How Much Does a Bathroom Renovation Cost in Sydney in 2026?

What Does a Bathroom Renovation Actually Cost in Sydney in 2026?

If you’ve started researching bathroom renovation costs in Sydney, you’ve probably noticed the range is enormous. One website says $10,000, another says $50,000, and you’re left wondering which number applies to your bathroom.

The truth is, there’s no single answer. The cost depends on your bathroom’s size, the condition of existing plumbing and waterproofing, the quality of fixtures you choose, and how much structural work is involved. But what we can do is break down the real numbers — based on current Sydney trade rates and material costs — so you can set a realistic budget before picking up the phone.

This guide covers everything from a basic refresh to a full high-end fit-out, with line-by-line cost breakdowns for every major trade and material category.

Bathroom Renovation Cost Tiers: Small, Mid-Range, and High-End

The easiest way to understand Sydney bathroom renovation pricing is to think in tiers. Each tier reflects different fixture quality, layout complexity, and finish levels.

Budget / Small Bathroom Renovation ($12,000–$18,000)

This covers a straightforward renovation of a small bathroom (roughly 3–5 m²) with no major layout changes. You’re replacing fixtures, re-tiling, and refreshing the space without moving plumbing or walls.

• Standard ceramic tiles (floor and walls)
• Basic vanity unit and mirror cabinet
• Entry-level tapware and shower mixer
• New toilet (back-to-wall or close-coupled)
• Acrylic shower screen
• Full waterproofing and certification

Mid-Range Renovation ($20,000–$35,000)

The most common tier for Sydney homeowners. This includes a medium-sized bathroom (5–8 m²) with upgraded fixtures, possible layout adjustments, and higher-quality finishes throughout.

• Porcelain or large-format tiles
• Stone-top or timber vanity
• Brushed nickel, matte black, or brass tapware
• Frameless glass shower screen
• Wall-hung toilet
• Heated towel rail
• LED mirror or backlit shaving cabinet

High-End / Luxury Renovation ($40,000–$65,000+)

For larger bathrooms, ensuites with freestanding baths, or full gut-and-rebuild projects. This tier often involves structural changes, custom joinery, underfloor heating, and premium imported materials.

• Natural stone or designer porcelain tiles
• Freestanding bath
• Custom vanity with stone benchtop
• Niche shelving and recessed storage
• Underfloor heating
• Smart toilet or bidet seat
• Full rewiring and new lighting design

Cost Breakdown by Trade and Material

Understanding where your money goes helps you make informed decisions about where to spend and where to save. Here’s a line-by-line breakdown of the major cost components for a mid-range Sydney bathroom renovation in 2026.

Demolition and Waste Removal

Stripping out an existing bathroom typically costs $1,500–$3,000. This includes removing old tiles, fixtures, and vanities, plus skip bin hire and waste disposal. Asbestos testing may add $300–$500 if your home was built before 1990.

Waterproofing

Waterproofing is one of the most critical — and most regulated — parts of any bathroom renovation. In NSW, waterproofing must comply with AS 3740 and be carried out by a licensed waterproofer. Expect to pay $1,200–$2,500 depending on the bathroom size and whether the shower is a hobless (step-free) design.

Plumbing

If you’re keeping the existing layout, plumbing costs typically run between $2,500 and $5,000. Moving a toilet, adding a second basin, or relocating the shower will push costs toward $5,000–$8,000. Hot water system upgrades are additional.

Tiling

Tiling labour in Sydney ranges from $65 to $120 per square metre, depending on tile size, pattern complexity, and whether you’re tiling full-height walls. Tiles themselves vary enormously — budget $30–$60/m² for standard porcelain, $80–$200/m² for large-format or natural stone. A mid-range bathroom typically requires 25–40 m² of tiling.

Electrical

New lighting, exhaust fan installation, heated towel rail connection, and power points cost between $800 and $2,000. Underfloor heating adds $1,000–$2,500 for supply and installation.

Fixtures and Fittings

This is where personal taste has the biggest impact on budget. A basic set of fixtures (toilet, vanity, tapware, shower screen, mirror) starts around $2,000–$3,500. Mid-range selections typically land between $4,000 and $8,000. Premium brands and custom pieces can exceed $15,000.

The biggest budget blowouts we see aren’t from expensive tiles — they’re from homeowners not accounting for waterproofing, waste removal, and compliance costs upfront. A detailed, itemised quote prevents 90% of surprises.

Hidden Costs That Catch Sydney Homeowners Off Guard

Even with a solid budget, there are costs that frequently surprise first-time renovators. Being aware of these upfront helps you build in a contingency buffer of 10–15%.

• Asbestos removal: Common in pre-1990 homes. Testing costs $300–$500; removal can add $1,500–$5,000 depending on the extent.
• Structural repairs: Rotten floor joists, damaged framing, or termite damage uncovered during demolition. Budget $1,000–$4,000 for unexpected structural work.
• Council and strata approvals: Strata properties often require a by-law or building management committee approval. Some councils require a Complying Development Certificate for significant plumbing changes.
• Temporary facilities: If you only have one bathroom, you may need a portable toilet or temporary shower setup during the renovation ($200–$500).
• Delivery and access fees: Multi-storey homes, narrow laneways, or apartment buildings with restricted lift access can increase material delivery costs by $300–$800.

Strata-Specific Considerations

If you’re renovating in a strata building, expect additional costs and timeframes. Most strata schemes require a waterproofing report from a licensed certifier, and some mandate specific tradesperson insurances. The approval process alone can take 4–8 weeks, so factor this into your timeline.

How to Save Money Without Sacrificing Quality

Trimming your bathroom renovation budget doesn’t mean accepting a substandard result. There are smart ways to reduce costs while maintaining a professional finish.

1. Keep the existing layout. Moving plumbing is one of the single most expensive changes. If your current layout works, keeping drains and water points in place can save $2,000–$5,000.
2. Choose tiles strategically. Use feature tiles sparingly — a single accent wall or niche — and use a more affordable complementary tile for the remaining surfaces.
3. Supply your own fixtures. Some renovators offer a labour-only rate if you source your own vanity, tapware, and toilet. This lets you shop sales, clearance stock, or trade-price outlets.
4. Renovate during quieter periods. January through March and mid-winter tend to be slower for Sydney tradies. You may find better availability and occasionally better rates.
5. Bundle projects. If you’re also planning a laundry or kitchen renovation, bundling trades can reduce mobilisation costs and sometimes earn a volume discount.

Where Not to Cut Costs

There are three areas where going cheap will always cost you more long-term:

• Waterproofing: A failed membrane means ripping everything out and starting again. This is not the place to save $500.
• Plumbing: Licensed plumbers cost more than handymen for a reason. Non-compliant plumbing work can void your insurance and create serious water damage.
• Ventilation: A properly sized exhaust fan prevents mould, moisture damage, and paint deterioration. Budget $300–$600 for a quality unit with adequate extraction capacity.

How Long Does a Bathroom Renovation Take in Sydney?

Timeframes depend on scope, but here’s what most Sydney homeowners can expect:

• Budget/small renovation: 2–3 weeks
• Mid-range renovation: 3–5 weeks
• High-end or structural renovation: 5–8 weeks

These timeframes assume materials are pre-ordered and approvals are in place before demolition begins. Delays in tile supply or strata approvals are the most common causes of extended timelines. A good renovator will provide a project schedule with milestones so you know exactly what’s happening each week.

What Affects the Timeline?

Custom vanities and imported tiles often have 4–8 week lead times. If you’ve chosen specialty items, order them before signing a start date. Wet weather can also delay work in bathrooms with exterior walls or windows that need to remain open during waterproofing cure times.

How to Choose the Right Bathroom Renovator in Sydney

Price is important, but the cheapest quote is rarely the best value. Here’s what to look for when comparing Sydney bathroom renovation companies.

Credentials and Licensing

Ensure your renovator holds a current NSW contractor licence. For projects over $5,000 (which includes virtually all bathroom renovations), a licence is legally required. Check their licence status on the NSW Fair Trading website.

What to Look for in a Quote

A professional quote should be fully itemised, breaking down:

1. Demolition and waste removal
2. Waterproofing (including certification)
3. Plumbing labour and materials
4. Electrical labour and materials
5. Tiling labour and tile supply (listed separately)
6. Fixtures and fittings (itemised by product)
7. Painting and finishing
8. Project management and supervision

If a quote is a single lump sum with no breakdown, that’s a red flag. You can’t compare what you can’t see.

Reviews and Portfolio

Check Google reviews, ask for references from recent projects, and review before-and-after photos. Pay attention to how the renovator handles problems in reviews — every project hits a snag, and how it’s resolved matters more than a perfect score.

Frequently Asked Questions

What is the average cost of a bathroom renovation in Sydney in 2026?

The average mid-range bathroom renovation in Sydney costs between $20,000 and $35,000 in 2026. Budget renovations start around $12,000–$18,000, while high-end projects with structural changes and premium materials can exceed $50,000. The final cost depends on your bathroom’s size, the extent of plumbing and electrical work, and the quality of fixtures and tiles you select.

Can I renovate a bathroom in Sydney for under $15,000?

Yes, but it requires a small bathroom (under 4 m²), no layout changes, and budget-tier fixtures and tiles. You’ll still need to pay for proper waterproofing and licensed plumbing — these are non-negotiable. A cosmetic refresh (new vanity, tapware, paint, and resurfaced tiles) can come in under $10,000, though it won’t address underlying waterproofing or plumbing issues.

Do I need council approval to renovate my bathroom in Sydney?

Most standard bathroom renovations — replacing fixtures, re-tiling, and updating waterproofing — don’t require council approval if you’re not changing the building’s footprint or structural elements. However, if you’re altering wet area drainage, moving walls, or the work affects common property in a strata building, you may need a Complying Development Certificate or strata by-law approval. Your renovator should advise you on this before work begins.

How long does a full bathroom renovation take?

A standard mid-range renovation takes 3–5 weeks from demolition to final clean. Budget renovations with no layout changes can be completed in 2–3 weeks. Larger projects involving structural work, custom joinery, or imported materials may take 5–8 weeks. Pre-ordering materials and securing strata approvals before the start date is the best way to avoid delays.

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

Tiling and plumbing are typically the two largest cost items, together accounting for 40–50% of the total budget. Tiling costs are driven by both labour rates ($65–$120/m²) and material costs, especially if you choose large-format or natural stone tiles. Plumbing costs escalate quickly if you’re relocating fixtures or upgrading pipework. Fixtures and fittings are the third major category, with high variability depending on your taste and brand choices.
