Vanity installation in New Zealand typically costs NZ$250–$850 in labour when you supply the unit. The variables are the same three as everywhere: whether the plumbing matches, whether the wall or floor needs repair, and whether the job needs one trade or two.
Labour breakdown
| Task | Typical cost (NZD) | Who does it |
|---|---|---|
| Remove and dispose of old vanity | $60 – $220 | Handyperson |
| Disconnect and reconnect plumbing | $150 – $400 | Licensed plumber |
| Secure cabinet to wall or floor | $120 – $350 | Carpenter / handyperson |
| Cut and fit stone top | $180 – $550 | Stone fabricator |
| Tile or plaster repair | $250 – $700 | Tiler / plasterer |
| Electrical (lighting, shaver point) | $150 – $450 | Licensed electrician |
When it is a simple job
A same-size swap where the shut-off valves work, the wall framing is where it should be and the waste is centred takes two to three hours. At that level, NZ$250–$450 covers the labour and the plumber’s attendance is short.
When it becomes a bigger job
- Wall-hung replacing floor-standing. Needs framing or a rated fixing system, plus moving the waste into the wall.
- Different width. Leaves a gap or overlap that requires tiling and plasterboard repair.
- Seized valves. Old valves often fail when turned, requiring the water to be shut at the mains and the valves replaced.
- Offset waste. A centred-waste vanity will not connect to an offset drain without modification.
Who must do the work
In New Zealand, sanitary plumbing must be carried out by a licensed plumber. Cabinet fixing and carpentry can be done by a builder or competent handyperson, and electrical work requires a registered electrician. Doing plumbing yourself risks insurance validity and creates problems when the house is sold.
What a fair quote looks like
- Removal, plumbing, fixing and disposal as separate lines
- Statement of whether the top is included and who installs it
- What happens if the wall or floor needs repair
- Licence or registration numbers for plumbing and electrical
- Call-out fee stated separately from the hourly rate
Supply-and-install versus labour-only
Bundled supply-and-install from a bathroom retailer usually costs NZ$750–$1,900 for a stock unit and removes the sizing risk. Labour-only is cheaper if you source the vanity at trade price, but you carry the risk of a wrong measurement. Confirm the plumber will work with a customer-supplied unit before it is delivered.
Preparation that reduces the bill
Clear the room, remove mirrors and shelves, confirm the water shut-off works, and have the vanity on site and unpacked with the top and tapware present. Return visits for missing parts are billable.
Cost by city
Auckland and Wellington plumbers typically charge at the top of the range, with call-out fees that can be a third of a small invoice. Christchurch and Hamilton sit mid-range. In smaller towns, hourly rates may be lower but travel and lead times add cost. Bundling other plumbing work into the same visit reduces the effective rate.
What to check at handover
Run the tap and check for weeping at the compression fittings, confirm the waste drains without gurgling, check the silicone lines are continuous, and make sure the cabinet is fixed into studs rather than plasterboard anchors. Photograph the connections before the room is put back together.
Timeline and how the visits break down
A simple swap is one visit. A swap with patching is two visits across two days so adhesive and silicone can cure. A wall-hung conversion or a relocated waste is three: plumber rough-in, carpenter and tiler, then plumber fit-off. Plan the sequence before ordering the vanity, because the cabinet has to be on site for the first plumbing visit in most cases.
Compliance and paperwork
Ask for the plumber’s registration number and, at completion, certification for the sanitary work. If electrical work was done, ask for the electrical certificate. Keep both with your property documents; they matter at sale and if an insurance claim is ever made for water damage.
Working with the plumber
Send photographs of the existing plumbing when requesting a quote, including the waste position and the supply points. Confirm whether the quote includes removal of the old unit and disposal. Ask what the call-out fee covers and whether a second attendance for fit-off is charged separately. These three questions prevent most invoice surprises.
What commonly goes wrong
The three most frequent problems are a vanity ordered 50 mm too wide, a waste that does not align with the cabinet cut-out, and a wall that cannot take a wall-hung fixing without additional framing. All three are detectable before purchase with a tape measure and a photograph, and all three cost several hundred dollars to fix afterwards.
Doing the prep yourself
Removing the old vanity, clearing the room and disposing of the unit are tasks a homeowner can do. That alone can reduce the labour bill by NZ$150–$350. Leave the disconnection to the plumber, and do not remove the old unit until the new one is on site and checked against the opening.
When the whole bathroom should be done instead
If the shower is leaking, the floor is drummy, or the room has not been touched in 25 years, replacing the vanity alone puts new joinery into a wet environment that is already failing. Ask a tiler to tap-test the floor and check the shower hob before spending on a vanity. Where two or three elements are near the end of their life, one renovation costs less than two separate projects and produces a better result.
FAQ
How much does a plumber charge to install a vanity in NZ?
Usually NZ$150–$400 for disconnect, reconnect and testing at existing positions. Wall-hung units and relocated wastes cost more.
Can a handyperson install a vanity?
They can fix the cabinet and fit the top. Plumbing connections must be done by a licensed plumber.
Do I need a new vanity if only the top is damaged?
No. Replacing the top alone costs NZ$250–$800 installed if 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 or plumbing changes are involved.
