How Much Does a Bathroom Renovation Cost in Perth? A 2026 Guide

If you're thinking about renovating your bathroom, one of the first questions you're probably asking is:

"How much does a bathroom renovation cost in Perth?"

The honest answer is that there isn't one fixed price. The cost depends on the size of your bathroom, the existing condition, the layout, the materials and fixtures you choose, and how much work is required.

As a general guide, Perth bathroom renovations in 2026 can range from around $10,000 for a basic renovation to $40,000 or more for a higher-end renovation. More extensive or luxury renovations can cost considerably more. Current Perth cost guides show similar ranges, although individual projects can vary significantly.

At Westline Bathroom, we believe homeowners should understand where their money is going before starting a renovation. This guide explains the main costs involved and what can make your bathroom renovation more or less expensive.

Typical Bathroom Renovation Costs in Perth

As a broad 2026 guide, you might expect:

Renovation typeApproximate Perth costBasic renovation$10,000 – $18,000Standard / mid-range renovation$18,000 – $35,000Premium renovation$35,000 – $50,000+Luxury / high-end renovation$50,000+

These figures are indicative only. Your actual cost will depend on the scope of work, materials, fixtures, labour and condition of the existing bathroom. Some current Perth guides report lower starting points, while others place standard full renovations higher, which shows why obtaining a detailed project-specific quote is important.

What Is Included in a Bathroom Renovation?

A complete bathroom renovation can involve much more than replacing the vanity and tiles.

Depending on your project, the work may include:

• Removing the existing bathroom

• Demolition and waste removal

• Plumbing work

• Electrical work

• Wall and floor preparation

• Waterproofing

• Wall and floor tiling

• Vanity installation

• Toilet installation

• Shower installation

• Shower screen

• Bath installation

• Tapware

• Mirrors

• Lighting

• Ventilation

• Painting and finishing

The more elements you change, the greater the overall cost is likely to be.

1. Bathroom Size

The size of your bathroom is one of the obvious factors affecting cost.

A small ensuite generally requires fewer tiles and materials than a large family bathroom. However, even a small bathroom still requires many of the same specialist trades and processes, such as plumbing, electrical work, waterproofing and tiling.

This means that making a bathroom smaller doesn't necessarily reduce the renovation cost proportionally.

2. Changing the Bathroom Layout

One of the biggest ways to increase the cost of a renovation is changing the existing layout.

For example, keeping the toilet, shower and vanity in approximately the same locations can reduce the amount of plumbing work required.

Moving plumbing points can involve additional labour and, depending on the property, access to the existing plumbing may be difficult.

If you're working with an older Perth home, it is particularly important to inspect the existing bathroom before deciding on a new layout.

Keeping the existing layout where practical can be one way to control your renovation budget.

3. Waterproofing

Waterproofing is an essential part of a bathroom renovation.

Although waterproofing is hidden behind the tiles, it is one of the most important parts of the bathroom.

Poor preparation or waterproofing can lead to serious moisture problems, so it should not be treated as an area where you simply choose the cheapest option.

When comparing renovation quotes, make sure you understand what waterproofing work is included and what documentation or certification will be provided.

4. Bathroom Tiling

Tiles can make a significant difference to both the appearance and cost of your bathroom.

The price can vary depending on:

• Tile material

• Tile size

• Tile pattern

• Number of tiles

• Wall height

• Floor area

• Feature tiles

• Cutting requirements

• Grout and finishing

• Labour

For example, a simple standard tile installation will generally involve less labour than a bathroom using large-format tiles, intricate patterns, niches, feature walls or detailed tile cuts.

A good tiling result starts with good preparation. Walls and floors need to be suitable for the selected tiles before installation begins.

5. Bathroom Fixtures and Fittings

The products you choose can have a major effect on the final cost.

Your bathroom may include:

• Vanity

• Basin

• Toilet

• Shower

• Shower screen

• Bath

• Tapware

• Mirror

• Heated towel rail

• Accessories

There are products available at many different price points, so you can often design a bathroom around your budget.

The important thing is to consider the quality, suitability and long-term maintenance of the products rather than choosing everything based purely on appearance.

6. The Condition of Your Existing Bathroom

An older bathroom can contain problems that aren't obvious before demolition.

For example, once the existing tiles, wall linings or fixtures are removed, you may discover:

• Damaged wall framing

• Deteriorated flooring

• Plumbing problems

• Previous waterproofing issues

• Moisture damage

• Uneven surfaces

• Rust or corrosion

• Other hidden building issues

These issues can increase the cost of the renovation.

For this reason, it is wise to keep some allowance in your budget for unexpected work.

7. Premium Materials and Design Features

If you want a high-end bathroom, your choice of materials and design features can significantly increase the budget.

Examples include:

• Large-format or feature tiles

• Custom vanities

• Stone surfaces

• Frameless shower screens

• Freestanding baths

• Feature lighting

• Recessed shower niches

• Heated flooring

• Designer tapware

• Custom cabinetry

These features can create an impressive result, but they also require additional materials, labour or specialist installation.

How Can You Keep Your Bathroom Renovation Costs Under Control?

You don't necessarily need to choose the cheapest products to keep your renovation within budget.

Instead, consider where your money will make the biggest difference.

Keep the existing layout where possible

Avoiding unnecessary plumbing relocation can reduce additional labour and construction costs.

Choose tiles carefully

You can create a high-quality appearance without using expensive tiles throughout the entire bathroom.

Spend money on the important areas

Waterproofing, preparation and workmanship are areas where quality matters.

Choose fixtures before finalising your budget

Knowing the approximate cost of your vanity, toilet, shower, tapware and other fixtures can help prevent surprises later.

Get an itemised quote

Don't compare renovation quotes based only on the final dollar amount.

Check what each quote actually includes.

For example, one quote may include demolition, waterproofing, tiling and waste removal, while another may exclude some of these items.

An itemised quote makes it easier to understand what you are paying for.

How Long Does a Bathroom Renovation Take?

The timeframe depends on the size and complexity of the renovation.

A straightforward renovation may take a few weeks, while a larger renovation involving layout changes, structural work or custom products can take longer.

Delays can also occur because of product availability, unexpected issues discovered during demolition or coordination between different trades.

It's a good idea to discuss the expected timeframe before work begins.

Is a Bathroom Renovation Worth the Investment?

A bathroom renovation can improve more than just the appearance of your home.

A well-designed bathroom can provide:

• Better functionality

• Improved storage

• Easier cleaning

• A more comfortable space

• Updated fixtures and finishes

• Improved use of available space

If you're renovating before selling your property, it is also worth considering the overall value of the renovation and avoiding unnecessary overcapitalisation.
