What Can You Actually Get for $15,000, $25,000, and $45,000+?
The average cost of a bathroom renovation in Sydney ranges from $25,000 to $45,000 for a standard renovation. A cosmetic refresh starts from around $15,000, while premium renovations involving layout changes, custom joinery, and high-end fixtures can exceed $70,000. Your final cost depends on the scope of work, material selections, whether plumbing needs to be relocated, and the size and condition of your existing bathroom.
Below, you’ll find detailed pricing tables, a full cost breakdown by trade category, and a clear comparison of budget, standard, and premium renovation tiers so you can see exactly what your money buys at each price point.
At Jonathan Homes, we handle bathroom renovations across Sydney’s Inner West and beyond, from quick cosmetic refreshes to full structural rebuilds. Every project is managed personally by licensed builder Jonathan Jamu, with fixed-price contracts so there are no surprises.
A cosmetic bathroom refresh in Sydney starts from around $15,000 if you keep the existing layout, retain functional plumbing, and focus on surface-level upgrades with professional trades. If your plans involve a full strip-out with new waterproofing and tiling, you’re looking at $25,000 as a realistic starting point, and $45,000 or more for a fully custom result with layout changes.
The table below shows what each budget tier includes for a standard Sydney bathroom (approximately 4–7 square metres):
| Budget Tier | Price Range | Scope | Best For |
|---|---|---|---|
| Cosmetic Refresh | $15,000 – $25,000 | New vanity, tapware and mirror upgrade, re-tiling or tile resurfacing, fresh paint, updated lighting, no plumbing relocation | Investment properties, functional bathrooms needing a modern update |
| Standard Renovation | $25,000 – $45,000 | Full strip-out, new waterproofing, floor-to-ceiling tiling, new fixtures and fittings, same layout | Owner-occupiers wanting a complete refresh without structural changes |
| Premium / Structural | $45,000 – $70,000+ | Layout changes, plumbing relocation, wall removal, custom joinery, underfloor heating, premium fixtures | Forever homes, ensuites, heritage properties, accessibility upgrades |
$15,000 – $25,000: The Cosmetic Refresh
At this level, you’re keeping the existing layout and plumbing positions but upgrading everything visible. A typical cosmetic refresh includes a new vanity with engineered stone benchtop, quality tapware and mixer upgrades, a new mirror and lighting, re-tiling or professional tile resurfacing, fresh paint, and updated towel rails and accessories. All work is completed by licensed trades including a plumber, electrician, and tiler.
This tier works well for bathrooms where the layout is functional but the finishes are dated. It won’t address underlying structural issues or allow you to move fixtures, but it delivers a noticeably transformed space. It’s important your existing wet-area membrane is still in good condition, as full waterproofing adds cost and pushes the project into the standard tier.
$25,000 – $45,000: The Standard Renovation
This is the most common tier for Sydney homeowners. Everything comes out (tiles, fixtures, vanity, sometimes the bathtub) and new waterproofing, tiling, and fittings go in. The key distinction from the cosmetic tier is that you’re stripping back to the studs and starting fresh, which means you get new waterproofing (a legal requirement under the Building Code of Australia whenever the membrane is disturbed), professional tiling to walls and floor, quality fixtures and fittings from brands like Caroma, Phoenix, or Methven, a new vanity with stone or engineered stone benchtop, proper ventilation, and updated electrical including new lighting.
At the standard level, you’re keeping the existing layout. The moment you start moving plumbing, even shifting the toilet by half a metre, costs jump significantly because it involves modifying the drainage stack and potentially the floor slab.
$45,000 – $70,000+: The Premium or Structural Renovation
This tier is for homeowners building their forever bathroom. It covers everything in the standard scope plus layout redesign and plumbing relocation, wall removal or repositioning (structural engineer required for load-bearing walls), custom joinery and cabinetry, premium fixtures from brands like Astra Walker, Brodware, or Gessi, underfloor heating, frameless glass, floor-to-ceiling feature tiling, and niche shelving.
Heritage properties in Sydney’s Inner West often fall into this tier due to additional complexities like asbestos removal, lead paint management, and working within heritage overlay requirements. Jonathan Homes specialises in these projects. See our heritage restoration services for more detail.
Quick self-check: If your renovation plan involves moving the toilet even 10 centimetres, factor in an additional $3,000–$5,000 for plumbing relocation alone. If it involves modifying a load-bearing wall, add $5,000–$10,000 for the structural engineer’s report and associated building work.
Where Does the Money Actually Go? A Realistic Budget Breakdown
Understanding how your renovation budget is allocated helps you make informed decisions about where to spend and where to save. Here’s how a typical standard bathroom renovation ($25,000–$45,000) breaks down:
| Cost Category | % of Budget | Typical Range (Standard Reno) |
|---|---|---|
| Labour (plumber, tiler, electrician, builder) | 35–45% | $8,750 – $20,250 |
| Tiles and waterproofing | 20–25% | $5,000 – $11,250 |
| Fixtures, fittings and tapware | 15–20% | $3,750 – $9,000 |
| Vanity, cabinetry and storage | 8–12% | $2,000 – $5,400 |
| Demolition and waste removal | 5–8% | $1,250 – $3,600 |
| Contingency | 10–15% | $2,500 – $6,750 |
Why Labour Is the Biggest Cost
A standard bathroom renovation requires a minimum of four licensed trades: a plumber, an electrician, a waterproofer, and a tiler. In Sydney, licensed tradespeople charge between $70 and $120 per hour depending on the trade and experience level. A standard renovation typically requires 5–8 days of combined trade labour on site.
The most expensive single line item is almost always plumbing. Even a straightforward like-for-like replacement (keeping everything in the same position) involves disconnecting and reconnecting water supply, waste lines, and potentially gas if you have a gas hot water system feeding the bathroom. If you’re relocating any fixtures, the plumber needs to modify pipework within the floor slab or wall cavity, and that’s where costs escalate quickly.
Waterproofing: The Non-Negotiable
Under Australian Standard AS 3740 and the Building Code of Australia, all wet areas must be professionally waterproofed by a licensed waterproofer. This is not optional. If you skip it or use an unlicensed operator, your building insurance is void and you may face issues at resale. A standard waterproofing application for a bathroom costs between $1,500 and $3,000 depending on size and complexity. For more on regulatory requirements, see our guide to council approvals for home renovations.
The Contingency Is Not Optional
Every experienced builder will tell you the same thing: set aside 10–15% of your budget as a contingency. In older Sydney homes (particularly pre-1980s fibro or weatherboard properties), opening up walls and floors almost always reveals something unexpected: deteriorated framing, asbestos sheeting, failed waterproofing from a previous renovation, or non-compliant plumbing. For guidance on setting your overall renovation contingency, see our home renovation budgeting guide.
Off-the-Shelf vs Custom: Which Route Saves You More?
One of the biggest cost decisions in a bathroom renovation is whether to use off-the-shelf products (from retailers like Bunnings, Beaumont Tiles, or Reece) or go the custom route with trade-supply fixtures and bespoke joinery. Here’s how they compare:
| Factor | Off-the-Shelf (e.g. Bunnings) | Custom / Trade-Supply |
|---|---|---|
| Vanity cost | $300 – $1,200 | $1,500 – $5,000+ |
| Lead time | Same-day pickup | 4–10 weeks |
| Durability | Moderate (flatpack construction) | High (solid construction, custom fit) |
| Warranty | 1–2 years typical | 5–10 years from manufacturer |
| Design flexibility | Limited to standard sizes | Any size, material, or configuration |
| Best for | Rentals, budget renos, quick turnarounds | Forever homes, unusual layouts, premium finishes |
The verdict: Off-the-shelf products are ideal for budget-conscious renovations where speed and cost are the priorities. But for a bathroom you’ll use every day for the next 15–20 years, the durability and design flexibility of custom or trade-supply products often delivers better long-term value. The upfront cost difference on a vanity, for example, can be $1,000–$3,000, but the custom unit typically lasts three to four times longer.
At Jonathan Homes, we work with both options depending on our clients’ budgets and goals. We’ll always be upfront about where it makes sense to invest in premium products and where an off-the-shelf option will perform just as well. That’s part of the custom home builder approach: tailoring the build to your specific needs, not a one-size-fits-all formula.
What Adds the Most Value to Your Bathroom (and What to Avoid)
Not every dollar you spend on a bathroom renovation delivers the same return. Whether you’re renovating with resale in mind or simply want to make smart choices for a home you’ll live in for years, here are the upgrades that deliver the most impact:
| Upgrade | Approximate Cost | ROI / Impact |
|---|---|---|
| Walk-in shower (replacing bathtub) | $3,000 – $6,000 | High: appeals to most buyers, adds perceived luxury |
| Double vanity | $2,000 – $5,000 | High: strong selling point for family homes |
| Underfloor heating | $800 – $2,000 | Moderate: comfort upgrade, low running cost |
| Floor-to-ceiling tiling | $2,500 – $5,000 | High: modern look, easier maintenance |
| Heated towel rail | $300 – $800 | Low cost, high perceived value |
| Frameless glass shower screen | $800 – $2,500 | High: makes small bathrooms feel larger |
What to Avoid
Highly patterned or trend-driven tiles. Bold geometric patterns and bright colours date quickly. Neutral, large-format porcelain or ceramic tiles in matte finishes have the longest visual lifespan and appeal to the widest range of buyers.
Cheap tapware. Budget mixer taps ($50–$100) have a high failure rate within 3–5 years. Spending $200–$400 on quality tapware from a reputable brand (Caroma, Phoenix, Methven) avoids costly replacements and potential water damage from leaking seals.
Skipping proper ventilation. A bathroom without adequate exhaust ventilation will develop mould, regardless of how well it’s waterproofed. Budget $300–$600 for a quality exhaust fan ducted to the exterior, not just into the roof cavity.
DIY waterproofing. This one is worth repeating: waterproofing must be done by a licensed waterproofer in NSW. DIY waterproofing is illegal for wet areas, voids your home insurance, and is the single most common cause of bathroom renovation failures. It’s never worth the saving.
Flooring: Why Porcelain Wins
For wet-area flooring, matte porcelain tiles are the clear winner. They’re denser and less porous than ceramic tiles, making them more resistant to moisture absorption. They’re available in large formats (600×600mm or 600×1200mm) that reduce grout lines and simplify cleaning. Critically, matte finishes also provide better slip resistance than polished surfaces, which is an important safety consideration in households with children or older family members.
Budget $50–$90 per square metre for quality porcelain tiles and $60–$100 per square metre for professional installation including adhesive and grouting.
Colour and Lighting: The Details That Matter
Warm white tones (think soft whites, warm greys, and natural stone palettes) are the most universally flattering and create a sense of space in smaller Sydney bathrooms. Cool whites can feel clinical under artificial light, so if you’re drawn to a cooler palette, pair it with warm-toned LED downlights (3000K colour temperature) to balance the feel.
Natural light makes the biggest difference to how a bathroom feels. If your bathroom has a window, orient your vanity mirror to capture as much natural light as possible. For windowless bathrooms, a well-positioned skylight or solar tube can transform the space. Budget $1,500–$4,000 installed.
How Long Does a Bathroom Renovation Take in Sydney?
Timelines depend on the scope of work and whether you encounter any surprises during demolition. As a general guide for Sydney renovations:
Cosmetic refresh: 1–2 weeks
Standard full renovation (same layout): 3–5 weeks
Premium renovation with layout changes: 5–8 weeks
These timelines assume your materials are ordered and available before demolition begins. The single biggest cause of bathroom renovation blowouts in Sydney is fixture and tile supply delays, particularly for imported products. We always recommend selecting and ordering all products, fixtures (known in the industry as PC items or prime cost items), and tiles before demolition day. Having everything on site or confirmed for delivery means your trades can work continuously without downtime waiting for materials.
How to Get an Accurate Bathroom Renovation Quote
The quality of your quote depends on the quality of your brief. Before you contact a builder, have a clear idea of your scope (cosmetic, standard, or premium), your must-haves versus nice-to-haves, your budget range (including contingency), and any fixtures or tiles you’ve already selected. For advice on evaluating builders, see our guide to choosing the right builder.
A reputable builder will provide a detailed, itemised quote, not a one-line estimate. At Jonathan Homes, our quotes break down every cost category so you can see exactly where your money is going. We offer fixed-price contracts with guaranteed timelines, which means the price we quote is the price you pay. No surprises, no variations unless you request changes.
What to Look for in a Quote
Your quote should clearly separate labour costs by trade (plumber, electrician, tiler, waterproofer), material costs itemised by category, a provisional sum or allowance for PC items (fixtures you haven’t finalised yet), demolition and waste removal, waterproofing as a separate line item (not bundled into tiling), and a stated contingency amount or percentage.
If a quote bundles everything into a single number with no breakdown, that’s a red flag. You need to be able to compare quotes on a like-for-like basis, and that’s only possible when you can see the individual components.
