How to Quote a Bathroom Renovation in Australia

Learn how to quote a bathroom renovation accurately. Covers demolition, waterproofing, tiling, plumbing, fixtures, and labour — with real costs and tips for Australian tradies.

What to Include in a Bathroom Renovation Quote

A professional bathroom renovation quote should cover demolition and waste removal, waterproofing (AS3740 compliance), tiling (floor and walls), plumbing (rough-in and fixtures), electrical (lighting, exhaust fan, heated towel rail), fixtures (vanity, toilet, shower screen, tapware), and any structural or gyprocking work. Missing any of these can lead to costly variations mid-job.

Typical Costs for a Bathroom Reno in 2026

A standard bathroom renovation in Australia costs between $15,000 and $35,000 depending on size, finishes, and location. Budget bathrooms start around $10,000–$15,000, mid-range renovations sit at $20,000–$30,000, and high-end bathrooms with premium tiles and fixtures can exceed $40,000. Always quote materials at current prices — don't rely on last month's pricing.

How to Price Materials Accurately

The biggest quoting mistake is using outdated material prices. Tile prices, adhesive, waterproofing membrane, and fixture costs change regularly. Use QuoteMate to pull real-time pricing from Bunnings and Mitre 10 so your quotes always reflect today's costs. Include a 10% waste factor on tiles and adhesive.

Labour Pricing Tips

Break labour into trades: demolition (1–2 days), plumbing rough-in (1 day), waterproofing (1 day + drying), tiling (2–4 days), plumbing fit-off (1 day), electrical (half day), and finishing. Quote each trade separately or as a total. Don't forget to include your margin on sub-contracted trades.

Common Quoting Mistakes to Avoid

1. Forgetting waterproofing compliance costs. 2. Underestimating demolition and waste removal. 3. Not accounting for plumbing relocations. 4. Using old tile prices. 5. Not including a contingency for hidden issues (rotten framing, asbestos). Add a 5–10% contingency line item for renovations.
