Why choose a natural swimming pool?
Choosing a natural swimming pool means opting for a healthier swim, simplified maintenance, an organic design, and autonomous operation. It is also a respectful approach to the local ecosystem and a sustainable investment for your outdoor space.
An ecological alternative without chemicals
The natural swimming pool operates without chlorine, bromine, or chemical treatments. It relies on a principle of biological filtration through plants and lagooning areas.
You enjoy pure and soft water, without skin or eye irritation.
A harmonious landscape integration
Unlike a traditional pool, the biological pool follows the shapes of the garden. It fits as a natural element of the decor and can resemble a body of water, pond, or lagoon.
Its aesthetics perfectly suit Swiss gardens and the varied topography of the land.
Reduced and automated maintenance
Thanks to a natural filtration system, the biological pool requires little maintenance. The plants ensure a large part of the basin's balance, and mechanical cleanings are limited.
The maintenance cost is also lower in the long term than that of a traditional pool.
A valuation of your property
In addition to providing added real estate value, the natural swimming pool reflects an environmental sensitivity increasingly sought after by buyers. It gives a unique charm to your garden and becomes a differentiating argument.
It is an investment that combines pleasure, sustainability, and elegance.
What are the steps of a natural pool project?
An ecological basin project is built in several phases, from site study to filling the pool. Our team follows a proven method to ensure an aesthetic, functional result that complies with Swiss standards.
What are the different types of natural pools?
There is not just one form of ecological pool, but several variations depending on the terrain configuration, budget, and owner preferences. We advise you on the type best suited to your project.
This type of basin includes a swimming area and a regeneration zone with filtering plants. Together, they form a complete ecosystem where the water is continuously filtered by gravity or circulation.
This is the most common model and the one that stays true to the 100% natural principle.
This hybrid version integrates a biological filter complemented by a pump and sometimes a sand filter. It allows for a more contemporary look, with straight lines and crystal-clear water.
It remains ecological while meeting certain usage or maintenance constraints.
It is possible to create a primarily decorative basin, but with water clean enough for occasional swimming. This type of project is suitable for small gardens or tighter budgets.
The priority is given to landscape integration.
How much do natural pool construction works cost in Switzerland?
The cost of a natural pool depends on its surface area, filtration system, type of coating, level of finish, and desired landscaping. Here is an indicative price table:
| Type of service | Price per m² (CHF) | Average total price (CHF) |
| Non-swimmable decorative basin | 500 – 800 CHF/m² | 8'000 – 15'000 CHF |
| Natural pool with integrated lagoon | 1'500 – 2'800 CHF/m² | 30'000 – 60'000 CHF |
| Hybrid biological pool (assisted filtration) | 2'000 – 3'500 CHF/m² | 35'000 – 80'000 CHF |
| Landscaping finishes (terrace, path, plants) | 300 – 600 CHF/m² | 5'000 – 20'000 CHF |
| Filtration system, pump, and regulation | Package 5'000 – 12'000 CHF | Depending on model |
These prices include labor, materials, design, equipment, and post-construction advice.
What equipment for a successful natural swimming pool?
The success of a natural swimming basin relies on the balance between the swimming area, the regeneration area, and the integrated technical equipment. These elements ensure water quality, safety, and comfort.
Planted regeneration area
This part of the basin hosts oxygenating, filtering, and decorative aquatic plants. Their role is to purify the water by absorbing nutrients and preventing algae proliferation.
It also provides shelter for beneficial insects in the ecosystem.
Skimmer, pump, and mechanical filter
A low-consumption pump can be integrated to improve water circulation between the different areas. A skimmer collects surface impurities such as dead leaves.
A sand or gravel filter can complement the system if necessary.
Natural liner or clay bottom
The interior lining can be made of phthalate-free liner, geomembrane, or even raw concrete depending on the desired finish. In some cases, clay is used as a natural waterproofing barrier.
These finishes directly influence the aesthetics and color of the water.
Vegetated or mineral beach
Around the basin, the beach can be landscaped with natural materials: wood, pebbles, stones, decorative gravel. It contributes to the landscape integration and functionality of the pool.
A pathway with stepping stones or a wooden terrace often completes the whole.
Which materials should be prioritized for a natural pool in Switzerland?
The materials used in the construction of a natural pool must meet requirements for durability, ecological compatibility, and aesthetics. They must also withstand the specific climatic conditions of Switzerland, particularly winter frosts.
Eco-friendly waterproofing
Phthalate-free PVC liners are a common choice for their waterproofing and durability. They are available in various colors to customize the appearance of the water.
Other solutions include EPDM membranes or natural clay coatings, which are widely used for semi-wild ponds.
Edging and beach in natural materials
To ensure harmonious integration into the garden, the beaches and surrounds of the pool can be made from untreated natural wood, limestone slabs, or pebbles.
These materials must be non-slip, draining, and frost-resistant to guarantee comfort and safety.
Filtering substrates and planted masses
The regeneration zone contains a specific substrate (gravel, pumice, sand) that plays a role in natural filtration. These materials ensure good development of filtering plants.
They must be selected to promote biological exchanges and limit algae proliferation.
Materials for terraces and pathways
To complement your pool, we integrate pathways made of local wood (larch, oak) or natural stone from the region. These elements contribute to the aesthetic coherence of the garden.
Particular care is taken to maintain visual continuity between the pool and other outdoor features.
Are there any aids for creating a natural pool in Switzerland?
As natural pools are environmentally friendly, they may, in some cases, benefit from local support or tax relief, particularly in relation to biodiversity or sustainable water management.
Cantonal or communal support for biodiversity
Some cantons encourage developments that promote nature in urban areas or gardens. Assistance may be available for plantings, natural ponds, or water recovery basins.
We will inform you of the programs in effect in your municipality.
Tax deductions based on the project's purpose
If the pool is part of a broader ecological enhancement or stormwater management initiative, it may in some cases be considered an investment that enhances the property value.
We will direct you to your fiduciary to estimate the tax impact.
Green loans and sustainable financing
Some banks offer preferential rate loans for ecological projects, including in the area of outdoor fit-out.
Our detailed quotes allow you to support any financing request.
What regulations govern the construction of natural swimming pools in Switzerland?
Like any outdoor construction, the realization of a natural swimming pool in Switzerland is governed by specific standards. These regulations vary by canton, but some principles remain constant.
Mandatory construction permit application
Every pool, even natural, must be subject to a permit application with your municipality. A file including a site plan, sections, a description of the filtration system, and environmental impact is required.
We assist you in the complete preparation of this administrative file.
Compliance with distance regulations to boundaries and buildings
Minimum distances must be respected between the pool and property boundaries, as well as with neighboring buildings. These rules vary according to the PLQ (Local Neighborhood Plans) and zoning regulations.
We integrate this data from the design phase.
Protection of water and soil
Natural pools must not pollute the soil or groundwater. The biological filtration system must be closed, and any discharge into the natural environment is prohibited.
Materials must be inert and certified in compliance with Swiss environmental standards.
Biotope or water body subject to special authorization
If your pool is classified as a landscaped water body, specific requirements regarding biodiversity or safety may apply. In some cases, an impact study may be required.
We verify in advance the category to which your project belongs.
FAQ – Construction of natural swimming pools in Switzerland
What is the difference between a natural pool and a traditional pool?
The natural pool operates without chemicals. It uses a biological filtration system through plants and a regeneration basin, while a traditional pool requires chlorine or bromine.
The result is also more landscaped and organic.
Can a natural pool be heated?
Yes. It is possible to integrate a heat pump or solar panels while preserving the biological balance. However, heating must remain moderate to avoid disturbing the ecosystem.
We adapt the solution to your needs.
Is the water really clean without chlorine?
Yes. The water is filtered mechanically and biologically through substrates and plants. The system is perfectly healthy if well designed, with clear and soft water.
We ensure monitoring of water quality post-construction.
Does a natural pool attract mosquitoes?
No, because the water is in constant motion, which prevents laying eggs and the development of larvae. The presence of dragonflies and other natural predators also helps regulate the ecosystem.
What is the time required for the work?
Depending on the size and complexity of the project, the work lasts on average between 4 and 8 weeks, excluding administrative delays. The development of the biological basin stabilizes completely in 2 to 3 months.
