Modular systems for swimming pools and water parks: technology, benefits and applications

In the design of a water park, the choice of pools is one of the most important structural decisions. It is not simply an aesthetic choice. It directly affects opening timelines, operating costs, future flexibility and the ability of the park to attract different audiences over the years.

For an operator or investor, a modular swimming pool is therefore not just an alternative construction solution. It is a decision that can influence the entire life cycle of the facility, from construction and maintenance to daily operation and the possibility of expanding or reconfiguring attractions in the future.

In this context, modular stainless steel pool systems offer a practical response to the needs of modern water parks. Myrtha Pools has been developing this technology for over 65 years, with more than 25,000 installations completed in over 80 countries. This international experience makes it possible to apply the same construction principle to sports pools, lagoons, splash parks, slide landing pools, wave pools and high-traffic leisure aquatic spaces.

This guide explains how a modular system for swimming pools and water parks works, what advantages it offers compared with traditional construction methods, which attractions it can support and why the choice of pool structure has a decisive impact on the long-term management of a water park.

In brief
A modular system for swimming pools and water parks is a construction solution based on prefabricated stainless steel panels, manufactured in a controlled factory environment and assembled on site. This technology can be used to create pools for lagoons, wave pools, artificial rivers, splash parks and slides, while reducing construction variables and improving flexibility, maintenance and long-term operation.

A modular swimming pool system is a construction technology based on prefabricated components, designed and manufactured in a factory before being assembled on site through controlled procedures.

In the case of Myrtha technology, the pool structure is made of prefabricated laminated stainless steel panels, mechanically assembled on a concrete slab. The system does not require on-site welding: each panel is fixed through mechanical connections, following a process designed to reduce construction variables and ensure consistent quality, even across very large surfaces.

The waterproofing system is integrated into the panels during production through a hot lamination process. This creates a continuous, uniform and watertight surface, suitable for pools exposed to intensive use.

This feature is particularly important in water parks. Water park pools are exposed to operating conditions that are very different from those of a traditional swimming pool: high daily attendance, continuous variations in water load, dynamic attractions, intensive water treatment and repeated mechanical stress.

A modular stainless steel structure makes it possible to meet these requirements with a pool that is stable, inspectable and designed to perform over time. The industrial prefabrication of components also allows for precise tolerances, reducing the impact of unexpected issues that are often associated with construction work carried out entirely on site.

Reinforced concrete is still widely used in the construction of swimming pools and water parks. In some cases, especially when a project requires extremely complex organic shapes or massive structures, it can remain a valid solution.

However, in high-traffic environments with intensive chemical exposure, stainless steel offers significant advantages. Unlike concrete, it is not subject to structural corrosion and does not present the risk of micro-cracking caused by repeated mechanical stress. This is particularly important in pools exposed to intensive use, where the continuity of the surface and the stability of the structure affect safety, maintenance and the quality of the user experience.

The smooth and uniform surface of modular panels can also contribute to more efficient water management. A more regular, less porous and easier-to-clean pool surface can reduce the accumulation of impurities and simplify routine maintenance.

The advantage of stainless steel should therefore not be considered only in terms of material resistance. It is part of a wider system in which structure, waterproofing, installation, maintenance and quality control work together to create a pool designed for professional use.

One of the most common questions in water park design concerns design freedom: does a modular system limit the shape, size or configuration of the pool?

The answer is no. Modular technology makes it possible to design swimming pools and attractions with different geometries, adapting to the functional and architectural requirements of the project. Stainless steel panels can be shaped and curved to create linear, irregular or organic forms, moving beyond the idea of the modular swimming pool as a standardised or rigidly rectangular structure.

This flexibility is essential in water parks, where areas with very different functions often coexist. A single facility may include family lagoons, children’s play areas, relaxation zones, slide landing pools, current channels, spaces for group activities and visually engaging attractions.

Depths can also be designed with great flexibility. It is possible to create zero-entry floors, ideal for children and families, progressive-depth areas, deeper zones for specific attractions, slide landing pools or configurations designed for events and special activities.

Modularity also makes it possible to divide aquatic spaces into independent areas, including through the integration of movable elements or dedicated technical solutions. This allows a water park to evolve over time, adapting its offer to different seasons, target groups and management needs.

Another design element is the possibility of integrating acrylic panels, which can be used to create transparent walls, visual effects and highly distinctive architectural solutions. In this way, the pool becomes an integral part of the visitor experience, not only a functional element of the park.

A modern water park needs to offer different experiences for different users: children, families, teenagers, adults, groups and guests looking for relaxation. Modular technology makes it possible to design pools and attractions with specific configurations, while maintaining a consistent and controlled construction logic.

Variable-depth lagoons

Lagoons are among the most versatile attractions in a water park. They can be designed with zero-entry floors, progressive depths and areas dedicated to young children, families and light activities.

The modular system makes it possible to define floor levels, water access routes and functional zones with precision. This supports safer and more intuitive use, especially for children and for users who prefer gradual access to the water.

From an operational point of view, modularity makes it possible to create large and articulated surfaces while maintaining an orderly, inspectable structure that is easier to manage over time.

Wave pools

Wave pools require a pool structure capable of withstanding continuous dynamic stress. Wave generation technology produces repeated water movement, with variable loads on the structure and internal pool surfaces.

In this context, a modular stainless steel system offers mechanical stability and construction precision. The pool can be designed to accommodate the equipment required for wave generation, while meeting requirements for safety, flow distribution and maintenance.

For an investor, this means being able to integrate one of the most recognisable attractions in a water park within a structure designed to withstand intensive use.

Artificial rivers with slow or fast flow

Artificial rivers, whether designed with a slow flow or a more dynamic current, are attractions built around continuity of experience. Users do not experience the pool as a static space, but as an aquatic route.

Modular technology makes it possible to design curves, variable sections and controlled depths, adapting the route to the characteristics of the park. The prefabrication of panels helps maintain precision in the geometry and consistency in surface quality, even in complex configurations.

From a maintenance perspective, working with modular components makes it easier to inspect the different sections and supports more organised long-term management of the facility.

Splash zones and splash parks

Splash zones and splash parks are increasingly common in water parks, especially for family audiences. These are low-depth or no-standing-water areas integrated with water games, sprays, interactive elements and children’s routes.

A modular system allows these areas to be integrated into the overall project, maintaining continuity between pools, surfaces and systems. The design can include play zones, circulation areas and spaces that allow parents to maintain visual contact, with careful attention to safety and ease of management.

Modularity is also useful when a park wants to expand or update its offer over time, introducing new attractions without completely rethinking the original structure.

Slide landing pools and arrival zones

Slide landing pools are essential technical elements. They must be correctly sized according to the type of slide, the speed of entry into the water, the required depth and the flow of users.

Modular technology makes it possible to create dedicated pools, with geometries and depths designed according to the attraction. This helps combine safety, operational efficiency and architectural integration with the rest of the water park.

In addition, the quality of the internal pool surface and the stability of the structure are particularly important in areas exposed to continuous and repeated use. A well-designed modular pool can simplify maintenance and support the operational continuity of the attraction.

The construction of a water park is a complex operation. It involves designers, general contractors, specialised suppliers, technical system providers and operators. In this context, time is a critical economic variable.

A delay in delivery is not only a technical issue. It can mean missing an opening season, reducing expected revenue, delaying commercial campaigns that have already been planned and increasing the indirect costs of the project.

Modular swimming pool systems offer a concrete advantage because they reduce many of the uncertainties associated with traditional construction. Components arrive on site prefabricated, checked and ready for assembly. This makes installation faster, more predictable and less dependent on complex on-site processes.

Compared with a fully cast-in-place concrete construction, the modular system requires fewer wet works, reduces the need for multiple trades to operate at the same time and limits material waste. The impact of weather conditions can also be lower, because a significant part of the production process takes place before the components arrive on site.

For an investor, every week gained can have significant economic value. Opening a water park earlier, or meeting a strategic seasonal window, can directly affect the return on investment. Installation speed is therefore not only a technical advantage, but a factor of competitiveness.

Of course, timelines depend on the scale of the project, the complexity of the attractions, site conditions and coordination with the other operators involved. For this reason, planning should be defined from the earliest design stages, in collaboration with the Myrtha technical team.

The choice of construction technology for a swimming pool or water park should not be assessed only on initial cost. A pool is an infrastructure designed to operate for many years, often in conditions of intensive use and with high expectations from the public.

For this reason, it is more appropriate to consider the entire life cycle. How easy will it be to keep the pool efficient? How flexible will the facility be over time? How much will maintenance interventions affect the operational continuity of the park? How easy will it be to integrate new attractions or adapt spaces to future needs?

A modular stainless steel system is not necessarily the lowest-cost solution in the short term. However, it can offer a highly competitive cost-performance ratio over the full life cycle of the facility. The combination of industrial quality, installation speed, design freedom, material resistance and maintainability makes this technology particularly suitable for professional aquatic facilities.

For a water park, choosing a modular swimming pool means building an infrastructure capable of supporting the evolution of the project. Not only a pool, but a technical platform for creating aquatic experiences that are safe, attractive and manageable over time.
