Natural swimming pools are fast growing in popularity in the UK. From a number of perspectives, they offer something that almost all homeowners would want – the opportunity to swim outdoors in water that is free from chemicals like chlorine and does not damage the environment. At Compass Pools we have years of experience in providing high quality natural pools to properties across the country.
We utilise the most advanced forms of natural pool technology to eliminate many of the disadvantages traditionally associated with these types of pool. If you are interesting in having one installed at your home, please don’t hesitate to contact us today.
Natural swimming pools without harmful chemicals
One of the major advantages of a natural pool is that they do not use chemicals in order to keep the water clean. This has a number of benefits – firstly, there is no need to pay for the constant expense of buying chemicals, and additionally because the chemicals used to keep out bacteria can dry out your skin and sting your eyes, even when used in the correct amounts.
Using reed bed technology, our pools are not toxic to the plants around them. Having a natural pool not only means that you avoid coming into contact with harmful chemicals, it also looks fantastic in your garden.
Non-porous and free from bacteria
Traditionally swimming natural pools have a number of complications which make them challenging to build and maintain. Natural pools mimic a river or stream environment with a reed bed and a pump that keeps the water circulating so that the water is constantly refreshed. But in such a small body of water it is necessary to keep temperatures at 5oC or below to keep bacteria at bay – obviously this is much too cold for the majority of pool owners.
Most pools are built using concrete which is not really suitable for a natural pool as it is a porous environment that easily harbours bacteria. At Compass Pools we only use carbon ceramic composite which is entirely non-porous. This means that bacteria is kept out of your natural pool so it is safe to heat the pool to a more pleasant temperature.
How our eco-friendly pools work
One of the easiest ways for bacteria to enter a natural pool is through debris and vegetation falling in, so we have created a system that is able to overcome this issue. Using a combination of a reed bed and a filter, our O3 system adds oxygen molecules around the floor of the pool and jets them to cover its entire surface. This kills any bacteria that enters the pool by moving debris and dirt into the filter and preventing stagnant areas of water, which can harbour bacteria.
Our reed bed system is typically 25% of the surface area of the pool and is located below the main body so that dirt that hits the surface can be taken away by the filter system. Once through the reed bed, water passes through both a high-flow and a low-filter and then onto a contained light ray tube to kill off any remaining bacteria. Fresh water is then pumped back out.
Every natural pool that we sell comes with free monthly microbiological testing for two years so that you feel completely confident in the cleanliness of the water.

Frequently asked questions
There are three main reasons that homes and businesses choose to install a natural pool. Firstly, the absence of chemicals means that it’s better for the environment and less harmful to swimmers, promoting a healthier lifestyle that’s closer to nature.
Another factor is the low maintenance requirements of a natural pool. Owners won’t need to follow a strict routine of buying and mixing chemicals, monitoring a chemical filter or testing the pH levels on a frequent basis.
Finally, there’s the simple fact that natural pools are beautiful! Although conventional outdoor pools add a certain luxury to any property, the aesthetic appeal of a natural pool and regeneration zone can be just as striking; blending with the surrounding landscaping and becoming a striking garden feature.
As a rule, we recommend the regeneration zone is approximately the same size as the swimming area, however this can be slightly flexible depending on the pool design. This is something we would discuss with you in the early stages of planning.
No, you don’t need to worry about getting tangled up in plants while you swim. The regeneration area is kept entirely separate from the main pool, usually on a separate level or divided by a wall. You can even have the plant pool in a different area of the garden altogether and use pipes to move the water around.
The organic system of a natural pond relies on bio-diversity to keep the water clean, inviting everything from microscopic pond organisms to water beetles and larger animals like frogs. However, these creatures are attracted to the regeneration zone and will largely stay out of the main swimming area. Fish will not naturally appear in your pool; however, some pools can support a small number of fish in the swimming area (not the regeneration zone). Please discuss this with your pool designer if you are interested in this.
No. Mosquitos thrive where the water is still (or stagnant), deterring other forms of life that would naturally eat their larvae. In a natural swimming pool, the water is gently moving all the time, encouraging creatures that prevent a mosquito population from growing.
Just like a freshwater river or crystal-clear lake, natural swimming pools use a system of gravel, aquatic plants and natural biological processes to keep the water clean, clear and safe to swim in. The resulting water is often slightly darker than the artificially-tinted water of a conventional pool, but it should never be murky or stagnant.
Natural pools are self-cleaning, so once the proper pH balance has been reached, there is very little maintenance required. The pump will still need to be looked after so that it continues to pass water through the filter, and you may need to monitor plants and wildlife through the seasons.
The way a natural pool can seamlessly blend with its surroundings might give the impression that their installation is straightforward. However, the water has to be carefully tuned to the local climate and environment in order for the pool to regulate properly. At Compass Pools, we have many years’ experience in building natural pools that are beautiful and functional.
Most people find that natural swimming pools tend to be warmer than conventional pools. This is due to a combination of the shallow water in the regeneration area heating up faster in sunlight and dark liners absorbing and retaining more warmth. Installing a pool cover is a good way to boost this heat retention, too.
However, it is possible to heat the swimming area of your natural pool if you wish. Again, talk to our team if you would like more information about heating a natural pool, or head to our pool heating page.
Any swimming pool can pose a threat to a child if they are not properly supervised. Even with a natural pool, proper safety measures should be followed at all times. However, a natural pool is no more dangerous than a conventional swimming pool and, in fact, the lack of chemicals can be gentler on sensitive skin and eyes. Just make sure there are enough steps, ladders and shallow sections for children to safely exit the pool.
The guidelines around pets and natural pools are similar to those for pets and conventional pools. It’s perfectly safe for your dog to take a supervised dip in the pool, as long as it’s a breed that is a naturally competent swimmer and, just like with children, there is a safe way for them to exit.
One positive is that you won’t need to wash chemicals off of your pet’s fur when they leave the pool, although be aware that larger dogs and frequent use will introduce excess bacteria into the water that will take longer to filter out.
