The concept of the modular swimming pool is simple and revolutionary. It is based on modules prefabricated in the factory (structure, liner, filtration, coping) which fit together on-site, guaranteeing a clean worksite, express installation, and a controlled price. The real asset? Flexibility, it is now possible to enlarge, shrink, or even move one’s pool years after the initial installation. It is no longer a rigid asset, but a living space that adapts to you.

The French Champions of the Pool Kit
France is the undisputed leader of this change, driven by historical companies and new players who compete with ingenuity. The Alsatian Groupe Waterair continues to appeal with its ultra-resistant corrugated steel kits. Designed in Seppois-le-Bas and exported to 29 countries, proving that French quality is synonymous with robustness and ease of assembly.
For its part, Piscines Magiline excels with its iMagiline concept, prefabricated reinforced concrete modules that integrate filtration invisibly. Offering a refined aesthetic and the possibility of easily adding a spa or a counter-current swimming system. Desjoyaux, a pioneer since the 70s, has taken the ecological turn by offering 100% recyclable modular ranges with a recycled plastic structure.
Finally, L’Esprit Piscine establishes itself as the new market star with its high-end kit pools, delivered with design options such as the removable submerged beach and contemporary steps. These innovations demonstrate that modularity now rhymes with quality and durability.

Even in a 6 m² space, the dream of having a pool in the city can become a reality.
The Trends That Make the Difference
Beyond the speed of installation, modular pools set the aesthetic trends for 2025. Gone are the plain blue and classic coping stones. French customers seek perfect integration into their environment. Matte colors are now ultra-trendy, especially anthracite gray, sand, and olive green, which give the pool a natural and contemporary look.
Adaptability translates into innovative options. We note the appearance of submerged beaches or removable islands that allow modulating the depth and relaxation area. Interchangeable flat or progressive bottoms offer increased safety and versatility of use. Finally, the aesthetic is preserved thanks to roller shutters integrated directly into the coping modules, thus eliminating the need for a visible and bulky technical room. These systems contribute to heating efficiency and reduce evaporation, while offering an immaculate pool line.
The Ecological Modular Pool
Ecology is no longer an option, it is an essential purchasing criterion. Modular construction fits perfectly into this sustainable pool approach. The standardization of factory production makes it possible to drastically reduce construction waste. Most manufacturers now use low-carbon concrete, phthalate-free liners, and integrate filtration systems that, divide water consumption by three. Certain ranges, such as Desjoyaux Green and Magiline Éco, go further by displaying certified carbon neutrality, giving these pools the status of eco-responsible equipment.
Proven Flexibility
To illustrate the incredible flexibility of these systems, let’s imagine a family in Bordeaux who, in 2022, had installed a 6 x 3 m pool of the Magiline brand. Three years later, as the family grows, they want to move to a larger dimension without tearing everything up. In 2025, they have two additional modules added to extend the pool to 8m and integrate a 4-seater spa, all without touching the garden or redoing the terrace. The cost of this extension would be estimated to be 40% cheaper than adding an equivalent structure to a traditional poured concrete pool. This is the perfect illustration of the flexible luxury that modular construction allows.
According to the Federation of Pool Professionals (FPP), the success of these structures is dazzling. Modular pools already represent 38% of new installations in France in 2025, a spectacular growth compared to the 12% recorded just five years ago. The projections are clear: this segment is expected to account for 50% of the market by 2030. This popularity is notably explained by the drastic reduction in installation time, which has gone from an average of 8 weeks for traditional to just 9 days for modular models.

In 2025, the French modular pool is no longer a technical compromise, it is the symbol of a contemporary, elegant, and responsible lifestyle. Whether installed in a small suburban garden or a vast Mediterranean villa, it offers the guarantee of healthy water, rapid installation, and, above all, a pool that can evolve with the lives of its owners. It is the promise of an accessible dream, quick to install, and respectful of the environment.
