An in-ground pool is a permanent pool that is beautifully integrated into your garden and remains part of your outdoor space for years. Leisure Pools Benelux works with prefabricated polyester and fibreglass shells for anyone looking for a durable, neatly finished solution for a swimming pool in the garden, from a compact city garden to a spacious family garden. You receive tailored advice, guidance from model selection to installation, and a clear next step via the configurator, showroom or quote.
Why choose a polyester in-ground pool?
Anyone buying an in-ground pool is not choosing a temporary seasonal solution, but a lasting garden project. At Leisure Pools Benelux, the focus is on prefabricated shells in glass-fibre reinforced polyester: a permanent pool solution with a neat finish and comfortable everyday use. Such an in-ground pool can be integrated neatly into the terrace and garden design. At the same time, the chosen material also helps determine how smoothly installation proceeds, how manageable maintenance remains and how the pool holds up in the long term. That is why we look not only at the shell, but at the entire project in your garden.
Which in-ground pool suits your garden?
The right choice depends less on a standard size and more on how you want to use the pool.
- Available space: it is not only length and width that count, but also circulation space, the terrace, access for installation and room for the technical equipment.
- Use: relaxing, playing with the family or active swimming requires a different shape, depth and layout.
- Garden context: smaller or urban gardens also offer opportunities, provided the positioning is considered carefully.
- Terrain: level differences, orientation, soil and drainage are assessed in advance before we recommend a model or layout.
Build it yourself or have your in-ground pool installed?
Build it yourself
Have your in-ground pool installed
You arrange the excavation, foundation, drainage, technical installation and finishing yourself.
You get a process tailored to your garden, model and chosen specification.
The biggest challenge often lies in accurate measurements, planning and coordinating all stages on site.
Technical advice helps limit mistakes in preparation, connections and timing.
More personal control, but also more responsibility and a higher risk of remedial work.
More certainty about execution, planning and the intended end result.
How your in-ground pool is installed
The installation of an in-ground pool involves a chain of decisions that must fit together technically.
- 1. Advice and model selection: we start with your wishes regarding size, shape, depth, use and finish. This leads to a model choice that suits your garden and budget range.
- 2. Garden assessment: we then look at accessibility for delivery and installation, ground conditions, level differences, drainage and the space for the technical installation.
- 3. Site preparation: positioning, excavation, drainage and foundation must be properly coordinated. Working accurately and level here is crucial for the rest of the project.
- 4. Delivery and installation of the shell: the prefabricated shell is delivered at the right time and positioned exactly. This step must match the preparatory works and the available space around the pool when installing the pool.
- 5. Technical connections: pipework, filtration, pump and built-in components are not considered separately, but planned as an integrated whole based on the chosen pool model and its use.
- 6. Finishing and start-up: the pool edge, the terrace or the connection to the garden also help determine how sleek the final result looks. After start-up, you receive practical guidance for use and maintenance.
Which technical setup and finishing options do you choose?
- Basic setup: a complete technical installation includes, among other things, filtration, pump, pipework and the built-in components needed for safe and comfortable use.
- Comfort options: lighting, steps or an entry solution, a cover or roller shutter, and extra swimming comfort are recommended when they suit the chosen model.
- Location of the technical equipment: the location of the installation is important for accessibility, maintenance and neat integration into the garden.
- Always tailored: the exact equipment depends on dimensions, use, garden layout and the chosen quote.
What determines the price of an in-ground pool?
Component
Impact on the budget
Pool shell
Model, dimensions and specification determine the basis of the investment.
Site preparation
Accessibility, groundworks, drainage and foundation strongly influence the installation cost.
Technical setup and finishing
Pump, filtration, connections, electrical provisions and the finishing around the pool determine the total project cost.
Maintenance and use after completion
After completion, proper pool use is all about routine: keeping the water moving, monitoring filtration, cleaning and checking water quality. Throughout the season, attention shifts from daily use to winterising and later restarting. Because no two projects are identical, you receive practical maintenance advice tailored to your pool and technical setup.
Frequently asked questions about in-ground pools
Just before requesting a quote, a few practical questions usually still come up. These are the most important ones.
What does an in-ground pool cost including installation?
Online guide prices rarely provide a useful picture. The price of a swimming pool depends on dimensions, the chosen shell, accessibility of the garden, groundworks, foundation, technical setup, transport, connections and finishing. "Including installation" can therefore include more or less, depending on the agreed scope. If you really want to know what to expect, a tailored quote is the quickest route.
How large can a swimming pool be without planning permission?
There is no universal size limit for that. Whether you need planning permission depends on your municipality, plot, the positioning in the garden and any associated works such as paving, retaining walls or a technical room. Have this assessment carried out before the design and site planning are final. Leisure Pools Benelux can help you prepare your project details clearly for that permit application.
Can an above-ground pool, steel-walled pool or DIY kit safely be put in the ground?
Not every above-ground pool, steel-walled pool or DIY kit is designed for permanent ground pressure and the moisture load of a true in-ground situation. Drainage, foundation and technical connections also play a role. Anyone who still wants to put such a pool in the ground or convert it runs a risk of structural problems, extra maintenance and uncertainty about lifespan or warranty. Therefore, always first have it checked what the chosen system is intended for according to the manufacturer and whether your site situation is technically suitable. Anyone looking for a lasting, neatly finished solution is usually better off choosing a prefabricated polyester in-ground shell that is designed for in-ground installation from the outset.
