How to Renovate Your Bathroom in Australia

Renovating your bathroom is one of the smartest upgrades you can make to your home. A well-planned bathroom renovation can increase your property’s value, improve functionality, and give you the designer finish you’ve always wanted. But in Australia, there are specific codes, costs, and processes you need to understand before you start.

Here’s a complete guide to doing it right.

Step 1: Know the Rules and Codes

In Australia, bathroom renovations must comply with the National Construction Code (NCC) and relevant Australian Standards. These cover waterproofing, ventilation, plumbing, and electrical safety. For example:

• All wet areas must be waterproofed by a licensed professional.

• Electrical work must be done by a qualified electrician.

• Plumbing alterations require a licensed plumber.

Skipping compliance may not only risk fines but also void insurance.

Step 2: Plan Your Budget

Bathroom renovations in Australia can cost anywhere from $10,000 to $40,000+ depending on the scope. A simple refresh (new fittings and paint) will be on the lower end, while a full structural redesign (moving plumbing, high-end finishes) sits on the higher end. Always set aside an extra 10–15% for unexpected costs.

Step 3: Design and Layout

The biggest mistake homeowners make is starting without a clear design. A strong design should consider:

• Layout efficiency – keep plumbing in the same position where possible.

• Space optimisation – floating vanities and frameless showers make smaller bathrooms feel bigger.

• Lighting and ventilation – natural light plus adequate exhaust fans prevent mould growth.

• Style consistency – match tiles, fixtures, and finishes with your overall home style.

Step 4: Choose the Right Trades

Even if you’re a confident DIY renovator, some jobs legally require licensed trades in Australia. Typical renovation team includes:

• Plumber

• Electrician

• Tiler

• Waterproofing specialist

• Cabinet maker or carpenter

Hiring experienced trades saves money in the long run by preventing costly mistakes.

Step 5: Materials and Fixtures

Australian homeowners are spoilt for choice when it comes to bathroom products. Popular picks include:

• Tiles: Porcelain (durable, low maintenance) or natural stone (luxury, but higher upkeep).

• Vanities: Floating for modern style or floor-standing for maximum storage.

• Tapware: Matte black and brushed brass are trending in 2025.

• Showers: Walk-in frameless showers for a sleek look.

Step 6: Timeline and Stages

A standard bathroom renovation in Australia usually takes 3–6 weeks, depending on size and complexity. The stages include:

1. Demolition and removal

2. Plumbing and electrical rough-in

3. Waterproofing and inspection

4. Tiling and flooring

5. Cabinetry and fixtures

6. Final plumbing/electrical fit-off

7. Clean and handover
