Renovating a bathroom is one of the most impactful home improvement projects you can undertake. Beyond the daily enjoyment of a refreshed space, a well-executed renovation significantly boosts your property's market value. However, for many Australian homeowners, the primary hurdle isn't the design—it's the budget.
At Tilemall, we believe that a successful renovation starts with transparency. This guide breaks down the current costs in the Australian market, helping you plan a project that balances style, functionality, and financial reality.
The Big Picture: Why Costs Vary
If you ask a builder how much a bathroom costs, the answer is almost always, "It depends." While that might feel frustrating, it is the truth. A small ensuite and a large family bathroom might look similar on paper, but the choices made within those four walls can lead to vastly different price tags.
The cost of your renovation is generally shaped by three main pillars: the size of the room, the complexity of the work, and the quality of the finishes. A simple update where the plumbing stays in the same place will always be more affordable than a complete redesign that involves moving the toilet or shower. Similarly, choosing a standard ceramic tile versus a hand-cut natural stone will shift the budget significantly.
The Three Types of Renovation
To help you plan, it is useful to categorise renovations into three broad levels. These figures are based on current Australian market averages for 2025 and 2026 (Hipages).
1. The Cosmetic Refresh (Budget: $8,000 – $15,000)
This option is for homeowners who are comfortable with the current layout but want to update the appearance. It usually focuses on replacing visible items rather than rebuilding the space, such as installing a new vanity, updating tapware, or refreshing finishes.
However, this approach is not generally recommended. During removal or surface updates, existing tiles and waterproofing layers can easily be damaged. Once the waterproofing is compromised, the repair cost can quickly exceed the initial savings, making the renovation less cost effective overall.
Best for: Short term rental preparation or a quick visual update before selling.
Key consideration: The risk of hidden damage to tiles and waterproofing may lead to additional unexpected costs.
2. The Standard Renovation (Budget: $15,000 – $20,000)
This is the most common type of renovation. It involves stripping the room back to the bare studs, re-waterproofing, and installing all new fixtures and tiles. While the layout usually stays the same to save on plumbing costs, everything you see and touch is brand new.
Best for: Family homes where durability and modern style are priorities.
Key feature: High-quality mid-range materials and professional installation.
3. The Luxury Transformation (Budget: $35,000 – $60,000+)
This budget allows for complete creative freedom. You are likely looking at structural changes, such as moving walls to expand the space or relocating the plumbing to create a more functional layout. This budget allows for premium materials like natural stone, custom-made vanities, underfloor heating, and high-end designer tapware.
Best for: "Forever homes" where luxury and personal expression are the goals.
Key feature: Bespoke design and premium finishes.
Breaking Down the Costs: Where Does the Money Go?
It is easy to think that most of your money goes on the nice-looking tiles and the new bath. But actually, a lot of the cost is for the essential work that gets hidden behind the walls once the job is done.
Materials and Fixtures
This is the part of the budget where you have the most direct control. At Tilemall, we see how these choices influence the final price.
Tiles: Tiles are what everyone sees first. Ceramic tiles are cheap and simple to lay. Porcelain is tougher and lasts longer. Natural stone looks amazing but costs more to buy and needs a specialist tiler to install it properly.
Vanities: A standard off-the-shelf vanity is an effective way to save money, usually costing between $500 and $2,000. A custom-built unit designed to fit an awkward corner or specific space will cost significantly more.
Tapware and Showers: We always tell people to spend a bit more on quality here. Taps and shower heads get used every single day, so it is worth choosing reliable brands with good warranties. Trying to save money on cheap taps can cause real problems later on.
The Importance of Waterproofing
Waterproofing is the most critical part of any bathroom renovation. In Australia, there are strict building standards that must be followed. This process involves applying a waterproof membrane to the floors and walls to prevent water from leaking into the house structure.
If waterproofing is not done correctly, it can lead to serious issues like mould, rotted timber, or structural damage. Fixing a leak often requires the entire bathroom to be stripped and rebuilt. Professional waterproofing is an essential investment that protects your home from expensive future repairs.
Decisions That Impact the Price
Small decisions during the planning phase can have a significant effect on the final invoice. For example, keeping the toilet in its original position avoids complex plumbing work. Moving a waste pipe through a concrete floor is a difficult task that increases labour costs.
Tile selection also matters. Large-format tiles create a seamless look, but the floor and walls must be perfectly flat, which takes more time to prepare. Very small tiles, such as mosaics, take much longer to lay and grout. Choosing a standard-sized tile is often the most practical and cost-effective option.
Hidden Costs to Consider
Renovations often involve unexpected expenses, particularly in older homes. Once the old tiles are removed, the builder may find water damage in the wall studs or electrical wiring that does not meet modern safety standards.
We recommend maintaining a "contingency fund" of approximately 10% to 15% of your total budget. If these funds are not needed for repairs, they can be used for final styling or accessories. Having this buffer prevents the project from being delayed by unforeseen issues.
How to Save Without Sacrificing Style
You don't need a massive budget to create a beautiful bathroom. It is all about where you choose to spend and where you choose to save.
1. The "Feature Wall" Strategy: Instead of using an expensive handmade tile for the whole room, use it only on one wall, perhaps behind the vanity or in the shower niche. Use a simpler, more affordable tile for the rest of the space.
2. Keep the Footprint: As mentioned before, avoiding layout changes is the single best way to keep costs down.
3. Update the Lighting: Good lighting can make even a modest bathroom look like a luxury spa. Investing in a well-placed LED mirror or some soft accent lighting offers a high visual return for a relatively low cost.
