I still remember the day I decided my bathroom had had enough. The tiles were cracked, the vanity looked like it had survived the 1980s, and the shower pressure? Let’s just say it was more “gentle mist” than “revitalising waterfall.” Like many Melburnians, I started with a simple question: how much does a bathroom renovation actually cost in Melbourne? What began as a quick Google search turned into a deep dive through quotes, trades, and fixture showrooms. So in this guide, I’ll share what I learned — the real numbers, not the “TV renovation show” versions — to help you plan your dream bathroom without blowing the budget.

Overview: Why Melbourne Bathroom Costs Vary

Here’s the thing: no two bathrooms are the same. Renovating a 3m² apartment ensuite in Southbank costs vastly different to revamping a heritage bathroom in Kew. Prices vary based on size, materials, layout changes, and property type. Even two identical designs can have wildly different quotes depending on site access, existing plumbing, and builder experience.

Melbourne also has one of the most diverse housing stocks in Australia — from modern townhouses to 100-year-old terraces — so builders often need to adjust their approach to match your home’s quirks (and surprises hiding behind the walls).

Average Bathroom Renovation Costs (2025 Figures)

In 2025, the average bathroom renovation cost in Melbourne sits between $25,000 and $40,000 for most homeowners. However, the range is broad depending on your goals:

• Budget/basic bathroom: $15,000 – $25,000
• Mid-range renovation: $25,000 – $40,000
• High-end bathroom: $40,000 – $70,000+

Let’s be honest—renovations on the cheaper side often involve keeping existing plumbing locations, selecting off-the-shelf vanities, and using standard ceramic tiles. On the higher end, expect custom cabinetry, premium stone finishes, and designer fixtures that transform the space into a luxurious retreat.

Cost Breakdown: Where Your Money Goes

Here’s how the average bathroom budget usually splits out:

• Demolition & rubbish removal: $1,000 – $2,000
• Plumbing rough-in & fit-off: $5,000 – $8,000
• Electrical work & lighting: $1,500 – $3,000
• Tiling & waterproofing: $6,000 – $10,000
• Cabinetry & vanity: $2,000 – $4,000
• Shower, toilet, bath & fittings: $3,000 – $7,000
• Painting & finishes: $800 – $1,500
• Labour & project management: $4,000 – $7,000
• Contingency (unexpected works): 8–10% of total budget

Remember: older homes often need extra work for structural repairs, outdated plumbing, or uneven floors. It’s smart to add a 10% buffer for surprises that pop up once demolition begins.

Realistic Cost Examples

Example A: Small Apartment Ensuite (3m²)

• Basic fixtures, single vanity, and wall-hung toilet
• Mid-range tiles and lighting upgrades
• Estimated cost: $18,000 – $25,000

Example B: Mid-Range Family Bathroom (6m²)

• Full gut and replace with modern tiles, vanity, bath, and frameless shower
• Some minor plumbing changes for better layout
• Estimated cost: $30,000 – $38,000

Example C: Luxury Heritage Bathroom (8m²+)

• Custom marble vanity, freestanding bath, underfloor heating
• Restored decorative mouldings and premium lighting
• Estimated cost: $45,000 – $70,000+

These figures assume professional labour, quality materials, and compliance with Australian waterproofing standards.

Key Factors That Affect Price

• Size of the bathroom: Bigger spaces require more tiles, more fixtures, and longer labour time.
• Layout changes: Moving plumbing or drainage points adds complexity and cost.
• Age of property: Older Melbourne homes may need structural or electrical upgrades.
• Materials & finishes: Natural stone, brushed brass, and handmade tiles cost more than standard fittings.
• Custom joinery: A bespoke vanity or mirror cabinet can cost several thousand dollars more than off-the-shelf options.
• Builder quality: Experienced renovation specialists charge more but deliver smoother, faster projects.
• Access: Tight inner-city terraces or upper-storey bathrooms can increase labour time.
• Permits: Most internal bathroom renos don’t require planning permits, but you’ll still need a building permit if structural changes occur.

Different Types of Bathroom Renovations

1. Cosmetic Refresh (2–3 weeks)

Perfect if your layout works but the finishes are tired. Think re-tiling, repainting, and fixture replacements. Costs range from $10,000 – $20,000.

2. Mid-Range Renovation (4–6 weeks)

Full strip-out with new waterproofing, tiles, vanity, and modern lighting. Costs typically fall between $25,000 – $40,000.

3. Structural or Luxury Remodel (6–10 weeks)

Includes layout changes, new plumbing routes, and custom joinery. Expect $40,000 – $70,000+ depending on scope and materials.

Timeline: How Long It Takes

Here’s a realistic timeline for a standard Melbourne bathroom renovation:

• Planning & design: 2–4 weeks
• Demolition: 2–4 days
• Plumbing & electrical rough-in: 3–5 days
• Waterproofing & tiling: 7–10 days
• Painting & fit-out: 4–6 days
• Final inspection: 1–2 days

All up, most bathroom renovations in Melbourne take 3–6 weeks once construction begins — but allow another month for design, material selection, and trades scheduling before that.

How to Save Without Sacrificing Quality

• Keep the layout: Avoid moving toilets, showers, or drains unless absolutely necessary.
• Shop smart: Many mid-range brands offer designer looks without the designer price tag.
• Mix high and low: Combine statement tiles on feature walls with standard ones elsewhere.
• Reuse good bones: Keep a solid bathtub or existing cabinetry if it’s in great condition.
• Hire reputable professionals: DIY waterproofing mistakes cost far more to fix than to do right the first time.
• Get multiple quotes: Always compare inclusions carefully, not just bottom-line prices.
• Plan ahead: Order tiles and fixtures early to avoid rush fees and supply delays.

Saving doesn’t mean cutting corners — it’s about prioritising where your dollars make the biggest visual and functional impact.

FAQ: Common Bathroom Renovation Questions

Do I need a building permit?

Only if your renovation involves structural changes or moving plumbing through new walls/floors. Cosmetic updates usually don’t require one, but always check with your builder or surveyor.

What’s the most expensive part of a bathroom renovation?

Plumbing and tiling often make up 50% of the total cost, especially when relocating fixtures or using premium materials.

Can I renovate just one section?

Yes — updating a vanity or shower zone can refresh the space for a fraction of a full remodel, typically $8,000 – $15,000.

How do I choose the right builder?

Look for licensed renovators who specialise in bathrooms, have recent local references, and provide fixed-price quotes with clear inclusions.

Will a new bathroom add value to my home?

Absolutely. In Melbourne’s competitive property market, a stylish, functional bathroom can increase resale appeal and overall property value by tens of thousands of dollars.

Final Thoughts & Next Steps

When planning your Melbourne bathroom renovation, the magic number for most homeowners sits around $25,000–$40,000. The key is balancing style, function, and smart spending. Invest in quality waterproofing, good lighting, and timeless design — these will outlast trends and add value to your home.
