When it comes to installing a new swimming pool, one of the biggest decisions you’ll face is choosing the right material. In South Africa, two of the most popular options are fibreglass and concrete pools. While both offer unique advantages, they also come with key differences that affect cost, maintenance, design flexibility, and installation time. In this article, we’ll break down the pros and cons of fibreglass vs concrete pools to help you make the right decision for your home and lifestyle.
Cost Showdown: Upfront vs Long-Term Value
Fibreglass pools typically come with a lower upfront price tag due to factory moulding and faster installation. Expect to pay less for labour and materials compared to concrete.
Concrete pools, on the other hand, require custom engineering, site prep, and longer build times—driving the price up significantly.
✅ Winner: Fibreglass for affordability and value over time.
Installation Speed: Quick Dip or Construction Site?
Fibreglass pools can be installed in as little as 7–10 days because the shell arrives ready to go. This makes them perfect for homeowners who want to swim sooner rather than later.
Concrete pools can take anywhere from 6 to 12 weeks to build, depending on weather, permits, and complexity.
✅ Winner: Fibreglass, hands down for speed and minimal disruption.
Maintenance Matters: Easy Care vs Constant Repairs
Fibreglass pools have a non-porous surface, which resists algae and reduces chemical usage. This means lower maintenance costs and less time scrubbing.
Concrete pools, being porous, are prone to algae build-up and require frequent resurfacing and acid-washing over their lifetime.
✅ Winner: Fibreglass for low-maintenance living.
Design Freedom: Custom Shapes or Sleek Simplicity?
Concrete pools offer unlimited design possibilities—any shape, depth, or feature you can dream of is achievable.
Fibreglass pools are pre-moulded, meaning you’ll choose from a range of standard shapes and sizes. While this limits customisation, modern options are still elegant and varied.
✅ Winner: Concrete for design freedom, but fibreglass still impresses with sleek modern lines.
Durability & Lifespan: Built to Last
Fibreglass pools can last 20–30 years with minimal upkeep. Their flexibility allows them to handle ground movement better, reducing cracks and leaks.
Concrete pools are incredibly strong, often lasting 50+ years, but their surface finish may degrade over time and need resurfacing every 10–15 years.
✅ Winner: Tie. Concrete for longevity, fibreglass for low upkeep.
Eco-Friendliness: Going Green
With fewer chemicals, energy-efficient filtration, and less water waste, fibreglass pools are more environmentally friendly.
Concrete pools often require more chemicals and energy-intensive equipment.
✅ Winner: Fibreglass for sustainability.
The Verdict on Fibreglass vs Concrete Pools
Choosing between fibreglass and concrete ultimately comes down to your priorities. If you’re looking for a cost-effective, low-maintenance, and quick-to-install solution, fibreglass is likely your best bet. On the other hand, if custom design and long-term permanence are your main concerns, concrete may be the way to go.
