Bathroom Renovations Auckland
Auckland Licensed Building Practitioners for complete bathroom renovations. From demolition to final walkthrough, we deliver fixed-price quotes, a 10-year Building Works Guarantee, and free in-home design consultations.
Auckland Bathroom Renovation Specialists Since 1996
Most Auckland bathrooms are one of two things: the one room nobody has touched since the 1990s, or the one room four people queue outside every morning. Cracked grout, a fan that sounds like a small aircraft, tiles that grow mould faster than you can clean them, and a vanity quietly swelling at the corners. Plenty of Auckland homeowners live with this for years because the alternative feels worse: months of disruption, hidden costs surfacing mid-build, and a different tradesperson at the door every second day.
Done well, and a bathroom renovation removes all of that.
TJ’s has been renovating bathrooms across Auckland since 1996. The TJ’s Kitchens and Bathrooms team work across villas in Mt Eden, weatherboards in Glen Eden, brick-and-tile homes in Howick, and townhouses in Auckland CBD. Each one comes with its own quirks: hidden rot behind 1970s gib, undersized waste pipes, a sloping subfloor that nobody noticed until demolition day. Three decades of Auckland work means we know what to look for before we lift the first tile.
We are Licensed Building Practitioners (LBP) and members of the National Kitchen and Bathroom Association (NKBA). Every bathroom renovation we manage is delivered under a fixed-price contract with one point of contact, one project schedule, and a 10-year building works guarantee. No juggling of subcontractors. No mystery invoices.
Why Auckland Homeowners Choose TJ's
Licensed Building Practitioners on Every Job
Bathroom renovations sit at the intersection of plumbing, electrical, gib, tiling, waterproofing, joinery, and council compliance. Auckland homeowners choose TJ’s for four specific reasons: Licensed Building Practitioner status, single-point project management, a fixed-price quote before work starts, and a 10-year guarantee.
Most bathroom renovation companies aren’t licensed builders, so structural rot uncovered behind a wall becomes a separate quote and a separate timeline. As Licensed Building Practitioners, our team handles any structural repairs in-house, keeping framing damage, wall changes, and subfloor work on the same schedule.
One Point of Contact, Full Project Management
Your project manager books the plumber, electrician, tiler, painter, and council inspector. One phone number, one written schedule, and daily progress logged through our project management software. No chasing trades and no gaps in communication.
Fixed-Price Quote Before a Single Tile Comes Out
Following your free in-home consultation, you’ll receive a detailed fixed-price quote covering every aspect of your renovation—including all trades, materials, council consents, inspections, demolition, rubbish removal, and the final clean. If you choose to make changes during the project, any variations are documented in writing and quoted separately before work proceeds.
10-Year Building Works Guarantee
Every TJ’s, a bathroom renovation is backed by a written 10-year building works guarentee in addition to the manufacturer’s warranties on tapware, vanities, tiles, and fixtures. At project completion, you’ll receive a comprehensive handover pack containing your warranty information, product documentation, and care instructions. If something we’ve built fails within 10 years due to our workmanship, we’ll come back and make it right
Our Bathroom Renovation Services
Complete Bathroom Renovations
TJ’s specialises in complete bathroom renovations across Auckland, including ensuite renovations, small bathroom renovations, family bathrooms, and custom bathroom design with 3D visualisation. Every renovation is completed under a fixed-price contract and managed by one dedicated project manager from demolition through to handover.
Complete bathroom renovations, from demolition to final walkthrough. We take care of every stage of the project, including structural repairs, framing and layout changes, Aqualine® gib installation in wet areas, E3-compliant waterproofing, tiling, custom vanities and cabinetry, plumbing, electrical, lighting, ventilation, painting, and fixture installation. Where required, we also manage the council consent process.
Ensuite Renovations
Ensuites are often the most compact spaces in an Auckland home, where clever design makes all the difference. TJ’s has renovated ensuites in Newmarket apartments, Ponsonby villas, and master suite additions across the Auckland CBD. A thoughtfully designed ensuite improves everyday living, eases demand on the family bathroom, and can increase your property’s value.
Small Bathroom Renovations
Small bathroom renovations require the same professional trades, waterproofing, and quality workmanship as larger bathrooms. The difference lies in the design. Smart layout choices, wall-hung vanities, frameless shower screens, and large-format tiles maximise space, improve functionality, and create the feeling of a larger bathroom.
Main and Family Bathrooms
Family bathrooms need to stand up to busy mornings, active households, and everyday wear and tear. Our designs focus on practicality and durability, featuring porcelain tiles, easy-to-clean wall-hung toilets, double vanities where space allows, and effective ventilation to help manage moisture year-round. Thoughtfully integrated storage is built into the design, creating a bathroom that’s both functional and easy to live with
Bathroom Design and 3D Visualisation
Before work begins, you’ll receive a detailed 3D visualisation of your new bathroom, allowing you to view the design from every angle. Tile layouts, vanity placement, mirror sizing, lighting, and shower screen positioning are finalised before construction starts. Making changes during the design stage is simple – making them once installation begins is far more costly.
Explore your new bathroom in 3D and receive a detailed fixed-price proposal within 14 days. No obligation, no surprises.
How a Bathroom Renovation Works at TJ's
Every TJ’s bathroom renovation in Auckland follows the same five-step process: design consultation, fixed-price proposal, pre-construction, construction, and final walkthrough with aftercare. The structure is what keeps the job on budget and the timeline tight.
Design Consultation and Preliminary Planning
Your renovation starts with a free in-home consultation, where we assess your bathroom, take measurements, review plumbing and electrical, and discuss your vision, priorities, and budget. We’ll provide an initial cost estimate, and if you decide to proceed, a Preliminary Agreement enables us to coordinate trades, source accurate supplier pricing, and create detailed floor plans.
Fixed-Price Proposal and Contract
You’ll receive a fully itemised fixed-price proposal, detailed floor plans, and a comprehensive building contract outlining supplier selections, trade allowances, and our variation process. Once approved, we schedule your renovation, order materials, coordinate all trades, and provide a live project timeline so you can track progress every step of the way.
Pre-Construction and Site Preparation
Before work begins, we protect surrounding areas, install dust and debris barriers, isolate utilities where required, and carry out all necessary health and safety checks. At the end of every day, we clean and tidy the site to minimise disruption and help keep the rest of your home clean and liveable.
Construction and Interior Fit-Out
From demolition to final fit-off, every stage of your bathroom renovation is professionally managed. This includes structural work, plumbing and electrical rough-ins, Aqualine® gib, waterproofing, council inspections where required, tiling, painting, cabinetry, lighting, and fixture installation. Your dedicated project manager coordinates every trade, while daily updates on our project management software keep you informed throughout the build.
Final Walkthrough and Aftercare
At handover, we’ll guide you through your completed bathroom to ensure you’re completely satisfied with the finished result. You’ll receive a comprehensive handover pack with all consents, warranties, product manuals, and trade information for future reference. Three months later, we’ll follow up to ensure everything is performing as it should. Your 10-year building works guarantee begins from the day your project is handed over.
Bathroom Renovation Cost in Auckland
Bathroom renovations in Auckland cost between $10,000 and $100,000+, depending on scope. A budget refresh runs $7,000 to $20,000. A mid-range renovation, the most common tier, runs $25,000 to $55,000. A premium or luxury renovation runs $55,000 to $100,000 or more. Auckland prices sit 10 to 20 percent above the national average because labour rates run higher, council inspection requirements are stricter, and material logistics add freight. Most TJ’s clients land in the mid-range tier.
Budget Refresh: $7,000 to $20,000
Perfect for cosmetic bathroom renovations, this option keeps your existing layout and plumbing while updating the features that make the biggest impact. New tapware, a replacement shower and vanity, fresh paint, updated mirrors, tile repairs or replacement, and an upgraded exhaust fan can transform the space. Retaining the existing plumbing layout is one of the most effective ways to keep renovation costs down, as relocating services can add significant expense and may require council consent.
Mid-Range Renovation: $25,000 to $55,000
The most common choice for Auckland homeowners, this renovation tier delivers a complete bathroom transformation while keeping plumbing locations largely unchanged to maximise value. It includes full demolition, re-gib, retiling, a new vanity and basin, modern toilet, frameless glass shower, waterproofing, updated lighting, and heated towel rail. Finished with quality porcelain tiles, New Zealand-brand tapware, and stylish cabinetry, it balances design, durability, and budget.
Premium and Luxury: $55,000 to $100,000+
Premium bathroom renovations are designed around custom layouts, high-end finishes, and luxury features. This may include freestanding baths, custom cabinetry, underfloor heating, large-format porcelain or natural stone tiles, double vanities, wet-room designs, and premium imported tapware. Where structural changes, plumbing relocations, or fully tiled wet areas are involved, Auckland Council consent may be required. Most high-end bathroom projects are completed within 6 to 8 weeks, depending on the design and scope.
Tell us about your space, and we’ll give you a realistic price range plus a free in-home consultation. No commitment, no estimate, just an exciting look at how your bathroom will be.
Factors That Influence Bathroom Renovation Costs
Six key factors influence the final cost of a bathroom renovation in Auckland: plumbing changes, tile selection and coverage, the quality of fixtures and fittings, the condition of the existing structure, council consent and waterproofing requirements, and any additional features such as underfloor heating or smart technology. One of the biggest ways to control costs is keeping the existing layout, as relocating plumbing can add anywhere from $1,500 to $5,000 to the project.
1. Plumbing Relocation
Moving a toilet, vanity, or shower to a new position can add approximately $2,000 to $6,000+, depending on access, floor structure, drainage requirements, and the complexity of the pipework changes. Keeping the existing layout is often the biggest way to control your renovation budget.
2. Tile Choice and Area
Tile selection can have a significant impact on your overall renovation cost. Standard ceramic tiles typically range from around $35 to $70 per square metre, quality porcelain tiles from $60 to $150 per square metre, while natural stone and premium imported tiles can exceed $200 per square metre. Most bathrooms require approximately 20 to 40 square metres of tiles across floors and walls, meaning the choice of tile can quickly influence the overall project cost.
3. Fixture and Fitting Quality
The quality of your fixtures and fittings can vary widely depending on the products selected. A basic toilet and vanity package may start from around $1,000 to $2,500, while premium selections such as wall-hung toilets, custom cabinetry, designer tapware, and feature fittings can exceed $5,000 to $10,000+. These are highly visible elements of your bathroom, so investing in quality products often delivers long-term value.
4. Structural Condition
Older Auckland homes, particularly those built before the 1980s, can sometimes uncover hidden issues such as water damage, deteriorated framing, outdated pipework, or subfloor problems during demolition. Unexpected repairs can add approximately 5% to 15% to the renovation budget depending on the extent of the work required. Having an experienced Licensed Building Practitioner manage these issues ensures repairs are completed correctly and efficiently.
5. Council Consent and Waterproofing
Where building consent is required, costs can vary depending on the scope of work. Allow approximately $1,500 to $8,000+ for consent-related costs, inspections, and administration, with additional fees possible for specialist drawings or engineering requirements. Waterproofing is a critical part of any bathroom renovation, particularly in fully tiled wet areas, and must be completed to meet current standards.
6. Heated and Smart Features
Additional comfort features can enhance the everyday experience of your bathroom. Underfloor heating typically costs around $1,500 to $4,000+ depending on the area covered, heated towel rails range from approximately $400 to $1,500, and illuminated smart mirrors with demisters generally start from around $600 to $1,500. While not essential, these features are popular upgrades that add comfort and functionality, especially during Auckland’s cooler months.

Building Consent and Waterproofing in Auckland
Building consent is required for any bathroom renovation in Auckland that relocates plumbing, adds a sanitary fixture, alters load-bearing walls, or creates a fully tiled wet area. Like-for-like fixture replacements (a new vanity in the same spot, retiling, replacing taps) are exempt under Schedule 1 of the Building Act 2004. Auckland Council fees run $1,500 to $6,000+ with processing in 10 to 20 working days. Waterproofing must comply with Clause E3 of the New Zealand Building Code and is inspected before tiles go down.
When Bathroom Renovations Need Consent
Schedule 1 of the Building Act 2004 allows many bathroom renovations to be done without a building consent, including like-for-like replacements such as a new vanity in the same location, replacing fixtures or fittings, retiling without changing the layout or adding a mirror.
A building consent is generally required if you relocate plumbing or drainage, alter load-bearing walls, add new sanitary fixtures where required, or make changes to the building envelope.
As Licensed Building Practitioners, we can manage the entire consent process for you, from preparing and lodging the application through to securing your Code Compliance Certificate.
Waterproofing and the E3 Building Code
Clause E3 of the New Zealand Building Code sets the standards for managing internal moisture, making waterproofing a critical part of any bathroom renovation. Tiles are not waterproof—the membrane beneath them protects your home from leaks and moisture damage.
Every tiled wet area should be waterproofed using a compliant membrane system installed to the manufacturer’s specifications. Where a building consent is required, the membrane is inspected before tiling.
At TJ’s Kitchens & Bathrooms, we use trusted waterproofing systems to ensure every bathroom is built to New Zealand Building Code requirements for lasting performance.
Bathroom Styles and Design Options
TJ’s renovates bathrooms in a wide range of styles to suit every home and lifestyle. Some of our most popular designs include modern minimalist, spa-inspired retreats, classic and timeless bathrooms, and practical family-friendly spaces. Our designers work with you to create a bathroom that complements your home, suits your family’s needs, and reflects your personal style.
Modern Minimalist
Defined by clean lines, large-format porcelain tiles, frameless glass showers, wall-hung vanities, and matte black or brushed nickel tapware, this contemporary style suits everything from modern homes and apartments to newly renovated properties across Central, South, East and West Auckland.
Spa-Like Retreat
Natural stone or timber-look tiles, a freestanding bath, walk-in shower with a rainfall shower head, warm ambient lighting, and heated towel rails create a relaxing, spa-inspired retreat. This style is ideal for larger bathrooms with space for separate bathing and showering zones, bringing a touch of luxury to everyday living.
Classic and Timeless
White subway tiles, chrome or brushed nickel tapware, pedestal or traditional-style vanities, and timeless detailing create a classic bathroom that never goes out of style. Perfect for character homes or anyone wanting a design that blends traditional charm with modern functionality.
Family-Friendly and Practical
Designed for busy households, family bathrooms prioritise practicality, durability, and easy maintenance. Features often include non-slip floor tiles, double vanities where space allows, shower-over-bath layouts, wall-hung toilets for easier cleaning, and smart storage solutions to keep everyday essentials organised.

FAQs
How much does a bathroom renovation cost in Auckland?
Most bathroom renovations in Auckland cost between $25,000 and $55,000 for a mid-range finish. A budget refresh starts at $7,000 to $25,000, and a full luxury renovation can run from $65,000 or more. Prices in Auckland sit 10 to 20 percent above the national average because labour rates and material logistics are higher. Biggest cost drivers are labour (around 40 to 50 percent of the total), tiling and waterproofing, and any plumbing relocation. Every TJ’s quote is fixed-price and fully itemised, so you know your total cost before any work starts.
Do I need building consent to renovate my bathroom in Auckland?
It depends on the scope. Like-for-like fixture replacement, retiling without changing the wet-area footprint, painting, and installing new cabinetry without altering plumbing are all exempt under Schedule 1 of the Building Act 2004. Consent is required if you relocate plumbing, add a new sanitary fixture, alter load-bearing walls, or create a fully tiled wet area. Council fees through Auckland typically run $1,500 to $6,000+ with inspections, and processing takes 10 to 20 working days. As Licensed Building Practitioners, TJ’s manages the entire consent process on your behalf, from drawings through to the final Code Compliance Certificate.
How long does a bathroom renovation take?
Auckland bathroom renovations typically take around 6 weeks from demolition to final walkthrough, assuming no major structural changes or consent delays. Simple cosmetic refreshes can be done in 1 to 2 weeks. Premium renovations involving wall changes, layout reconfiguration, or full council consent typically run 6 to 8 weeks. Common causes of delay are materials on backorder, hidden rot uncovered during demolition, and consent processing through Auckland Council. Selecting all fixtures and tiles before the start date is the single most effective way to keep the project on schedule.
Does a bathroom renovation add value to my home?
Yes. Modern, well-finished bathrooms are one of the first rooms buyers inspect when evaluating an Auckland home. Updated bathrooms signal that the rest of the property has been cared for, which lifts both perceived and actual sale value. Beyond resale, a bathroom renovation also improves daily comfort, fixes lurking issues like outdated wiring or hidden moisture damage, and reduces ongoing maintenance. Energy-efficient features such as low-flow toilets, LED lighting, and water-saving tapware also appeal to environmentally conscious buyers. TJ’s has helped Auckland homeowners and property investors increase home value through bathroom renovations since 1996.
How much does an ensuite renovation cost in Auckland?
Ensuites typically cost slightly less than a main bathroom because the floor area is smaller, but the per-square-metre cost is often higher. Fixed trade costs (plumbing, electrical, waterproofing, consent) do not shrink with the room size. Auckland ensuite renovations usually sit between $30,000 and $50,000 for a mid-range finish covering retiling, a new vanity and basin, a frameless shower, a wall-hung toilet, lighting, and ventilation. Ensuites in apartments or upper-floor master suites can run higher because access for trades and material handling is harder.
Can I live in my home during a bathroom renovation?
Yes, in most cases. When you have a second bathroom in the house, the renovated bathroom can be fully offline for the duration. With only one bathroom, we phase the work so a working toilet and basic washing facilities stay available for as much of the project as possible, although there will usually be a few days with no shower. Your project manager talks through the live-in plan during the consultation and builds it into the schedule. Almost every client stays in their home for the entire renovation.
How do I choose the right bathroom renovation company?
Consider three important questions. First, are they Licensed Building Practitioners? Many bathroom renovation companies are not, which means they cannot legally handle structural work uncovered during demolition. Second, do they provide a fully itemised fixed-price quote, or just an estimate? Estimates often grow. Third, do they offer a written building works guarantee, and for how long? A 10-year written guarantee is the industry standard for serious renovators. Ask each company you interview these three questions and compare the answers directly. Cheapest quotes are rarely the cheapest job at the end.
What is the difference between a bathroom remodel and a bathroom renovation?
In New Zealand, the terms bathroom renovation and bathroom remodel are often used interchangeably. “Remodel” is more common in the United States and typically refers to changing the layout, while “renovation” is the preferred Kiwi term and covers everything from cosmetic upgrades to complete bathroom transformations.
At TJ’s Kitchens & Bathrooms, we use the term bathroom renovation because it reflects the complete service we provide—managing every stage of the project, from design and planning through to trades, suppliers, and the final handover.
Do you renovate bathrooms outside the central city, like West Auckland or East Auckland?
Yes. TJ’s Kitchens & Bathrooms services Central, East, South and parts of West Auckland, from New Lynn across to East Auckland and south to Bombay. We regularly complete renovations in suburbs including Point Chevalier, Grey Lynn, Avondale, Onehunga, Ellerslie, Remuera, New Market, Pakuranga, Howick, Botany, Manukau, Papakura, Takanini, Pukekohe and the surrounding areas.
