Why Concrete Still Beats Fibreglass for Brisbane Pools

We get this question every week, usually from clients who've been quoted by a fibreglass company first and are trying to work out whether the extra cost of concrete is worth it.

Quick answer: usually yes. Long answer below — and we'll be honest about where fibreglass actually wins too.

What you're actually buying with concrete

A concrete pool — what we build — is a custom shell formed in steel and sprayed with shotcrete to a minimum 200mm thickness. It's reinforced, engineer-inspected before the spray, and finished with pebble-crete or tile.

A fibreglass pool is a mass-produced one-piece shell, made in a factory, trucked to your block, and dropped into a hole. There are good fibreglass companies and bad ones, but the shell itself is what it is — you can't change the shape, depth, or size.

The case for fibreglass

Let's not pretend fibreglass has no advantages. It does.

• Faster install — usually 3 to 5 weeks vs 10 to 14 for concrete
• Cheaper upfront — entry-level fibreglass starts around $25K to $35K
• Less initial chemical fuss — the gelcoat surface is smoother than fresh pebble-crete
• Predictable — what you order is what arrives

If you have a small standard block, a tight budget, and no design ambitions beyond 'we want a pool', fibreglass can absolutely make sense. We've recommended it to clients when their site or budget made it the smarter call.

Where concrete wins, particularly in Brisbane

Three reasons most of our clients still choose concrete.

1. You design the pool, the pool doesn't design itself. Concrete lets us match the pool to your yard, not your yard to a moulded shape. Custom dimensions, integrated spa, in-pool seating, sun ledges, exact depth zones — none of that is possible with a one-piece shell.

2. Brisbane sites are rarely flat or simple. Sloping blocks, narrow access, established trees, soil that shifts — these are the rule, not the exception. A concrete pool can be engineered to suit. A fibreglass shell can't always be delivered to the site at all.

3. Longevity matters more than you think. A properly built concrete pool with 200mm walls and steel reinforcing should outlive your house. Fibreglass shells have a real lifespan — the gelcoat fades, the surface chalks, and major repairs are difficult because you can't just patch a structural fault in one panel.

The cost gap is smaller than it looks

People quote us $35K fibreglass vs $50K concrete and assume concrete is 40% more expensive. In practice, by the time the fibreglass quote includes excavation, fence, paving, electrical, and a proper coping detail, the gap narrows considerably.

Our Plunge Pool (5×3m) sits at $35,900 turnkey — directly comparable to fibreglass entry pricing — and that's a fully custom concrete build with the same Zodiac/Waterco gear we put on a $70K pool.

One thing we won't do

We won't try to talk you out of fibreglass if it's the right call for your situation. We do enough work that we don't need to win every quote. What we will do is walk through the comparison honestly so you can decide with full information.

If you're stuck between two quotes, send them through. We'll do an apples-to-apples breakdown — without the sales pressure.
