Concrete pools hub
Concrete pools in Australia.
What they cost, how they're built, and whether one's right for your backyard, budget, and lifestyle.
A concrete pool gives you complete design freedom: any shape, any size, any finish. It also costs more, takes longer to build, and requires more ongoing maintenance than any other pool type.
Decision snapshot
Concrete works best when control matters more than speed.

What it is
A fully custom in-ground pool built on site.
A concrete pool is built from steel reinforcement and sprayed concrete, called shotcrete in Australia. Unlike fibreglass pools, which arrive as a pre-made shell, concrete pools are constructed from scratch to your exact specifications.
Every dimension, shape, depth, and finish is chosen by you. That makes concrete useful for irregular slopes, tight access, unusual shapes, or unique architectural requirements that a standard fibreglass shell simply cannot fit.

Build process
How a concrete pool is built.
From breaking ground to your first swim, the build usually takes 12 to 20 weeks depending on council approvals, complexity, and weather.
Typical build timeline
Weeks from breaking ground
Design & approvalsWeeks 0–2 · lead-in
ExcavationWeeks 2–3
Steel reinforcementWeeks 3–4
Shotcrete shellWeeks 4–5
CuringWeeks 5–9 · ~28 days
ServicesWeeks 9–12
Interior finishWeeks 12–15
Fencing & handoverWeeks 15–18
Design and approvals
Step 01 — Design and approvals
Pool design is finalised, a council development application (DA) or complying development certificate (CDC) is lodged, and engineering plans are approved.
Excavation
Step 02 — Excavation
Heavy machinery digs out the pool shell to the specified shape and depth. Soil conditions, drainage, and slope are assessed.
Steel reinforcement
Step 03 — Steel reinforcement
A rebar framework is installed inside the excavation, giving the pool its structural strength.
Shotcrete application
Step 04 — Shotcrete application
Concrete is pneumatically sprayed onto the steel framework at high pressure, forming the pool shell. This typically takes one to two days.
Curing
Step 05 — Curing
The concrete shell cures for approximately 28 days to reach full structural strength.
Services
Step 06 — Services
Filtration systems, pumps, lights, heating, and water features are installed.
Interior finish
Step 07 — Interior finish
The chosen surface finish is applied, usually pebble, render, or tile.
Fencing and handover
Step 08 — Fencing and handover
Compliant pool fencing is installed as required by Australian Standards AS 1926. Final inspection is completed and the pool is filled and balanced.
Costs
Concrete pools are usually the most expensive pool type to build in Australia.
These ranges are a realistic guide for a standard inground concrete pool, excluding fencing, landscaping, and heating.
| Pool size | Approximate cost (AUD, ex-GST) |
|---|---|
| Small (5m x 3m) | $50,000 - $70,000 |
| Medium (8m x 4m) | $70,000 - $90,000 |
| Large (10m x 5m+) | $90,000 - $130,000+ |
State variation matters
Labour and material costs are higher in Sydney and Melbourne than in regional areas. Expect to pay a 10-20% premium in capital cities compared to regional NSW, QLD, or VIC.
Typically not included
Pool fencing ($3,000-$8,000), landscaping and paving ($5,000-$30,000+), heating ($3,000-$10,000), pool cover ($1,500-$5,000), and ongoing annual maintenance.
Budget before you commit
Add these costs to your budget planning before you commit.
Finishes
The interior finish changes the look, feel, and maintenance.
Most builders will show you sample finishes. Ask to see completed pools in person rather than relying on brochure photos, as colours and textures look very different underwater.
Most affordable
Render — smooth, simple, shorter lifespan
Wet cement plaster is smooth when new but porous, which makes it more susceptible to algae growth and staining over time. It is the lowest upfront cost option and is typically resurfaced every 10 to 12 years.

Mid-range
Pebble — textured, natural, longer life
A mix of cement and small stones or pebbles gives a textured, natural look. It is harder-wearing than render and is available in a wide range of colours, making it the most common interior choice for new builds.

Premium
Tile — non-porous, premium, design-led
Ceramic or glass tiles are non-porous, easy to clean, and do not need resurfacing in the same way as cement-based finishes. They cost significantly more and require careful installation, and individual tiles can crack if there is ground movement.

Concrete vs fibreglass
Neither pool type is universally better.
The right choice depends on your priorities.
| Feature | Concrete pool | Fibreglass pool |
|---|---|---|
| Upfront cost | $50,000-$130,000+ | $30,000-$70,000 |
| Build time | 12-20 weeks | 3-6 weeks |
| Design freedom | Unlimited: any shape or size | Limited to manufacturer's shell sizes |
| Surface feel | Varies by finish; can be rough if not tiled | Smooth, non-porous |
| Maintenance | Higher: more chemicals, regular brushing | Lower: less algae, fewer chemicals |
| Lifespan | 40-50+ years | 15-25 years before major refinish |
| Resurfacing | Required every 10-20 years ($10,000-$25,000) | Gel coat refinish every 15-25 years |
| Customisation | Complete | Moderate |
You want a specific shape, size, or finish that no fibreglass shell can match, or if you're building a large or architecturally integrated pool.
Budget, speed, and low maintenance are your priorities and a standard size and shape suits your backyard.

Long-term care
Concrete pools cost more to maintain than fibreglass pools.
Total lifetime maintenance cost over 20 years can easily exceed $40,000. Factor this into your overall pool investment calculation, not just the build cost.
Weekly maintenance
Test and adjust pH, chlorine, and alkalinity levels. Brush the pool walls and floor because concrete's porous surface attracts algae more readily than fibreglass. Skim leaves and debris.
Annual costs
Chemicals: $600-$1,200 per year. Professional servicing, quarterly recommended: $400-$800 per year. Energy for pump and heating: $500-$2,000+ per year depending on usage.
Resurfacing
The biggest long-term cost. Render surfaces typically need resurfacing every 10-12 years at $10,000-$20,000. Pebble finishes last longer, usually 15-20 years. Budget for this from day one.

Risk checks
Concrete pools can crack, but it is not inevitable.
Common causes include poor soil preparation, inadequate steel reinforcement, premature or incomplete curing, ground movement, and water table pressure. Understanding the causes helps you ask the right questions when choosing a builder.
Ask your builder about: soil testing, engineering certification, and their approach to curing. Reputable builders will conduct a soil test before quoting and should explain their reinforcement methodology. Look for SPASA-member builders who operate under industry standards.

Lifespan
The shell can last for decades; the finish needs attention.
A well-built concrete pool will last 40 to 50 years or more, significantly longer than fibreglass. The concrete shell itself rarely fails; what needs attention is the interior finish, which will require resurfacing every 10-20 years depending on finish type and maintenance.
If you're planning to stay in your home for decades, or building a pool as part of a property upgrade, the upfront investment can make strong financial sense. If you're likely to sell within 10 years, a fibreglass pool may deliver comparable value with less upfront cost.

Approvals
Most Australian pools need formal approval and compliant fencing.
Every council has different requirements. In most cases you will need either a Development Application (DA) or a Complying Development Certificate (CDC), plus separate approval for pool fencing under AS 1926.
Requirements vary by state and local government area, including setback distances, safety barrier specifications, and inspection processes. Your builder should handle approvals, but it's worth understanding what is involved before you start.

Decision checklist
Is a concrete pool right for you?
Work through these questions before committing. There is no wrong answer; it comes down to what matters most to you.
-
Is the site standard, or tight, sloping, or irregular?
Difficult site → concrete adapts Standard site → a shell drops in -
Do you need a custom shape, size, depth, or finish?
Custom brief → concrete A standard shape suits → fibreglass -
How soon do you need to be swimming?
Timeline is flexible → either works Sooner → fibreglass installs in 3–6 weeks -
What matters more — design control, or lower cost and upkeep?
Design control → concrete Lower cost & upkeep → fibreglass
When a custom design or a difficult site matters most.
When speed, budget, and low upkeep lead the brief.
When it's genuinely balanced — put both in a quote.
A concrete pool likely makes sense if
- You have a non-standard backyard shape, slope, or access constraint.
- You want a specific size larger than standard fibreglass shells, typically capped at around 10m x 4m.
- You want complete control over finish, shape, and integrated features such as beach entry, swim jets, or spa.
- You're planning a long-term stay of 10+ years in the property.
- Your budget comfortably covers both the upfront build and ongoing maintenance costs.
- You value design as a priority and are willing to wait longer for it.
A concrete pool may not be the right fit if
- You need the pool ready quickly; fibreglass installs in 3-6 weeks compared with 12-20 weeks.
- Your budget is tight and you want to minimise ongoing costs.
- You prefer a low-maintenance setup with minimal weekly attention.
- A standard fibreglass shape fits your backyard and design vision perfectly.
Frequently asked questions
Concrete pool questions homeowners ask first.
How much does a concrete pool cost in Australia?
As a planning guide, concrete pools often sit around $50,000 to $130,000 or more before fencing, landscaping, heating, and some surrounding works. The final price depends on size, access, engineering, finish, and location.
Is a concrete pool better than fibreglass?
Not automatically. Concrete offers more design freedom and can suit complex sites, while fibreglass can be faster, more predictable, and simpler to maintain when a standard shell suits the block.
How long does it take to build a concrete pool?
Once approvals and construction scheduling are resolved, a concrete pool build often takes about 12 to 20 weeks. Weather, curing time, site complexity, and finish selection can affect the timeline.
Do concrete pools need resurfacing?
Yes, most concrete pool finishes need attention over time. Render may need resurfacing earlier, while pebble and tile finishes can last longer with proper maintenance.
Can a concrete pool be any shape?
Generally, yes. Because the pool is built on site, concrete can support custom shapes, depths, steps, benches, spas, and ledges, subject to engineering and site constraints.
What does it cost to maintain a concrete pool each year?
As a rough planning guide, budget around $1,000 to $2,000 per year for chemicals, servicing, and running costs. This excludes larger periodic costs such as resurfacing, which is worth planning for separately.
