There are three main types of swimming ponds, and choosing between them depends on your garden layout, aesthetic preference, and how you want the finished pond to feel. This guide covers the formal, walled, and hybrid styles, how they differ in design and construction, and what to think about when it comes to water quality, running costs, and year-round maintenance.
Different Types of Swimming Ponds
Choosing the right type of swimming pond depends on your aesthetic preference, garden layout, and ecological considerations. Each design offers a unique way to enjoy the benefits of a natural swimming pool.
1. Formal Swimming Ponds
Formal swimponds often emulate traditional garden layouts with their sleek, geometric lines. These ponds are designed to create a sense of elegance, making them an ideal choice for more structured garden spaces. These ponds frequently have clean, angular boundaries and upscale finishes like polished stone or granite.
- Design Elements: Formal ponds may include fountains or statues that serve as focal points, enhancing the structured beauty of the garden. They frequently have carefully chosen vegetation surrounding them that enhances the pond’s geometry.
- Shapes and Sizes: Typically rectangular or square, formal ponds can be customised to fit specific dimensions of a garden, often featuring straight edges aligned with existing property lines.
- Depth Considerations: Depths can vary, but they usually range from 1.2 to 2 metres, accommodating safe swimming conditions while maintaining enough volume for effective water purification.
- Ideal Settings: This type of pond suits traditional gardens. It is a perfect match for estates or homes where architecture is a focus.
2. Walled Swimming Ponds
Walled swimponds are defined by their use of vertical boundaries. These natural pools, which have walls enclosing them on one or more sides, offer a retreat that is ideal for private estates and urban gardens alike.
- Shapes and Sizes: Walled ponds can be adapted to nearly any shape—rectangular, circular, or even irregular forms.
- Depth Considerations: Similar to formal ponds, the depths of walled swim ponds generally stay within the range of 1.2 to 2 metres, designed for both safety and ecological balance.
- Materials: The walls are typically built with materials that echo the local architecture—think aged bricks, natural stones, or decorative blocks.
- Aesthetic and Practical Benefits: Besides their beauty, the walls of these ponds enhance the microclimate of the water, helping to keep it warmer.
3. Hybrid Swimming Ponds
Hybrid swimponds blend naturalistic and formal design elements, making them a good fit for gardens where a purely natural look doesn’t quite work but a conventional concrete pool would feel out of place. They cater to those who appreciate the organic feel of a natural pool but desire some structured elements.
- Shapes and Sizes: The flexibility of hybrid designs allows for a range of shapes, from circular to freeform, tailored to the unique contours of the garden space.
- Design Flexibility: These natural swimming pools might combine sleek stonework with rugged, natural edges or mix manicured plant zones with areas for wildlife. The result is a balanced ecosystem that is both beautiful and biologically functional.
- Depth Considerations: Hybrid ponds maintain a depth range suitable for swimming yet shallow enough to support aquatic plants and efficient water filtration.
Natural Swimming Ponds vs Concrete Pools
For many people the starting point is a straightforward question: why choose a natural swimming pond over a conventional concrete pool? Here’s how the two compare across the things that tend to matter most.
| Natural swimming pond | Concrete pool | |
| Water treatment | Chemical free, biological filtration | Chlorine and chemical treatment |
| Running costs | Significantly lower long term | Ongoing chemical and energy costs |
| Swimming season | Typically spring through autumn, with potential for year-round use depending on setup | Year-round with heating, but costly |
| Visual appeal | Integrates into the garden landscape, improves over time | Fixed structure, often covered out of season |
| Wildlife | Attracts birds, frogs, dragonflies, and other species | No wildlife benefit |
| Water quality feel | Soft, natural water, gentle on skin and eyes | Can cause irritation from chlorine |
| Maintenance focus | Ecosystem health, seasonal tasks | Chemical management, filter maintenance |
Running costs are one of the most significant differences. A natural swimming pond uses far less energy and requires no chemicals, which means the cost of ownership over several years is considerably lower than a concrete pool of equivalent size.
Water Quality and Maintenance
Maintaining your swimming pond’s water quality is key to ensuring a healthy environment. Through regular maintenance and the right equipment, you can prevent common issues such as algae growth. At Ponds by Michael Wheat, we offer pond maintenance packages to ensure your natural swimming pond is crystal clear.
Filtration and Water Circulation
Filtration systems are crucial for maintaining clear and healthy water. Your pond should have a mechanical filter to remove debris and a biological filter to break down nitrogen compounds.
Circulation pumps play a vital role in this process, as they oxygenate the water and facilitate the filtration process. It’s essential to choose a pump that’s appropriately sized for your pond’s volume to ensure efficient water movement.
When building our swimponds, we use the first-of-its-kind Michael Wheat System to ensure our ponds are the safest and cleanest possible.
Algae and Plant Management
Algae management is a significant part of pond maintenance. Algae growth can be reduced through the strategic use of aquatic plants, which compete for nutrients and block sunlight. Regular removal of fallen leaves and debris will also reduce excess nutrients that fuel algae spread. Additionally, ultraviolet (UV) clarifiers can be used to kill bacteria and algae.
Seasonal Care
Your pond’s maintenance needs change with the seasons. In spring, it’s necessary to clean out any waste that has accumulated and restart your filtration systems. During the summer, regular checks will keep algae at bay.
Autumn may require the removal of fallen leaves, and as winter approaches, some ponds may need a heater to prevent the surface from freezing completely. Remember, proper seasonal pond care can minimise maintenance costs in the long run.

Health and Safety Considerations
When you’re considering taking a dip in a swimming pond, your safety and health should always come first. Ensure you are well-informed about your swimming pond’s maintenance and water quality aspects to enjoy a safe swimming experience.
Listed below are key health and safety considerations:
- Water Quality: Regularly testing the pond water for harmful bacteria such as E. coli is vital. Be aware of the levels of other bacterial indicators that reflect water safety.
- Chemical Free Water: All swimming ponds built by Ponds by Michael Wheat use natural filtration rather than chlorine. The water is kept clean through biological processes, micro organisms, and aquatic plants rather than chemical treatment, which means it’s gentler on skin, eyes, and the surrounding ecosystem.
- Fencing: It’s important to have secure fencing around the pond if you have children or pets. This prevents accidental falls into the pond.
- Maintaining a Healthy Ecosystem: Consider the ecosystem within your pond. Balancing the plant life and aquatic organisms can contribute to the natural cleanliness and health of your swimming area.
- Sun Exposure: While sunbathing may be enjoyable, overexposure to heat can lead to sunburn or heatstroke. Always apply sun protection and keep hydrated.

Frequently Asked Questions
What’s the difference between the three types of swimming ponds?
The main differences are aesthetic and structural. Formal ponds have geometric shapes and structured finishes, suits gardens with a traditional or architectural style. Walled ponds use vertical boundaries to enclose the water, which can suit urban gardens or sites with limited space. Hybrid ponds blend natural and structured elements, making them the most flexible option for gardens that don’t fit neatly into either category. All three use natural filtration and are chemical free.
How does a natural swimming pond stay clean without chemicals?
Through a combination of biological filtration, micro organisms, aquatic plants, and water circulation. The regeneration zone, which typically occupies around half the pond’s total area, is where water plants and beneficial bacteria do the work of absorbing nutrients and keeping the water clear. The swimming zone stays clean as water passes through this system continuously. When it’s designed correctly, the result is crystal clear water without a drop of chlorine.
What are the running costs of a natural swimming pond compared to a concrete pool?
Running costs for a natural swimming pond are significantly lower over time. There are no chemicals to buy, and the energy requirements of the filtration system are modest compared to a conventional pool. The main ongoing costs are routine maintenance and occasional equipment checks. For a full breakdown, see our swimming pond costs page.
Which type of swimming pond is right for my garden?
It depends on the style of your garden, the space available, and what you want the pond to look and feel like. A formal pond suits structured, traditional gardens. A walled pond works well where privacy or space is a consideration. A hybrid pond offers the most flexibility and suits a wide range of garden styles. The best way to work out which fits your garden is to see one in person, which is exactly what our swim pond open days are designed for.
