Natural swimming pools, also known as natural swimming ponds, are gaining popularity for backyards. Swimming in clean, naturally filtered water is a delightful experience, especially as trends shift away from traditional blue pools due to health concerns over chemicals. The desire for these pools is increasing.
Joel Scott from Clear Water Revival states, 'Natural pools are quickly becoming the preferred choice for homeowners,' thanks to innovative filtration systems.
Research indicates that chlorine-free pools offer notable health advantages for swimmers and the environment. With rare exceptions, natural pools require only a single filling.
Considering the installation and upkeep of a natural swimming pool? Expertise is essential for pool landscaping, particularly for natural ponds. Here's what you should be aware of.
Steps to Create a Natural Swimming Pool

Building a natural swimming pool is best left to specialists. Generally, you'll need to excavate a flat-bottomed area about 6 feet deep, construct foundations and walls, and line it with a high-quality pond liner or use tanking. Ensure proper inlet and outlet pipes for filtration, and plan drainage to prevent rainwater flooding. Additionally, explore pool fence ideas for safety considerations.
Ideal Shapes for Natural Swimming Pools
A natural swimming pool should resemble a wild pond, avoiding straight lines and sharp angles. Unlike natural swimming pools, living swimming pools typically maintain traditional shapes but incorporate similar planting and filtration methods.
Size Recommendations for Natural Swimming Pools
Like conventional pools, natural swimming pools need adequate space to dive in comfortably. For swimming purposes, aim for at least 200 sq ft. Remember to account for safety fencing and pool deck ideas for accessibility, as well as planting for both filtration and aesthetics.
Location Considerations for Natural Swimming Pools
You can place a natural swimming pool in most areas of your backyard, but avoid low spots that collect rainwater. Some shade is beneficial, ideally around a quarter of the day. Consider pool shade ideas to enhance comfort for those using the pool.
Maintaining Cleanliness in Natural Swimming Pools
To keep the water clean, some systems filter it through gravel, while others utilize plants to absorb nutrients and pathogens. Shallow shelves with oxygenating plants can help purify the water. Certain setups employ beneficial bacteria to decompose organic materials, eliminating the need for chemical disinfectants, reducing energy consumption, and cutting maintenance by up to 50% compared to traditional pools.

Temperature Variations in Natural Swimming Pools
Water temperature in natural swimming pools varies with depth, similar to ponds and oceans. In shallower areas, expect temperatures around 80℉ on warm days.
Is Maintaining a Natural Swimming Pool Difficult?
For upkeep, a regeneration zone with local plants is necessary to filter the water effectively.
Typically, two pumps are required, which can be discreetly installed beneath a surrounding deck, negating the need for a separate pump house.
Installation Costs for Natural Swimming Pools
Installing a natural swimming pool starts at approximately $35 per sq ft, though costs may fluctuate based on site conditions and accessibility.
Cate Statham, a senior chartered building surveyor at Knight Frank, notes, 'The installation costs are comparable to conventional tiled pools.' Operating costs are minimal since natural pools don't need heating or coverings, primarily involving leaf management and organic debris prevention. Consider safety precautions, especially regarding fencing.
Do Natural Swimming Pools Have Odors?
With proper maintenance and filtration, natural swimming pool water remains odor-free, eliminating the unpleasant chlorine scent.
Can Fish Live in a Natural Swimming Pool?
Yes, fish can inhabit a natural swimming pool, aiding in water cleanliness. Consult professionals to determine the right types and quantities.
Do Natural Swimming Pools Attract Wildlife?
Natural swimming pools enhance your wildlife garden ideas, drawing various wildlife such as insects, birds, and larger creatures seeking water and shelter. Frogs and toads may thrive there, while mosquitoes will be less of an issue with moving water. Occasional snake visits can be managed by planting snake-repellent plants around the pool area.
