By the GetListed team · Updated 20 October 2026 · 8 min read

Published New Zealand guides mostly put a full bathroom renovation at about $20,000 to $45,000 in 2026. A cosmetic refresh can cost from roughly $5,000 to $15,000, and high-end rebuilds with wet-room showers and premium finishes run to $65,000 or more. These are indicative figures from Canstar, Trade Me and renovation companies, and real quotes vary with your home, region and scope.

The biggest swing factors are whether plumbing moves, whether the shower is tiled, and what is hiding behind the walls. This guide shows the ranges by source, a cost breakdown by trade and item, what pushes the price up, the consent and licensing rules, and how to compare quotes.

Bathroom renovation cost in NZ: budget, mid-range and high-end

No single official price list exists, so the sources below are shown side by side. Each is a published guide, not a quote, and each defines "budget" differently.

Source	What it says
Canstar (Dec 2024)	$15,000 to $45,000+; typical about $20,000 for a 9–12m² bathroom
Trade Me guide	DIY or quick refresh $5,000–$20,000; budget $20,000–$36,000; mid-range $39,000–$65,000; premium $65,000+
Pzazz Building report (via a Nuovo Group release, Jun 2024)	Simple $19,000–$22,000; mid-range $26,000–$30,000; larger or high-end $35,000+
Superior Renovations (Auckland, updated Oct 2026)	Budget refresh $8,000–$15,000; mid-range $20,000–$35,000; luxury $35,000–$65,000+
Refresh Renovations	Its own projects from about $20,000 to upwards of $90,000 (indicative)

Reading across them, a rough guide looks like this:

Budget refresh (about $5,000 to $15,000): new vanity, tapware, paint and minor tiling, with plumbing and layout left alone. Superior Renovations describes its refresh tier as like-for-like fixture swaps with existing plumbing kept.
Mid-range (about $20,000 to $40,000): a full strip-out, new waterproofing, plumbing, electrical, tiling and mid-priced fixtures. Superior Renovations puts a full renovation of a small 5–7m² bathroom at $20,000 to $30,000.
High-end ($45,000 and up): premium tiles, custom cabinetry, wet-room showers and layout changes. Superior Renovations quotes $35,000 to $65,000+ for custom luxury work, and Trade Me lists premium at $65,000+.

Canstar suggests budgeting 2% to 3% of your home's value for a bathroom. Auckland runs higher: Superior Renovations says its Auckland mid-range band is $20,000 to $35,000, against $18,000 to $26,000 nationally. Local bathroom renovators in Auckland can tell you what your suburb costs.

Bathroom renovation cost breakdown by trade and item

Itemised NZ figures are rare. The only published breakdown available is from Superior Renovations' 2026 Auckland guide, so treat these as one company's estimates for a mid-range job, not a market average.

Item	Mid-range estimate (Superior Renovations, Auckland)
Labour, all trades	$8,000–$12,000 (it says 40–50% of the total)
Materials (tiles, GIB, adhesive)	$4,000–$8,000
Fixtures (shower, toilet, vanity)	$3,000–$6,000
Plumbing	$2,000–$3,000
Electrical	$1,000–$2,000
Waterproofing	$500–$1,000 (shower area only $400–$600)
Painting and plastering	$1,500–$2,500

Line items do not add up neatly, because trades overlap and the source gives ranges. Use them to sense-check a quote, not to build one.

Individual items from the same source:

Demolition: removing an old shower unit $150–$250; hauling away debris $250–$500. It gives no whole-bathroom demolition figure.
Tiles (materials per m²): ceramic $30–$50, porcelain $50–$100, natural stone $80–$150. Canstar calls tiles one of the biggest expenses.
Shower: acrylic unit $900–$2,000; hinged glass door $800–$1,500; a full tiled shower $2,000–$9,500 including prep and removal.
Ventilation: an extractor fan costs about $200 for the fan alone. Installation is extra, and an electrician must do the wiring.

Cost to install a new bathroom vanity

Superior Renovations lists vanity unit prices at $200–$500 for laminate, $500–$1,500 for a mid-range floating vanity, $1,000–$3,000 for solid timber and $2,000–$3,000 for a luxury floating vanity. These are product prices. Fitting and connecting the taps and waste is plumber labour, so ask for it as a separate line.

What pushes a bathroom renovation price up

These are the cost drivers the sources agree on.

Moving plumbing. Canstar says moving plumbing points adds labour costs. Superior Renovations puts plumbing relocation at $1,000 to $5,000 extra. Trade Me's advice is to avoid moving plumbing or electrical work where you can.
A tiled wet-area shower. Auckland Council guidance says installing one needs a building consent, because it involves carpentry and waterproof membranes. Superior Renovations adds that wet rooms and layout changes bring engineering and 1 to 3 more weeks.
Older homes and hidden damage. Superior Renovations recommends a 15% to 20% contingency for older Auckland homes. Trade Me suggests holding 15%. Rotten framing or failed waterproofing only shows once the walls are open.
Asbestos in pre-2000 homes. WorkSafe says homes built before 1 January 2000 may contain asbestos, and you cannot tell by looking, only by testing a sample. Wet-area lining backing is among the places WorkSafe flags. Test before demolition, not after. You can find asbestos testing providers on GetListed. Refresh Renovations lists one 8m² bathroom with asbestos and underlying damage at $36,000 (May 2022).
Premium finishes. Canstar notes a stone bath can cost $10,000 on its own, and feature tiles add cost without adding much value.
Where you live. Superior Renovations quotes Auckland labour at $120–$150 an hour against $70–$100 nationally. Apartments can add handling costs for moving materials and waste.

Schedule 1 of the Building Act exempts some low-risk work, including repairing or replacing a building element with a comparable one in the same position. Everything must still meet the Building Code. Auckland Council guidance, republished by PlaceMakers (July 2024), gives these examples.

Usually no consent	Consent likely needed
Repairing or replacing an existing sanitary fixture such as a toilet pan	Installing a tiled wet-area shower
Repositioning or replacing fixtures within an existing bathroom	Adding a shower, basin or toilet to an ensuite where none existed
Replacing a bath with a shower over it with a proprietary shower enclosure and new bath in the same space	Plumbing work that could affect floor joists or wall framing
	Moving a vanity, bath or shower in a multi-level apartment (fire separations)

Plumbing and drainage work is only exempt if an authorised person does it. Your council makes the final call for your property, so ask before you start. Superior Renovations puts consent fees at $500 to $2,500, plus roughly 1 to 4 weeks.

Plumbers, electricians and LBPs

Plumbers: authorised persons are certifying plumbers and drainlayers, or provisional licence holders and trainees working under their supervision. Check the licence on the Plumbers, Gasfitters and Drainlayers Board register. Browse plumbers on GetListed.
Electricians: WorkSafe says homeowners may do only limited electrical work, such as replacing switches, socket outlets and light fittings in a home they own and live in. New circuits, fans and heated towel rails need a registered electrician.
Licensed Building Practitioners (LBPs): restricted building work covers a home's structure and weathertightness. Structural changes need an LBP, so look for licensed builders for layout changes. A Mitre10 trade update (23 July 2026) says the Government is progressing a new LBP waterproofing class, but timing and scope are not final. Ask any waterproofer about their training and for photos of the membrane before tiling.

How long a bathroom renovation takes and how to compare quotes

Timelines

Canstar says to allow three to four weeks for a fully renovated bathroom. Superior Renovations' Auckland estimates are 3 to 7 days for a budget refresh, 3 to 4 weeks for mid-range, and 4 to 8+ weeks for luxury or structural work. It also notes tradies may be 1 to 2 weeks from starting, and consent adds time.

Comparing quotes

Get at least three itemised quotes. Trade Me's guide advises taking fixed-price quotes over estimates and removing PC sums (provisional allowances), which let the final price float. Use this checklist:

Check	Why it matters
Fixed price or estimate	Fixed prices cap your risk
PC sums listed	Tiles, vanity and tapware allowances often come in low
Waterproofing, tiling and plumbing itemised	Lets you compare like with like
Consent responsibility	Who applies, and who pays the fees
Asbestos and hidden-damage plan	Avoids surprise variations
Licences and certificates	Plumber authorisation, electrical sign-off
Contract reviewed	Trade Me advises having a lawyer check it

Compare local options on GetListed for bathroom renovators in Christchurch, Wellington or Hamilton, then ask each for a written, itemised quote.

Frequently asked questions

How much does a bathroom renovation cost in Auckland?

Superior Renovations' 2026 guide puts Auckland mid-range renovations at $20,000 to $35,000 and luxury work at $35,000 to $65,000+. Budget refreshes are $8,000 to $15,000. These are one company's figures, so get several quotes for any bathroom renovation in Auckland.

How much does it cost to install a new bathroom vanity?

Vanity units range from about $200 for laminate to $3,000 for luxury floating or solid timber, based on Superior Renovations' 2026 guide. Plumber labour for fitting is extra and varies by plumber and region. Ask for it as a separate line item.

Not always. Auckland Council guidance says repositioning or replacing fixtures within an existing bathroom usually needs no consent, but a tiled wet-area shower or adding fixtures to an ensuite does. Plumbing work must be done by an authorised person to be exempt, so confirm with your council first.

What is a realistic bathroom remodel cost for a small bathroom?

Superior Renovations puts a full renovation of a 5–7m² bathroom at $20,000 to $30,000 in Auckland. It notes small bathrooms cost nearly as much as larger ones because trade costs are mostly fixed. Canstar's typical figure is about $20,000 for a 9–12m² bathroom.

How long does a bathroom renovation take?

Allow about three to four weeks for a full renovation, according to Canstar. Simple refreshes can take under a week, while structural or luxury projects can run past eight weeks. Waiting for consent or a tradie's start date can add more.
