Thinking about putting a pool in? One of the first decisions you’ll face is the big one: concrete or fibreglass. Both will get you swimming, but they’re very different beasts — especially here in Tropical North Queensland, where the soil, heat, and weather put every pool to the test.
At Cairns Precision Pools, we build concrete pools, and we’re not shy about why. Below is an honest look at how the two stack up — and why, for most Cairns homes, concrete comes out on top.
The Quick Answer
Fibreglass pools are cheaper upfront and faster to drop in. But when it comes to durability, design freedom, and long-term value, concrete wins on nearly every front. If you want a pool built around your backyard — not the other way around — concrete is the clear choice.
1. Design Flexibility
A fibreglass pool is a pre-moulded shell. You’re choosing from a catalogue of fixed shapes and sizes, and your backyard has to accommodate the shell — not the reverse.
Concrete has no such limits. Any shape, any depth, any size. Want an infinity edge, a beach entry, a built-in spa, or a custom plunge pool squeezed into a tricky block? Concrete makes it happen. For sloping sites and unusual yards — common around Cairns — that flexibility is a genuine game-changer.
Winner: Concrete
2. Durability in Tropical Conditions
This is where Cairns really matters. Our soil moves, our wet season is intense, and the heat is relentless. Fibreglass shells can flex, and in reactive soils they’re more prone to issues like bulging or movement over time.
A properly engineered concrete pool is built solid and built to stay put. With a 40+ year lifespan, it’s designed to handle tropical ground conditions and keep performing decade after decade.
Winner: Concrete
3. Finish and Look
Fibreglass comes with a gel-coat finish in a limited range of colours. It looks fine — but it’s the same look you’ll see in plenty of other backyards.
Concrete pools are finished with pebble or tile, so you control the exact colour of the water and the feel of the whole space. From bright tropical blues to deep, moody blacks, your finish sets the mood. It’s the difference between a pool that fits in and a pool that stands out.
Winner: Concrete
4. Upfront Cost
Here’s the one area fibreglass genuinely leads. A fibreglass pool is usually cheaper to buy and quicker to install, because the shell is manufactured offsite and craned in.
If the lowest possible upfront price is your only priority, fibreglass has the edge.
Winner: Fibreglass
5. Long-Term Value
Cheaper to install doesn’t always mean cheaper to own. Concrete pools are widely seen as a premium feature that adds real value to your property — and because they’re built to last, you’re far less likely to be dealing with shell replacement or resurfacing headaches down the track.
For most homeowners, a concrete pool is an investment in the home, not just a summer purchase.

The Verdict
Fibreglass has its place — if budget and speed are everything, it’s a reasonable option. But for a pool that’s built around your backyard, handles Cairns conditions, looks exactly how you want, and lasts for decades, concrete is the clear winner.
That’s what we do. Every pool we build is engineered and finished to exacting standards — no shortcuts, no off-the-shelf shells.
