Shell pool or concrete pool: which one to choose?

Are you dreaming of a swimming pool in your garden, but you are hesitating between a shell pool and a concrete pool ? Don't panic, you are not alone in this dilemma.

Choosing the right type of pool can seem complex, as each option has advantages and disadvantages that vary depending on your needs, budget, and the characteristics of your property. Whether you are drawn to a one-piece pool , which is quick to install and maintain, or an in-ground concrete pool , which is more customizable and durable, it is essential to understand the differences between these two solutions before you take the plunge.

Together, let's take a look at the essential criteria to help you choose the swimming pool model that will make your outdoor space a true corner of paradise!

The shell pool: quick installation and controlled budget

A shell pool is a prefabricated pool, generally made of fiberglass or polyester . It is distinguished by its monobloc structure , that is to say that it is manufactured in one piece and delivered directly to the installation site.

This solution is highly appreciated for its ease of installation, which significantly reduces construction time.

The advantages of the shell pool

The main advantage of the shell pool is its speed of installation. Once the earthworks have been completed, the pool can be installed in just a few days. This speed minimizes the impact on your garden and allows you to enjoy your new swimming area more quickly.

But the speed of installation is not the only advantage of the shell pool : and for good reason, the price of this type of pool is generally more affordable than that of a concrete pool. Depending on the pool models chosen, the cost of a polyester shell pool , including installation, generally varies between €10,000 and €20,000. This price is particularly attractive for those looking for an economical solution without sacrificing quality!

Another significant advantage of the shell pool is its ease of maintenance. Thanks to its smooth surface and flat bottom, algae and debris have fewer surfaces to attach to, which reduces daily maintenance efforts. The fiberglass or polyester that makes up the structure of the pool is also naturally resistant to humidity and chemicals, which makes it easier to maintain.

The disadvantages of the shell pool

Although robust, the shell pool is not as resistant as the concrete pool to extreme conditions. If you live in a region exposed to significant temperature variations, strong winds, or repeated frost episodes, the structure of the shell pool could be put to the test. The tensions exerted by ground movements or temperature variations can, in the long term, cause cracks or deformations, although this remains relatively rare with good quality models.

Finally, although installing a shell pool is quick, it requires specific transportation and handling. The process of delivering the shell , which is made in one piece, can be complex and restrictive. Difficult access to the land or obstacles such as trees or overhead electrical cables can complicate this step. These logistical challenges must be taken into account before embarking on such a project.

The concrete swimming pool: unmatched durability and tailor-made customization

A concrete pool is a custom-made pool, usually made of shotcrete (gunite) or poured concrete . This type of pool is built directly on your land, allowing for total customization in terms of shape and dimensions. It is often preferred for its longevity and robustness.

The advantages of concrete swimming pools

One of the biggest advantages of concrete pools is their exceptional durability . With a sturdy pool structure, this type of pool can last for several decades. Due to the strength of concrete , it is able to withstand harsh weather and climate changes without fear of cracks or warping. This longevity makes it a profitable investment in the long run, especially if you plan to stay in the same house for many years.

Another advantage of the concrete pool : its customization possibilities. You can choose the shape, dimensions and finishes of your pool according to your tastes and the constraints of your land. Whether you opt for a rectangular pool, an L-shaped pool or a pool with a free design, concrete allows you to create a unique pool, perfectly adapted to your needs.

The disadvantages of concrete swimming pools

However, the concrete pool has some disadvantages. First of all, the price of an in-ground concrete pool is much higher than that of a shell pool. The total cost of a concrete pool can vary between €15,000 and €40,000, or even more, depending on the size and complexity of the pool. This price includes not only the concrete and materials, but also the labor time required for its construction, which can extend over several months.

In addition, installing a concrete pool is a longer and more complex process. Construction requires several steps: earthworks, installation of reinforcements, pouring of concrete, drying, and finally laying of the coating. This work can disrupt your garden for several weeks, which can be a disadvantage for those who want a quick project.

Maintenance can also be more of a hassle, as concrete surfacing can deteriorate over time and require repairs.

Which swimming pool to choose: shell or concrete?

1. Consider the budget

One of the first criteria for choosing between a shell or concrete pool is the price .

If you are looking for a quick and economical solution, the shell pool is probably the most suitable option. Its cost is lower and its installation is much faster.

On the other hand, if you are willing to invest more for a custom and durable pool , the concrete pool represents an excellent long-term choice.

2. Find out about the duration of the work and the installation time

Installation time is also a key factor in your decision. 

Do you want to enjoy your in-ground pool as soon as possible? The shell pool is the ideal solution. In just a few days, your pool is installed, ready for use. Conversely, the concrete pool requires several months of construction, due to the multiple steps involved in its installation.

3. Consider sustainability based on location

Are you wondering how long a shell pool lasts versus a concrete pool? As a general rule, a shell pool lasts 15 years, while a concrete pool can last at least 30 years. And with good reason.t's robust structure enables it to withstand many years of use and the harshest weather conditions. It also offers greater resistance to bad weather, making it an ideal choice for regions with extreme climatic conditions.

The shell pool , although durable, does not achieve the same level of resistance.

4. Assess your customization needs

If customization is a key criterion for you, a concrete pool will probably be more suitable. You can design a custom pool according to your preferences in terms of shape, dimensions and finishes.

The shell pool , for its part, offers fewer possibilities in terms of customization, with standard models, such as the mini-pool or the 8×4 shell pool .

5. Don’t forget the building permit

Another element to take into account is the obligation to obtain a building permit . If you opt for an inground concrete pool, it is often necessary to apply for one, especially if the pool exceeds a certain surface area. On the other hand, shell pools , when they are less than 10m2 , are not subject to complex administrative procedures.

As you will have understood, choosing a shell or concrete pool depends mainly on your priorities. If you are looking for a controlled budget, quick installation and an easy-to-maintain solution, a shell pool is probably the best choice. On the other hand, if you are looking for a custom-made, durable pool that can withstand bad weather, a concrete pool will be a wise investment in the long term.

Whatever your choice, it is essential to take into account your needs, your land and your constraints to make your swimming pool project a success .
