Are Above Ground Pools Fiberglass?
Thinking of above ground pools installed and picturing a plastic paddling tub? Think again.
Yes, some above ground pools are fibreglass—tough, sleek, and built to last. But they’re not all the same.
If you're dreaming of a durable pool that won't rust, won't demand constant upkeep, and still looks good in the garden, you might be tempted by fibreglass. But before you start digging (or buying), there are a few things you’ll want to know.
Let’s break it down—without the jargon.
Understanding Fibreglass Pools
What Fibreglass Pools Are Made Of (Moulded Composite Shell)
Fibreglass pools start life in a factory, not your garden.
They’re made from glass fibres mixed with resin, poured into a mould, and cured into a solid shell. Think of it like a giant bathtub—but built to hold thousands of litres of water, year after year.
The result? A smooth, sturdy shell that’s built to last, even through the Great British weather.
Primary Application: Inground Pools
Here’s the thing—fibreglass pools were never really designed to sit above ground.
They're typically used for inground setups, where the earth around them helps support their shape. Once lowered into a prepared hole, they stay put, with soil acting as natural reinforcement.
It works brilliantly—when it’s done right.
Advantages of Fibreglass (Durability, Low Maintenance, Smooth Surface)
Why do people rave about fibreglass pools?
Because they’re tough. They don’t rust, crack easily, or soak up algae like concrete can. And that slick, smooth finish? It’s kind to little feet and makes cleaning a breeze.
For busy families who want to enjoy the pool without becoming full-time maintenance crew, that’s a big win.
Why Fibreglass is Not Standard for Above Ground Pools
Structural Differences Between Inground and Above Ground Construction
Here’s where things get tricky.
Above ground pools need to hold their shape without help from the ground. They’re freestanding. But fibreglass shells? Not really built for that.
Without solid support around them, they can flex or crack under pressure.
Challenges in Manufacturing a Freestanding Fibreglass AGP Shell
Building a fibreglass shell strong enough to sit fully above ground is possible—but expensive.
It means thicker walls, extra supports, and more complex manufacturing. All of that pushes up the cost, which is why most pool makers stick to easier, cheaper materials like steel or resin for above ground builds.
That’s why fully fibreglass above ground pools are more of a rarity.
Transportation and Installation Complexity for Large Shells
Then there’s the matter of delivery.
These shells are huge. Getting one into your garden often means cranes, permits, or removing fence panels—not something you can sort on a Saturday morning.
And installation? You’ll need pros who’ve done it before. Definitely not a DIY job unless you're part superhero.
Common Materials for Above Ground Pools
Not all above ground pools are created equal. Some are built to last for years, others are great for a summer or two.
Let’s take a look at what’s out there.
Steel Wall Above Ground Pools
Construction and Durability
Steel wall pools are the go-to classic.
They’ve been around for decades and for good reason—they’re solid. Steel panels lock together to form a frame that can handle water weight with ease.
Most are treated with coatings to fend off rust, so they can survive a good few British winters.
Liner Integration (Vinyl)
Inside the steel frame sits a vinyl liner. That’s what holds the water and gives the pool its smooth, finished look.
Vinyl liners can wear over time, but the good news is they’re replaceable—so the pool itself lasts longer.
Resin Frame Above Ground Pools
Corrosion Resistance and Lifespan
If you’re worried about rust or want something that can handle saltwater, resin is a solid choice.
Resin frames don’t corrode like metal can, and they’re often lighter too. Plus, they don’t heat up in the sun like steel does—no more sizzling fingers on hot summer days!
Hybrid Pool Designs
Many of today’s best above ground pools use a mix of resin and steel.
You get the strength of metal with the rust-resistance of resin. It's a clever blend that gives families the best of both worlds without breaking the bank.
Alternative Above Ground Pool Types (Brief Mention)
Inflatable or Soft-Sided Pools
Inflatables are quick, fun, and perfect for a heatwave.
They’re cheap, easy to set up, and just as easy to pack away. But they’re not made for the long haul.
One sharp stick and it’s game over.
Wooden or Modular Panel Pools
Want something that looks a bit more stylish?
Wooden or modular panel pools can blend nicely into a garden. They’re semi-permanent, often pricier, but give a more custom feel.
Some even let you add decking or seating around the edges—great for parties or just kicking back with a cold drink.
