What it is made of
Every prefab pool we build has four main parts:
- Frame of galvanised steel panels, bolted together to form the walls.
- Braces: steel triangles behind each joint that keep the walls vertical once the pool is full.
- Liner: a watertight PVC membrane covering floor, walls and steps. This is what you see and touch.
- Plumbing and plant room: jets, skimmer or overflow channel, pipes, pump and filter.
More on each part: galvanised panels and pool liner.
Why choose prefab
The main advantage is predictability. The parts have known sizes and strengths, so we know from day one how the pool will behave, and the schedule holds.
The pool is also repairable. If, years later, you want another colour or the liner is tired, only the membrane is changed. The frame stays.
And it travels. Panels stack on a lorry, go on a ferry and reach islands and villages where building on site would be hard.
Which types exist
The same frame makes different pools. What changes is how the water returns to the filter and where the surface sits:
- Skimmer pool: water a few centimetres below the coping.
- Overflow pool: water level with the paving.
- Small pool for courtyards and raised pool above ground.
- Pool on a slope, where the ground falls away.
How long it lasts
The galvanised steel never touches the water, the liner protects it. The frame lasts as long as the house. The liner has a 10-year warranty and, with balanced water, usually lasts longer. See when and how a liner replacement is done.
