What is a shell pool?
A shell pool is a buried pool with a structure prefabricated in a factory. The basin is molded in one piece from reinforced fiberglass polyester or acrylic, and then delivered as a single piece to your site. This shell is then installed in an excavation prepared for this purpose, and connected to technical equipment (filtration, water treatment, etc.).
This is an ideal solution for individuals who want a quality pool with a reduced installation time and an attractive quality/price ratio.

Cost of a fiberglass pool in Belgium
The price of an in-ground fiberglass pool depends on the chosen model, its dimensions, the type of shell (polyester or acrylic), the equipment (heating, treatment, cover), as well as the exterior finishes.
Here is a estimate of the average prices in Belgium:
| Work item | Price range in Belgium (VAT included) |
| Polyester or acrylic shell (delivery included) | €10,000 to €20,000 |
| Excavation and site preparation | €3,500 to €6,000 |

The advantages of a shell pool
The buried shell pool has many benefits that explain its success:
- Quick installation: setup possible in a few days
- Structural strength: resistance to deformation and weather
- Perfect waterproofing thanks to a monobloc construction
- Simplified maintenance: smooth walls, less algae growth
- Modern aesthetics: wide choice of shapes, colors, and finishes
- Controlled cost compared to a masonry pool
- Comfort of use: soft coating, integrated stairs, relaxation benches
Available shapes and dimensions
Shell pools come in many predefined shapes, allowing them to adapt to your garden's layout:
- Rectangular: modern and suitable for swimming
- Ovoid or bean-shaped: for a natural and fluid style
- Compact: ideal for small urban plots
- With integrated stairs, benches, submerged beaches
Some shells also include relaxation areas (spa stairs, seating), perfect for combining pleasure and relaxation.
Maintenance of a shell pool
The shell benefits from a smooth non-porous surface, which limits algae growth and reduces the need for products. Maintenance includes:
- pH analysis and correction
- Cleaning the bottom and walls
- Winterizing at the end of the season
- Periodic equipment checks
The simplicity of maintenance makes it an ideal solution for individuals wishing to enjoy their pool without excessive constraints.

Frequently Asked Questions – Shell Pool in Belgium
How long does it take to install a shell pool?
One of the biggest advantages of the shell pool is its speed of installation. Generally, you should expect 7 to 10 working days from the start of excavation to filling the pool, excluding external landscaping. This makes it an ideal solution for individuals wanting a functional pool in record time.
What is the lifespan of a shell pool?
A well-installed polyester or acrylic shell pool can last 20 to 30 years or more, provided it is well maintained. The monobloc structure is very durable, and only the surface gelcoat (the interior coating) may require a repair or polishing after about fifteen years depending on usage.
Is a shell pool compatible with all types of terrain?
In most cases, yes. However, very clayey, sloped, or high groundwater terrains require specific adaptations: drainage system, reinforced concrete slab, or draining backfill. Avenir Rénovations Belgium conducts a preliminary soil study to ensure a risk-free installation.
What is the average price of a shell pool in Belgium?
The price of an inground shell pool generally ranges between €20,000 and €40,000 including VAT, depending on the chosen model, dimensions, type of shell (polyester or acrylic), options (heating, counter-current swimming, roller cover), and finishes. We offer turnkey solutions with customized quotes.
Is a building permit required for a shell pool in Belgium?
Yes, in many cases. In Belgium, constructing an inground pool, even a prefabricated one, generally requires a planning declaration or even a planning permit, depending on the size of the pool, the location of the land, and municipal regulations. Avenir Rénovations Belgium assists you with all necessary administrative procedures.
Is a shell pool compatible with a roller cover or shelter?
Absolutely. Many models of shell pools are designed to integrate a submerged cover, a safety curtain, or a telescopic shelter. This enhances safety, maintains water temperature, and limits heat loss. These features can be planned from the project's design stage.
