Natural Pool Conversions

Convert Your Existing Pool

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.

Depending on your site and preferences, this can mean a fully planted conversion with a wetland, a compact converter module that keeps your current pool look, or a hybrid approach that blends both. 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 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.

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. Fits tight sites.

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.

What Changes During a Conversion

A typical conversion includes:

• 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 (if choosing a regeneration zone)

What Stays the Same

• Your existing pool shell

• Your basic layout and footprint

• Most plumbing routes (modified as needed)

• Steps, benches, 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.

Conversion Costs

Typical conversion packages begin around €4,000 – €12,000, depending on:

• Pool size and depth

• Whether a wetland is added

• Equipment selection (pump, UV, biological chamber)

• Condition of existing plumbing

• Access and installation complexity
