Convert Your Existing Pool

The most affordable path
to natural swimming

Most concrete and lined pools can be re-engineered into natural systems using your existing shell and circulation as the foundation. Instead of demolishing the pool, we adapt it for low-energy, chemical-free operation by upgrading the filtration, hydraulics, and — where space allows — adding a planted regeneration zone.

The goal is the same in every case: clear, living water that feels like swimming in a natural spring, without rebuilding your entire pool.

Three approaches

Three ways to convert a traditional pool

A. Regeneration-Zone Conversion (Plant-Based)

Adds a planted wetland that provides full biological filtration. Ideal when space allows a 25–50% regeneration area. The most thorough conversion — your pool becomes a true natural swimming pool biologically and aesthetically.

B. Compact Module Conversion (Plant-Free or Low-Plant)

Keeps your pool's existing look while swapping the chemical system for a biological filter module + UV-C sterilisation. Fits tight sites where a wetland isn't possible. Dramatically reduces chemical use — in many cases to zero.

C. Hybrid Conversion

A smaller planted zone supported by a compact biofilter — excellent when clients want a natural aesthetic but lack space for a full wetland. Best of both approaches: natural character and reliable biological performance.

What changes — and what stays the same

What changes during a conversion

Removing or isolating the chlorine/salt system
Upgrading the pump to a high-efficiency, low-energy model
Installing a biological filter and/or wetland
Adding or redirecting circulation lines
Integrating returns and UV-C sterilisation
Updating the control system and fittings
Optional planting of aquatic species

What stays the same

Your existing pool shell
Your basic layout and footprint
Most plumbing routes (modified as needed)
Steps, benches and swim zones
Your deck or patio
Your general pool shape

This is why conversions are so cost-effective — they preserve your structure and transform the system.

Benefits of converting to a natural pool

Clear, healthy, chemical-free water
Softer feel on skin and eyes
Lower long-term energy and maintenance costs
No more chlorine handling or storage
Summer-ready with minimal upkeep
Works with existing pool footprints
Can be plant-based or plant-free depending on preference

Is your pool a good candidate?

Most concrete, liner and tiled pools convert well. Suitable candidates include:

Standard rectangular pools
Freeform pools
Saltwater systems
Chlorine pools
Pools with aging filtration systems
Pools with pump-room access

If the structure is sound, conversion is almost always possible. A consultation gives you a direct answer for your specific pool.

Conversion costs

Typical conversion packages begin around from €15,000, depending on:

• Pool size and depth
• Whether a wetland is added
• Equipment selection
• Condition of existing plumbing
• Access and installation complexity
