Choosing the best outdoor pool, i.e. the one that best suits your needs, can seem like a complicated task. However, by keeping a few key factors in mind, you can find the model that best suits your needs. Here are some tips to help you choose the perfect pool for your backyard.

• Analyse your needs. First of all, carefully consider how and where you intend to use the pool. Consider the number of people who will use it regularly, the space available in your backyard and whether you prefer a temporary or permanent solution.
• Suitable surfaces: The surfaces on which they rest must also be suitable to meet the support requirements. First, choose a space with a flat, level surface to avoid damage to the pool structure. Unsuitable surfaces for installing a pool are muddy, sandy and gravelly, as they are unstable. As they are generally installed in backyards, it is important that there are no plants or weeds that could grow and puncture the structure and lining.
• The structure: These types of pools are designed to be as easy as possible to assemble and disassemble. They can have a supporting frame, i.e. small steel tubes that are fixed to the ground and support the outer tank, usually made of PVC, or they can be inflatable, i.e. with inflatable edges that allow the pool to support itself once filled with water.
• Dimensions: The choice of dimensions must first be assessed based on the available space. The dimensions are standard and fixed, ranging from 2x3 metres for the smallest models to 14x7 metres.
• Shape: Closely linked to size, the various shapes are also an important choice to consider depending on the space available.
• Filter pump: Filter pumps are important accessories for keeping the pool water clean and clear throughout the period of use.
• Included accessories: Check which accessories are included in the package. Having a pool complete with all the necessary accessories can save you time and money.
• Installation and support: Check whether the seller offers installation or after-sales support services. This can be particularly useful for more complex pools such as rigid pools or spas.
• Sustainability and materials: Consider the environmental impact of the materials used for the pool and choose more sustainable options if available.

Rigid pools and tubular pools have different distinctive features that determine their use and durability.

• Rigid pools: Made with rigid panels or galvanised steel walls, they guarantee great stability and resistance. They have a longer lifespan than tubular pools thanks to their sturdy materials. More expensive than tubular pools, they represent a long-term investment. They require periodic and specific maintenance to preserve the materials.
• Tubular pools: Made of a series of metal tubes that support the PVC lining, they are lighter and easier to assemble. They are suitable for seasonal or occasional use. Available in various sizes, they are suitable for both small and large spaces. They require less maintenance than rigid pools.

To install an above-ground swimming pool, it is essential to choose the right location and prepare the ground properly.

Ideal area:

• Sunny: The area should be exposed to the sun for most of the day, facilitating water heating.
• Wind protection: Choosing an area sheltered from the wind reduces water evaporation and maintains a constant temperature.
• Accessible: It must be easily accessible for maintenance and daily use.
• Away from trees: Avoid areas with trees to prevent leaves and debris from falling into the water.

Ground preparation:

• Levelled: The ground must be perfectly levelled to avoid uneven pressure on the pool structure.
• Stable: Ensure that the ground is compact and stable, avoiding areas with a risk of subsidence.
• Clean: Remove stones, roots and other objects that could damage the bottom of the pool.
• Protective base: Place a mat or protective base under the pool to prevent abrasions and damage.

Preparation procedures:

• Measurement: Measure the area accurately to ensure that the pool fits correctly.
• Levelling: Use sand or gravel to level the ground and create an even base.
• Compaction: Compact the ground to ensure a solid and stable base.

Maintaining an outdoor pool is essential to ensure clean and safe water for swimmers.

Assuming that maintenance for this category of pool is minimal, there are a few small precautions to follow for proper care and management:

• Firstly, always use certified chemicals for cleaning, then always ensure that the filtration system is working properly .
• At the end of the day, it is important to cover it with a cover and avoid installing it on attics or terraces.
• To keep the pool water clean, it is important to add chlorine regularly, check the pH level periodically, and clean the pool of leaves or insects using skimmers or pool cleaners.
• Run the purification system for at least six hours a day.

Rigid pools offer numerous advantages over inflatable pools, making them a popular choice for those seeking durability and stability.

• Durability: Rigid pools are built from materials such as galvanised steel panels or other solid materials that ensure long-term durability. These pools can last for many years without requiring frequent replacement or repair.
• Stability: Rigid pools offer a stable and secure structure that can withstand external stresses such as wind or intensive use. They maintain their original shape without the risk of deformation, unlike inflatable pools, which can collapse under pressure.
• Capacity and use: Usually available in larger sizes, ideal for large families or those who want more space to swim. They can accommodate several people at the same time without any problems of space or stability.
• Maintenance: Rigid surfaces are easier to clean than inflatable materials, which can be more difficult to keep free of debris and algae. Rigid pools often come with more effective filtration systems, helping to keep the water clean for longer.

Rigid outdoor pools are made from various materials that ensure strength and durability over time.

• Galvanised steel: Galvanised steel is treated to resist rust and corrosion, ensuring a long service life. Steel walls offer high stability and resistance to external stresses.
• Reinforced PVC panels: Reinforced PVC is used for the internal lining of rigid pools, offering flexibility and resistance to damage. PVC is easy to clean and maintain, making it ideal for use in swimming pools.
• Treated wood: Some rigid pools use treated wood for the external structure, offering a natural and attractive appearance. Treated wood is weatherproof and resistant to pests, ensuring long life.
• Aluminium: Aluminium is a lightweight but strong material used for some rigid pool structures. Similar to galvanised steel, aluminium is highly resistant to corrosion and weathering.
• Steel sheets: Steel sheets offer superior strength, suitable for large, high-use pools. They are often coated with protective paints to increase their resistance to corrosion.
• Fibreglass: Fibreglass is used in some rigid pools for its durability and resistance to chemicals. Lightweight and easy to shape, fibreglass facilitates pool installation.
• Combinations of materials: Some rigid pools combine different materials to maximise the advantages of each, such as steel structures with PVC or wood coatings.

The liner is a waterproof membrane used to line the inside of above-ground pools, ensuring watertightness and improving the aesthetics of the pool. In other words, the liner prevents water leakage, ensuring that the pool remains full and usable.

Common materials for liners:

• PVC (polyvinyl chloride): PVC is one of the most common materials for liners, thanks to its durability and resistance to chemicals. It adapts easily to the shape of the pool, ensuring uniform coverage. Available in various thicknesses (usually between 0.2 mm and 0.85 mm), with thicker ones offering greater strength and durability.
• Polyethylene: Polyethylene is a lightweight and resistant material, mainly used for inflatable and tubular pools. Easy to work with, it allows for quick installation and removal.
• EVA (Ethylene Vinyl Acetate): This material offers greater elasticity, making it resistant to deformation. It has a softer surface, improving comfort when using the pool.
• Polyurethane: High mechanical strength and abrasion resistance, ideal for pools that undergo intensive use. Good insulating properties that help maintain water temperature.

Choosing the right size for an above-ground backyars pool requires evaluating various factors, including available space, intended use and budget.

• Available space: Before purchasing, measure the available area in your garden or yard to ensure there is enough space not only for the pool but also for access and maintenance. Leave at least 1-2 metres of free space around the pool for easy access and safety.
• Intended use: Consider how many people will be using the pool at the same time. Larger pools are ideal for large families or those who enjoy entertaining friends. If you plan to use the pool for swimming, choose a pool that is at least 7-8 metres long. For recreational activities and games, a smaller pool may be sufficient.
• Depth: If there are small children, opt for a pool with a maximum depth of 1-1.2 metres. For adults and experienced swimmers, a depth of 1.5 metres or more may be more suitable.
• Pool shape: Depending on the space you have available and how you intend to use it, especially if you plan to swim in confined spaces or use it mainly for relaxation, choose between rectangular, round or oval pools.
• Budget: Larger and deeper pools tend to have a higher initial cost. Also consider the costs of maintenance, heating and water treatment, which increase with the size of the pool.

Above-ground pools are the only type that do not require municipal authorisation. This is true in theory, but in practice it depends on the type and composition of the kit chosen.

Semi-inground pools that are easy to dismantle and prefabricated pools, mainly made of fibreglass and attached to the property, also do not require any permits.

However, if the volume of the pool exceeds 20% of that of the main building, then it is mandatory to apply for a building permit. This is also true in cases where technical regulations consider appurtenant works as 'new construction works', perhaps due to the particular environmental value of the area.

In any case, it is always advisable to check with the relevant municipal offices to avoid unpleasant situations.

Cleaning a swimming pool is essential to keep the water clear and safe for swimmers. Here are the main steps for effective cleaning:

• Surface cleaning: Use a net to remove leaves, insects and other debris floating on the surface of the water. Do this daily to prevent dirt from accumulating.
• Brushing the walls: Use a pool brush to clean the walls and bottom of the pool, removing algae and dirt deposits. Brush the walls at least once a week to keep the surfaces clean.
• Suction on the bottom: Use a manual vacuum cleaner or a robot cleaner to perform suction on the bottom of the pool, removing sand, gravel and other debris. Perform suction on the bottom of the pool at least once a week or more often if necessary.
• Filtration system: Check and clean the pool filter regularly to ensure it is working properly. Backwash the sand filter at least once every two weeks to remove accumulated debris.
• Chemical balance: Use a kit to test the pH, chlorine and alkalinity levels of the water. The pH should be between 7.4 and 7.6, while the chlorine level should be between 1 and 3 ppm. Maintain alkalinity between 80 and 120 ppm to stabilise the pH. Add the necessary chemicals to maintain water balance, including chlorine, algaecides and pH correctors.
• Additional treatments: Perform a weekly shock treatment with high-concentration chlorine to eliminate resistant bacteria and algae. Use flocculants to aggregate suspended particles, facilitating their removal through the filter.
• Regular maintenance: Clean the skimmer and pump baskets to remove accumulated debris. Check that the pumps and circulation jets are working properly to ensure adequate water mixing.

The maintenance costs of a rigid pool can vary depending on several factors, including the size of the pool, the type of filtration system and the use of chemicals.

Initial cost of accessories:

• Filters: Purchase of sand, cartridge or diatom filters at varying prices.
• Pumps: Swimming pool pumps can cost between €100 and €500 or more, depending on their power and features.

Chemicals:

• Chlorine: Chlorine is essential for keeping the water disinfected, with an annual cost ranging from €100 to €300.
• pH regulators: Products to regulate the pH of the water, with costs ranging from €50 to €150 per year.
• Algaecides and flocculants: Products to prevent algae growth and improve water clarity, with annual costs of around €50-100.

Electricity:

The cost of electricity to run the pump and filtration system can vary from €200 to €500 per year, depending on usage and local rates.

Routine maintenance:

• Cleaning: Cleaning tools such as pool vacuum cleaners, nets and brushes with initial and periodic replacement costs.
• System check: Regular inspection and maintenance of the filtration system and pumps, with variable costs.

Seasonal maintenance:

• Winterisation: Products and covers to protect the pool during the winter, with costs ranging from €50 to €200.
