What Does a Bathroom Renovation Really Cost in Sydney? Your 2026 Price Guide
The bathroom renovation cost in Sydney depends heavily on the size of the bathroom, the quality of fittings chosen, and whether the renovation involves moving plumbing. Most Sydney homeowners spend between $8,000 and $35,000 for a standard bathroom renovation, with full luxury renovations in upmarket suburbs reaching $50,000 or more.
This guide breaks down what drives the cost, what you can expect to pay for different renovation scopes, and how to get a fair price from a licensed Sydney tradesperson.
What Does a Bathroom Renovation Include?
A standard bathroom renovation in Sydney typically involves demolition of the old bathroom, waterproofing, tiling, installation of new fixtures and fittings, and plumbing and electrical work. The scope varies significantly between a “cosmetic refresh” and a full structural renovation.
A cosmetic refresh might involve replacing the vanity, toilet repairs, tapware, and mirror without touching the tiles or plumbing layout. This is the most affordable option and can transform the look of a bathroom for $4,000 to $8,000 without a full strip-out.
A full renovation involves stripping the bathroom to the frame, installing new waterproofing membrane, relaying tiles, installing new plumbing fixtures, and updating electrical (lighting, exhaust fans). This is the most common type of bathroom renovation and is necessary when existing tiles are cracked, grout is discoloured beyond cleaning, or the layout is being changed.
Licensed trades required in a bathroom renovation include a plumber (for all water supply and drainage connections), an electrician (for light fittings, exhaust fans, and heated towel rails if applicable), and a waterproofer where the shower and wet areas are being retiled. In NSW, all licensed tradespersons must hold current licences. You can check credentials via the NSW Government trade licences register.

Request a CallbackWhat Factors Drive Up the Cost of a Bathroom Renovation?
Several variables can push a bathroom renovation budget significantly higher than the base estimate. Understanding these factors before you commit to a renovation scope helps you budget accurately and avoid mid-project cost blowouts.
Tiles and Material Selection
Tiles are one of the biggest cost levers in a bathroom renovation. Budget porcelain or ceramic tiles start around $25 to $50 per square metre. Mid-range tiles in the $60 to $120 range are the most common choice for Sydney renovations. Premium large-format stone-look tiles or imported Italian porcelain can reach $200 to $400 per square metre or more. For a standard 7m² bathroom, going from budget to premium tiles can add $2,000 to $5,000 to the total cost.
Fixture and Fitting Quality
Vanity units range from $350 for a flat-pack model to $4,000 for a custom-built timber vanity. Toilet suites vary from $400 for a standard close-coupled unit to $2,500 for a wall-faced or Japanese-style bidet toilet. Tapware and shower heads can cost anywhere from $80 to $1,500 per item. Choosing mid-range fixtures throughout a standard bathroom typically adds $3,000 to $6,000 compared to builder’s grade options.
Moving Plumbing
Changing the layout of a bathroom by moving the toilet, shower, or vanity to a new position requires a licensed plumber to relocate waste pipes and water supply lines. In homes with concrete slab construction, this involves core drilling through the slab to create new penetrations, which adds significant time and cost. Moving plumbing in a suspended timber floor home is more straightforward. In both cases, budget at least $3,000 to $8,000 extra for any layout change.
Asbestos and Hazardous Materials
Homes built before 1987 in Sydney suburbs such as Blacktown, Penrith, Fairfield, and Canterbury often contain asbestos in bathroom sheeting (fibro or Hardiflex walls, floor adhesives, or ceiling tiles). Before any demolition work can begin, a licensed asbestos assessor must test the material and, if positive, a licensed removalist must handle the removal. Budget $800 to $3,000 for asbestos testing and removal in older Sydney homes.
Waterproofing Standards
NSW building regulations require bathroom waterproofing to comply with AS 3740-2010. A properly installed waterproofing membrane from a licensed applicator costs $500 to $1,200 for a standard bathroom. Cutting corners on waterproofing is one of the most common causes of expensive damage in bathroom renovations, as leaks through inadequate membranes cause structural damage to floors and walls over time.
How Much Does the Plumbing Cost in a Bathroom Renovation?
Plumbing is a significant proportion of the total bathroom renovation cost in Sydney. For a standard bathroom renovation where the layout is not changing, expect to pay $2,500 to $5,500 for all plumbing work. This covers disconnection and removal of old fittings, connection of new tapware, shower, toilet, and vanity waste.
If the renovation involves moving any plumbing, expect the plumbing cost to increase to $5,000 to $12,000 depending on the extent of relocation, wall type, and whether concrete cutting is required. All plumbing work in NSW must be carried out by a licensed plumber, who is required to issue a Certificate of Compliance for water supply and drainage work.
A critical step that is sometimes overlooked is checking the condition of existing waste pipes before tiling begins. Older Sydney homes in suburbs like Hurstville, Strathfield, or Burwood may have cast iron or clay waste pipes under the floor slab that are cracked, partially blocked, or deteriorated. Discovering this problem after tiling has been completed requires removal of new tiles to access the pipes, creating expensive rework. Our article on pipe relining costs in Sydney explains when pipe relining is a viable alternative to full pipe replacement.

How Long Does a Bathroom Renovation Take in Sydney?
A standard bathroom renovation in Sydney takes 2 to 4 weeks from start to finish. The timeline breaks down roughly as follows: demolition and preparation (1 to 2 days), waterproofing and drying time (2 to 3 days, as the membrane must cure before tiling), tiling (1 to 3 days depending on size and tile format), fixture and fitting installation (1 to 2 days), and final inspection and sealing (1 day).
Delays are common and are usually caused by tile delivery lead times, plumbing or electrical rough-in inspections requiring re-scheduling, or weather delays affecting external waterproofing. For heritage homes or complex renovations in Sydney’s Inner West or Eastern Suburbs, allow up to 6 weeks for a full renovation involving structural changes.
During the renovation, the bathroom will be completely out of use. In a single-bathroom home, this is a significant inconvenience. Discuss with your contractor whether phased work or a temporary bathroom facility is appropriate, particularly for families with young children.
How to Get a Fair Quote for Your Sydney Bathroom Renovation
The most important step is to get at least three itemised quotes from licensed Sydney contractors. A quote should specify: scope of demolition, waterproofing product and warranty, tiling labour and material allowances, plumbing and electrical inclusions, fixture and fitting allowances (or confirm if supply-only is separate), and payment schedule.
Be sceptical of quotes that are significantly lower than others without explanation. Underquoting is a known problem in the Sydney renovation industry, where contractors win the job with a low price and then present variations and extras once work is underway. A detailed scope of works attached to the quote provides legal protection if disputes arise.
If the total value of building work exceeds $5,000 in NSW, the contractor must hold a current contractor licence and provide a written contract. For work valued above $20,000, the contractor must also provide Home Building Compensation Fund cover. These are legal requirements under the Home Building Act 1989, not optional extras.

A standard full bathroom renovation in Sydney costs $15,000 to $25,000 for a 5 to 9 square metre bathroom. Small bathroom or ensuite renovations start around $8,000 to $15,000. Luxury renovations with premium fittings and materials can reach $35,000 to $60,000 or more. Cosmetic refreshes (new fixtures, no tiling) cost $4,000 to $8,000.
Do I need council approval for a bathroom renovation in Sydney?
Most standard bathroom renovations do not require a Development Application (DA) in NSW, as they fall under exempt development provisions. However, if you are moving the bathroom location, altering external walls, or working in a heritage-listed property, council approval may be required. Always check with your local council before starting work.
How long does a bathroom renovation take?
A standard bathroom renovation in Sydney typically takes 2 to 4 weeks from start to finish. Complex renovations involving layout changes, structural work, or heritage homes may take 4 to 6 weeks. Delays due to product lead times and inspection scheduling are common.
Do I need a licensed plumber for a bathroom renovation in Sydney?
Yes. All plumbing and drainage work in NSW must be carried out by a licensed plumber who holds a current NSW Fair Trading licence. The plumber must also issue a Certificate of Compliance for any water supply and drainage work. Using an unlicensed person for plumbing in a bathroom renovation is illegal and may void your home insurance.
What is the cheapest way to renovate a bathroom in Sydney?
The cheapest approach is a cosmetic refresh: replace the vanity, toilet suite, tapware, shower head, and accessories without touching the tiles or plumbing layout. This can cost $4,000 to $8,000 and significantly update the look of a bathroom. Supply your own fixtures (purchased separately) and engage a plumber only for disconnection and connection of fittings to reduce costs further.
Can I claim bathroom renovation costs on tax?
For owner-occupied homes, bathroom renovation costs are generally not tax-deductible. For investment properties, the situation is more nuanced: ongoing repairs are typically deductible, while capital improvements are depreciated over time. Seek advice from a registered tax agent familiar with Australian property taxation rules.
How do I find a reliable bathroom renovation contractor in Sydney?
Ask for references from recent jobs in your suburb, check that the contractor holds a current NSW contractor licence via the NSW Fair Trading online register, and get at least three itemised quotes. Membership of industry bodies such as the HIA (Housing Industry Association) or Master Builders Association provides additional accountability, though it is not mandatory.
