At Plunge Pools Perth Builders, we do more than install pools—we create stunning outdoor spaces built for relaxation and style. With years of experience and a deep understanding of Perth’s climate and regulations, we make the installation process seamless, efficient, and tailored to your space.
This guide breaks down exactly what you’ll pay and what affects pricing. From council approvals to site prep and installation challenges, everything you need to know is here. Let’s get started.
Plunge Pools: Small Footprint, Big Impact
A plunge pool isn’t about swimming laps. It’s about cooling off, relaxing, and adding luxury to your backyard—without the maintenance nightmare of a full-sized pool. Ranging from 2 to 7 metres long and up to 2 metres deep, they’re perfect for tight spaces, especially in urban Perth homes where every square metre counts.
Why More Perth Homeowners Are Choosing Plunge Pools
Perth’s summers are brutal. A traditional swimming pool costs a fortune to install and maintain, but a plunge pool gives you the same refreshing escape for a fraction of the price. More homeowners are making the switch because:
- Uses Less Water – Ideal for Perth’s water restrictions.
- Sleek, Modern Aesthetic – Blends perfectly with high-end landscaping and alfresco areas.
- Energy-Efficient – Heats up faster, stays warm longer, and costs less to run (especially with solar heating).
How Much Does a Plunge Pool Cost in Perth?
Disclaimer: Pricing estimates in this guide are based on average client projects completed in Perth as of January 2026. Final costs may vary depending on site-specific conditions, material selections, and council regulations.
In Perth, most completed plunge pool projects end up closer to the $50,000 mark once installation, compliance, and essential extras are included. While base pool pricing can appear lower at first, fencing, heating, electrical work, access logistics, and site preparation often push final costs higher than many homeowners initially expect.
Fibreglass plunge pools with upgrades such as heat pumps, integrated spas, and premium finishes commonly move into the $60,000 to $70,000 range. Custom concrete plunge pools can vary significantly, with final pricing largely influenced by design complexity, site conditions, and how much of the project is professionally managed rather than staged.
Fibreglass Plunge Pools: Affordable & Low Maintenance
- Price Range: $40,000 – $60,000 (installation included)
- Installation Time: 1 to 3 weeks
- Best For: Homeowners who want quick installation and low maintenance
Why Choose Fibreglass?
- Pre-fabricated shells mean installation is fast and efficient.
- Smooth, non-porous surface prevents algae growth and reduces chemical use.
- Available in standard shapes and sizes, so no design headaches.
Downsides?
- Less customisation than concrete.
- May need crane access for delivery, which adds to costs.
While fibreglass plunge pools are often promoted as the most cost-effective option, final pricing can be similar to concrete builds once heating, fencing, electrical work, and access requirements are included. In Perth, site conditions and the level of finishing around the pool often have a greater impact on total cost than the pool material itself.
Precast Concrete Plunge Pools: The Middle Ground
- Price Range: $30,000 – $40,000 (excluding installation)
- Installation Cost: $10,000 – $20,000 (site access & crane use affect pricing)
- Total Cost: $40,000 – $60,000 (including installation & labour)
- Installation Time: 2 to 4 weeks
- Best For: Homeowners who want concrete durability with a faster build time
Why Choose Precast Concrete?
- Factory-made and delivered to your site for quick installation.
- Stronger than fibreglass and can be partially or fully in-ground.
- More premium look than fibreglass, without the high cost of a fully custom build.
Downsides?
- Less design flexibility than custom concrete pools.
- Heavier than fibreglass, so proper site preparation is essential.
Custom Concrete Plunge Pools: Fully Custom, Built to Last
- Price Range: $50,000+ (varies by design)
- Installation Time: 6 to 12 weeks
- Best For: Homeowners who want a unique, high-end pool tailored to their space
Why Choose Custom Concrete?
- Unlimited design options—choose the size, shape, and depth that fits your vision.
- Luxury finishes available, from tiles to waterfalls and built-in seating.
- Extremely durable and adds long-term property value.
Downsides?
- Takes the longest to install—expect a build time of 6 to 12 weeks.

Factors Affecting Plunge Pool Costs in Perth
The price of a plunge pool isn’t just about the pool itself. Excavation, site conditions, installation complexity, and additional features all impact the final cost. Understanding these factors helps you budget smarter and avoid surprise expenses.
Site Preparation & Soil Conditions
Not all backyards are the same. Perth’s sandy soil is easy to work with, but if your property sits on rocky or clay-heavy ground, excavation costs rise fast.
- Excavation Costs: Expect to pay $1,500 to $5,000, depending on soil type and site accessibility.
- Sloped Blocks Need Extra Support: Retaining walls or concrete footings may be required, increasing costs.
Installation Challenges in Perth
Some sites are straightforward. Others? Not so much. Tight access, crane requirements, and electrical setup can all add to your final bill.
- Crane Requirements: If a truck can’t access your site, a crane may be needed to lift and place the pool. Cost: $3,000 to $10,000.
- Plumbing & Electrical Setup:
- Power supply for filtration, heating, and lighting: $1,000 to $5,000.
- Licensed electrician and plumber required to meet WA building codes.
Additional Costs & Custom Features
Adding extra features can enhance your plunge pool experience, but will also increase costs.
| Feature | Estimated Cost |
|---|---|
| Heating (solar, gas, or electric) | $1,600 – $3,600 |
| LED lighting | $100 – $400 per light |
| Hydrotherapy jets | $80+ per jet |
| Automated pool covers | $7,000+ |
| Water features (e.g., waterfalls, fountains) | $1,000 – $4,400 |
| Custom tiling & finishes | Varies |
Installation timelines and costs can vary significantly between states due to access, soil conditions, and council approvals. Homeowners comparing Perth builds with east coast projects often notice these differences when reviewing guidance from this company operating in Brisbane.
Top 5 Things We Wish Every Perth Homeowner Knew Before Installing a Plunge Pool
- The Pool Shell Isn’t the Final Price
Many assume the listed price covers everything. But access issues, fencing, and landscaping often double the base cost. - You Might Need a Crane
Tight-access backyards are common in Perth. Even a small pool may need crane delivery, adding thousands to the total. - Approvals Can Delay Your Timeline
Council approval in WA can take up to 6 weeks. Start early and don’t book installation before approval is finalised. - Glass Pool Fencing is Expensive but Worth It
It’s sleek and compliant but can cost over $600 per metre. However, it significantly improves property value and aesthetics. - Energy Efficiency Starts with Good Design
Position your pool to catch the sun, invest in insulation, and opt for solar heating from day one to save long-term.
Common Budget Blowouts We See on Perth Projects
Budget overruns most commonly occur when site works and compliance requirements are underestimated. Relocating underground services, removing trees, upgrading fencing, or adjusting ground levels for drainage can all add unexpected costs if they are not identified early.
These items are rarely obvious during online research but become clear during professional site inspections, which is why early planning plays a key role in accurate budgeting.
Why Final Costs Often Exceed Initial Pool Quotes
One of the most common misconceptions we see is assuming the pool shell represents the majority of the project cost. In reality, access requirements, fencing, electrical compliance, and surrounding works frequently match or exceed the cost of the pool itself.
Landscaping, decking, paving, and compliant fencing regularly add substantial costs to Perth plunge pool projects, particularly where glass fencing or integrated outdoor entertaining areas are involved. Allowing for these elements early helps avoid budget surprises once installation is underway.
Perth-Specific Installation Costs & Process
The cost of installing a plunge pool isn’t just about the pool itself. Site prep, excavation, plumbing, electrical work, and landscaping all play a role in the final total price.
Here’s what the installation process looks like and what you’ll be paying for.
1. Site Preparation & Excavation
Before installation begins, the site needs to be cleared and levelled. Excavation costs depend on soil conditions and accessibility.
- Standard excavation: $1,500 – $5,000, depending on soil type.
- Difficult access: If mini-excavators or manual digging are required, costs go up.
- Sloped sites: May need retaining walls or structural reinforcements, adding to expenses.
2. Plumbing & Electrical Work
A licensed plumber and electrician are required to install filtration, heating, and lighting systems.
- Plumbing setup: $1,000 – $3,000
- Electrical installation: $1,500 – $5,000
- Heating systems, LED lighting, and automation add to costs but improve efficiency.
3. Pool Shell Installation & Finishing
How your pool is installed depends on the type:
- Fibreglass Pools: Delivered as a pre-made shell and placed into position using a crane if necessary.
- Precast Concrete Pools: Delivered and installed onto a prepared foundation.
- Custom Concrete Pools: Built on-site, with the concrete poured and cured over several weeks.
4. Landscaping & Final Touches
A plunge pool alone is great, but the surrounding decking, paving, and garden features take it to the next level.
- Basic landscaping: Starts at $1,500.
- Premium finishes: Can exceed $5,500, depending on materials and design.
Once installation is complete, your pool will be filled, tested, and inspected to ensure it meets WA safety and compliance standards.
Climate & Energy Efficiency Considerations
Perth’s summers are brutal. A full-sized pool bleeds water through evaporation, racks up energy bills, and takes forever to heat. A plunge pool? Uses less water, heats faster, and costs less to maintain.
Energy-Efficient Features That Cut Costs
A plunge pool is already cheaper to run than a full-sized pool, but the right features can reduce running costs even further.
| Feature | Benefits | Estimated Cost |
|---|---|---|
| Solar heating | Uses free energy from the sun to heat your pool | $3,000 – $5,000 |
| Insulated fibreglass pools | Retains heat better, reducing heating costs | Included with fibreglass pools |
| Variable-speed pool pumps | Uses less energy than standard pumps | $800 – $2,000 |
| Automated pool covers | Reduces heat loss and evaporation | $7,000+ |
| Saltwater chlorinators | Requires fewer chemicals and less maintenance | $1,500 – $3,000 |
How to Reduce Water & Energy Costs
A plunge pool already costs less to run than a full-sized pool, but small tweaks can cut costs even further.
- Use a pool cover – Cuts evaporation by up to 50% and keeps heat in.
- Go solar for heating – One-time investment, zero ongoing energy costs.
- Run your pump during off-peak hours – Reduces electricity bills.
- Upgrade to a variable-speed pump – Uses up to 80% less power than standard pumps.
Local Regulations & Pool Compliance in Perth
Plunge pools aren’t just about installation. They need to meet WA’s safety standards, require council approval, and must have compliant fencing. Skip this step, and you’re looking at fines of up to $5,000.
Do You Need Council Approval for a Plunge Pool in Perth?
Yes. Most plunge pools require local council approval before installation. The process includes:
- Submit a building application to your local council.
- Ensuring compliance with WA safety standards, including fencing laws.
- Booking a final inspection before use.
Approval Timeframe: 2 to 6 weeks, depending on council workload.
WA Pool Fencing Laws & Safety Requirements
All pools in WA must meet Australian Standard AS1926.1. The key rules:
- The fence must be at least 1.2m high.
- Self-closing, self-latching gate required.
- No climbable objects within 900mm of the fence.
- The fence must fully enclose the pool and separate it from the house.
Estimated Costs for Pool Fencing
| Fencing Type | Cost per Metre | Features |
|---|---|---|
| Aluminium fencing | $250 – $400 | Affordable, durable, and easy to maintain |
| Frameless glass fencing | $600 – $700 | Modern, stylish, and provides an unobstructed view |
| Semi-frameless glass fencing | $400 – $600 | A balance between affordability and aesthetics |
Failing to comply with WA pool fencing laws can result in fines of up to $5,000, so it’s essential to follow regulations from the start.
Maintenance & Running Costs
A plunge pool costs less to maintain than a full-sized pool, but there are still ongoing expenses for cleaning, filtration, and heating. The good news? With the right setup, you can keep costs low and predictable.
Annual Maintenance Costs
The average yearly cost to maintain a plunge pool in Perth ranges from $1,000 to $1,400, covering:
| Expense | Annual Cost | How to Reduce Costs |
|---|---|---|
| Pool Chemicals | $300 – $600 | Use a saltwater chlorinator to cut chemical use |
| Filtration & Pump Electricity | $400 – $800 | Upgrade to a variable-speed pump for 80% energy savings |
| Water Top-Ups (Evaporation Loss) | $100 – $200 | Use a pool cover to prevent water loss |
| Cleaning (Tools or Pro Services) | $200 – $400 | Invest in a robotic pool cleaner instead of hiring professionals |
Higher-than-expected running costs are usually linked to design or equipment shortcuts rather than the plunge pool itself. Inadequate pump sizing, inefficient heating systems, or the absence of a pool cover can significantly increase electricity and water usage over time.
Well-designed plunge pools with efficient equipment and appropriate covers generally maintain stable and predictable running costs year after year.
Water & Energy Usage Costs in Perth
- Evaporation is a problem—especially in summer. A pool cover can cut water loss by up to 50%.
- Solar heating is the cheapest option—once installed, it costs nothing to run.
- Electric heating? Expect a $50 – $150 monthly increase on your power bill.
- Variable-speed pumps use up to 80% less power than standard pumps, saving money in the long run.
Cost-Saving Tips for Maintaining a Plunge Pool
A well-maintained plunge pool costs less to run and lasts longer. Smart maintenance keeps your pool clean, efficient, and hassle-free without blowing your budget.
- Run the pump during off-peak hours – Cuts electricity costs.
- Use a robotic pool cleaner – One-time investment that saves on cleaning services.
- Monitor pH and chlorine levels weekly – Prevents expensive chemical imbalances.
- Switch to a saltwater system – Lower chemical costs, less maintenance, and gentler on skin.
Stick to these strategies, and owning a plunge pool stays affordable year after year.
