When thinking of an indoor swimming pool in a home, the image that comes to mind is instantly evocative and capable of making one daydream: well-being, relaxation, abandon, harmony of the senses. A true symbol of luxury and comfort in the modern home.

Sometimes it is a large, long pool, other times a mini indoor pool, a small and precious domestic jewel to enjoy fully throughout all seasons of the year.

The pool is not simply a tank full of water to spend a few hours of pleasant relaxation. It is a complex system, made up of numerous elements that must interact impeccably to ensure high performance, safety, and longevity. In this context, technology plays a crucial role.

Designing an indoor pool requires skills and experience significantly higher than those required for an outdoor pool.

Let’s take a closer look at the topic.

 

FACTORS TO CONSIDER WHEN 
DESIGNING AN INDOOR POOL

As already mentioned, when it comes to indoor pools, technology plays a central role. It’s not just about the materials or the position of the pool: the surrounding environment is also crucial.

Only by considering all these factors together can the water space inside the home fully express its potential.

 

The best location for an indoor pool

Determining the correct location for an indoor pool is not just a matter of convenience. It is a true building structure, involving significant structural loads and the presence of numerous systems.

It is essential to ensure that the supporting floors are adequate to bear the weight of the pool filled with water and the associated systems, whether the installation is on the ground floor, the lower part of the house, or on an upper floor or rooftop.

Dehumidification of the Pool Area

The presence of an indoor pool inevitably generates a high level of humidity. For this reason, it is essential to install a dehumidification system appropriate for the size of the pool, the volume of the room, and the intended use of the pool.

To determine the most suitable system, it is necessary to evaluate:

  • How the pool will be used;

  • The amount of water contained;

  • The dimensions of the pool room.

Based on these parameters, it is possible to choose the most effective dehumidification method.

 

Types of Dehumidification Systems

Room consoles: A simple and economical solution, suitable for small volumes, installed about two meters from the pool.

Built-in consoles: Installed in an adjacent room, they pass through the wall, keeping the surfaces of the pool room free.

Ductable consoles: Ideal for managing condensation on glass walls; installed in the technical room near the pool.

Air Recirculation: Air Handling Units (AHU)

Air Handling Units (AHU) are advanced systems that perform two essential functions: heating and dehumidifying the environment.

They ventilate and filter the air, maintaining constant temperature and humidity throughout the day and year, automatically and continuously.

These systems are large and expensive, which is why they are mainly recommended for large spaces.

 

Soundproofing the Environment

Heat pumps, filtration systems, and dehumidification units inevitably generate noise. In indoor pools, living areas (living rooms, bedrooms, etc.) are often adjacent to the pool area or technical room.

It is therefore essential to carefully address soundproofing, using appropriate technical solutions such as:

  • Anti-vibration supports;
  • Dedicated pedestals;
  • Silencers and sound-absorbing materials.

     

Heating the Water and the Environment

To ensure optimal comfort in an indoor pool, it is important to maintain the following parameters:

  • Water temperature: between 26°C and 30°C (higher for therapeutic or professional use).
  • Air temperature: between 26°C and 30°C, generally aligned with the water temperature.
  • Relative humidity: between 60% and 70% (below 60%: cold sensation when exiting the water; above 70%: excessive humidity, condensation, and risk of mold).

     

Heating Systems for Indoor Pools

Water heating is crucial to guarantee comfort and year-round use of an indoor pool. Depending on the system requirements and home characteristics, different solutions can be chosen:

  • Heat pump: efficient and energy-saving, ideal for continuous use.
     
  • Electric heater: suitable for small pools or quick supplementary heating.
     
  • Heat exchanger: uses the existing heating system, ensuring high performance.

     

An Indispensable Ally: Pool Cover

A pool cover is essential for reducing energy costs. It helps limit heat loss, contain humidity, and maintain stable water temperature.

When the pool is not in use, it is always advisable to cover the pool, choosing between simple solutions or motorized roller covers, particularly suitable for elegant and refined spaces.

 

Wellness Accessories

An indoor pool should be fully enjoyed. Wellness accessories are essential to transform it into a true space dedicated to relaxation:

Hydromassage jets, blowers, water blades, shower heads, and countercurrent swimming systems all help make the pool a genuine place of pleasure and rejuvenation.

Indoor Pool Lighting

Lighting is often underestimated, but it plays a key role. Whenever possible, it is ideal to take advantage of natural light through skylights and large windows.

Alternatively, artificial lighting can enhance the architecture and details of the pool, creating evocative and dramatic atmospheres. It is essential to use only waterproof lights to ensure safety and long-lasting performance.

Waterproofing the Indoor Pool

Waterproofing is one of the most delicate aspects of building an indoor pool. Unlike outdoor pools, the walls of an indoor pool are often in contact with other areas of the house.

Meticulous design and execution are essential to prevent leaks, structural damage, and future problems.

 

Home Automation and Smart Control

Home automation for indoor pools is increasingly in demand. It allows all the main functions to be programmed and controlled in advance, making the pool ready for use at any time.

Via smartphone, tablet, or computer, it is possible to manage:

  • Water heating;
  • Filtration;
  • Lighting;
  • Sterilization systems;
  • Heat pump and temperature.

     

Water Sterilization Systems

For indoor pools, chlorine-free sterilization systems are preferred, as chlorine fumes can be unpleasant in enclosed spaces. It is better to opt for alternative solutions that minimize or completely eliminate the use of chlorine.

What does it cost to build an indoor pool at home?

The cost of building an indoor pool varies depending on size, materials, systems, and accessories. On average, prices start from around 30,000–50,000 euros for small to medium pools, while larger and more technologically advanced projects can exceed 100,000 euros. It is also important to consider ongoing costs related to maintenance, heating, and dehumidification, which are essential for comfort and long-term performance.

What are the structural requirements for an indoor pool?

An indoor pool requires strong load-bearing structures capable of supporting the weight of the water and technical systems. Floor load capacity must be carefully evaluated, especially when the pool is located on upper levels or rooftops. Proper insulation, waterproofing, and access to technical areas are also essential to ensure safety, durability, and ease of maintenance.

How are humidity and temperature controlled in an indoor pool?

Maintaining correct humidity and temperature levels is essential for comfort and structural protection. This is achieved through dedicated dehumidification systems and, in larger spaces, air handling units. Water temperature is typically kept between 26 and 30°C, air temperature aligned with the water, and relative humidity between 60% and 70% to prevent condensation, heat loss, and mold formation.

What are the most efficient heating and dehumidification systems for an indoor pool?

The most efficient heating solutions for indoor pools include heat pumps, heat exchangers connected to existing heating systems, and electric heaters for smaller pools or supplementary use. For dehumidification, ducted units and air handling systems offer the highest performance, especially in large environments, ensuring stable conditions, energy efficiency, and long-term comfort.
