A bathroom renovation in Auckland costs between $15,000 and $55,000 in 2026. A cosmetic refresh (new tiles, vanity, tapware, and fixtures in existing positions) runs $15,000–$25,000. A mid-range renovation with layout changes and plumbing relocation costs $25,000–$40,000. A full gut renovation with premium finishes, custom joinery, and underfloor heating starts at $40,000 and can exceed $55,000 for large or complex bathrooms.
Those are real figures from projects we’ve completed at Intelli Design Homes across Auckland this year. Not national averages, not 2023 data, not estimates pulled from overseas markets. Auckland-specific, 2026-current pricing.
This guide breaks down exactly where your money goes, what drives costs up or down, and how to set a realistic budget before you talk to a builder.
Bathroom Renovation Cost by Scope (2026 Auckland)
The biggest factor in your bathroom renovation cost isn’t materials or fixtures. It’s scope. What are you actually doing to the room?
Cosmetic Refresh: $15,000–$25,000
What’s included:
- Strip and retile floor and walls (up to 2.1m height)
- New waterproofing membrane
- Replace vanity, basin, and mixer
- Replace toilet
- Replace shower mixer and head (existing valve position)
- New shower screen (semi-frameless)
- Lighting upgrade
- Paint ceiling and any non-tiled walls
- Accessories (towel rails, toilet roll holder, robe hooks)
What’s NOT included:
- Moving any plumbing points
- Structural changes
- Underfloor heating
- Freestanding bath
- Custom joinery
This is the most popular tier for Auckland homeowners who want a fresh, modern bathroom without relocating anything. The layout stays the same, the plumbing stays where it is, and you get a completely new look in 4–5 weeks.
Mid-Range Renovation: $25,000–$40,000
Everything in the cosmetic refresh, plus:
- Plumbing relocation (shower, vanity, or toilet moved to new positions)
- Layout reconfiguration within existing footprint
- Building consent and associated fees
- Frameless glass shower screen
- Wall-hung vanity with soft-close drawers
- Heated towel rail
- Premium tapware (Methven, Felton, or equivalent NZ brands)
- Feature tiling or accent niche
- Possible underfloor heating
This tier is for homeowners who want a better-functioning layout, not just a cosmetic upgrade.
Full Gut Renovation: $40,000–$55,000+
Everything above, plus:
- Complete demolition to framing
- Possible wall removal or space expansion
- Floor levelling or structural reinforcement
- Underfloor heating (standard)
- Custom joinery vanity with stone benchtop
- Premium fixtures throughout (freestanding bath, rain shower, wall-mounted tapware)
- Floor-to-ceiling tiling on all walls
- Frameless hinged shower enclosure
- LED lighting design (recessed, mirror, and accent)
- Smart controls (digital shower mixer, underfloor heating thermostat)
The full gut is a ground-up rebuild of the bathroom.

What Drives Bathroom Renovation Costs Up
Plumbing relocation on concrete slabs. Moving a shower drain or toilet on a concrete slab requires cutting into the slab, relocating the drain, and patching. This alone adds $3,000–$5,000 compared to a timber-framed floor.
Tile selection. The difference between a $45/m² ceramic tile and a $180/m² porcelain or natural stone tile, over 30m² of wall and floor, is $4,000+ in supply alone.
Custom joinery. A standard wall-hung vanity costs $800–1,500. A custom-built solid timber vanity with stone benchtop runs $3,500–$8,000.
Hidden damage. Rotten framing behind tiles, failed waterproofing, or asbestos-containing materials all add unplanned cost. Budget a 10–15% contingency buffer.
Accessibility requirements. Walk-in showers, grab rails, wider doorways, and compliant toilet heights add cost but are increasingly common in Auckland renovations.
Where to Save Without Sacrificing Quality
Keep plumbing in existing positions. Saves $3,000–$8,000 and eliminates the need for building consent.
Choose local-stock tiles. Tiles from Auckland suppliers (Tile Warehouse, Tile Space, Vida) cost 30–50% less than imports.
Standard vanity sizes. Off-the-shelf vanities (750mm, 900mm, 1200mm) cost 40–60% less than custom builds.
Combine rooms. Doing an ensuite and family bathroom together saves 10–15% on the second bathroom.
How Auckland Costs Compare to Other NZ Cities
Auckland is the most expensive city in NZ for bathroom renovations. Labour rates are 15–25% higher than Christchurch, Wellington, or Hamilton. The same mid-range renovation that costs $30,000–$35,000 in Auckland might run $25,000–$30,000 in Christchurch.

Fixed-Price vs Cost-Plus Contracts
Fixed-price: You agree on the total price upfront after design. The builder carries the risk of cost overruns. You know exactly what you’re paying.
Cost-plus: You pay actual cost of labour and materials plus a margin (15–25%). Your final price is uncertain until handover.
We use fixed-price contracts exclusively at Intelli. No “allowances” that blow out. No “variations” for things that were obvious at quoting stage.
Red Flags in Bathroom Renovation Quotes
Vague allowances. “Tiles: $2,000 allowance” means nothing if you haven’t selected tiles.
Missing items. Check every quote includes: demolition, disposal, waterproofing, consent fees, all trades, materials, and GST.
No mention of waterproofing inspection. Any consented bathroom renovation requires council inspection before tiling.
Price significantly below market. If three quotes come in at $30,000–$35,000 and one comes in at $18,000, the cheap one is either missing scope or planning to hit you with variations.
