Indoor swimming pool: what constraints, what cost of construction?

Being able to afford an indoor swimming pool is The must since it can be enjoyed at any time of the day and night, and in any season. It is therefore a profitable operation compared to a swimming pool in which you can only swim six or eight weeks a year at most. Be careful, however, to respect all the constraints that this implies so as not to have any worries afterwards. Building an indoor swimming pool also requires inquire well beforehand on the cost of construction because the budget to plan can turn out to be high.

Where to install your indoor pool?

All solutions are possible. For example, we can plan its construction at the same time as that of the house, transform a part of the house already built into a space dedicated to the indoor swimming pool, although this solution generally costs more because the work can be more complex. But you can also opt for an extension of the existing home, including the installation of a swimming pool. In either case, this type of arrangement increases the value of a property since the works were realized by a professional and therefore, in the rules of art.

Indoor swimming pool: the necessary constraints

You cannot install an indoor swimming pool without carefully thinking about your project several months in advance. In addition to administrative procedures essential, all the conditions must be met to ensure the sustainability of the work and allow users to evolve in a healthy and pleasant environment. Here are the main unavoidable constraints:

  • The demand for building permit compulsory for an extension greater than 20 m²: even before opening the site, it is compulsory to go to the town hall of your municipality to find out about the necessary obligations because this type of development generally involves a modification of the look of the house. It is therefore necessary to have the written agreement of the Town Planning Department and the mayor before starting the work under penalty of having to dismantle everything in case of refusal of the building permit.
  • A prior declaration of work is sufficient for an extension with an area of ​​less than 20 m² or if the swimming pool is to be installed in an existing building, provided that neither its volume nor its external appearance are modified.
  • The ceiling height : it must be sufficient for users to be able to move around the swimming pool while standing, but also because this allows better air circulation.
  • The ventilation : it must be ensured by a fairly powerful device, which does not dispense with equipping the room with windows and / or bay windows.
  • The dehumidifier : it is essential in this type of environment to preserve all materials because it avoids excess humidity responsible for mold (and allergies).
  • The system heater : an indoor swimming pool is very likely to be used almost every day. It is more economical then to opt for a heat pump.
  • Thethermal insulation of the room: it is essential to enjoy the pleasures of swimming in all seasons. It should help to maintain freshness in summer and heat in winter. Good thermal insulation maintains the temperature of the water, which avoids wasting energy. It is also essential to limit the risk of a sudden rise in water temperature and therefore the appearance of algae.
  • Thesoundproofing the local: it is also a crucial point to preserve the tranquility of the inhabitants of the house and that of the neighborhood. Walls, ceiling, electrical equipment, bay windows, patio doors and / or windows must be perfectly insulated.
  • The wall, floor and ceiling coverings : they must be compatible with an environment where the humidity is extreme.
  • The pool liner : we recommend tiling rather than liner because it is less resistant in an indoor pool than in an outdoor pool.

Indoor swimming pool: what is the cost of construction?

The costing of such a work can only be done on a case-by-case basis since it depends on different factors. The cost varies depending on whether the swimming pool is integrated into a house construction project or will be fitted out in an already existing house, or even requires the provision of an extension.

We must remember to take everything into account. The scope of the work as well as those necessary if one wishes to build a veranda for example, the fittings, the insulation, the type of swimming pool (in kit, free-standing, buried that is to say with shell or even concrete), the size of the pool of course, its shape, its depth, transport costs, accessories, the room’s dehumidification system and ventilation, but also the type of opening (XXL bay window or single door) are all points to consider for budget for an indoor pool. It is also necessary to take into account the difficulties of access to the site …

We recommend starting with use an indoor swimming pool comparator online and briefly describe their project in order to receive multiple quotes. But nothing can be decided without the professional having been able to come to his client to carry out an on-site study and study the feasibility of the project. He can then send the interested party a precise estimate depending on the constraints, the type of swimming pool desired and the level of sophistication of the facilities.

For information, building an indoor swimming pool generally costs more than installing a swimming pool in the garden. The minimum budget to be expected is around € 26,000, and at least € 50,000 for an indoor concrete swimming pool. But for a luxurious project including an extension of the house, extraordinary amenities and a custom-made shell pool, it can cost € 80,000 and even more.
