A standard full bathroom renovation runs $15,000-$35,000 in Australia; cosmetic jobs $8,000-$15,000, premium $35,000-$60,000+. This calculator builds your estimate line by line - the same way renovators quote - instead of hiding everything in a single per-metre rate.
Tell us the room, the finish level and whether the layout moves. The estimate updates as you go.

The numbers behind the calculator - published Australian ranges, cross-checked across at least two sources each.
$15,000-$35,000
The headline band for a full strip-out renovation of a standard bathroom (hipages; Service.com.au puts the range most people budget for at $15,000-$30,000). The HIA Kitchens & Bathrooms Report 2025 puts the national average actual spend at $26,747 - actuals include layout changes, baths and premium selections that a layout-kept estimate may exclude.

Like-for-like refresh with the layout unchanged (hipages via Canstar and Savings.com.au). A simple renovation of a small bathroom or ensuite also lands at $10,000-$15,000 (Service.com.au).
$35,000-$60,000+
Premium renovations run $35,000-$60,000, and luxury custom work $60,000 and up - usually defined by layout changes, relocations and high-end fixtures (Canstar / Three Birds; CAP Bathrooms).
Shifting a toilet, shower or bath adds $1,500-$5,000 or more (Service.com.au). Keeping every fixture where it is, is the single biggest saving in a bathroom renovation.
A vanity runs $300-$700 at budget tier and $3,000-$6,000+ custom; a bath $300-$800 acrylic or $3,000-$8,000+ in stone or cast iron (Service.com.au fixture table).
The same trades still visit and the same waterproofing rules apply, so cost per m² falls as rooms get bigger: $2,300-$4,600/m² is the hipages cross-check band for typical rooms.
Waterproofing must comply with the National Construction Code / AS 3740, and in NSW and Queensland waterproofers must be licensed - in Queensland it is a dedicated QBCC licence class. Get the waterproofing certificate on completion. Full detail in the guide.
The bathroom guide walks through every line item - demolition, plumbing, tiling, fixtures - with the sources behind each range, plus the licensing rules that apply in your state.
