During the construction, the natural swimming pools cost as much as conventional swimming pools, but their maintenance and operation cost are considerably weaker. You can count between 400 and 500 € by square meter.

It’s also possible to reduce some cost in making by yourself a part of construction work. The true saving with the natural swimming pool is on the equipment, the space and storage of chemicals and the cost of the chemicals themselves. It will be noted that the biological swimming pools need only an annual visit (to carry about plants and to check the filters and the skimmers).
