Square wooden pools

The Scots pine used in these structures is treated in an autoclave to Class IV, protecting the material against fungi, wood-boring insects, and continuous moisture without the need for annual protective varnishes.

To maintain the product's original appearance, we recommend:

• Apply a water-based wood stain or saturator once a year to prevent the natural gray discoloration caused by sunlight.
• Clean the surface with low-pressure water and soft brushes to remove dust and pollen.
• Inspect the perimeter in spring and check that the exterior drainage does not allow water to pool around the base.

Keeping the exterior wall clean ensures the installation stays in optimal condition for years to come.

A 225 x 225 cm square wooden pool fits easily in a 4 x 4 meter patio, provided the ground has the load-bearing capacity needed to support more than 2,300 kg of water.

An above-ground installation requires no excavation, but you must check that the existing base is completely level and flat. If the ground is uneven or irregular, you must pour a reinforced concrete slab at least 10 cm thick to distribute the weight and anchor the tongue-and-groove structure without putting it under stress.

To optimize water hygiene in compact volumes, you can supplement the system with the Star 300 sand filter with pump to ensure a continuous recirculation flow.

Yes, constructing a reinforced concrete slab is essential to ensure the pool's stability and prevent uneven ground settlement under hydrostatic pressure.

A medium-capacity square model holding 2.3 m³ exerts a point load of more than two tons on its footprint. Placing the pool directly on soil, grass, or compacted sand causes uneven settling over time, deforming the tongue-and-groove joints of the wooden boards and tearing the inner PVC liner.

The base recommended by the installation manuals should be at least 10 to 15 centimeters thick, reinforced with welded wire mesh, and leveled precisely with no steep slopes.

The choice between above-ground and buried installation depends on the budget available for construction work and the accessibility of the site.

If you choose to install it above ground, the process is quick and requires no perimeter excavation or retaining walls. However, if you decide to bury it or partially bury it, you must carry out a perimeter excavation lined with drainage-type dimpled polyethylene membrane and backfill the sides with filter gravel so that the damp soil does not press against the panels.

Both setups share the same support base, a concrete slab, but the above-ground option makes it easier to inspect the pipes, surface skimmer, and joints of the outer pool shell, while requiring less initial labor.

Standard-size square pools, such as those measuring 225 x 225 cm with a depth of 68 cm, operate efficiently with cartridge filters or small sand filter units with flow rates of 2 to 4 m³/h.

These systems ensure complete recirculation of the 2,300 liters of water in less than an hour and a half. The plumbing connections are made using flexible hoses attached to the return nozzle and the surface skimmer integrated into the boards.

To automate chemical disinfection without damaging the lining polymers, use dedicated accessories such as the Starpool 2.5 KG tablet chlorine dispenser., ensuring controlled, consistent dilution of the sanitizing product.

You don't need to dismantle the pool during winter, as the French Scots pine structure and metal fittings withstand frost and exposure to the elements when properly winterized.

To protect the pool without removing the installation, we recommend:

• Lower the water level below the skimmer and completely drain the pipes and pump so frost doesn't burst the plumbing.
• Add a winterizing chemical to keep the water free of algae and bacteria during the cold months.
• Install winterizing floats to absorb ice expansion and place a cover stretched over the top edge.

Following this procedure protects the interior PVC liner from mechanical stress and keeps the structure intact for the 2026 season.

The PVC liner in a square wooden pool is protected by placing a polyester geotextile protective mat between the concrete slab and the pool floor, together with a smooth finishing profile at the wall corners.

This floor felt acts as a physical barrier against small stones, rough concrete, or splinters in the wood. The inside corners also have wedge-shaped pieces that prevent the liner from being stretched at a right angle, dissipating the tension caused by the water pressure.

If an unexpected hole appears due to friction during the swimming season, you have quick solutions available, such as the Starpool liner repair kit, for sealing the material even underwater.
