Open-Closed Pool Construction

For reinforced concrete pools, a typical timeline is about 30–60 days once permits are in place. Excavation and the concrete shell take longest; because of concrete curing, this stage alone can take two to three weeks. Size, ground conditions, weather and finish type change the timeline.

Design and measurement, excavation, rebar and formwork, concrete pouring and curing, waterproofing, finishing (ceramic, mosaic or membrane), filter and pump plumbing, and finally filling and chemical balancing.

Under Türkiye’s Planned Areas Zoning Regulation, open pools that meet the conditions are excluded from the floor area ratio. Being excluded does not mean no permission is needed; for the exact rule, consult your municipality’s zoning office or the project architect.

In Türkiye, the Ministry of Health regulation requires 26–28 °C for commercial pools. Private home pools fall outside this regulation, but the same range is a good starting point.

Regulation values for commercial pools in Türkiye: free chlorine 1–1.5 mg/L in indoor pools and 1–3 mg/L in outdoor pools; pH 6.5–7.8. International recommendations point to a pH of 7.2–7.8, where disinfection works efficiently and eye and skin irritation is reduced. Levels should be measured with a test kit before use.

Common methods are heat pumps, a heat exchanger connected to a boiler, solar collectors and electric heaters. Indoor pools also need the humidity removed from the room air, so pool heating is usually planned together with dehumidification and ventilation.

In a skimmer pool the water sits a few centimetres below the edge; skimmer openings in the wall draw surface water to the filter. In an overflow (deck-level) pool the water is level with the edge, spills into a grated perimeter channel and reaches the filter through a balance tank. Overflow systems clean the surface better and are common in hotels and residential complexes; the balance tank needs more space and budget.

One or more edges are built as a weir so the water flows into a lower catch channel; from the viewing point the water seems to meet the horizon. It needs a catch channel or tank, a separate pump circuit to return the water and, on sloping ground, a structural design. The open edge increases evaporation and running costs compared with a standard pool.

Size and depth, ground conditions and excavation access, overflow or skimmer system, finish type, filter and pump equipment, heating, lighting and automation set the price. A firm figure comes after a site survey, once size and materials are chosen.

Pool depth and safety distances are set according to the exit points of slides and play elements; water slides follow the EN 1069 standard. Because user numbers are high, filtration and disinfection capacity is sized larger than for a standard pool, and floors are finished with slip-resistant material.
