How much does a bathroom renovation cost?

How much to renovate a bathroom? In Australia, the cost of bathroom renovation can range from $8,000 to $40,000 or more, depending on the scope of the work and the size of your bathroom.

Bathroom renovation cost by size:

• Small bathroom renovation: $20,000 to $27,000
• Large bathroom with quality renovations: $25,000 to $40,000
• Premium bathroom renovation: $40,000 or higher

Here’s a detailed breakdown of bathroom renovation costs based on budget, standard, and luxury options:

If you’re on a tight budget, a complete overhaul of your bathroom may not be feasible, but with some careful planning, you can still revamp the space without breaking the bank. A budget-friendly renovation typically focuses on superficial changes, such as updating fixtures, painting, or replacing existing tiles, without requiring extensive plumbing work like new shower, bath, or toilet installations.

For renovations closer to $15,000, you may be able to add new installations like a shower, but expect some compromises. For example, you might have to choose a basic framed shower screen, a standard, affordable toilet, and a simple vanity. Opting for large porcelain tiles can also help keep costs down while still improving the overall look.

Standard Bathroom Renovation Cost: $15,000 – $40,000

For most homeowners, a standard bathroom renovation falls within this range. It allows for a wider selection of materials and fittings, such as higher-quality tapware, stylish bathroom tiles, frameless shower screens, a more attractive bathroom vanity, or even a freestanding bathtub. If you don’t require extensive plumbing or electrical work, this budget will provide a significant upgrade to the overall look and feel of your bathroom.

Premium or Luxury Bathroom Renovation Cost: $40,000+

A premium or luxury bathroom renovation gives you the freedom to completely redesign your space and make significant changes to the layout, including relocating plumbing and upgrading electrical work. With a larger budget, you can opt for high-end features such as freestanding bathtubs, heated towel rails, wall-hung vanities and toilets, premium tiles, custom wall tiling, floor heating, and a range of luxury bathroom accessories. This budget allows you to create a spa-like retreat with top-tier materials and finishes.

What factors influence bathroom renovation cost in Australia?

Several factors can impact the cost of a bathroom renovation in Australia, ranging from the size of the space to the quality of materials used. Here’s a breakdown of key considerations:

1. Size of your bathroom: Larger bathrooms typically require more materials and labour, which increases the overall cost.
2. Timeframe: The longer the project takes, the higher the labour costs. Delays or complex renovations can extend the timeline.
3. Fittings, materials, and labour: The choice of materials and the quality of fixtures (e.g., tiles, tapware, and vanities) can significantly affect the total cost. Additionally, skilled labour rates can vary based on your location and the complexity of the work.
4. Structural work: If the renovation involves structural changes, such as adding a window or skylight, or relocating walls, this will increase costs.
5. Plumbing and fixture relocation: Moving plumbing and fixtures like toilets, baths, or showers is a costly part of a renovation, especially if major plumbing work is required.
6. Complete bathroom overhaul: If you’re installing an entirely new bathroom, this will involve additional costs for new plumbing, fixtures, and possibly flooring and wall preparation.
7. Electrical work: Updating lighting, installing new power outlets, or upgrading the electrical system requires professional electricians and can add to the overall budget.
8. Cost of tiling and fittings: The choice between budget or luxury tiles, sinks, bathtubs, shower screens, and other fittings will have a large impact on the cost.
9. Building permits: Some renovations, especially those involving structural work or plumbing changes, may require a building permit, adding extra costs for application fees and approval processes.
10. Unexpected issues: Hidden issues like mould, water damage, or asbestos can increase costs unexpectedly as they require additional remediation work.
11. Quality vs. budget options: Costs for bathroom accessories, such as shower screens, exhaust fans, lighting, towel rails, and waterproofing, can vary greatly. Shopping around for quality yet budget-friendly options can help keep costs under control.

By carefully considering these factors and prioritising your needs, you can better estimate and manage your bathroom renovation costs.

Step-by-step guide to bathroom renovation

Before starting your bathroom renovation, it’s crucial to do thorough research, create a clear plan, and hire the right tradespeople. Knowing the timeline and who you need will help the process run smoothly.

Here’s a step-by-step guide to understanding the typical bathroom renovation process:

1. Speak to Your Local Council

• Why: Depending on the scope of your renovation and your location, you may need council approval before starting.
• What to Do: Check with your local council for any regulations or permits required. This is especially important for structural work or significant plumbing changes.

2. Design Your New Bathroom Look

• Why: Having a clear vision will help ensure everything is in the right place and the renovation meets your needs.
• What to Do: Plan the layout of your bathroom, including the positions of the shower, toilet, bathtub, and vanity. You can design it yourself using an app or paper, or consult an architect or bathroom builder for larger projects.

3. Choose Your Fittings

• Why: Deciding on your fittings early helps avoid delays and ensures your tradespeople know what they’re working with.
• What to Do: Purchase your bathroom products in advance—whether it’s tiles, a bathtub, a vanity, or tapware. This will help your tradesmen stay on schedule and prevent waiting for out-of-stock products.

4. Demolish the Old Bathroom

• Why: Clearing out the old bathroom is the first major step in the renovation process.
• What to Do: Your tradespeople will remove the existing tiles, fixtures, and fittings to prepare for the new installations.

5. Plumbing and Electrical Rough-In

• Why: This is a crucial step to prepare the bathroom for new fixtures and appliances.
• What to Do: Plumbers will adjust the plumbing system for the new layout and install pipes for your new fixtures. Electricians will run the necessary wiring for lighting, exhaust fans, and other electrical components.

6. Rendering the Walls

• Why: This step ensures the walls are smooth and properly prepared for tiling and waterproofing.
• What to Do: Your walls will be rendered to create a suitable surface for the new tiles and waterproofing layer.

7. Waterproofing, Tiling, and Painting

• Why: Waterproofing is essential to protect your bathroom from moisture damage, while tiling and painting will give it a fresh look.
• What to Do:
  • Allow up to 5 days for the waterproofing to cure.
  • After curing, tiling can begin.
  • Once tiling is complete, painting can be done to finish off the space.

8. Fit-Out with Fixtures and Finishing

• Why: This is when your bathroom begins to take shape with the installation of all key elements.
• What to Do:
  • Plumber: Installs the toilet, shower screen, bathtub, basin, tapware, and vanity.
  • Electrician: Installs the lighting, exhaust fan, and any other electrical components.
  • Final touches, such as towel rails and mirrors, will also be added.

By following these steps and staying organised, your bathroom renovation will run more smoothly and efficiently, resulting in a beautifully updated space.

Who do I hire for a bathroom renovation?

For a bathroom renovation, you’ll need to hire a variety of professional tradespeople, especially if you’re doing a complete overhaul. Bathroom renovators or builders are often used as they are already equipped with a list of necessary tradies to get the job done efficiently. This will certainly eliminate some of the stress involved with hiring multiple tradesmen.

Otherwise, for a typical bathroom project you’ll likely require the following services:

• Plumbers
• Electricians
• Handyman
• Carpenters and cabinet makers
• Tilers and waterproofers (many tilers are licensed to install waterproofing)

For large renovations and bathroom remodels, you might need an architect for your plans.

It’s essential to verify that your bathroom renovators and tradespeople have the necessary licenses and insurance to work on your property. Always do your research. Get multiple quotes and request to see examples of their previous work, along with references, to ensure you’re hiring qualified professionals.
