Bathroom vanity installation in Australia typically costs A$250–A$900 in labour when you supply the unit. The variance comes from three things: whether the plumbing lines up, whether the wall is sound, and whether the job needs a licensed plumber, a carpenter, or both.
Labour cost breakdown
| Task | Typical cost (AUD) | Who does it |
|---|---|---|
| Remove and dispose of old vanity | $75 – $250 | Handyperson |
| Disconnect and reconnect plumbing | $150 – $450 | Licensed plumber |
| Secure cabinet to wall or floor | $120 – $350 | Carpenter / handyperson |
| Cut and fit stone top | $200 – $600 | Stone mason |
| Tile or plaster repair | $250 – $800 | Tiler / plasterer |
| Electrical (shaver point, lighting) | $150 – $500 | Licensed electrician |
When installation is simple
A same-size swap in a room where the shut-off valves turn freely, the wall studs are where they should be, and the waste is centred is a two-to-three-hour job. In that case A$250–$500 covers it, and the plumber’s portion is short.
When it becomes a bigger job
Four conditions turn a simple install into a half-day or more:
- Wall-hung unit replacing a floor-standing one. Requires framing inside the wall or a fixing system rated for the load, plus relocating the waste into the wall cavity.
- Different width. The old footprint leaves a gap or an overlap; tiles and plasterboard need patching and the finish needs to match.
- Corroded valves. Old gate valves often fail when turned after years of disuse, which means shutting off the water at the mains and replacing them.
- Offset waste. A new vanity with a centred waste will not connect to an existing offset drain without modification.
Who you need to hire
In Australia, sanitary plumbing work — connecting the waste outlet and water supply — must be done by a licensed plumber. Cabinet fixing, cutting the top and general carpentry can be done by a carpenter or competent handyperson. Electrical work requires a licensed electrician. Doing plumbing yourself may void insurance and creates a compliance problem at sale.
What a fair quote looks like
- Separate line items for removal, plumbing, cabinet fixing and disposal
- Confirmation of whether the top is included and who installs it
- Statement of what happens if the wall or floor needs repair
- Licence numbers for plumbing and electrical
- Call-out fee stated separately from hourly rate
Supply-and-install versus labour-only
Bundled supply-and-install from a bathroom retailer is convenient and usually priced at A$900–$2,000 for a stock unit. Labour-only is cheaper if you can source the vanity at trade or sale price, but you carry the risk of a sizing error. If you go labour-only, confirm the plumber is willing to work with a customer-supplied unit before it is delivered.
Preparation that reduces the bill
Clear the room, remove mirrors and shelves, and confirm the water shut-off works before the trades arrive. Have the new vanity on site and unpacked, with the top and tapware present. Every return visit for a missing part is billable time.
Cost by city
Sydney and Melbourne plumbers typically charge A$120–$180 per hour with a call-out fee; Brisbane and Perth are broadly similar; regional areas may charge lower hourly rates but add travel. For a small job, the call-out fee can be a third of the invoice, so bundling other plumbing work into the same visit reduces the effective cost.
Timeline and scheduling
A straightforward swap is a single visit: removal, plumbing disconnect, cabinet fixing, reconnect and test. Where patching or a new top is required, plan two visits across two days so adhesives and silicone can cure. If the vanity is a different width, add a tiler or plasterer, which usually means a third visit and a week of elapsed time between them.
Book the plumber first. In most Australian capitals, licensed plumbers are the constraint in the schedule, not the cabinet supplier. Order the vanity only after the plumber has confirmed the waste and water positions.
Compliance checklist before sign-off
- Waste connection tested for leaks under running water, not just visual check
- Water supply isolated and re-opened with no weeping at the compression fittings
- Cabinet fixed into studs or a rated fixing system, not plasterboard anchors alone
- Silicone lines continuous at the wall-floor junction and around the basin
- Electrical work certified if lighting or a shaver point was added
- Old unit removed from site, not left in the garden
Replace the vanity or renovate the bathroom?
If the tiles, waterproofing and shower are sound, replacing the vanity alone is a sensible spend. If the shower leaks, the floor wastes are corroded, or the room has not been touched in 25 years, a vanity swap often becomes the trigger for a full renovation — and doing them separately costs more than doing them together, because the room is demolished twice.
A useful test: check for movement or swelling at the base of the cabinet, staining on the ceiling below, and whether the silicone lines fail within months of replacement. Any of those point to a moisture problem that a new vanity will not solve.
When the wall is not square
Older Australian bathrooms rarely have plumb walls or level floors. A vanity fitted to an out-of-square wall leaves a visible taper at one end, which is why installers scribe a filler panel rather than forcing the cabinet. Budget A$80–$250 for a scribe or filler if the wall deviates by more than about 10 mm over the cabinet width. If the deviation is larger, the better fix is to straighten the wall with a stud pack before the cabinet goes on — cheaper than a custom-shaped vanity.
Check with a spirit level across the proposed top line and down both corners before ordering. Photograph the measurements; suppliers will ask.
FAQ
How much does a plumber charge to install a vanity?
Usually A$150–$450 for disconnect, reconnect and testing, assuming the connections are accessible and the layout matches. Wall-hung units and relocated wastes cost more.
Can a handyperson install a vanity?
They can fix the cabinet and fit the top. They cannot legally connect the plumbing in Australia, so a plumber is still required for that portion.
Do I need a new vanity if only the top is damaged?
No. Replacing just the top costs A$250–$900 installed, provided the carcass is sound and the size is standard.
How long should installation take?
Two to four hours for a same-size stock unit. Half a day to a full day if patching, plumbing changes or wall framing are involved.

Labour ranges are 2026 planning estimates based on published Australian trade rate guides and typical metropolitan call-out structures. They exclude the cost of the vanity itself and exclude GST where quoted separately. They are not quotes.
