Budget Tiers Explained
- Cosmetic ($12k–$18k): Retain layout, swap fixtures, basic tile refresh.
- Standard ($22k–$32k): Full strip-out, new waterproofing, mid-tier tiles.
- Premium ($35k–$55k+): Large format tiles, in-wall cisterns, custom vanities, underfloor heating.
Major Cost Drivers
Premium fixtures (freestanding baths, brushed brass tapware, stone resin basins), complex niches, full-height tiling, and moving drains increase spend.
Waterproofing & Compliance
AS3740 waterproofing compliance is non-negotiable. Always request a certificate. Expect $650–$1,200 depending on size and complexity.
Tiling Labour & Materials
Full-height tiling increases labour significantly, especially for rectified porcelain or natural stone.
- Labour: $95–$140/m² (standard porcelain)
- Large format (750mm+): +20–30%
- Feature walls / mosaics: Premium labour
Plumbing & Fixtures
Quality mixers, thermostatic showers, recessed drains and custom vanities drive luxury feel. Always compare WELS ratings for water efficiency.
Reducing Unnecessary Spend
Avoid overspend by limiting niche count, choosing one hero feature (e.g. stone vanity), and selecting durable mid-range porcelain over exotic marble.
Key Takeaways
- Waterproofing certificates essential
