Quoting Software for Waterproofers.

Bathroom and balcony waterproofing in Australia typically costs $40-$85 per m², with most standard bathrooms (6-10m²) landing between $900 and $1,800 once labour, membrane and materials are included. (source: Trusted Tradie Network's 2026 waterproofing cost guide).

The real challenge for waterproofers isn't the maths, it's the detail: waterproofing is almost always priced as part of a bigger bathroom or balcony job, so it needs to sit as its own clean line item rather than getting absorbed into someone else's number. That's the kind of trade-specific logic Scopeflow already gives its seven supported trades, and it's what waterproofers would need before we'd call the trade supported.
