How Much Does a Bathroom Renovation Cost in Sydney? (2026 Guide)

If you are planning a bathroom renovation in Sydney, one of the first questions you will ask is how much it will cost. The answer depends on the size of your bathroom, the materials you choose, the scope of work involved, and whether you need to make any structural or plumbing changes.

At Fascon Renovations, we have been renovating bathrooms across Sydney for years, and we understand the real costs involved — not just the headline figures. This guide breaks down everything you need to know about bathroom renovation pricing in Sydney for 2026, so you can plan your project with confidence.

Average Bathroom Renovation Cost in Sydney (2026)

A standard bathroom renovation in Sydney typically costs between $15,000 and $35,000, depending on the size of the room, the quality of materials, and the extent of the work. Here is a general breakdown by budget level:

Budget renovation ($12,000 – $18,000): Cosmetic updates such as new tiles, paint, fixtures and a vanity replacement. The existing layout and plumbing stay in place. Ideal for rental properties or a quick freshen-up before selling.

Mid-range renovation ($18,000 – $35,000): A complete strip-out back to the studs with new waterproofing, tiling, fixtures, cabinetry and fittings. This is the most popular option for Sydney homeowners and covers everything needed for a high-quality, long-lasting bathroom.

Premium renovation ($35,000 – $60,000+): A fully custom bathroom with premium materials, designer fixtures, layout changes, underfloor heating, freestanding baths and bespoke joinery. Common in Sydney’s North Shore, Eastern Suburbs and Inner West.

What Drives the Cost of a Bathroom Renovation?

Several factors influence the final price of a bathroom renovation in Sydney. Understanding these will help you make informed decisions and avoid budget blowouts.

Bathroom size: A small ensuite of 3 to 4 square metres will naturally cost less than a large family bathroom of 8 to 10 square metres. However, smaller bathrooms can sometimes cost more per square metre because the same trades and waterproofing are required regardless of size.

Layout changes: Keeping the existing layout is the single biggest way to control costs. Moving the toilet, shower or vanity to a different location requires rerouting plumbing, which can add $2,000 to $5,000 or more to the project. Relocating a toilet is the most expensive because of the waste pipe.

Materials and fixtures: Tiles range from $30 per square metre for basic ceramic through to $200 or more for natural stone or large-format porcelain. Vanities range from $500 off-the-shelf to $5,000 or more for custom joinery. Tapware, shower screens, toilets and accessories all add up quickly.

Waterproofing: Waterproofing is mandatory under the National Construction Code and typically costs between $1,500 and $3,500 depending on bathroom size. This is non-negotiable and must be carried out by a licensed waterproofer with a compliance certificate.

Labour: Labour typically accounts for 40 to 60 percent of the total renovation cost. A standard bathroom renovation requires a plumber, electrician, tiler, waterproofer, carpenter and sometimes a plasterer and painter. In Sydney, licensed plumbers and electricians charge between $80 and $150 per hour.

Hidden Costs to Watch For

Many homeowners underestimate bathroom renovation costs by up to 30 percent because they overlook expenses that only become apparent once work begins. Common hidden costs include:

Asbestos removal — common in pre-1990s Sydney homes, especially in wall sheeting and flooring. Testing and removal can add $1,000 to $3,000. Structural repairs — rotted framing, damaged floor joists or termite damage discovered during strip-out. Ventilation upgrades — older bathrooms often lack adequate exhaust fans, which must be upgraded to comply with current standards. Waste removal — demolition waste removal typically costs $500 to $1,500 depending on the volume. We always recommend setting aside a contingency buffer of 10 to 15 percent of your total budget to cover surprises.

How Long Does a Bathroom Renovation Take in Sydney?

A standard bathroom renovation in Sydney typically takes between 3 and 6 weeks from demolition to completion. The timeline depends on the scope of work, material lead times, and whether any structural changes are involved. Larger or more complex renovations can take 6 to 8 weeks.

We always provide a clear timeline during your free consultation so you know exactly what to expect and can plan around the disruption.

Is a Bathroom Renovation Worth It in Sydney?

A well-executed bathroom renovation is one of the highest-return upgrades you can make to a Sydney home. Updated bathrooms are consistently among the top features buyers look for, and a quality renovation typically adds 50 to 70 percent of its cost to the property’s value. Beyond resale, a new bathroom improves your daily quality of life, reduces maintenance issues, and can lower water and energy bills with modern fixtures.

If you are also considering structural work on your property, such as building or replacing a retaining wall, it often makes sense to coordinate both projects to save on site costs and project management. Our retaining wall builders in Sydney can assess your property alongside your bathroom renovation.
