When it comes to pools, it is useful to know that there are two main types of construction: skimmer pools and overflow pools.

Many people have heard these terms but often do not know the real differences between the two options. For example, an overflow pool is often automatically associated with the famous infinity or panoramic pool, without realizing that there are different types of overflow, each with specific features and advantages.

Now we will examine the differences between a skimmer pool and an overflow pool, looking at how they work, their main benefits, and when it is best to choose one over the other, both for private use and for hospitality facilities.

 

Skimmer pool: classic and accessible

The skimmer pool represents the classic type, present in Italian gardens for decades. In this type of pool, the water stays a few centimeters below the edge, generally between 5 and 10 centimeters, and is drawn in through openings called skimmers along the walls. The filtered water is then returned to the pool through side jets, providing sufficient circulation to keep the water clean, although less uniform than in an overflow pool.

From an aesthetic point of view, the skimmer pool is functional but more traditional. The visible edge and waterline create a "step" between the water and the pool edge, which can appear less harmonious than an overflow pool. Cleaning the waterline requires regular manual maintenance, and frequent use may necessitate additional chemicals to maintain water clarity and hygiene. Liners and decorative bands can also fade over time, requiring periodic upkeep.

Despite these characteristics, a skimmer pool can be a sensible choice in certain situations. It is a more economical solution compared to an overflow pool and can be suitable when the budget does not allow for a larger investment. It can also be appropriate if the pool is used less frequently, such as in second homes or less-visited gardens, where aesthetics and visual impact are not the priority.

In summary, a skimmer pool remains a functional and established solution, suitable for those seeking practicality and lower costs, but it does not offer the same elegance, automatic cleaning, or visual impact as an overflow pool.

Example of a skimmer pool:

and the perimeter strip about 10 cm lower than the pool edge)

 

Overflow pool: design, efficiency, and prestige 

In an overflow pool, the water does not remain below the edge as in traditional skimmer pools. Instead, it reaches the edge and gently flows into a surrounding channel, creating a uniform circulation that keeps the water clear and pristine. This system not only improves water quality and cleanliness but also provides an unmatched visual effect: the water level reaches the edge, eliminating the unsightly "step" typical of skimmer pools and transforming the pool into a true mirror, reflecting the sky, garden, and surrounding architecture.

Thanks to this continuous circulation, maintenance is minimal: the water remains transparent and hygienic without constant manual cleaning, and the need for chemical products is greatly reduced, making the pool more sustainable and cost-effective over time. In overflow pools, there is no waterline to clean weekly, no liner discoloration under the edge, and no decorative bands to replace—common issues in skimmer pools. The edge stays clean and neat, and the pool deck becomes more spacious and harmonious, ideal for loungers, furniture, and relaxation.

The aesthetic impact is another major advantage: the water reaches the edge, providing elegance and harmony to any garden, transforming the space into a dreamlike environment. There are different types of overflow, each with unique characteristics. You can explore them on this page of our website.

Each type offers a different experience, but all ensure superior cleanliness, optimal water circulation, and unmatched aesthetics compared to skimmer pools. Imagine a perfectly linear water edge reflecting the sunset sky, your garden, and the surrounding architecture—this is the magic of an overflow pool.

where the water reaches the pool rim and flows discreetly beneath the edge)

 

Which one to choose?

If you are thinking of building a pool and want the best in terms of aesthetics, functionality, and prestige, an overflow pool is undoubtedly the best choice. With its water level reaching the edge, continuous circulation, and automatic cleaning, this type offers concrete advantages: the water stays clear and sparkling, the garden transforms into an elegant and harmonious space, and the entire property gains in value and prestige. In other words, you are not just building a pool—you are making a long-term investment that enhances both quality of life and the visual appeal of your property.

Despite its limitations, a skimmer pool can be a reasonable choice in certain situations. It is more affordable than an overflow pool, making it suitable when the budget is limited. It is also particularly well-suited for occasional use, such as in vacation homes or less frequently visited gardens, where aesthetics and visual impact are not a priority.

In summary, choosing an overflow pool means prioritizing design, comfort, and long-term value, while opting for a skimmer pool can be a pragmatic choice when functionality and cost containment are the main priorities.

 

Pools for hospitality facilities

In hospitality facilities, a pool is not just a recreational element: it is a showcase that can influence guests’ experiences and shape their perception of the property’s quality.

An overflow pool offers clear advantages in this context. Continuous and uniform circulation ensures the water remains clean and hygienic, even when the pool is used by many guests. The water-level edge eliminates unsightly steps or corners, creating a visually elegant and harmonious effect that enhances the sense of luxury and attention to detail. This translates into a superior guest experience and positive feedback, boosting the facility’s reputation.

A skimmer pool, on the other hand, has more noticeable limitations in a hospitality setting. The water stays below the edge, and circulation is less uniform, requiring more maintenance and frequent use of chemicals to maintain hygiene. In addition, the visible edge and waterline create a less harmonious visual effect. For a heavily frequented property or one targeting high-end clientele, this can reduce the visual impact and overall perception of prestige.

In summary, when it comes to hospitality facilities, the choice between skimmer and overflow depends on the objective: an overflow pool ensures a premium experience, simpler management, and higher aesthetic impact, while a skimmer pool may be adequate only for limited use or budget-conscious contexts, without enhancing the perceived value of the property.

What is the difference between a skimmer pool and an overflow pool?

The difference between a skimmer pool and an overflow pool mainly lies in the water circulation system and water level. In skimmer pools, the water remains about 5–10 cm below the edge and is drawn in through side openings along the walls. In contrast, in overflow pools, the water reaches the edge and flows into a channel, ensuring uniform circulation and a clearly superior aesthetic effect.

What are the advantages of an overflow pool compared to a skimmer pool?

The advantages of an overflow pool compared to a skimmer pool include consistently clear water, reduced maintenance, and less use of chemicals. An overflow pool also offers a more elegant aesthetic thanks to the water-level edge, making it ideal for those seeking superior design, prestige, and functionality, both in private settings and for hospitality facilities.

Quando conviene scegliere una piscina a skimmer?

A skimmer pool is a good choice when the budget is limited, pool use is occasional, or a functional solution is preferred without particular focus on design. The skimmer pool remains practical and reliable but requires more maintenance and does not provide the same aesthetic impact as an overflow pool.

Are overflow pools suitable for hospitality facilities?

Overflow pools are particularly well-suited for hospitality facilities such as hotels, resorts, and agritourisms. Thanks to continuous circulation, the water remains clean and uniform even with a high number of guests. Moreover, the elegant design and water-level edge enhance the property’s prestige and improve the overall guest experience.

ChatGPT ha detto: How much more does an overflow pool cost compared to a skimmer pool?

The cost of an overflow pool compared to a skimmer pool can be up to twice as high, depending on the size, type of overflow, and materials used. Despite the higher investment, an overflow pool offers long-term advantages in terms of aesthetics, reduced maintenance, and added property value.
