What additional equipment is essential for the indoor pool?

The indoor pool is very different from its outdoor cousin. Additional parameters come into play. The success of this project requires knowledge of the issues related to a basin in a closed environment. Its design, its realization require more attention, reflection, must leave nothing to chance and improvisation has no real place. The work is long, and the financial aspect consequent.

What are the parameters to take into account for a successful indoor pool?

When we talk about an indoor swimming pool, we must take into account two natural elements, air and water, and four factors intimately linked to these elements: humidity, evaporation and condensation, without forgetting temperature.

The balance of the air/water elements
What are the parameters to take into account for a successful indoor pool?

When air and water come into contact, completely natural phenomena are created and develop: evaporation and condensation.

The temperature difference between the ambient air and the Pool water plays a major role. The more difference there is between these two elements, the more it promotes evaporation.

Due to the situation and the extreme conditions of the indoor pool, the phenomenon is accentuated and amplified. If nothing is put in place to limit, curb this humidity, the humidity will be higher and much higher than what is "acceptable". Unpleasant consequences will appear in the more or less long term.

Ideally, the temperature balance between the ambient air of the building and the water should be in a range between 26 and 28°C.

So what to do about condensation?

Ambient humidity, mist, condensation of the aquatic part are manifestations intimately linked to the temperature of the air and water.

Condensation is the fact that the humidity contained in ambient air, and there may be a large quantity of it in the pool room, changes from a gaseous state to a liquid state. Humidity permeates everything, seeping into every nook and cranny causing inconveniences such as the appearance of mold on the walls, water running down the windows and leaving traces, the deterioration of furniture...

Condensation control depends above all on hygrometry control.

What to do to protect the indoor pool from excessive humidity?

What to do to protect the indoor pool from excessive humidity?

Bathing all year round in its indoor pool is a luxury, a dream that everyone hopes for. It would be harmful to see this happiness thwarted by excessive humidity. It is essential to find the balance between the temperature of the air and that of the water and to implement an effective system to stem these phenomena from the design of the aquatic area. Efficient heating for the room, a heat pump for the water, a ventilation system combined with a dehumidifier are the keys to success.

High performance insulation

To avoid these condensation problems, insulation of the walls, ceiling, floor, double glazing, are more than helpful. They prevent heat loss. As a result, when the contact between the hot air in the bathroom and the cold air from outside occurs, the temperature contrast is less and limits condensation.

A similar air/water temperature

To enjoy the pool all year round, it is essential to provide a heating system for the building and for the pool. The swimming pool heat pump is the most popular device, often the most efficient and the most economical for heating water.

Fight against condensation

The dehumidifier is the essential equipment that must be installed in closed bathrooms. It must be adapted to the volume and to the general and particular conditions of the swimming pool. It is unavoidable. Combined with ventilation, it is the solution to fight and control condensation.

An additional way to limit condensation in the room of the indoor pool is to cover the pool when not in use, like a submerged shutter for example.

Similarly, it is preferable to use materials suitable for humid environments, the durability of objects, coverings, etc. depends on it.


In a few words, the control of hygrometry protects against all hassles, alterations, odors, molds, deterioration of the building or the decorations. This requires high-performance and appropriate quality equipment.



It is essential to know exactly what an indoor swimming pool is to know how to approach the design of the room of the indoor swimming pool without encountering unforeseen problems. Which pond structures for the indoor pool are possible? What waterproof coatings for the indoor pool exist? These are the answers you need to know to clearly define which equipment to preserve the space of the indoor swimming pool will be necessary. To make your choice of an indoor pool or not, finally find out what are the advantages and constraints of an indoor pool.
