Infinity pools: what are the key components?

Infinity pools are now one of the most appreciated solutions for those who want to combine aesthetics, functionality, and well-being. With their distinctive “mirror of water” effect, these pools offer a unique visual impact, creating harmony and continuity with the surrounding environment.

It is no coincidence that they are often chosen for luxury residences, hotels, resorts, and wellness facilities, but increasingly, even in private settings, people opt for an infinity pool to enhance their garden.
In this article, we will explore what makes them so special, how they work, which components are essential – with particular focus on pool grates, an indispensable element for safety and hygiene – and why they represent a lasting and valuable investment.

What infinity pools are and how they work

The term infinity pool refers to a type of pool where water constantly overflows from the edge, flowing into a perimeter channel that directs it to a collection and filtration system. Unlike skimmer pools, where the water is drawn in through openings located just below the surface, in infinity pools the circulation occurs evenly across the entire surface.

The aesthetic effect is unmistakable: the water appears as a single mirror that blends into the horizon, creating a sense of visual continuity and architectural refinement.

There are different configurations:

  • In-ground infinity pools: fully integrated into the ground, these are the most common and represent the ideal choice for those seeking a long-lasting scenic impact.
  • Semi-inground infinity pools: a suitable solution for particular terrains or natural slopes, allowing an elegant effect even without a completely in-ground installation.
  • Infinity pools with an overflow edge on one side: widely used in panoramic locations, they create the effect of a waterfall that merges into the landscape.
  • Hidden overflow pools: the edge disappears from view, making the continuity between pool and environment even more natural.

Key components of an infinity pool

To ensure optimal operation, an infinity pool requires a series of components that work together. Among the most important are:

The compensation tank: collects the water overflowing from the edge, keeping the main pool level constant.

The filtration and circulation system: essential to ensure clean, sanitized, and continuously moving water.

The collection channel: located along the pool perimeter, it directs water to the compensation tank.

The infinity pool grates: often underestimated but crucial, as they ensure safety and functionality.

These must be installed along the collection channel and have the task of: allowing excess water to pass through, preventing blockages; protecting the channel and avoiding accidental falls; offering a stable and safe walking surface.

Grates can be made from different materials, but those in technical plastic – such as the solutions offered by Nexus – combine strength, practicality, and durability. Plastic does not deteriorate in contact with water and chemicals; resists UV rays and temperature fluctuations; guarantees safe anti-slip surfaces; and can be easily customized in size and color to match the pool’s design.

In addition, Nexus grates, such as the TWIN grate, are made of two materials, with a polypropylene (PP) base and a thermoplastic elastomer (TPE) contact surface. This innovative combination makes them pleasant to the touch, safe for barefoot walking, and compliant with the strictest European regulations (DIN 51097 and EN 13451-1 certifications). Their total absence of protrusions and the fact that they do not splinter provide additional safety, making them ideal not only for private pools but also for wellness centers, spas, public pools, and sports facilities.

The range also includes aesthetic and functional variations, such as the TWIN SCACCO line, available in different sizes, straight or bendable versions, and even customizable with embossed logos. For those who prefer a natural and elegant touch, the TWIN TEAK option combines polypropylene with the strength and beauty of teak wood, creating a unique product in the infinity pool grate sector.

Advantages of infinity pools

Choosing an infinity pool means investing in a solution that offers numerous advantages, both aesthetically and functionally.

The first element that stands out is undoubtedly the “mirror of water” scenic effect: the pool appears to merge with the surrounding landscape, creating a unique and highly valuable visual impact. This makes them particularly appreciated in private villas, resorts, and panoramic settings.

Thanks to uniform circulation, the surface water is constantly renewed. This reduces the presence of impurities, dust, and debris, ensuring a higher level of hygiene compared to traditional skimmer pools.

The absence of protruding edges and the constant water level also provide a more natural and enjoyable swimming experience, while the presence of grates along the edge ensures stability and reduces the risk of slipping.

Finally, infinity pools can be built with different architectural solutions: natural stone, mosaic, wood, or modern materials. Even the grates contribute to the design, with variations able to adapt to any style.

Another strength of infinity pools is their versatility. They can be installed in various contexts, always offering maximum aesthetic and functional performance.

  • Private residences: those who want to turn their garden into an oasis of relaxation will find in the infinity pool a solution that enhances the entire home.
  • In-ground infinity pools: ideal for villas and prestigious homes, they integrate perfectly with the surrounding environment.
  • Semi-inground pools: excellent for hilly terrains or spaces with structural constraints, they are an elegant and functional compromise.
  • Hidden overflow pools: increasingly requested in modern and minimalist contexts, they create an even more refined visual continuity effect.
  • Hotels, resorts, and wellness centers: overflow pools are not only an aesthetic plus but also a competitive advantage, as they improve guest experience and enhance the image of luxury and quality of the facility.

In all these solutions, the quality of the components is crucial. Choosing certified grates and accessories, such as those made by Nexus, means ensuring efficiency, safety, and long-term durability.
