If you want to create a natural pool, you have to pay attention to many factors. Size, material, but also filters and maintenance costs must be taken into account. You can find out how the costs for a natural pool are made up here.
In a nutshell
- The cost of material and filter system covers a wide spectrum
- Natural pools can be divided into different categories
- Maintenance costs are primarily dependent on space and technology
What are natural pools?
A natural pool is a swimming pond that is not cleaned with the use of chemicals or UV light. Instead, there is a so-called regeneration zone, which keeps the water clean. The area of this zone is directly dependent on the technology, such as the filter system and the total water volume.
Advantages of natural pools
A swimming pond or pool is the dream of many garden owners. After all, what could be nicer in summer than to escape the heat in the cool water? However, creating a natural pool requires a lot of money, time and physical effort.
Nevertheless, natural pools have some advantages. For example:
- the water is chemical free
- Habitat for water dwellers is offered
- Maintenance costs can be kept low

sizes and categories
Natural pools can basically be divided into five categories.
features | costs | disadvantage | benefits | |
---|---|---|---|---|
category 1 | - this swimming pond works completely without technology - Area of at least 120 square meters - 60 percent regeneration area required | - about 70 to 200 euros per square meter at the time of laying - apart from water and occasional cleaning, no follow-up costs | - Algae and aquatic life are abundant - a significant proportion of the area is used for the regeneration zone - only possible on very large plots of land | - particularly natural look - low follow-up costs - low maintenance effort - Habitat and water source for several species |
category 2 | - at least 100 square meters in size - 50 percent regeneration zone - Pump that cleans at least five square meters per hour | - about 200 euros per square meter - Ongoing electricity costs for the operation of the pump | - comparatively large - Swimming pool relatively small due to regeneration area - Water can be slightly cloudy despite the filter | - low acquisition costs and electricity costs - simple technique good habitat for plants and animals |
category 3 | - at least 80 square meters in size - 40 percent is for regeneration area - Ground filter and other technology required - The transition between the swimming area and the regeneration zone is open | - Depending on the volume and technology, from around 300 to 500 euros per square meter - Ongoing electricity costs depending on the technology used and its running time | - costs more to buy and maintain - more technique required - Less potential habitat for aquatic plants and animals | - Also suitable for smaller properties - less area required for regeneration zone - clearer water than category 1 and 2 |
category 4 | - at least 60 square meters in size - 40 percent is in the regeneration zone - comparatively much technology - Water must be completely circulated daily | - about 1,500 euros for the purchase per square meter - Ongoing electricity costs for the technology | - expensive to set up through filter technology - fewer plants and animals - Electricity costs | - Well suited for frequent use - Comparatively clear water - also fits into smaller gardens |
category 5 | - no minimum size - Similar to conventional pool - a lot of technology | - you have to reckon with 1,500 euros per square meter - Ongoing electricity costs depending on the selected filters | - little aquatic life and aquatic plants - Expensive to buy and maintain | - very clear water - doesn't have to be big just - Variable size of the regeneration zone depending on the filter performance |
Tip: The less space there is, the more technology is required. Although this generates ongoing electricity costs, it means little effort in the long term.

cost factors
How high the price and the ongoing expenses for the pool are depends on various criteria. For example:
- selected materials for insulation and lining
- excavation volume
- disposal of the earth
- Filter system and other technology
- desired purity
- plant
- water
The effort involved in cleaning can also increase the ongoing follow-up costs.
area and excavation
The costs per square meter of your natural pool can amount to 200 to 2,500 euros. To put it simply: the larger the pool and the less technology is used, the lower the price per square meter. However, it must be noted that the water is then usually comparatively cloudy. Algae, floating aquatic plants and aquatic animals will also be found in the swimming area. While this can reduce installation costs, it means more maintenance and more frequent cleaning.
Tip: To save costs, the natural pool can be created yourself instead of having the construction done.

position
Expenditures for cleaning and care can also be reduced if the right location is chosen for the natural pool. It should meet the following requirements:
- sufficient distance to trees and bushes
- free paths around the pool
- ideally partially shaded pool

So we spent about 5000 euros. But we had the excavated earth, excavators and gravel almost free of charge. Then there was the planting and some wood. So all in all: maybe 6000 euros. But not everyone has such good conditions. We know a few people who spent 40,000+ euros on this. [… ] But expect to pay 10,000 euros yourself. We bought the pump (20,000 l) for 80 euros on ebay and set up the technology ourselves. […]

We have [… ] a bio-pool, costs around EUR 43,000, complete with a solar shower, technology, plants, stairs, spotlights, etc. One pool looks like a real pool, the second pool is separate from the first and has plants. There is no chemistry at all. So far, a biologist has checked the water quality twice, the result being drinking water quality. I am very pleased. […]

Regarding the costs, as a company I can say that a swimming pond for 7000-8000 € is quite feasible, it really depends on the demands that are made on the pond. Which does not necessarily mean that an expensive pond is a better pond.
Basically one can say:

-a lot of technology -> high costs (also in maintenance) -> less maintenance effort
-little technology -> lower costs -> more maintenance effort
The amount of maintenance required for a pond naturally depends heavily on the demands that are placed on the pond.
frequently asked Questions
How does the cleaning in the natural pool work?Depending on the materials selected and the respective type, size and position, it may be sufficient to use a landing net and a sludge vacuum cleaner once a year. The more technology is available, the more attention must be paid to cleaning the filter system and pipes. Information on this can be found in the manufacturer's operating instructions.
Why is landing net useful?Because flying leaves can hardly be avoided. However, this has a negative effect on the water quality. Other coarse dirt, such as twigs or even branches, must also be removed.
Why does the regeneration zone have to be so large?So that there is enough space for the roots of the plants and the aquatic life that contributes to the purification. If a filter is used and this has a high performance, the growth can be less and less space is required for regeneration.
