How Much Are Bathroom Cabinets in Australia?
Most published bathroom cabinet prices are supply-only figures. The installed cost — once labour, plumbing connection, site modification, and waste disposal are factored in — is a different number entirely. Sometimes nearly three times the sticker price.
This guide covers what actually determines cabinet cost, realistic AUD ranges by cabinet type, and what a properly itemised quote should include. It doesn’t recommend specific products or brands. That’s not what it’s for.
The Variables That Actually Determine Cabinet Cost
Before any figure is useful, you need a model for what moves the price. Bathroom cabinet cost is driven by four independent variables — type, material and finish, size and configuration, and hardware. Change any one of them and the cost changes materially. The ranges in the next section only make sense once you understand why.
Cabinet Type — Flat-Pack, Semi-Custom, or Bespoke Joinery
These aren’t marketing categories. They describe fundamentally different products made to different tolerances, from different materials, by different supply chains.
Flat-pack means an MDF carcass, factory-cut to standard dimensions, packed unassembled and built on-site. The price is low because the manufacturing is high-volume and the assembly labour is yours. The trade-off is fixed dimensions, limited finish options, and a carcass that won’t accommodate site variations without modification.
Semi-custom or pre-assembled units come fully built, typically in a wider range of finishes, but still to fixed dimension increments. You’re paying for the assembly labour and a better finish range. The carcass is sturdier. The installation is faster. The supply price is higher.
Bespoke joinery is made-to-measure by a joiner or cabinet maker, to your specific dimensions and finish specification. Lead time is typically 4–12 weeks. The supply price is significantly higher — and the gap exists because every unit is produced once, not at scale. That premium is sometimes worth it and sometimes isn’t. The section on custom vs. flat-pack below covers when to make that call.
The supply price gap between a flat-pack vanity and a bespoke one for the same space can run from $300 to over $4,000. That’s not arbitrary. It reflects real differences in labour, material quality, and manufacturing volume.
Material and Finish
Bathroom cabinetry operates in a high-humidity environment. The substrate and finish combination matters — not just aesthetically, but structurally. Moisture infiltration at the carcass level accelerates deterioration and is one of the more common causes of premature cabinet failure in poorly ventilated bathrooms.
Moisture-resistant MDF with vinyl wrap — the most common flat-pack configuration. Performs adequately in well-ventilated bathrooms. Vulnerable to delamination at edges over time, particularly around the sink cut-out and at the toe kick. Lowest cost.
Moisture-resistant MDF with polyurethane — a step up. The polyurethane coating bonds more reliably to the substrate and resists humidity better than vinyl wrap in high-use bathrooms. Easier to repair than two-pack. Mid-range cost.
Two-pack polyurethane on MDF — the trade standard for semi-custom and bespoke joinery. Applied in two catalysed coats, it’s harder, more colour-stable, and more resistant to moisture penetration than single-stage poly. Costs more to apply and more to repair if damaged. Worth it in bathrooms that will be used heavily or held long-term.
Solid timber or veneer — less common in wet areas due to movement with humidity changes. When specified, it should be a considered decision, not a default. Higher cost, higher maintenance, and requires a joinery specialist rather than a standard cabinet supplier.
Size, Configuration, and Plumbing Alignment
Standard vanity widths in the Australian market run at 600mm, 750mm, 900mm, 1200mm, and 1500mm. Anything outside those increments means either bespoke manufacture (add cost) or on-site modification to a standard unit — also add cost, often more than people expect.
The plumbing alignment issue catches more homeowners than any other single variable. A cabinet that doesn’t sit over the existing waste and water rough-in positions requires either moving the rough-in (licenced plumber, significant cost) or cutting and modifying the cabinet carcass on-site (joinery labour, additional cost, and a voided manufacturer warranty if you’re using a flat-pack unit). Neither option appears on the supply price.
Double vanities and full wall units add a further consideration: structural fixing. A 1500mm double vanity loaded with products weighs considerably more than a 600mm single. The wall substrate needs to support that load. If it doesn’t — fibre cement sheeting over a poorly blocked stud wall, for example — that’s a rectification cost that needs to be scoped before the cabinet is ordered, not discovered on installation day.
Hardware
Most flat-pack and semi-custom cabinets are supplied with basic drawer runners and hinges. What basic means in practice: they work on day one, and you’ll be replacing them within five to eight years in a high-use bathroom. Soft-close mechanisms — hinges and drawer runners both — are rarely included at the entry price point. They’re specified and priced separately.
Adding quality soft-close runners and hinges to a single 750mm vanity typically adds $80–$180 to the supply cost. A full hardware upgrade for a 1500mm double vanity — soft-close runners, soft-close hinges, and pull hardware — can add $300–$500. Drawer runners are what homeowners interact with every morning for the next fifteen years. They fail first, they’re noticed immediately, and retrofitting them once the cabinet is installed is fiddly work that costs more than fitting them correctly from the start.
Indicative Bathroom Cabinet Costs in Australia — 2025/2026
The figures below are indicative industry estimates for the Australian market. They are not quotes. Actual costs depend on the supplier, finish selection, hardware specification, and site conditions. What they should do is give you a realistic frame of reference before you receive quotes — so you can tell the difference between a competitive price and one that’s left something out.
Supply cost — indicative ranges (AUD)
Installation and modification costs — indicative ranges (AUD)
The total installed cost for a flat-pack vanity in a standard, uncomplicated installation — cabinet, delivery, hardware not included in the pack, installation labour, and plumbing connection — typically lands between $500 and $1,200. A semi-custom unit installed with minor modification to the existing rough-in typically sits between $1,200 and $3,000 all-in. Metro vs. regional pricing variation exists but site condition moves the number more than location does.

The Installed Cost Gap — What the Supply Price Doesn’t Tell You
This is the section most homeowners skip. It’s also the reason so many renovation budgets blow out before anything else goes wrong.
Take a specific example. A 750mm flat-pack vanity unit from a bathroom tile and fixture supplier: $580. That’s the price on the website. That’s the price in the catalogue. That is not what it costs.
That rough-in offset — 40mm out from where the cabinet expects it — is not a worst-case scenario. It’s a normal finding in an existing bathroom where the new cabinet wasn’t specified against the original plumbing position. It’s the kind of thing that gets discovered on installation day, at which point the homeowner is already committed and has limited leverage to push back on the variation cost.
The cost items that most commonly disappear from verbal quotes and online price comparisons are: plumbing connection (often quoted separately by the plumber and not mentioned by the cabinet supplier), modification labour, and waste disposal. A quote that presents a single line reading “supply and install vanity — $780” tells you nothing about which of these are included and which will appear as a variation after the work starts. That’s not necessarily a dishonest quote. It may just be an incomplete one. The problem is you can’t tell the difference until it’s too late.

Custom Joinery vs. Flat-Pack — When the Price Difference Is Worth It
The $3,000 gap between a flat-pack vanity and a bespoke one is not always irrational. It’s also not always justified. The answer depends on the specific circumstances of the bathroom and the brief — not on a general preference for one over the other.
One framing worth applying before specifying custom joinery: if the property is an investment and the bespoke cabinet achieves the same rental yield as a well-chosen semi-custom one, the $2,500 price difference is a cost, not an investment. That’s not a reason to avoid custom joinery — it’s a reason to be clear about who it’s for and why. See our investment property renovation guide ›
What a Complete Bathroom Cabinet Quote Should Include
A quote that bundles supply and installation into a single figure makes it impossible to compare against another quote — or to identify what’s been excluded. Run every cabinet quote against this checklist before you accept it.
Cabinet supply — with full specification
Manufacturer or supplier name, model or product reference, dimensions (width × height × depth), substrate, and finish. “Vanity unit” is not a specification. If a quote doesn’t name the product with enough detail to order it independently, you can’t hold anyone to what was quoted.
Hardware — itemised separately
Drawer runners (type and whether soft-close), hinges (type and whether soft-close), handles or pull hardware. Confirm whether these are included in the supply price or quoted separately. Hardware omissions are the most common source of “it’s extra” conversations after a quote is accepted.
Delivery and handling
Who is responsible for site delivery, on which date, and who inspects the unit on arrival for damage. A cabinet that arrives damaged and has already been signed for is a problem that lands with the homeowner, not the supplier.
Installation labour — as a fixed or clearly estimated line
Fixed price or hours-based with a day rate — but stated. This line should cover assembly (for flat-pack), fixing to the wall, and levelling. Confirm whether this includes the basin installation or just the cabinet. These are often split across trades.
Plumbing connection — on a separate plumbing quote
The basin waste connection and tapware connection must be completed by a licenced plumber. This should appear on the plumber’s quote, not bundled into a joiner’s or builder’s line without being itemised. If it’s missing entirely, ask where it’s being accounted for before work starts.
Modification allowance
A contingency line for on-site cutting, scribing to the wall, or plumbing alignment adjustment. If a quote has no modification allowance, the question to ask is: what happens if there’s a rough-in offset or an out-of-square wall? If the answer is a variation on the day, at day-rate, you don’t have a fixed price — you have an estimate with an uncapped exposure.
Waste removal and disposal
Removal of the old cabinet, disposal to a licenced tip or waste facility, and cleaning of the installation area. If it’s not listed, it’s not included. A vanity carcass on your driveway at the end of installation day is not the outcome you were expecting from a complete job.
A quote that presents a single labour line without separating these items should prompt specific questions before you sign. A contractor who resists itemising them when asked is giving you information about how the job will be managed — not just how it will be quoted.

Common Questions About Bathroom Cabinet Costs
Questions that come up consistently when homeowners are researching cabinet costs before a renovation or refresh.
Neither is categorically cheaper. Online supply often carries a lower sticker price but excludes delivery, may arrive damaged with difficult return logistics, and can’t be inspected before purchase. A unit that arrives with a dented carcass or a mismatched finish, already signed for, is a problem that sits with you.
Showroom supply includes margin but allows you to confirm dimensions physically, inspect the finish in person, and talk to someone who can flag compatibility issues before the cabinet is ordered. For a standard, uncomplicated installation it may not matter much either way. For a bathroom with non-standard dimensions or an existing rough-in that needs to be assessed against the cabinet specification, the ability to have that conversation before purchase is worth something.
The more useful question isn’t online vs. showroom — it’s whether the supplier can provide a full specification sheet confirming substrate, finish type, internal dimensions, and hardware inclusions. That’s what your installer needs to confirm alignment and compatibility before the cabinet leaves the supplier.
Standard installation — cabinet fixing and levelling only, no plumbing connection, standard wall substrate — typically runs $150–$350. Add $180–$320 for basin waste and tapware connection by a licenced plumber. If the existing rough-in needs to be adjusted to align with the new cabinet, add $350–$700 depending on the extent of the plumbing work.
The total installed cost for a single vanity in an existing bathroom — including all labour, hardware, plumbing connection, and waste removal — typically lands between $500 and $1,200 for a flat-pack unit. A semi-custom unit with minor site modification typically sits between $1,200 and $3,000 all-in.
Site complexity is the variable that moves the number most. A bathroom with a clean rough-in, square walls, and a standard substrate is at the lower end. One that hasn’t been touched since the 1980s may not be.
Break the question down by trade type. The cabinet itself — fixing it to the wall, assembling the carcass, installing drawers and doors — is carpentry or joinery work. Licencing requirements for this vary by state, but in most cases a trade licence isn’t required for the cabinet work alone.
The plumbing connections require a licenced plumber in all Australian states, without exception. The tapware connection, basin waste connection, and any adjustment to the water supply rough-in must be completed by a licenced plumber. Electrical work — if the specification includes an integrated shaving cabinet with power, lighting, or an anti-fog mirror — requires a licenced electrician.
Attempting the plumbing or electrical connections without a licence is illegal, voids home insurance coverage for any related damage, and creates a liability that sits with the homeowner for as long as the work remains in place. The licence verification step takes minutes. Our NSW Fair Trading licensing guide explains how to check a contractor’s licence before work begins.
In Australian trade usage, a vanity unit is specifically the cabinet below or housing the basin — the primary storage unit in the wet area. It’s connected to the plumbing, it sits on or near the floor, and it’s the cabinet most commonly replaced in a bathroom renovation.
Bathroom cabinet is a broader term that covers shaving cabinets (wall-mounted above the basin, usually with a mirrored door), linen towers (tall storage columns, freestanding or wall-fixed), above-toilet storage units, and full wall cabinetry that spans an entire bathroom wall. Costs differ significantly across these types — a shaving cabinet runs $350–$900 supply, while a full bespoke wall unit can exceed $10,000.
Most of the cost conversation in this guide concerns the vanity unit, because it’s the most complex installation — plumbing connection required, highest modification risk, and the most commonly quoted item in a renovation scope.
Well-specified, moisture-resistant cabinetry in a properly waterproofed bathroom with adequate ventilation — an exhaust fan rated for the room volume, run long enough to clear humidity after use — should last 15–25 years before substrate degradation becomes a visible or structural problem.
The signs that replacement is overdue, rather than cosmetic: swelling or softening at the carcass base, which indicates moisture ingress at the substrate level rather than surface condensation; delamination of vinyl wrap or veneer at the edges, particularly around the sink cut-out; drawer runners that have failed structurally and can’t be re-adjusted; and visible mould inside the carcass that recurs despite cleaning.
One flag worth noting: if the cabinet base is swelling, the cause may be the floor waterproofing rather than the cabinet itself. Water wicking up through a failed wet area membrane will destroy a cabinet from the base up. Replacing the cabinet without investigating the waterproofing means replacing it again in a few years. Check the membrane before you order the new unit.
