Grand opening lead by Fluidra
Advert by Fluidra S.A.
Caldea, the largest thermal leisure centre in southern Europe, is celebrating its 30th anniversary. The New Caldea project includes updating the thermal areas, changing the décor of the restaurant areas, modifying the landscaping, introducing new attractions, and culminating in the opening of a new hotel in 2026. Fluidra is in charge of transforming the two iconic lagoons (indoor and outdoor) into a hybrid space between wellness and entertainment.
In this first phase, the company reopens its large central lagoon after a comprehensive refurbishment process that has given it a more minimalist and modern look that resembles a natural mountain lake. The new lagoon features new landscaped relaxation areas with matching furniture and local vegetation that provide a fresh and welcoming atmosphere. At night, it is transformed into a starry sky thanks to an innovative and energy efficient decorative lighting system.
Design is the thread that connects landscape, ecology, architecture, and art. For this reason, the relationship between nature and human creation blends harmony and beauty. The revitalisation of Caldea‘s spaces is based on establishing a fluid relationship between the user and the environment. Led by DATA Arquitectura, this architectural vision is achieved through the use of soft materials and textures, delicate shapes, harmonious colours, nature and, above all, water, which is the main focus of the project.

Positioning the complex as a benchmark in immersive aquatic spaces
Fluidra’s intervention, divided into different phases, combined the renovation of existing elements with the installation of new hydraulic, scenic and filtration systems.
The indoor central lagoon is the heart of the thermal centre and is designed to provide a family-oriented experience. The project includes the renovation of existing elements and new effects designed to create a spectacle and bring life to the interior of the lagoon.
In the initial phases, Fluidra renovated key hydraulic components of the lagoon basin, such as overflows, pipes, impulsion connections and bottom drains to improve the current installation and operation of the lagoon. On the other hand, the water effects have been expanded and improved, enhancing the flow and illumination. The whirligigs and swan necks have been polished, while the piano waterfall has been restored to maximize its ornamental effect. In addition, high-efficiency pumps have been introduced, optimizing the energy consumption of the entire system.
The incorporation of the new stage or dry-deck fountain within the interior lagoon consists of a platform, partially submerged, that allows for a variety of uses. It can function as a children‘s playground area and, also, be transformed into a stage for water, light and sound shows. The fountain integrates interactive effects with LED chromatic variations and a laminar flow that contributes to the feeling of magic and surprise. This proposal has been designed not only from a technical point of view, but also to broaden the scenic appeal of the centre to diverse audiences and generate a coherent and immersive aquatic narrative.
Outdoor lagoon to be more open
The concept of the outdoor lagoon is completely opposite to that of the interior space, opting for a more open space without so many water effects. The renovation of the outdoor lagoon includes hydromassage beds made of EPS with stainless steel nozzles and the renovation of the piping system with turbo-pumps and new siphons to guarantee stable operation.
More works to follow
The following phases will bring a higher level of spectacularity and leisure elements to the indoor lagoon. The project will be reinforced with the installation of the remaining show elements and hydromassage effects.
The aim is to enhance the spectacle with water jets and lighting. All the existing cups will also be refurbished, with new interiors and hydromassage effects to increase its capacity. This work will also include two new effects: perimeter waterfalls on two pools and a central foam spout, both intended to create a more complete experience inside the lagoon.

Immerse in the world of water
Another potential proposal involves the complex‘s lobby, which now welcomes visitors with a circular water curtain to anticipate the sensory experience that takes place inside. The idea is to include a shallow basin that will collect the water coming from the curtain and a new cascade to immerse the user in the world of water from the very first moment.
With this action, Fluidra has combined engineering, design and technology to offer Caldea a new visual and sensorial narrative focused on water: an exemplary intervention where technique is put at the service of the experience.
