How Much Does a Bath Cost in Perth? Supply & Installation Guide
Renovators often ask the same question early in the planning process: how much does a bath cost? The answer can vary more than most people expect. The price of a bath depends on several factors, including the type of bath you choose, the size of the unit and how complex the installation will be.
Over the years, I’ve seen plenty of homeowners budget for the bath itself but overlook installation costs. In reality, the total bath cost in Perth can include more than just the fixture. Plumbing adjustments, replacing an existing bath, or relocating pipes can all influence the final price.
The good news is that many modern baths are far more affordable than people assume. Acrylic baths, for example, offer excellent durability and comfort while remaining very budget-friendly.
In this guide, I’ll break down typical bath prices in Perth, explain the differences between inset, freestanding and back-to-wall baths, and outline realistic bath installation costs. By the end, you’ll have a clear idea of what to expect before starting your bathroom renovation.
How Much Does a Bath Cost in Perth?
Bath prices in Perth vary depending on the type of bath and the complexity of installation. Standard acrylic baths are the most affordable option, while freestanding and stone baths typically cost more due to design and materials.

Typical Installation Cost (Perth)
| Installation Type | Typical Cost |
| Standard bath installation | $250 – $550+ |
However, installation costs can increase depending on the scope of the work. For example:
- relocating plumbing pipes can add $1,000 – $2,000+
- removing an old bathtub may cost $1,000 – $2,500, depending on demolition and disposal
- structural changes or floor reinforcement may increase labour costs
These additional factors mean the total bath installation cost can vary significantly depending on the renovation.
Typical Bath Prices in Perth
Bath prices in Perth vary mainly by bath type and overall design style. While some baths are very affordable, premium materials and larger, statement designs can significantly increase the price.
Here’s a general guide to typical bath prices based on the most common bath types.
- Inset baths: Inset baths are usually the most affordable option and are commonly installed against a wall or built into a tiled hob. Basic acrylic inset baths can start from around $250–$800, making them a popular choice for budget-friendly renovations.
- Freestanding baths: Freestanding baths are often chosen as a statement feature in modern bathrooms. Acrylic freestanding baths typically range from $800–$2,500, depending on the design and size.
- Back-to-wall baths: Back-to-wall baths combine the appearance of a freestanding bath with the practicality of a wall-mounted installation. These baths usually range from $1,500–$2,700, depending on style and size.
- Stone or marble baths: Stone composite and marble baths sit at the premium end of the market. Stone baths often start at around $4,000, while marble bathtubs can range from $5,000 to $10,000 or more.
In most Perth homes, acrylic baths remain the most common choice. They offer a good balance of price, durability and comfort while remaining lightweight and easier to install during a bathroom renovation.
Bath Sizes and How They Affect Price
Bath size is one of the main factors influencing the overall cost of a bath. Larger baths require more materials to manufacture and often need more space within the bathroom layout, which can also affect installation planning.
Common bath sizes include:
- 1300mm baths: These compact baths are designed for smaller bathrooms, ensuites or tight layouts where space is limited.
- 1500mm baths: A popular option for smaller family bathrooms, offering slightly more comfort while still fitting into compact spaces.
- 1600mm baths: Often considered a balanced option, these baths provide extra bathing space without requiring as much room as a full-size unit.
- 1700mm baths: This is the most common full-size bath used in many Australian homes and is typically chosen for standard bathroom layouts.
When planning a renovation, it’s important to consider how bath dimensions fit within the overall bathroom layout. Larger baths will increase the price and may also influence installation requirements if additional space adjustments are needed.
Bath Installation Costs in Perth
The bath installation cost depends largely on whether the new bath replaces an existing unit or requires changes to the bathroom layout. A straightforward replacement, where the new bath connects to the same plumbing position, is usually the most affordable option.
Typical bath installation costs in Perth range from $250 to $550+.
These costs generally apply when installing a bath in the same position as the existing unit and connecting to existing plumbing.
If plumbing needs to be relocated, labour costs can increase significantly because additional pipework and adjustments are required. More complex installations may also involve removing the existing bath, modifying the bathroom layout or adjusting surrounding fixtures.
According to Boda Building Group, straight bath replacements are usually the most cost-effective, while moving plumbing or altering the bathroom layout will increase the overall renovation labour costs.
Additional Costs That Can Affect Bath Installation
While the price of the bath itself is important, several renovation factors can influence the final bath installation cost. These additional considerations often arise during bathroom renovations and can increase the overall project budget.
Common factors that affect installation costs include:
- Plumbing relocation: Moving existing pipes to suit a new bath location can increase labour costs because additional plumbing work is required.
- Waterproofing work: If the bathroom layout changes or surrounding surfaces are modified, new bathroom waterproofing may be required to comply with building standards.
- Floor reinforcement: Heavier baths, particularly stone or marble designs, may require structural floor support to safely carry the additional weight.
- Bathroom access: Limited access to the bathroom, such as narrow hallways or staircases, can increase installation time and labour requirements.
- Removal of the existing bath: Replacing an old bath often involves demolition and disposal, which can add to the overall bath replacement cost.
These factors can influence the total bathroom renovation budget, especially when replacing multiple fixtures or altering the layout. Bath installation is often just one part of a larger renovation project.

Inset vs Freestanding vs Back-to-Wall Baths
Choosing between inset baths, freestanding baths, and back-to-wall baths often comes down to budget, bathroom layout and personal design preferences. Each style offers different advantages depending on your bathroom design and how you plan to use the bath.
Inset Baths
- usually the most affordable option
- simplest installation because they are built into a wall or tiled hob
- commonly used in family bathrooms and shower-bath combinations
Freestanding Baths
- create a strong visual feature in modern bathrooms
- can be positioned more flexibly within the room
- may involve slightly higher installation costs due to plumbing positioning

Back-to-wall Baths
- provide the modern appearance of a freestanding bath
- sit flush against a wall for easier cleaning
- work well in bathrooms where space is limited
Many homeowners choose back-to-wall baths for their practical balance of style and functionality. They deliver the look of modern bath designs while remaining easier to install and maintain than fully freestanding units.

Getting the Best Value Bath for Your Renovation
Choosing the right bath isn’t only about the purchase price. The best approach is to consider how the bath fits within the overall bathroom layout and renovation plan. Selecting the correct size ensures the bath suits the available space while still providing comfortable use for everyday bathing.
It’s also important to understand installation costs before purchasing. A straightforward bath replacement is usually the most affordable option, while moving plumbing or altering the bathroom layout can increase the overall cost. Planning these details early helps avoid unexpected expenses during the renovation.
Comparing bath materials and styles is another key step. Acrylic baths remain one of the most practical options because they offer good durability, comfort and affordability. This balance makes them a popular choice for many homes in Perth.
