FAQ (Frequently Asked Questions)

What is the construction cost of a natural swimming pond? The investment for building a fully customized, turnkey swimming pond generally starts at €50,000 for base-sized projects. This value reflects solid structural construction, premium waterproofing, landscape integration with natural boulders, and the installation of state-of-the-art biological filtration systems. The final quote always adapts to the scale of the project, the terrain’s characteristics, and the exclusive features chosen.

Can I build my own swimming pond? While a “do-it-yourself” approach might seem appealing, building a balanced aquatic ecosystem is complex and highly technical. It requires deep knowledge of structural engineering, hydraulics, and biology. To guarantee long-term crystal-clear water, prevent soil collapse, and ensure the ecosystem functions perfectly without the use of chemicals, relying on specialists is crucial. At Oásis Biosistema, we guarantee not only the design but the total durability and safety of your investment.

What is the difference in cost and maintenance compared to a traditional pool? The initial construction cost of a high-quality swimming pond falls into the same bracket (or slightly higher) as a premium traditional pool, due to the meticulous landscaping work and applied biological technology. However, in the long run, a natural pond becomes much more economical. By using biology instead of chlorine or salt, the need to constantly buy expensive chemicals is eliminated, the water doesn’t need to be replaced, and the system reaches a natural balance that drastically simplifies maintenance.
