A home swimming pool is no longer a privilege of the few but is becoming an increasingly common feature of modern living environments. Although often associated with luxury, its function goes much further – it represents an investment in quality of life, health, and the long-term value of the property. However, the path from the idea to the first dive is long and demanding, as it requires well-thought-out planning, knowledge of legislation and technical execution, as well as proper maintenance after construction is completed.
The first step is always a precise consideration of what we actually want from the pool. Will it be intended for family relaxation, sports swimming, or as an aesthetic addition to the outdoor space? This determines both its size and depth. Location plays a crucial role – ideally, the pool should be placed on the sunny side of the garden, and it is recommended that it be close enough to the house to allow easy access. At this stage, one must also become familiar with the legal aspects, since the construction of an in-ground pool generally requires a building permit and, in some cases, compliance with the municipality’s spatial planning regulations.
Once the basic questions are clarified, the next step is deciding on the type of pool. The market offers a wide variety of options – from more affordable prefabricated pools, which can be set up in just a few days, to in-ground concrete pools that require more extensive construction work but allow full customization to the owner’s wishes and freedom of design – from dimensions to shapes and features such as waterfalls or massage jets. Somewhere in between are semi-in-ground pools and polyester shells, which combine quick installation with satisfactory durability. Each choice comes with its own advantages and limitations, so it is best for the investor to decide based on real needs and financial capabilities.
Building Permit for a Pool in Slovenia
The legal framework depends on the pool’s volume (m³) and partly on its depth. According to the Regulation on the Classification of Structures, pools are classified into categories that determine the obligations regarding permits and notifications:
- – Up to 60 m³: the pool is considered a simple structure. No building permit is required, and there is no need to notify the start of construction.
- – Up to 100 m³, with a depth not exceeding 4 m: the pool is considered a less demanding structure. A building permit for a less demanding structure and notification of the start of construction are required; however, no occupancy permit is needed after completion.
- – Larger than the above criteria: the pool is classified as a moderately demanding or demanding structure; a building permit, notification of the start of construction, and an occupancy permit upon completion are required.
For classification purposes, open swimming pools are usually categorized under CC-SI 24122 (other civil engineering structures for sports, recreation, and leisure). If the pool is covered/enclosed as a building, it is classified as CC-SI 12650 (sports buildings), while it can also be added as an auxiliary structure to a single-family house under CC-SI 11100 (single-family residential building).
Planning
The most complex process is the construction of an in-ground concrete home pool, which begins with excavation and site preparation. Ground stability is crucial for long service life, so additional drainage or soil reinforcement may sometimes be required. Next comes the installation of reinforcement and formwork, which form the pool’s framework, followed by precise concreting, where watertightness is essential. Since concrete structures are porous, waterproofing is also mandatory. Only then comes the installation of systems – from filtration to electrical wiring and water heating systems. The pool’s final appearance depends on the choice of finishing, ranging from simple liners to luxurious mosaics, which give the space a completely individual character.
Modern home pools are becoming increasingly technologically advanced. Simple pools with basic filtration systems are rare, as users increasingly opt for advanced solutions. Automated systems now allow precise control of water quality, lighting, and temperature directly from a smartphone. Filtration has developed from classic sand filters to diatomaceous filters, which provide significantly cleaner water. Disinfection methods have also modernized – traditional chlorine is being replaced by saltwater chlorinators or UV lamps, which are gentler on the skin and the environment. For heating, investors most often choose heat pumps, considered the most energy-efficient solution, while solar systems that use renewable energy sources are also gaining popularity.
However, building the pool is only the beginning. To keep the water clean and pleasant to use, regular maintenance is required. This includes cleaning surfaces, removing leaves and debris, and ensuring proper chemical balance. Too high a pH or incorrect disinfectant levels can quickly cause problems, so it is recommended that owners test the water at least once a week and adjust as needed. Robotic cleaners are popular, as they significantly simplify maintenance and ensure perfectly clean pool floors and walls. In Slovenia, where winters are cold, proper protection during the off-season is also necessary. Correct winterization extends the lifespan of the structure and equipment while saving the owner from unexpected costs.
Natural Pools
In the past decade, natural pools, which are based on the principle of biological water purification, have gained increasing attention. Instead of chlorine and other chemicals, the water is purified by plants and microorganisms planted in separate filtration zones. Such pools resemble natural ponds, combining aesthetics with ecological awareness and offering a pleasant swimming experience without aggressive chemicals. Although the initial investment is often higher and they require more space, natural pools are increasingly attracting those who seek a sustainable solution and harmonious integration into the landscape.
The foundation of a natural pool is its division into two parts – the swimming area and the regeneration zone. The swimming area is intended for swimming and relaxation, while the regeneration zone is planted with aquatic plants that, with the help of microorganisms, purify the water. Water constantly circulates between the two areas: mechanical filters remove larger particles, while biological processes break down organic matter and prevent algae growth. The result is crystal-clear water without chlorine or other chemical additives that could irritate skin and eyes.
Of course, natural pools also have their specifics and limitations. They require somewhat more space than traditional ones, as the regeneration area with vegetation can take up as much or even more space than the swimming area itself. Proper functioning requires expert design, as plants and microorganisms must be carefully selected and balanced. The water in natural pools can also look somewhat different – often more natural in color compared to traditional pools, where the turquoise blue results from chemicals and liners.
When it comes to heating and extending the swimming season, natural pools are less adaptable, as heating can disrupt biological balance. However, during the warmer months, swimming in such water is an exceptional experience, as it offers direct contact with nature without artificial additives. In recent years, hybrid solutions have also been developed, where natural pools are supplemented with additional mechanical filters, providing even better water quality control.
The financial aspect of building a home pool should not be overlooked. In addition to the initial investment, which greatly depends on the type and size of the pool, annual maintenance costs must also be considered, usually ranging from a few hundred to several thousand euros. However, many owners ultimately agree that the value the pool adds to lifestyle and property more than justifies the investment. Market data shows that a well-built pool can increase a home’s value by five to fifteen percent, and even more in prestigious properties.
When we sum up all aspects – architectural, technical, aesthetic, and financial – it becomes clear that building a home swimming pool is by no means a simple decision. It is a project that requires long-term vision, precise planning, and professional execution. The reward, however, is a space that combines relaxation, health, and prestige. As life becomes increasingly fast-paced, a home pool can be that personal retreat that provides the owner and their family with the luxury of time for themselves – without leaving home.
