What’s The Average Bathroom Renovation Cost In NZ?
If you’re planning a bathroom renovation in New Zealand, one of the first questions you’ll probably ask is: how much will it cost? In 2025, the average bathroom renovation cost in NZ typically falls between $15,000 and $30,000. This range covers everything from basic improvements to more complete redesigns.
For a budget-friendly renovation, where the layout stays the same and materials are cost-effective, you might spend around $12,000 to $18,000. This often includes replacing old fixtures, repainting, new flooring, and minor updates to tiles or vanities.
If you’re aiming for a mid-range renovation, expect to pay about $20,000 to $28,000. This price range allows for more flexibility with materials and finishes. It usually includes new plumbing fixtures, moderate layout changes, updated lighting, and better-quality tiles or cabinetry.
For those considering a luxury bathroom makeover, the cost can go up to $35,000 or more. High-end renovations often feature custom fittings, designer vanities, underfloor heating, walk-in showers, frameless glass, and premium tiles. These projects may also involve significant plumbing or electrical work and structural changes, which add to the final price.
Knowing where your project sits on this scale can help you budget realistically and plan with confidence. Always factor in a 10–15% buffer for unexpected expenses.
Key Cost Factors To Consider
Bathroom renovation costs in New Zealand can vary widely. Before jumping into a project, it’s important to understand what actually drives the final price. Whether you’re working with a tight budget or planning a full luxury fit-out, knowing these key factors will help you make smarter decisions.
Size Of The Bathroom
The size of your bathroom directly affects your renovation cost. Larger spaces need more materials, more time, and more labour.
- Small bathrooms (under 5m²) are generally cheaper to renovate but still require essentials like plumbing and tiling.
- Medium to large bathrooms (6–10m² or more) mean more surface area for tiles, more fittings, and often higher labour costs.
Quick Tip: Don’t assume a small bathroom equals a cheap reno, tight spaces can require more custom work and precision.
Quality Of Materials
Material choices can make or break your budget. Tiles, flooring, paint, and waterproofing products all come in a wide range of prices.
- Vinyl or laminate flooring is budget-friendly.
- Porcelain or natural stone tiles cost more but look and last better.
- Waterproofing membranes, while invisible, are non-negotiable for compliance and long-term durability.
Spend where it counts, you can save on accessories, but don’t skimp on waterproofing or surfaces that see daily wear.
Fixtures & Fittings
The price of your taps, showerheads, vanities, toilets, and mirrors can vary hugely based on style and brand.
Here’s a cost comparison to help:
- Budget tapware: $150
- Mid-range tapware: $300
- Designer tapware: $600+
A simple shower unit might cost $500, while a walk-in tiled shower can be $3,000 or more. Toilets range from $200 to over $1,000 depending on brand and design.
Tip: Avoid trendy fittings unless you’re willing to replace them down the track. Choose timeless styles that hold resale value.
Plumbing & Electrical Work
This is where many hidden costs appear. Shifting plumbing or rewiring lighting adds complexity and time.
- Moving a toilet or shower? That’s extra pipework and labour.
- Adding underfloor heating or LED mirrors? That adds electrician hours and compliance costs.
If your home is older, you might need upgrades to meet modern plumbing or wiring codes. Always factor this into your budget, even if you can’t see it.
Labour Costs (Region Matters!)
Labour is often the biggest single expense in a bathroom renovation. Rates vary based on where you live in New Zealand.
- Auckland and Wellington have higher hourly rates due to demand and cost of living.
- Smaller towns may offer lower rates, but availability can be an issue.
Expect to pay:
- Builders: $50–$120/hour
- Plumbers: $90–$150/hour
- Electricians: $80–$130/hour
- Tilers: $60–$100/hour
Tip: Always get itemised quotes and ask if the price includes GST, materials, and waste disposal.
Council Consents Or Permits
Not all bathroom projects need council approval, but some do. If you’re changing the layout, structure, or drainage system, consent may be required.
- Consent application fees range from $500 to $1,000+ depending on your region.
- You may also need a certified plumber or electrician to sign off the work for compliance.
Skipping this step could cause issues when selling your property or claiming insurance.
If you’re altering what’s behind the walls or floor, talk to your local council first.
Understanding these key cost factors will help you budget with clarity. Each decision, big or small, affects the final price. So weigh your priorities, compare options, and focus on where you’ll get the best value for your money.
Real Examples: Budget Vs. Premium Bathrooms
Understanding the real cost of bathroom renovations in New Zealand becomes much easier when you look at actual examples. Let’s explore two real-world case studies, one focused on a basic, budget-friendly makeover, and the other on a high-end transformation. These examples will give you a clearer picture of where the money goes, what can be skipped, and what upgrades make a big difference.
Case Study 1: Budget Reno In Christchurch – $13,000
This homeowner in Christchurch wanted to update a tired 1990s bathroom without overspending. The goal was to keep the layout, modernize the look, and stay under $15,000.
What Was Included:
- Kept the existing plumbing layout to save on labour
- Replaced old vinyl with mid-range porcelain floor tiles
- Installed a new prefabricated vanity and standard acrylic shower
- Added a new toilet and mixer taps
- Painted walls with moisture-resistant paint
- Upgraded basic lighting to LED
What Was Skipped:
- No underfloor heating
- No changes to pipework or layout
- Used standard hardware, not designer brands
- No tiled shower walls, acrylic shower box used instead
The result was a clean, fresh, and functional space that looked new without blowing the budget. Most of the cost went into tradie labour, basic fixtures, and floor tiling. It was a smart, cost-effective solution for a family that needed a practical upgrade.
Case Study 2: High-End Reno In Auckland – $38,000
This renovation took place in a character home in Auckland’s North Shore. The owners wanted a luxurious, modern bathroom that could match the rest of their upgraded home.
What Was Included:
- Full layout redesign with wall removal
- Custom-built double vanity with engineered stone benchtop
- Frameless glass walk-in shower with tiled walls and niche shelving
- Free-standing stone bathtub
- High-end brass tapware and rain-style showerhead
- Underfloor heating and wall-hung towel warmer
- Floor-to-ceiling designer tiles
- Recessed LED lighting and mirror with backlight
- Painting and finishing by a professional decorator
What Was Skipped:
- Nothing, the clients went for a complete renovation experience
This project involved multiple tradies and required council consent due to structural changes. The overall aesthetic was sleek and luxurious. It added serious value to the home, both functionally and visually.
What These Examples Show
Both renovations served the homeowner’s needs, but the price difference came down to scale, finishes, and scope. If you’re looking to renovate your bathroom in New Zealand, these examples show that you can get solid results on a budget, or go all-in for a premium feel. Your priorities, goals, and budget will ultimately shape the best path forward.
Hidden Costs You Might Miss During A Bathroom Renovation
Renovating a bathroom in New Zealand can be exciting, but it’s rarely as straightforward as you expect. While your quote may cover the main work, there are hidden costs that can easily catch you off guard. If you don’t plan for them, your budget could blow out before the tiling even begins.
Removing Old Materials
Demolition isn’t always included in your renovation quote. Tearing out old tiles, cabinetry, or flooring can add anywhere from a few hundred to a few thousand dollars to your total. If you discover asbestos in the walls or flooring, safe removal by certified professionals is mandatory, and costly.
Tip: Ask your contractor whether demolition and disposal fees are included upfront. It’s better to be clear than surprised later.
Unexpected Water Damage
This is one of the most common and expensive hidden costs. Water leaks behind tiles or under flooring often go unnoticed until renovation work begins. By then, you might be dealing with swollen floorboards, mould, or even structural issues.
Fixing water damage could mean extra labour, materials, and time. In some cases, you may even need to replace framing or subflooring to meet safety standards.
Extra Tiling Or Waterproofing
Your original plan may not include full tiling or full waterproofing. But once work begins, you might find it’s necessary, especially if you’re changing the layout or removing a bathtub. That’s when extra tiling and waterproofing costs creep in.
Tiling a full wall instead of half can double your material and labour costs. And if your waterproofing doesn’t meet New Zealand building standards, it can lead to expensive repairs down the track.
Tip: Get clarity on the scope of waterproofing in your quote. A small increase upfront is better than major water damage later.
Upgrade To Meet Building Code
Bathroom renovations must comply with the latest New Zealand Building Code. If your current plumbing or electrical systems are outdated, your tradies may need to bring them up to code before completing the work.
This might involve:
- Replacing old pipes
- Updating fuse boxes
- Installing proper ventilation
These upgrades aren’t optional, they’re required for compliance and resale value. Unfortunately, they’re not always factored into initial cost estimates.
Hidden costs are part of nearly every bathroom renovation, especially in older homes. Always build in a 10–15% buffer to your budget so you’re not scrambling when the unexpected happens. When you’re informed and prepared, the process becomes far less stressful, and your results are far more satisfying.
How To Reduce Your Bathroom Renovation Costs
Renovating a bathroom doesn’t always mean spending big. With smart planning and a few cost-saving choices, you can create a stylish, functional space without overspending. This section covers practical ways to keep your budget in check while still getting a result you’ll love.
Keep The Layout The Same
One of the most effective ways to save money is by keeping the existing layout. Moving plumbing or electrical points can quickly add thousands to your budget.
By leaving the shower, toilet, and vanity where they are, you avoid extra labour costs, council approvals, and potential hidden issues behind walls or under floors.
Example: Keeping your shower in the same spot might save you $2,000–$5,000 in plumbing work alone.
Go For Mid-Range Fittings
High-end fittings can look amazing, but they often come with a premium price tag. Mid-range options from reputable brands offer solid quality and style, without the luxury markup.
What to look for:
- Water-efficient taps and showerheads
- Durable materials like ceramic and stainless steel
- Warranties of 5 years or more
You don’t have to choose the cheapest, but avoid overspending on features you won’t use.
Source Tiles Or Vanities Yourself
Builders and suppliers often add margins to products they source for you. If you’re comfortable doing a bit of research, you can find tiles, vanities, or tapware at better prices from trusted retail stores or online.
Tip: Buy during seasonal sales or end-of-line clearances to save even more. Just check with your contractor to ensure what you buy fits the design and meets building standards.
Get Multiple Quotes
Don’t settle for the first price you receive. Always compare at least three quotes from different builders or renovation companies.
Ask for a detailed breakdown so you can see what’s included, and what’s not.
Why it matters:
- Some quotes may exclude demolition, rubbish removal, or waterproofing
- Labour rates vary by region and experience
- You may find one tradie offers better advice or clearer timelines
DIY Painting Or Demolition (If Safe)
Labour is one of the biggest renovation expenses. If you have the time and tools, doing minor tasks like demolition or painting can reduce your total bill.
Safe DIY jobs might include:
- Removing old tiles or fittings
- Prepping and painting walls
- Cleaning up between trades
Avoid DIY if:
- You’re unsure about plumbing or electrical work
- You don’t have the right gear
- There’s risk of damaging structural parts or waterproofing
Do Vs. Don’t Table
Here’s a quick table to help guide your renovation decisions:
| Do | Don’t |
| Stick to the current layout | Move plumbing unless absolutely necessary |
| Choose durable mid-range fixtures | Pay extra for brand names without research |
| Shop around for tiles and vanities | Let your builder pick everything unchecked |
| Compare multiple quotes | Accept vague or verbal pricing |
| DIY painting and basic prep work | Tackle electrical or plumbing without training |
Every dollar you save on one part of your bathroom can go into upgrading another. By focusing on smart, informed decisions, you can create a result that looks high-end, without the high-end price. Want a tailored renovation checklist? Just ask.
Cost Breakdown Table: What You’re Really Paying For
Before you dive into your bathroom renovation, it helps to understand where your money is going. Knowing the average cost ranges for each part of the project can help you plan a realistic budget, avoid overspending, and make smarter decisions.
Here’s a detailed look at the typical costs involved in a bathroom renovation in New Zealand:
| Item | Estimated Cost Range (NZD) |
| Demolition | $500 – $2,000 |
| Plumbing & Electrical | $2,000 – $6,000 |
| Fixtures & Fittings | $2,500 – $10,000 |
| Tiling | $1,500 – $5,000 |
| Labour | $4,000 – $12,000 |
Demolition ($500 – $2,000)
This covers the removal of old tiles, vanities, fittings, and walls if needed. It may seem minor, but it’s labour-intensive and needs to be done carefully to avoid damaging pipes or wiring. DIY demolition can save money, but it carries risks if you’re not experienced.
Plumbing & Electrical ($2,000 – $6,000)
Any change to the layout, like moving your toilet or vanity, will increase these costs. Certified tradies are required for safety and compliance. Even if you’re just updating taps or lighting, expect this category to be a major chunk of your budget.
Fixtures & Fittings ($2,500 – $10,000)
This includes your toilet, vanity, basin, shower, tapware, and any extra features like heated towel rails. Prices vary widely depending on design and brand. A simple suite might cost $2,500, while premium or custom fittings can push you closer to the $10,000 mark.
Tiling ($1,500 – $5,000)
Tiling costs depend on the size of the space, the type of tile, and how much wall tiling you want. Full wall and floor tiling costs more, especially with intricate designs or high-end tiles. Labour adds a large portion of the total in this category.
Labour ($4,000 – $12,000)
Labour includes project management, builders, waterproofers, and painters. This is often the single biggest expense. The more complex the job, the more time it takes, especially when coordinating multiple trades.
Quick Tip: Always keep 10–15% of your total budget aside for surprise costs. Hidden water damage, outdated wiring, or supply delays can quickly add up.
DIY Vs. Hiring Professionals: What You Need To Know In NZ
Renovating your bathroom can be an exciting project, especially if you’re thinking about doing some of the work yourself. But before picking up the tools, it’s important to understand what you can legally DIY in New Zealand, and when you must call in the experts. This section will help you decide what’s right for your skills, your schedule, and your budget.
What’s Legal To DIY In NZ
In New Zealand, you’re allowed to do certain types of bathroom renovation work on your own. This includes:
- Painting walls and ceilings
- Installing towel rails, shelves, and mirrors
- Removing old fittings and tiles (as long as they’re not asbestos)
- Installing flat-pack vanities or storage units
- Minor non-structural demolition (with care)
But there are strict legal limits on what you can do with plumbing and electrical systems. According to NZ law, you cannot install or alter plumbing or wiring unless you’re a licensed professional. Doing so not only risks serious safety issues, it can also void your insurance or delay any future property sale.
When You Need Certified Tradies
You’ll need to hire a licensed professional for:
- All electrical work, including lighting, power points, or underfloor heating
- Plumbing work such as installing taps, toilets, and drainage
- Waterproofing and tanking (this often needs certification for compliance)
- Structural changes, like moving walls or doorways
- Anything requiring council consent
Always check if the work requires a Building Consent. Your local council website can help confirm this, or you can talk to a renovation company to walk you through the process.
Pros And Cons Of Each Approach
DIY Pros:
- Can save money on labour
- Gives you full control over the pace and style
- Can be satisfying if you enjoy hands-on projects
DIY Cons:
- Can be time-consuming and physically demanding
- Risk of costly mistakes or injuries
- Some tasks may not meet building code standards
- Limited to non-regulated work
Hiring Pros:
- Professional-quality finish
- Work completed faster and more efficiently
- Tradies know code requirements and can handle consents
- Peace of mind with warranties and insurance
Hiring Cons:
- Higher cost due to labour charges
- Less control over timelines (depends on tradie availability)
- You may need to manage different contractors if not using a renovation company
Time Vs. Money Trade-Off
If you’re short on time or need the job done right the first time, hiring professionals is often the better choice. While you’ll pay more upfront, you’ll likely save on stress, delays, and future repairs.
If you’re comfortable with tools, have some free weekends, and want to reduce the cost, then DIY could be worth it, for tasks like painting or demolition. Just know your limits, and don’t try to cut corners on plumbing or electrical work.
The best approach is often a mix. Handle the parts you’re confident in and leave the rest to licensed professionals. This lets you stay involved without risking legal or safety issues. Always weigh the cost of your time, skills, and the potential impact on your renovation’s quality.
How To Choose The Right Renovation Partner
Hiring the right renovation partner can make or break your bathroom project. You’re not just paying for materials and labour, you’re trusting someone with access to your home, budget, and expectations. Here’s how to choose a bathroom renovation professional in New Zealand who delivers quality work and peace of mind.
Check Reviews And Past Work
Start by looking for online reviews on Google, Facebook, or local directories. Look beyond star ratings, read the comments. Do clients mention punctuality, cleanliness, or quality? Are there repeat customers or referrals? These details give real insight into how the team works.
Don’t stop at reviews. Ask to see photos of completed bathrooms. A trustworthy contractor will have a portfolio or website with examples. Look for variety, attention to detail, and similar projects to yours. If they’ve done bathrooms in homes like yours, it’s a good sign they understand what you need.
Ask About Licensing And Insurance
Always confirm if the renovation company or contractor is licensed under NZ building codes. They should also be members of trade bodies like New Zealand Certified Builders or the Master Plumbers Association. Licensing ensures they meet legal and safety standards.
Insurance is just as critical. Ask for proof of public liability insurance and, if needed, builder’s warranty insurance. This protects you in case of accidents or damage during the project.
Compare Itemized Quotes
Never go with the first quote you receive. Aim for at least three, and make sure each one includes an itemized list. This helps you compare apples to apples, not just total prices. Look for:
- Materials and brand names
- Labour rates
- Timeline estimates
- Payment schedules
If a quote is missing detail or looks too good to be true, that’s a red flag. Vague pricing often leads to surprise charges later.
Communication Is Key
Even the most skilled tradie won’t be a good fit if they don’t communicate well. Pay attention to how quickly they respond, how clearly they answer your questions, and how willing they are to explain their process.
You should feel comfortable asking questions and expressing concerns. A good renovation partner will keep you informed from start to finish and won’t go silent when problems arise.
Ask Yourself This One Important Question
Before signing any agreement, ask yourself: “Would I trust them with my home while I’m at work?”
If the answer isn’t a confident yes, keep looking. Trust isn’t just about qualifications, it’s about how you feel after every meeting, call, or email.
A reliable renovation partner won’t just get the job done, they’ll make the whole process smoother, faster, and less stressful. Take the time to choose someone who treats your project like it matters. Because it does.
