  • The choice of manufacturer is essential: warranties, support, technical expertise, and follow-up.

What is a shell pool?

Theshell pool, sometimes called aone-piece pool, is a prefabricated basin manufactured in a factory and then delivered directly to your home to be installed in theexcavation pitprepared for this purpose. Unlike a concrete pool, which is built piece by piece on-site, it arrives already molded and ready to install. The result: a considerably reduced construction site and swimming possible in just a few days.

The most common model is thefiberglass shell pool, which is attractive due to its excellent value for money and robustness. It is composed of several technical elements:

  • A structure made of fiberglass and polyester resin,
  • A protective coating, the coat,
  • Structural reinforcements to ensure its long-term solidity.

Thanks to this design, polyester shell pools offer a uniform, perfectly watertight basin that is easy to maintain and durable.

The polyester shell pool, a model with many advantages

Quick to set up

After the earthworks and preparation of thetrench bottom, the shell is delivered in one piece and then installed directly into the excavation.

In just a few days, thanks to a final implementation and simplified hydraulic connections, theswimming pool installation is complete and the pool is ready to be filled.

Proven durability

Made fromfiberglassand polyester resin, the hull is protected by a layer ofgel coatwhich ensures watertightness and preserves its shine. This trio of materials guarantees excellent resistance to shocks, ground movement, and climatic variations.

With regular maintenance and goodwater treatment, the pool retains its solidity and aesthetics in the long term.

Customizable aesthetics

Available in round, rectangular, oval, or freeform shapes,polyester shell poolsoffer a wide choice of sizes and colors.

You can then enhance the whole thing with installation of coping stones and landscaping around the pool, for a customized look that enhances your outdoor space.

Competitive pricing

The construction of a shell pool is often more affordable than a concrete pool, while offering comparable durability. Considering its quick installation, longevity, and low maintenance, it is a sustainable and profitable investment for your pool projects.


Shell pool: construction explained step by step

Theconstruction of a polyester shell swimming poolis not improvised: it follows a precise and rigorous process that guarantees the stability, watertightness, and durability of the pool. Here are the main steps:

1. Site survey and model selection

Everything begins with a site analysis carried out by a professional: soil type, sunlight, access for thedelivery of the pool, any technical constraints. This is also the time to define your project: shape, dimensions, depth, and shell options.

This choice is crucial to ensure that the pool fits perfectly around the basin and meets your aesthetic and practical expectations.

2. Earthworks and soil preparation

Thefoundation pitis then dug to the exact dimensions of the hull. The ground must be leveled and compacted to avoid any risk of movement or subsidence.

This preparatory stage determines the success of theswimming pool installation in the long term.

3. Setting up the gravel bed

A bed ofcrushed gravelis laid at the bottom of the excavation. This draining support plays an essential role: it stabilizes the shell, prevents water stagnation, and ensures a solid and homogeneous base.

4. Delivery and installation of the hull

The pool delivery is made by truck, sometimes with a crane to place the shell directly into the excavation.

The operation is quick but spectacular: in just a few minutes, the hull finds its final resting place in the ground.

5. Calibration and leveling

Once in place, the hull is wedged and aligned with millimeter precision.

This adjustment ensures that the pool is perfectly straight and stable, which is essential for good water circulation and the final appearance.

6. Hydraulic and electrical connections

Now is the time to connect essential equipment:

  • Underground tanks, skimmers, and return jets
  • Installation of the filtration system in the technical room,
  • Hydraulic connectionsto ensure optimal water treatment,
  • Electrical connections for lighting, heat pumps, or any other comfort equipment.

7. Backfilling and filling

The basin is gradually surrounded bycrushed gravel(backfilling) at the same time as it is filled with water. This dual operation balances the pressures exerted inside and outside the hull, thus avoiding any risk of deformation.

8. Installation of coping stones and finishing touches around the shell

Final step: theinstallation of the coping stones, which dress the edge of the pool and ensure an elegant finish. Then come the landscapingaround the pool: terrace, wooden deck, planting… These finishes transform your garden into a true relaxation area.
