How much does a bathroom renovation cost in Australia?

A standard full bathroom renovation costs $15,000-$35,000. Cosmetic, layout-kept jobs run $8,000-$15,000, and premium work $35,000-$60,000+. The HIA puts the national average actually spent at $26,747. Here is where the money goes - and the one decision that moves the price most.

The headline ranges - and what scope they describe

Bathroom pricing has a quiet trap: "budget" figures from marketplaces describe cosmetic, like-for-like work, while renovator-quoted full strip-outs and HIA actual-spend data cluster much higher. Both are real - they are just pricing different jobs. We label which is which.

Cosmetic / budget

$8,000-$15,000

Layout unchanged, like-for-like fixtures (hipages, via Canstar and Savings.com.au). A simple renovation of a small bathroom sits at $10,000-$15,000 on Service.com.au's figures.

Standard / mid-range

$15,000-$35,000

Full strip-out renovation (hipages). Service.com.au calls $15,000-$30,000 the range most people budget for; Mertico's 2025 guide gives $15,000-$25,000.

Premium

$35,000-$60,000

Premium tier usually means layout change, relocations and high-end fixtures (Canstar / Three Birds Renovations; CAP Bathrooms gives $35,000-$80,000+).

Luxury custom

$60,000+

Fully custom work with structural change and designer fixtures. Separately, one publisher puts a small bathroom full renovation at $20,000-$27,000 (Yellow Pages) - far above Service.com.au's $10,000-$15,000 simple small-bathroom figure, because it describes a full renovation rather than a simple layout-kept job. We publish both with their scope labels; they are never averaged.

Size helps less than you would expect

A small bathroom or ensuite costs less than a large one, but not in proportion to its floor area - the same trades still visit, the same waterproofing rules apply, and the toilet, basin and shower cost about the same whatever the size of the room (Service.com.au). Typical sizes: an ensuite is 3-5 m² of floor, a main bathroom 6-10 m². Per-m² cross-checks run $2,300-$4,600/m² (hipages and ServiceSeeking, via RenovationCalculator.au), with smaller rooms at the top of that band because fixed costs dominate.

Actual quotes vary by scope more than by postcode: Service.com.au's published full-renovation quotes over the 12 months to October 2026 had a median of $16,500, with the middle half between $4,500 and $25,000 - and the source itself warns some of those quotes are labour-only.

Where the money goes - line by line

Cross-checked ranges for each part of a full renovation. Labour is typically 40-60% of the total job.

Line itemTypical rangeNotes
Demolition / strip-out$800-$3,000A straightforward strip-out is usually $500-$1,500; the wider band covers difficult access and disposal.
Plumbing (rough-in + fit-off, layout kept)$1,500-$5,000Plumbers charge about $100-$150/hr. Moving fixtures is extra - see drivers below.
Electrical$600-$4,000Densest overlap across sources is $800-$2,500. Electricians run about $70-$95/hr plus a call-out.
Waterproofing$700-$1,500Allow up to $3,000 in Sydney or for large wet rooms. Must be done to AS 3740 - see licensing below.
Tiling (floor + walls, supply + install)$2,500-$9,000Room size and tile choice drive this more than any other line; floor-to-ceiling tiling and stone sit at the top.
Vanity / cabinetry$300-$6,000+Budget prefab $300-$700, mid-range $800-$2,500, high-end $3,000-$6,000+ (Service.com.au fixture table).
Toilet$150-$3,000+Budget $150-$500, mid $600-$1,200, high-end $1,300-$3,000+.
Bath$300-$8,000+Acrylic $300-$800, freestanding mid-range $1,000-$2,500, stone or cast iron $3,000-$8,000+.
Shower screen$400-$4,000+Framed $400-$800, semi/frameless $900-$1,800, custom frameless $2,000-$4,000+.
Tapware$100-$3,000+Budget $100-$300, mid $400-$1,000, designer $1,100-$3,000+.

A worked example - and how to read it

Our calculator prices a 6 m² main bathroom, mid-range tier, layout kept, no bath, frameless screen, 22 m² of tiling: demolition $1,500 + plumbing $3,000 + electrical $1,400 + waterproofing $1,100 + tiling $3,080 + fixtures $4,600 = about $14,700, within a $9,700-$23,700 range. That point sits at the bottom of the standard band - correctly, because the example keeps the layout and skips the bath. Add a freestanding bath and it rises by about $1,750; move one fixture and it rises by about $3,250. It is also below the HIA average spend of $26,747, because HIA actuals include the layout changes, baths and premium selections this example leaves out.

What drives the price

1. Moving plumbing

The #1 controllable driver: +$1,500-$5,000 or more (Service.com.au). Moving the toilet or shower - or converting a bath to a walk-in shower - is what pushes a small bathroom out of the simple band toward the middle tier.

2. Fixture tier

The widest swing in the budget. Fixtures and fittings are 20-35% of a small standard bathroom's cost, and the gap between budget and designer selections is measured in tens of thousands across a whole room.

3. Tiles and tiled extent

Tiles are 15-25% of a typical budget. Floor-to-ceiling tiling, large-format tiles, mosaics and natural stone all push the tiling line toward its $9,000 top.

Structural change - avoiding it is the key budget discipline; it also triggers permits and approvals (allow roughly $700 for a council/building permit, $200-$1,000 for an engineer's report and up to $1,000 for home warranty insurance where required - single-source figures, treat as allowances).
What the strip-out finds - water damage and rot hidden behind tiles are a named cost risk. One published Sydney case budgeted $15,000 and finished at $22,000 after water damage was found - an illustration, not a statistic. Hold a contingency; we do not publish a percentage, because no source we checked quantifies one.
Access and location - an upstairs apartment with strata hours and lift rules costs more than a ground-floor house bathroom. On-site work usually takes 1-3 weeks; moving plumbing, big tiling areas and hidden damage add time.

Licensing and compliance - the rules that actually bite

Waterproofing is licensed work

Wet-area waterproofing must meet the National Construction Code, which accepts the NCC wet-area provisions or AS 3740 (Waterproofing of domestic wet areas), and you should ask for a waterproofing certificate on completion. In NSW and Queensland, waterproofers must be licensed; in Queensland waterproofing is its own QBCC licence class, and a waterproofing certificate (Form 43 or Form 12) is required when the work exceeds $3,300. Plumbing and electrical work must always be done by licensed tradespeople - in NSW a licence is needed for that specialist work whatever the job costs.

Contract thresholds by state

  • Queensland (QBCC): building work over $3,300 (labour + materials) must be done by a QBCC-licensed contractor - a full bathroom renovation is always over this threshold.
  • New South Wales: residential building work over $5,000 (inc. GST) needs a licensed contractor and a written contract; over $20,000 it also needs Home Building Compensation cover, with proof shown before a deposit is taken. Deposits are capped at 10%.
  • Victoria: two different thresholds apply and should not be conflated - domestic building work over $10,000 must be done by a Registered Building Practitioner, and Home Warranty insurance applies above $20,000 for contracts signed on or after 1 July 2026. Check the current Building and Plumbing Commission rules before you sign.
