Living Pool

Crystal-clear, chemical-free water


Sarah Murch

Living pools look just like conventional pools. Yet you'll swim in pure, living water without chemicals.

Hidden, ultra-quiet Biotop filtration units purify and filter the water biologically, keeping it clean and clear without chlorine and other chemicals. During the swimming season a pool robot cleans the pool daily.

What are the benefits of a living pool?

Suitable for the smallest spaces to bigger areas with options from a plunge pool to a large swimming pool.

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 living pool?

Customer maintenance

Only low-level maintenance is needed during the swimming season, and it's made easy with a pool robot. In autumn, leaves need to be removed using a net.

Professional servicing

Cost: c. £800 per pool service plus travel

Each winter our pool maintenance team will service your living pool, clean and vacuum the pool and service the pumps and filters. We test and analyse your pool's water to ensure it's balanced.

Once every 4-5 years your pool requires a full service, where the pool is thoroughly cleaned, ensuring it remains in good health, with crystal clear water.
