It’s just like wild swimming in your own back garden, in crystal clear chemical-free water, immersed in nature.

And because natural pools start from a 40m2 plunge pool up to swimming lake size, they're perfect for most outdoor spaces.

Designed to fit your lifestyle and blend into your garden, a natural pool can be formal, contemporary or naturalistic. The water's edge may be finished with a fringe of marginal plants or stone coping for a formal look. 

Crystal-clear, chemical-free water, always 

A natural pool has a swimming area and regeneration zones separated by low submerged walls. Beautiful water plants growing in the regeneration zones play a vital role in your pool’s biological filtration system, keeping the water balanced. Our natural pools are also fitted with world-renowned Biotop’s water balancing technology to keep the water crystal clear and hygienically filtered.  


What are the benefits of a natural pool?

Easy, low-level maintenance with a pool robot thanks to the concrete construction and tailored liner.

The swimming zone and regeneration areas are separated by low submerged walls leaving you plenty of space to enjoy clear, hygienic, living water without the need for chemicals.

The water appears effortlessly natural by a carefully planned hydraulic system hard at work below the surface circulating the water through biological and mineral filters, ensuring it’s hygienic and fit for swimming all year round.

The result is a balanced pool, with water that feels like a mountain lake close to its source: soft, sparkling and with an energy that’s both rejuvenating and relaxing. And just like your garden, natural pools change with the seasons, giving you a still, reflective surface in winter which is where they get their name, sky mirrors.

What maintenance is involved with a natural pool?

Customer maintenance

Low-level maintenance is needed during the swimming season, and it's made easy with a pool robot. The skimmer needs checking and emptying daily, taking just a few minutes. In autumn, leaves need removing using a net.

Professional servicing

Cost: around £800 per pool service plus travel

Each winter our pool maintenance team services your natural pool, cuts back the water plants, cleans and vacuums the pool and services the pumps and filters. We check flow rates, flanges and hydraulics and we test and analyse your pool's water to ensure it's balanced.

Once every 4-5 years your pool requires a full service. The regeneration areas are thoroughly cleaned, ensuring your pool remains in good health with crystal-clear water.

During the swimming season we offer a consultation visit to assess pool plant growth and establishment.

In-pool Features

From experience, we appreciate how the smaller details can have a big impact on making the most of your pool. Boulders, jetties, stepping stones, play beaches and more add to your experience in the water.

With carefully considered pool hydraulics, you can enjoy a still, reflective pool for peace and tranquillity. We can create mesmerising ripples spreading across the water's surface or make it livelier with water bubbling up through boulders, or splashing into the pool via a millstone or rill. 

Optimising natural thermal gain means you can use your pool for more months of the year, and with lighting, you can enjoy it after dark.

A natural pool offers much more than swimming. Whether you’re looking for family fun, alfresco dining, quiet contemplation or a place to reconnect with nature, a hidden getaway in a hammock or a sundeck with loungers – our expertise doesn’t stop at the water’s edge.

Our pool design and landscaping teams incorporate sun decks, outdoor kitchens, outdoor living spaces and saunas, all surrounded by beautiful planting, integrating your natural pool into your garden.

Your pool will become the focus of family life and a retreat….just as ours has.

Aquatic and Ecological Planting

Water plants are key to hydro-botanical (chemical-free) filtration. Our understanding of the different aquatic species, their function and where and how they grow best in your pool means your pool will thrive. Read More...

And by adopting a naturalistic planting style in and around the water’s edge, your pool will be a magnet for wildlife and blend seamlessly into your garden.
