge refers to the thickness of the steel. A thicker body resists denting, dampens the noise of running water and stacked dishes, and feels considerably more solid in daily use. Alia's Smart Sink is custom-made from 3mm stainless steel, precision laser cut and hand welded, which is substantially heavier than the thin-gauge pressed construction common at the budget end of the market.
Grade is a separate specification, referring to the alloy composition, and it governs corrosion resistance while gauge governs rigidity. A surface treatment such as a PVD, or Physical Vapour Deposition, coating adds a further layer of scratch, stain and corrosion resistance over the base steel. Both are worth checking on the specification sheet, since neither is visible from a product photograph.
Confirm Exactly Which Accessories Are Included
Accessory inclusion varies more between brands than almost any other aspect of the category, and it materially changes the real cost of a purchase.
Common workstation accessories include a cutting board sized to the ledge, a colander, a drying rack, a bottom grid to protect the base, and a strainer. Consumable items that need periodic replacement, such as an F5000L filter cartridge where the sink is paired with a filtered tap, are a separate ongoing consideration from the accessories supplied in the box. Some manufacturers include all of these, others include one or two and sell the rest separately, and a few include none at all.
Alia's Smart Sink is supplied with multifunctional accessories alongside its integrated mixer tap. Confirming the exact list against the current product listing before ordering is worth doing, since accessory inclusions can change between production runs. Our guide on smart sink vs traditional sink covers how much of the value case rests on these accessories being included.
Work Out Whether You Need a Power Supply
Not every smart sink needs electricity, and this is worth establishing early.
Basic workstation sinks, where the intelligence is purely in the ledge design and accessories, need no power at all and install exactly like a conventional sink. Models with digital temperature displays, touch controls or electronic functions do require a supply, which means a licensed electrician where no suitable powerpoint exists in the cabinet below.
Alia's Smart Sink includes a digital display showing water temperature directly at the sink, alongside a high-pressure cup washer and waterfall rinse area, so the installation should account for this. Checking the specific model's requirements against the cabinet's existing services before ordering avoids an unwelcome addition to the installation bill.
Check Your Water Pressure and Flow
Integrated functions such as a high-pressure cup washer and a dedicated rinse outlet draw more from the water supply than a standard tap, so pressure and flow rate both matter.
Most Australian properties are supplied between 200 kPa and 500 kPa, with the national plumbing standard capping maximum operating pressure inside a building at 500 kPa. Properties at the low end of that range, typically those on higher ground or at the end of a long supply line, may find integrated functions perform below expectations without a booster pump.
A licensed plumber can take a pressure reading at the property as part of a pre-installation check, which is a short job that avoids a disappointing result after installation.
Think About How the Sink Pairs With Your Tap
A smart sink and the tap above it need to work together, both visually and practically. Some workstation sinks come with an integrated mixer, while others are supplied as the bowl only, leaving the tap as a separate purchase and a separate decision.
Where the tap is separate, spout height and reach matter more than usual, since a workstation sink is wider and deeper than a standard bowl. A spout that clears a standard sink comfortably may sit awkwardly over a larger workstation bowl.
Many households specifying a smart sink also consider a multi-function tap at the same time, since both consolidate kitchen functions and reduce bench clutter. Our guide on types of kitchen water taps sets out the options, and Alia's instant boiling water tap range covers the configurations available. Specifying both during the same renovation is considerably cheaper than adding the second later.
Factor In Local Water Conditions
Water hardness affects how a stainless steel sink looks day to day, regardless of its grade or finish. Harder water leaves more visible spotting and mineral film on the surface, which means more frequent wiping to keep the sink looking its best.
This varies significantly across Australia, from Melbourne and Sydney's soft supplies through to Adelaide, parts of Perth and bore-fed regional areas where hardness is considerably higher. Our guide on hard water vs soft water sets out where each capital sits.
None of this should rule out a smart sink in a harder water area. It simply sets realistic expectations about cleaning frequency, and it makes a smoother finish with fewer crevices a more practical choice in those regions.
Set a Realistic Total Budget
The sink price is the headline figure, but the total cost of getting a smart sink installed and working includes several other items.
- The sink itself, plus any accessories not included in the box
- Benchtop cutting, particularly on stone or engineered surfaces
- Plumbing labour for the installation and waste connection
- Electrical work where a powerpoint is needed and none exists nearby
- Cabinetry modification where the existing base cabinet is too narrow
- A tap, where the sink is supplied without an integrated mixer
Installation labour rates vary by state, by trade and by the complexity of the specific kitchen, so a quotation on inspection is the only reliable figure for those elements.
Why Alia Global's Smart Sink Is Built to Be Specified Properly
Alia's Smart Sink is priced at $2,600 and custom-made from premium 3mm stainless steel, precision laser cut and hand welded to create a substantial, carefully finished kitchen workstation with the character of a custom-made product. A high-quality PVD protective surface sits over the base steel, adding resistance to scratches, stains and everyday corrosion while keeping maintenance straightforward.
At 1050mm wide it combines dual sink spaces with a dedicated waterfall rinse area, a 360 degree pull-out mixer with a progressive mixer cartridge for precise temperature and flow control, a high-pressure cup washer for glasses and bottles, an integrated soap dispenser and a digital temperature display at the sink. Integrated overflow features help manage excess water during heavier use.
Published dimensions matter as much as the feature list, since they are what let a cabinetmaker and plumber confirm suitability before anything is ordered. The same approach extends across Alia's range, including the instant hot and cold water tap systems designed to pair with it and the X51 instant boiling, chilled and sparkling filtered water tap.

Frequently Asked Questions
What size cabinet do I need for a smart sink?
The base cabinet needs to be wider than the sink itself, with clearance for the cutout and mounting on both sides. Alia's Smart Sink is 1050mm wide, so the cabinet should be sized accordingly. Measuring the existing cabinet is the first step before shortlisting any model.
Do all smart sinks need electricity?
No. Basic workstation sinks need no power at all, while models with digital displays, touch controls or electronic functions do. Checking the specific model's specification sheet before ordering establishes whether an electrician needs to be part of the installation.
What accessories should come with a smart sink?
Common inclusions are a cutting board sized to the ledge, a colander, a drying rack, a bottom grid and a strainer, though inclusion varies considerably between brands. Confirming the exact list against the current product listing avoids assuming items that are sold separately.
Can a smart sink be fitted into an existing benchtop?
Often yes, though a workstation sink of different dimensions to the existing one generally requires a new cutout. On stone, granite or engineered surfaces this needs a specialist with a diamond core bit and is quoted separately from the plumbing.
How thick should a stainless steel smart sink be?
Thicker gauge material resists denting better and dampens noise from running water and dishes more effectively. Alia's Smart Sink uses 3mm stainless steel, which is substantially heavier than the thin-gauge pressed construction common at the budget end of the market.
