How Much Does a Bathroom Renovation Cost? Understand Before You Renovate

Bathroom renovations are one of the most asked-about projects in Brisbane. Everyone wants to know the same thing: what is the cost for a bathroom renovation?

The truth is, there’s no single answer. Prices vary depending on the type of renovation, the complexity of the work, and the choices you make along the way. We’ve mapped out the main cost considerations so you can approach your renovation prepared.

What Is the Average Cost for a Bathroom Renovation in Brisbane?

Bathroom renovation costs are one of the first things Brisbane homeowners want to understand before starting a project. Knowing the national averages alongside local pricing trends gives a clearer picture of what to budget for.

National vs Brisbane-Specific Pricing Trends

Across Australia, bathroom renovation costs are steadily rising. Brisbane sits close to the national average, but local labour rates and supply availability mean your budget might stretch differently here compared to Sydney or Melbourne.

Why Do Costs Vary So Widely?

No two bathrooms are alike. The size of your bathroom, the finishes you choose, and the extent of changes all shape the final price. Labour usually takes the biggest share of the budget, with materials close behind. A light refresh keeps costs in check, but a full redesign can drive the budget up fast.   

Bathroom Renovation Cost by Renovation Type

Not all bathroom renovations are created equal. The scope of work determines both the price and the overall impact on your home. 

Cosmetic or Surface-Level Updates

These projects focus on simple updates such as fresh paint, new fixtures, or re-grouting. They are cost-effective and give your bathroom a fresh look without major work.

Standard Full Renovation

A full renovation typically involves stripping out the old bathroom, updating plumbing, tiling, and installing modern fittings. This option is practical, stylish, and popular in Brisbane homes.

Luxury or Custom Bathrooms

High-end projects feature designer fittings, bespoke cabinetry, and premium finishes. They transform the space into a personal retreat, but naturally come with higher costs.

What Drives Up the Cost for a Bathroom Renovation?

Certain factors can quickly increase the price of a bathroom renovation. Understanding these helps you plan realistically and avoid surprise costs.

Plumbing and Electrical Changes

Moving pipes or rewiring for new lighting adds time and specialist labour. Keeping the same layout usually keeps costs lower.

Waterproofing and Tiling Complexity

Waterproofing must meet strict Australian standards and will increase the project cost. Detailed patterns or large-format tiles also require more skill and time to install.

Structural Changes or Layout Redesigns

Knocking out walls or changing the floor plan makes projects more complex. These changes often need engineering input and extra approvals.

Hazardous Material Removal (e.g. Asbestos)

Older bathrooms often contain asbestos materials. By law, only licensed professionals can remove them safely, which may extend your renovation timeframe and add to the overall cost.

Key Budget Categories to Consider

How much does a bathroom renovation cost? The answer depends on how your budget is divided across labour, materials, fittings, management, and approvals.

Labour vs Material

Labour often takes the biggest share of the budget, sometimes more than half. Materials such as tiles, paint, and cabinetry cover the remaining budget and can differ greatly in price.

Fixtures and Fittings

Toilets, vanities, shower screens, and lighting all fall into this category. Entry-level products keep costs low, while designer brands can quickly push the budget higher.

Project Management or Builder’s Margin

Builders charge a margin to manage trades, scheduling, and compliance on your behalf. This cost ensures the project runs smoothly and avoids unnecessary delays.

Council Approvals

Cosmetic or like-for-like bathroom upgrades usually don’t need approval. However, new builds, extensions and new or additional bathrooms work generally require council assessment as they affect plumbing, drainage, and your home’s integrity.

How to Keep Your Bathroom Renovation on Budget

Bathroom renovation costs can quickly rise if you don’t plan. Clear priorities and the right support make all the difference.

Smart Planning and Prioritisation

Decide early what matters most, whether it’s storage, layout, or finishes. Having clear goals keeps you from overspending on extras you don’t really need.

Working With a Transparent Builder

Detailed, itemised quotes show you exactly where your money is going. This level of clarity prevents hidden costs and builds trust during the project.

Where to Splurge vs Save

Invest in waterproofing and quality fixtures you use every day. Save on decorative touches or features that can be upgraded later.
