When you ask a tradie how long a bathroom takes, the honest answer is "depends" and the dishonest one is "two weeks". Both of these are useless. Here's the realistic 2026 Australian bathroom renovation timeline, broken down by week, including the bits that nobody warns you about.
The headline numbers
Across the 3,200 bathroom renovations quoted through Quotefor.au in the last 12 months:
- Refresh tier (no waterproofing reset, fixtures replaced, tiles kept) — 9 to 14 days.
- Full rebuild (strip-out + new waterproofing + new fixtures) — 3 to 5 weeks.
- Premium / wet-room (full rebuild + structural changes + bespoke tile) — 6 to 10 weeks.
- Strata apartment bathroom — add 2 weeks to any of the above for approvals and noise restrictions.
The real week-by-week, full-rebuild tier
Let's do the most common scenario — a full strip-out and rebuild of a 5m² family bathroom in a standalone home.
Week 1: Demolition and rough services
Day 1–2: Floor protection, fixture isolation, demo. The bathroom is reduced to studs and slab/joists. Skip is filled by Tuesday evening. Day 3–5: Plumbing rough-in (waste relocations, hot/cold pipe runs, isolation valves), electrical rough-in (exhaust fan, GPO, shaver point), any required carpentry. This is the noisy, dusty week — you'll need an alternate bathroom.
Week 2: Substrate, waterproofing, tile
Day 6: New cement board or villaboard substrate goes in (depending on your tile substrate spec). Day 7–8: Waterproofing membrane applied by a licensed waterproofer. AS3740-compliant membrane is the bit that quietly determines whether your bathroom leaks in five years. Day 9–10: Membrane cure. Yes, two full days, and you cannot rush this. Day 11–13: Tile installation, walls then floor. Day 14: Grout and silicone.
Week 3: Fit-off and finals
Day 15–16: Plumbing fit-off (toilet, vanity, shower mixer, taps). Day 17: Electrical fit-off (exhaust fan, GPO covers, lighting). Day 18: Shower screen install (these come from glaziers with a 7–10 day lead time, which is why we order them in week 1). Day 19: Clean and final inspection. Day 20: Handover.
Why it sometimes takes longer
Things that legitimately extend the timeline:
- Subfloor problems in Victorian and Edwardian homes — rotten joists discovered during demo. Adds 3–5 days.
- Custom tile selections with long lead times. European porcelain can take 6–8 weeks to land in Australia.
- Strata approval in apartments — committee meetings happen monthly; expect 4–6 weeks of paperwork before work starts.
- Weather, ironically — Melbourne wet winters slow waterproofing cure. Brisbane summer humidity also slows things.
- Variations — you decide mid-job to change the shower hob to level-entry. Add a week.
Things that don't actually extend it
A few common assumptions that aren't true:
- The tile pattern doesn't usually add days. Herringbone and chevron add cost, not much time, unless the room is very large.
- Premium fixtures don't slow it down. A Caroma toilet and a Phoenix toilet install in the same hours.
- The size of the bathroom barely matters below ~10m². A 4m² and an 8m² bathroom take similar time — the fixed steps (waterproofing cure, fit-off) dominate.
How we book around it
When you accept a Quotefor.au bathroom quote, we book the tradie's calendar in two-week or four-week blocks (refresh vs rebuild). We hold the dates against your acceptance. The tradie commits to start date and completion date as part of the quote — variations only apply if you change scope, never for things that should have been spotted at quote time.
