Bathrooms might be one of the smallest rooms in the house, but when it comes to renovating, they often pack the biggest punch to your budget. With plumbing, waterproofing, tiling, cabinetry, and lighting all working together in a confined space, the details matter, and so does the planning.
The cost of a bathroom renovation isn’t one-size-fits-all. It comes down to how much structural work is involved, the level of customisation required, and the calibre of fixtures, fittings, and finishes you choose.
Understanding the main cost drivers upfront can help you make smarter decisions, prioritise what matters, and get the most out of your renovation spend.
Key Factors That Influence Bathroom Renovation Costs
Bathroom renovation costs can vary significantly, even between homes of a similar size. The overall price depends not just on how big your bathroom is, but also the decisions you make around design, functionality, and finishes. It’s these key factors that shape how much you’ll spend on your project.
Size & Layout – A larger bathroom or one that requires major layout changes, like shifting the toilet or shower, will naturally cost more to renovate.
Plumbing & Electrical Works – Upgrading old plumbing or wiring, or adding new fixtures like lighting, power points, or heated towel rails, can significantly increase labour and compliance costs.
Tiling & Waterproofing – The amount and type of tiling you choose, along with the waterproofing requirements, can make up a major portion of your renovation budget.
Vanity, Fixtures & Fittings – Choosing designer tapware, a custom vanity, or a wall-hung toilet will elevate your finish but also raise the total cost.
Materials & Finishes – Higher end materials such as stone, brushed metal, or timber veneer will increase costs compared to standard alternatives.
Access & Site Conditions – Limited access, older home structures, or tricky site conditions can add time, complexity, and expense to the build.
Average Bathroom Renovation Costs In Australia
When planning your bathroom renovation, having a clear understanding of potential cost tiers can help you budget more confidently and avoid unexpected surprises. At Novalé, we’ve developed four distinct pricing levels, Standard, Upgraded, Premium, and Bespoke, to guide you through what to expect depending on your choices. These tiers reflect a range of factors including layout changes, tiling heights, tile selections, and PC items such as fixtures and fittings.
Please note: These estimates apply to complete renovations only (not cosmetic makeovers) and do not include GST. Each tier offers increasing levels of complexity, finishes, and customisation to suit your style, needs, and investment level.
Standard Bathroom Renovation
Cost: $23,000 – $31,000 (excl. GST)
Ideal for homeowners who want a clean, refreshed space without major structural changes, this tier focuses on functionality and timeless style. A standard bathroom renovation typically includes cost-effective tile selections, entry-level fixtures, framed shower screens, and minimal changes to the existing layout. It’s perfect if you’re after a complete bathroom transformation that fits within a tighter budget, without compromising on quality workmanship.
Upgraded Bathroom Renovation
Cost: $27,000 – $39,000 (excl. GST)
This level is for those wanting to elevate their space with more refined selections and added flexibility. Expect features like semi-frameless shower screens, wall-hung vanities, engineered stone benchtops, and upgraded PC items. Minor layout changes, such as repositioning the vanity or toilet, can be included, offering a more tailored and modern finish while keeping within a reasonable price range.
Premium Bathroom Renovation
Cost: $36,000 – $47,000 (excl. GST)
Designed for clients seeking a luxurious, high-end finish, this tier introduces features like full-height tiling, custom joinery, underfloor heating, and premium fixtures and fittings. It often includes layout modifications and design-led details that make a statement. A premium bathroom doesn’t just meet your functional needs, it enhances your lifestyle with a sleek, cohesive design and elevated material choices.
Bespoke Bathroom Renovation
Cost: $47,000 onwards (excl. GST)
A bespoke bathroom is a fully tailored space, designed down to the smallest detail. This tier is ideal for those who want a one-of-a-kind result with integrated lighting, designer fittings, natural stone, custom mirrors, and architectural details throughout. Whether you’re after a spa-like retreat or a striking, design-forward showpiece, this level offers unlimited creative freedom with expert craftsmanship to match.
Example Breakdown – ‘Upgraded’ Bathroom Renovation

To help guide your expectations, here’s a cost breakdown example for an ‘Upgraded’ Bathroom Renovation, similar in scope to our Mount Colah project. This represents a typical 6m² bathroom in a house with upgraded selections and a standard structural scope. Please note, this is a general pricing guide only, and actual costs may vary based on individual site conditions, selections, and build requirements.
Labour & Building Materials
Cost: $22,000 – $29,000 + GST approx.
This includes demolition, waterproofing, construction, tiling, and all building works required to deliver a complete bathroom. Costs in this range are impacted by factors such as tiling height, room size, access, asbestos removal (if needed), and the structure of the home (e.g. brick vs timber frame). Most bathrooms in this category have no layout changes or wall/door removals and often feature full-height tiling.
Tiles, Fixtures & Fittings
Cost: $5,000 – $10,000 + GST approx.
This includes all visible selections, such as porcelain tiles, matte black tapware, a freestanding acrylic bath, twin rail shower, and a custom (off-the-shelf) vanity with a stone benchtop. Variations in tile sizing, finish levels, and brand upgrades can shift your total depending on the look and feel you’re after.

Total Project Cost Estimate
Cost: $27,000 – $39,000 + GST approx.
Note: Estimates are shown as ranges as there are factors that affect costs: dwelling type & age, street access etc. For example, a 30 year old standalone timber framed single storey house in a quiet street with good access will be lower in the cost range compared to a 75 year old 3rd storey brick apartment in a busy street.
