Waterproofing is the part of a bathroom renovation most homeowners never see and many renovation companies get wrong. AS 3740 specifies exactly where membranes go, how high, what products are approved, and how long cure times must be between coats. We document waterproofing with photos before tiles go on. If you ever have a leak and need to prove compliance, you’ll have the documentation.

Bathroom Renovation FAQs
AS 3740 is the Australian Standard for waterproofing of domestic wet areas. It specifies membrane placement (minimum 150mm from floor in wet areas, minimum 1,800mm at shower head height), approved products, and required cure times. Mandatory in NSW. We photograph waterproofing before tiling — so you have proof of compliance if you ever need it.
$12,000–$20,000 for a basic refresh. $20,000–$35,000 for a mid-spec renovation with new layout and quality fixtures. $35,000–$45,000+ for luxury with custom joinery and wet room. Full cost guide here.
3–6 weeks. Waterproofing cure time (24–72 hours between coats) determines the first week. Custom vanity joinery takes 4–6 weeks if ordered — so this is specified and ordered before demolition starts.
