What affects the price?
Bathroom size
A small ensuite (3–4m²) costs less than a main bathroom (5–7m²) or large family bathroom. Size affects tiling, waterproofing, and labour time most significantly.
Fixture and fitting quality
Builder-grade fixtures start around $2,000–$4,000 for a full suite. Mid-range (Caroma, Fowler) runs $4,000–$8,000. Designer (Parisi, Reece) suites cost $8,000–$20,000+.
Tiling
Tiling is the biggest labour cost. Floor-to-ceiling tiles in a standard bathroom add $3,000–$7,000 in labour and materials. Budget tiles cost $30–$60/m²; designer tiles cost $100–$300/m².
Waterproofing
Australian building regulations require waterproofing in all wet areas. This adds $800–$2,000 to the job but is non-negotiable. It must be done by a licensed waterproofer.
Plumbing relocations
Keeping fixtures in the same position is cheapest. Moving the toilet, shower, or vanity requires re-routing waste pipes, which can add $2,000–$5,000 to the budget.
Typical cost breakdown
Estimates are based on Australian average rates in 2025. Prices in Sydney and Melbourne are typically 10–20% higher than other capital cities.
Frequently asked questions
How long does a bathroom renovation take?
A full renovation of a standard bathroom typically takes 2–4 weeks from strip-out to completion. Larger or more complex bathrooms can take 4–6 weeks. The main delays are tiling (waiting for adhesive to cure) and fixture lead times.
Do I need council approval for a bathroom renovation?
Generally no, as long as you're not moving walls or changing the footprint of the bathroom. However, plumbing and electrical work must be performed by licensed tradespeople who certify the work.
How much value does a new bathroom add to my home?
A quality bathroom renovation typically returns 70–80% of its cost in added property value. In competitive markets, an updated bathroom can make the difference between a quick sale and sitting on the market.
What is a wet room and how much does it cost?
A wet room is a fully waterproofed, open shower bathroom with no shower base or screen. They're popular in high-end renovations and cost $5,000–$10,000 more than a standard bathroom due to full waterproofing and floor drainage requirements.
Should I stay at home during a bathroom renovation?
Yes in most cases, though you'll be without the bathroom for 2–4 weeks. Most renovators plan around using another bathroom or make arrangements. Your tradesperson will advise on the timeline for each stage.
