How Much Does a Bathroom Renovation Cost in Australia? (2026 Prices)

A bathroom renovation in Australia typically costs $15,000–$30,000 for a standard full renovation. A budget refresh starts around $8,000–$15,000, and a high-end or large bathroom can run $30,000–$45,000+. Tiling, waterproofing, plumbing changes and fixtures are the biggest cost drivers.

How much does a bathroom renovation cost?

• Budget refresh (re-tile, new fixtures, same layout): $8,000–$15,000
• Standard full renovation: $15,000–$30,000
• Premium / large / layout change: $30,000–$45,000+

A bathroom involves several trades — waterproofer, tiler, plumber, electrician and sometimes a builder — which is why even a small room adds up.

What affects the price

• Layout changes: moving the toilet, shower or vanity means new plumbing and waterproofing — the single biggest cost jump.
• Tiling: floor-to-ceiling tiling, large-format or feature tiles add labour and materials.
• Fixtures and fit-out: tapware, vanity, shower screen and toilet range from builder's-basic to premium.
• Waterproofing: mandatory to AS 3740 and non-negotiable on price.
• Hidden issues: rotten substrate, old pipes or asbestos discovered on strip-out add cost.

How to get an accurate bathroom quote

Because multiple trades are involved, the most reliable quote is itemised by element — strip-out, plumbing, waterproofing, tiling, fixtures and making-good — with a clear allowance for fixtures so you can adjust the spec. Always get the scope and exclusions in writing. A tradie or builder using Insta Quotes can build that itemised quote on-site in minutes instead of days.
