How Are Above Ground Pools Made?
Ever wondered how that portable small swimming pool in your garden comes together?
Short answer: sturdy walls, a vinyl liner, and a splash of clever assembly.
But there’s more going on beneath the surface than meets the eye.
From raw materials to a fully kitted-out pool, there’s a whole journey behind the fun.
Let’s dive into it—without getting your feet wet.
From Raw Materials to a Complete Pool Kit
The Manufacturing of Pool Components
Shaping the Galvanised Steel or Resin Frame
It all starts with the bones of the pool.
Whether you're building a compact splash pool or something big enough for cannonballs, the frame needs to be strong.
Most above ground pools use galvanised steel or moulded resin.
Why? Because they’re tough, rust-resistant, and can handle years of wild summer weather—especially the kind we get in the UK.
The steel is shaped into interlocking panels or rails, while resin parts are precision-moulded to fit together like a jigsaw.
It’s not just strength—it’s smart design.
Producing the Durable Vinyl Liner
Now, every pool needs a liner to hold the water.
That’s where vinyl comes in.
Think of it as the waterproof skin that lines the inside of the frame.
It’s thick, flexible, and specially treated to resist sun damage, mould, and all the wear and tear that comes with daily use.
Some liners even have patterns printed on them—like mosaic tiles or pebbles—so your pool looks as good as it feels.
Assembly and Installation
Step-by-Step Pool Construction
Once the parts are packed and shipped, it's time for the real magic: assembly.
It all begins with prepping the ground (more on that in a second).
Then comes the frame—walls first, floor rails next, then the liner.
After that, it’s all about installing the pump, filter, and accessories.
It might sound like a big job, but many families do it over a weekend.
We know one dad from Surrey who had his set up in just two days—with only a spade, a spirit level, and a bit of help from YouTube.
The Role of a Level Base and Ground Prep
This bit? Absolutely crucial.
If your base isn’t level, your pool won’t be either—and that’s asking for trouble.
A lopsided pool puts uneven pressure on the frame, which could lead to damage or leaks down the line.
Most people clear the grass, level the soil, and lay down a layer of sand or foam padding.
It might take a bit of effort, but trust us—it’s the secret to a safe, sturdy pool that lasts all summer.
The Different Types of Pool Kits
Pre-Packaged Kits for DIY Installation
Not keen on hiring a professional? You’re not alone.
These days, most above ground pools come in DIY-friendly kits.
They’re boxed up with everything you need—from frame parts and liner to filters, hoses, and even a ladder.
No guesswork. No trips to the hardware store.
Just unpack, follow the instructions, and enjoy the build.
What to Expect in a Standard Pool Kit
Most kits are pretty generous.
You’ll usually get:
-
The steel or resin frame
-
A vinyl liner
-
Pump and filter
-
Safety ladder
-
Ground cloth or floor pad
-
And sometimes a pool cover, too
Some kits even throw in extras like a maintenance kit or a floating chlorine dispenser.
Everything’s packed with ease in mind—so you’re not scrambling to source parts halfway through.
The Difference Between Bead and Overlap Liners
Now, when it comes to liners, you’ve got two main types: bead and overlap.
Bead liners clip into a track around the pool edge—giving a clean, professional finish.
Overlap liners do exactly what they say on the tin—they drape over the edge and are secured with clips.
Overlap liners are often easier for first-timers and can be more forgiving if your measurements are slightly off.
Bead liners, though, tend to look a bit sleeker and make liner replacements quicker.
Both do the job—it’s just about choosing what suits your setup best.
