How Long Do Fibreglass Pools Last?

Purchasing a swimming pool for your home is a big decision, so you want to be sure that the pool you have chosen is not only going to be stress-free to look after, but also stand the test of time to be enjoyed for many years to come. A question that is frequently asked here at Barrier Reef Pools is: how long does an inground pool last?

Quick answer: If you purchase a high-quality fibreglass pool, you can expect it to last 30+ years — and with the right manufacturing, installation, and ongoing care, some fibreglass pools can even last up to 50 years.

Different Pools Have Different Lifetimes

There are a couple of pool options on the market and their lifetime varies.

Vinyl liner pools

Vinyl liner pools are generally the cheapest to set up initially; however, they lack durability and require higher maintenance than others. The vinyl lining generally only lasts for around 10 years before it needs replacing, and the average cost of a vinyl liner replacement is around $4,000. In some cases, you may have to replace the lining well before 10 years due to tears and splits.

Concrete pools

Concrete pools most certainly last longer than vinyl liner pools, although many need resurfacing around 10–15 years later to help prevent algae and bacteria issues. The cost of resurfacing a concrete pool starts at a minimum of $10,000. Concrete pools are porous, which can make them more susceptible to algae and bacteria, meaning more money can be spent on electricity and chemicals. Concrete is also much cooler and requires more time and energy to heat.

Fibreglass pools

Fibreglass pools naturally insulate and heat quicker compared to concrete pools, saving money on energy. If you purchase a high-quality fibreglass pool, you can expect them to last for more than 30 years. Unlike vinyl and concrete, they don’t need replacing or resurfacing. With a Barrier Reef Pools fibreglass pool, you can expect them to last a lifetime — and they come with a lifetime internal, structural and osmosis guarantee.

 

Why Some Fibreglass Pools Last Even Longer

Vinyl Ester Resin = Your Pool Lasting Longer

All Barrier Reef Pools fibreglass pools come fitted with advanced vinyl ester resin. In simple terms, it helps increase the longevity of your fibreglass pool by protecting it from:

• Corrosion
• Water penetration and damage
• Heat-related stress

In addition, Barrier Reef Pools pools are manufactured with advanced gelcoat technology, strengthening the interior surface of your pool and making it harder for algae to take hold.

Our Fibreglass Pools Are Made With 7 Layers of Strength

• Layer 1 – UV and chemical resistant gel interior surface finish
• Layer 2 – Anti-corrosion barrier using the highest quality vinyl ester resin
• Layer 3 – First structural and additional chemical resistant layer using glass fibre
• Layer 4 – Second structural layer using high quality polyester resin and glass fibre
• Layer 5 – Reinforcement layer (additional polyester resin and glass fibre)
• Layer 6 – Outer core laminate with Klegecell/Divonycell sandwich core strengthening
• Layer 7 – Outer sealer coat (high quality waxed polyester resin) to protect the pool layers

Fibreglass pools are designed not to crack — they have a slight flex, so they can better withstand earth movements and extreme temperatures. Concrete pools are more prone to shrinkage cracking, especially when first installed, if the mix has excess water, or if there are intense temperatures and wind during curing.

Barrier Reef Pools exceed Australian Standards for thickness and are the only fibreglass pool manufacturing company with the Australian Standards 5 tick certified product certification. Unlike concrete and vinyl-liner pool companies that often offer shorter warranties, Barrier Reef Pools offer a lifetime structural warranty on all pools.

 

There Are 3 Major Factors That Determine How Long Your Fibreglass Pool Will Last

1) How Your Fibreglass Pool Is Manufactured

Not all fibreglass pools are made the same. The quality of your fibreglass pool depends on the materials used and the workmanship of the manufacturing company. It’s a good idea to use a company that includes a warranty with their fibreglass pool shells. Barrier Reef Pools only use the highest quality materials in a state-of-the-art climate-controlled manufacturing plant.

Pool shells are produced under strict quality assurance measures and exceed Australian (and worldwide) standards for durability and strength. Barrier Reef Pools also use an 8-stage quality control process to manufacture high quality fibreglass swimming pools.

2) How Your Fibreglass Pool Is Installed

It may be tempting to DIY a fibreglass pool installation to save costs, but it comes with major risks — and if things go wrong, the fix can be expensive. To avoid problems such as bulging walls or your pool shifting, ensure you use a licensed pool builder.

Installation needs a flat surface: Ensuring your fibreglass pool is installed on a flat, properly prepared base is critical to its longevity. Uneven ground can create uneven weight load and increase movement-related stress. A properly level base supports even weight distribution, allowing your fibreglass shell to flex with minor earth movement rather than crack.

3) How Your Fibreglass Pool Is Maintained

Pools are filled with water that contains a sanitising solution such as chlorine or salt. They’re exposed to the elements and generally in direct sunlight for a majority of the day. If a pool is neglected (no matter the pool type), the surface can be compromised and problems can arise.

Making sure your pool is filtered and clean is one of the simplest ways to extend its lifetime — but you don’t want to overdose your pool with harsh, strong chemicals, as this can damage the protective surface layer and reduce lifespan.

A few hours of maintenance can mean years of life: Consistent cleaning and balanced chemistry can help your pool stay in great condition for longer. Always use chemicals suited to your pool surface and follow product guidance carefully.

Ways To Extend The Lifespan Of Your Fibreglass Pool

• Use chemical agents designed for your pool (avoid harsh or unsuitable chemicals).
• Clean your pool regularly and keep it covered when not in use.
• Maintain the pool water at a stable, healthy pH level.
• Run your pool filter daily to keep circulation and water clarity consistent.
• Choose a reputable manufacturer and a licensed, experienced installer from the start.

 

Final Thoughts

Overall, the manufacturer, the installer and the pool owner all contribute to the lifetime of the pool. Buying a high-quality fibreglass pool, installing it correctly, and maintaining it well can help your pool last 30+ years — and potentially even longer.
