Introduction: What Impacts Bathroom Renovation Cost?
If you’re planning to update your bathroom in 2025, one of your first questions will likely be: how much does a bathroom renovation cost? The answer depends on your goals, materials, and who you hire for the job. In Adelaide, bathroom renovations can vary widely — from small cosmetic updates to complete rebuilds.
This guide by South Adelaide Plumbing & Gas breaks down everything you need to know: average prices, what affects the total cost, and how to plan your project using a bathroom renovation checklist.
Understanding Bathroom Renovation Costs in Adelaide
Let’s look at the typical cost range you can expect for different bathroom types:
Key Factors That Affect the Total Cost
1. Bathroom Size
A small ensuite might only need a few fittings and less tiling, while a large family bathroom can double the cost.
2. Plumbing and Drainage
If you’re moving sinks, toilets, or showers, expect to pay more. Plumbing changes are labor-intensive and must meet Australian plumbing codes.
Visit South Australian Government’s Building Guidelines for more details.
3. Materials and Fixtures
Luxury tiles, stone benchtops, or designer tapware will increase costs. Budget options can still look great with smart design.
4. Labor and Trades
Bathroom renovations involve multiple professionals — plumbers, tilers, electricians, and sometimes builders. Licensed experts like South Adelaide Plumbing & Gas ensure safe installations and code compliance.
5. Waterproofing and Ventilation
Waterproofing can add $500–$1,000 but skipping it risks expensive water damage later. Proper ventilation is also essential to prevent mould.
Retiling Bathroom Cost: A Closer Look
Retiling often makes the biggest visual difference. The retiling bathroom cost depends on:
- Tile type: Ceramic is the most affordable, while porcelain and natural stone cost more.
- Tile size: Small tiles take more time to install.
- Labor rates: Expect around $40–$100 per square metre for professional tiling in Adelaide.
- Waterproofing: Add $500–$1,000 if not already included.
If your tiles are dated or cracked, retiling can instantly refresh your space without a full renovation.
The Ultimate Bathroom Renovation Cost in Adelaide Checklist
Before starting, it’s smart to plan everything in order. Here’s a step-by-step bathroom renovation checklist to help guide you:
