Guide to Bathroom Renovation or Remodelling in Victoria
Renovating a bathroom in Victoria can improve comfort, function and long-term value. Victorian regulations and safety rules can be detailed, but understanding the basics helps you avoid delays and costly mistakes.
When Do You Need a Building Permit in Victoria?
A building permit may be required for:
- Moving, altering or removing loadbearing walls
- Installing, altering or removing windows
- Extensions outside the existing building footprint
- Installing heavy fixtures that need structural reinforcement
A building permit is not required for:
- Replacing tiles or fixtures
- Painting or updating cabinetry

- Installing towel racks or other non-structural items
Even when a permit is not required, all bathroom work must still comply with:
- The National Construction Code

Tip:
The bathroom is one of the most highly regulated rooms in a home. Waterproofing, ventilation, glazing and even door hardware must meet strict standards.
Why You Should Always Use Licensed Trades
Plumbing and electrical work must be completed by qualified and licensed trades. This applies even if a permit is not needed. Proper certification protects you during insurance claims, future property sales or future renovations.
Keep copies of waterproofing certificates, plumbing compliance certificates and electrical safety certificates. These documents can save significant time and cost later.
