Discover the beauty of custom swimming pool conversions

Swimming Pool Conversions

Converting an unused or outdated swimming pool into a natural swimming pond is a sustainable, low-maintenance solution that adds beauty and biodiversity to any garden or outdoor space. At Turtle Swimming Ponds, we specialise in professional swimming pool conversions across the UK. Whether it’s a residential garden pool or a commercial leisure facility, we turn tired spaces into thriving, chemical-free aquatic environments.

Why Convert Your Swimming Pool?

Traditional pools often fall into disuse due to high maintenance costs, chemical treatments and ongoing energy consumption. A natural swimming pond offers a modern, eco-friendly alternative that brings your outdoor space back to life. Using EPDM pond liners and expertly designed planted regeneration zones, we create a balanced ecosystem that looks stunning and works with nature.

Many clients choose a conversion to reduce their environmental impact, save on energy bills and enjoy the calming presence of a natural body of water. The result is a visually striking, wildlife-friendly pond that functions as a safe and inviting place to swim. It’s also an ideal solution for those searching for an eco-friendly alternative to chlorine pools.

Our Swimming Pool Conversion Process

Initial Consultation & Site Assessment

Every conversion begins with a site visit to assess the current pool structure, access, surrounding landscape, and technical requirements. We discuss your goals for the project and advise on the best design options to meet your needs.

Drainage, Excavation & Reshaping

Once the design is agreed, we drain the existing pool and begin reshaping or adapting the structure as needed. This may include creating sloped zones for planting, removing hard landscaping, or repurposing existing materials to support your goal to repurpose an old swimming pool for wildlife and natural aesthetics.

EPDM Liner Installation & Filtration Zones

We use Firestone EPDM liners for durability, flexibility, and a lifetime lifespan. These are carefully installed and shaped to fit the converted space. Each job is bespoke. A planted regeneration zone is created to naturally filter and clean the water without the use of chemicals or mechanical filtration.

Planting & Naturalisation

We introduce oxygenating and marginal plants, helping to establish a self-sustaining ecosystem that supports clean, swimmable water and encourages wildlife. The planting scheme is designed to be low maintenance while adding texture and beauty.

Finishing Touches & Handover

Paths, decks, natural stone features or seating areas may be added as part of the final landscaping. We provide detailed guidance on pond care and seasonal maintenance. Your new natural swimming pond will be ready to enjoy for years to come.
