Fibreglass vs Concrete Pools: Which One Is Right for You?

Designing your dream pool is about more than just size and shape — it’s about creating your perfect piece of paradise at home. But one big decision can shape the entire journey:
Do you go with fibreglass or concrete?

At Advance Pools, we’re here to help you make the right decision with clear, honest guidance. In this guide, we break down the key differences between fibreglass and concrete pools, so you can choose what works best for your home, lifestyle, and budget.

What Are Fibreglass Pools?

Fibreglass pools are pre-moulded shells built off-site in a controlled factory environment, then delivered and installed at your home. The structure is made of several layers of high-strength fibreglass and coated with a smooth, non-porous gel layer that helps resist algae and stains.

They’re quick to install, low-maintenance, and exceptionally durable — when built with the right materials.

🔍 Important Note: Not all fibreglass pools are created equal.
For true strength and long-term peace of mind, fibreglass pools must be manufactured using ISO-certified resin that is Lloyd’s of London approved. This certification guarantees the resin meets the highest global standards for marine-grade durability, chemical resistance, and structural stability.

At Advance Pools, we only use ISO-certified resins supplied by NCS Resins — the trusted name in the industry. It’s a critical part of what makes our pools stronger, safer, and longer-lasting than cheaper alternatives.

What Are Concrete Pools?

Concrete (or gunite/shotcrete) pools are constructed entirely on-site. A steel rebar framework is built, and then a mixture of concrete and sand is sprayed or poured to form the shell. Once cured, the pool is finished with plaster, tiles, or pebbles.

While concrete pools offer full customisation, the process is labour-intensive, slower, and comes with higher long-term maintenance needs.

Fibreglass vs Concrete Pools: The Breakdown

💸 Cost Comparison

Upfront Cost:
Fibreglass pools are typically more affordable to install. With pre-made shells and streamlined installation, you save on labour and time.

Long-Term Savings:
Thanks to their smooth, non-porous surface, fibreglass pools need fewer chemicals and much less cleaning. They also avoid expensive resurfacing — something concrete pools often require every few years.

Winner:
Fibreglass pools offer better value over time — less hassle, fewer costs, more swimming.

🧼 Maintenance & Durability

Less Scrubbing, More Swimming:
Fibreglass pools don’t allow algae to embed into the surface. That means less brushing and fewer chemicals.

Built Tough:
When manufactured with ISO-certified resin (like ours), fibreglass pools are incredibly strong, flexible, and long-lasting — perfect for South Africa’s climate and soil movement.

🎨 Aesthetic & Design Options

Fibreglass Pools:
Available in a wide range of elegant, pre-designed shapes and finishes — perfect for fast, stylish installations.

Concrete Pools:
If you need a totally custom design with complex features, concrete is more flexible — but comes at a cost.

🌱 Environmental Considerations

Fibreglass pools are the more sustainable choice:

• Fewer chemicals needed

• Lower energy use (better insulation)

• Shorter filtration cycles

• Smaller carbon footprint over the pool’s lifetime

☀️ Climate Performance

Fibreglass handles extremes well.
It resists cracking in freeze-thaw conditions and stays cool underfoot during hot summers — making it ideal for just about any part of South Africa.

Final Thoughts: Why Fibreglass (When Done Right) Wins

Both pool types have their place — but when it comes to fast installation, low maintenance, cost-effectiveness, and long-term durability, fibreglass is the clear winner for most homes.

That said, the resin used in manufacturing makes all the difference. Many lower-cost fibreglass pools are made with sub-standard or uncertified resins — leading to colour fading, structural cracks, or chemical failures down the line.

At Advance Pools, we only build with premium ISO-certified resin, Lloyd’s of London approved, and supported by our trusted DEXA™ material technology:

• DEXA™RES – High-strength polyester resin

• DEXA™GUARD – Vinyl ester resin for chemical resistance

• DEXA™COAT – Long-lasting gelcoat for beauty and protection

• DEXA™TONE – Colour pigments that stay vibrant for years

And it’s all backed by our 15-Year Inground Structural Warranty.
