Bathroom waterproofing in Melbourne typically costs $1,000-$2,000 for a small bathroom, $2,000-$4,000 for a medium bathroom, and $4,000-$6,000+ for large or complex projects.

Yes. In Victoria, waterproofing for wet areas must comply with AS 3740 and the National Construction Code. Under the Building Act 1993 and the Domestic Building Contracts Act 1995, waterproofing work must be carried out by practitioners registered with the Victorian Building Authority (VBA). Before you book, check the contractor's registration on the VBA register and ask for a certificate of currency for their insurance. Request your free quotes to get a free quote from a local professional.

A standard bathroom waterproofing job takes 2-3 days including surface preparation, membrane application, curing time, and flood testing. Complex remedial work may take longer. The contractor you speak with can give you an accurate timeline in their quote.

AS 3740 is the Australian Standard for waterproofing of domestic wet areas. It specifies minimum membrane requirements, bond-breaker placement, and testing protocols. Non-compliant waterproofing can void insurance and create costly structural problems. Ask your contractor to confirm in writing that their work meets AS 3740.

Common signs include water stains on ceilings below wet areas, musty odours, peeling paint, loose tiles, and visible mould. If you notice any of these, request a free inspection through our service — early detection saves thousands in repair costs.
