Swimming pools are a staple of backyard luxury, but not all pools are created equal. Traditional chlorinated pools, while popular, often come with high maintenance costs, chemical exposure, and environmental concerns. For homeowners seeking a cleaner, greener, and more natural alternative, natural pools have emerged as a compelling option. But how much does it cost to build your own natural pool?
In this comprehensive guide, we’ll break down the typical costs involved, explore the factors that influence your investment, and review the long-term benefits of choosing a natural pool over a conventional one.
What is a Natural Pool?
A natural pool, also known as a natural swimming pool or a swimming pond, is a chemical-free swimming area that uses plants, gravel, and biological filtration systems to keep the water clean. These pools blend seamlessly into the landscape, mimicking the appearance of a tranquil pond while maintaining clear, healthy water.
Unlike traditional swimming pools, natural pools do not use chlorine or saltwater systems. Instead, they rely on aquatic plants and natural filtration methods such as skimmers, biological filters, and regeneration zones to purify the water. This eco-friendly approach not only avoids harsh chemicals but also supports biodiversity, making it a fantastic addition to any environmentally conscious household.
Understanding the Basic Costs
The cost of building a natural pool can vary widely depending on location, size, materials, and design complexity. On average, the investment ranges between $50,000 and $150,000, with some custom-built options exceeding $200,000.
To break it down:
- Small natural pools (up to 500 sq ft): $50,000–$75,000
- Average residential natural pools (500–1,000 sq ft): $75,000–$130,000
- Large or custom natural pools (over 1,000 sq ft): $130,000–$200,000+
These figures are estimates. Let’s explore the components that factor into your final cost.
1. Site Preparation and Excavation
Before construction begins, your land needs to be properly prepared. This includes clearing vegetation, grading the land, and excavating the area to create the pool basin. Site prep costs typically range from $5,000 to $20,000, depending on terrain complexity and accessibility.
If the ground is rocky or unstable, excavation costs may increase. In some cases, drainage solutions or soil stabilization must be addressed before digging begins, adding further to the expense.
2. Pool Construction
The actual construction of the pool involves forming the structure, installing liners or concrete, and shaping the pool basin. Some natural pools use a combination of rigid shell construction and softscape elements.
- Concrete or fiberglass pools: These are more durable but costlier to install. A concrete shell can range from $20,000 to $50,000.
- Flexible liners: Cheaper alternatives but may need replacement every 10–15 years.
Pro tip: For a more natural appearance, many builders use bentonite clay or rubber liners that replicate the look of a real pond while preventing water loss.
3. Filtration and Regeneration Zone
In a natural pool, a dedicated regeneration zone is essential for maintaining clean water. This area is filled with aquatic plants, gravel, sand, and biological filters to naturally purify the water.
Creating this system involves additional engineering and landscaping. Costs for the filtration system range from $10,000 to $30,000, especially if advanced pumps, skimmers, and underwater circulation systems are included.
4. Plants and Biodiversity Planning
The type of aquatic plants you choose plays a key role in the sustainability and aesthetics of your natural pool. Native species are often recommended to promote ecological balance and reduce maintenance.
- Basic plantings for small pools: $2,000–$5,000
- Custom aquatic landscaping: $5,000–$15,000
Some designers include fish such as koi or goldfish to further enhance the ecosystem, which may require additional planning and cost investment.
5. Additional Features
Like traditional pools, natural pools can include optional features that add to both enjoyment and expense. These might include:
- Waterfalls or natural rock formations: $5,000–$25,000
- Underwater lighting: $2,000–$6,000
- Pool heating systems (solar-powered preferred): $5,000–$15,000

While not mandatory, many homeowners find that these features enhance both functionality and aesthetic appeal.
Key Factors That Influence Cost
Building a natural pool is not a one-size-fits-all endeavor. Several factors will significantly impact the final cost.
1. Pool Size
Larger pools naturally require more materials, labor, and filtration capacity. If you’re planning for a backyard oasis or a larger family size, expect the cost of excavation, water movement systems, and planting zones to rise accordingly.
2. Location and Site Conditions
Location plays a crucial role:
- Remote or hard-to-access sites may incur higher labor and transportation costs
- Areas with high water tables might require drainage systems
- Climate type will affect heater requirements and seasonal usability
If you’re building in an urban property with limited space, custom engineering and space-efficient design will add to the cost.
3. Design Complexity
Simpler pools with gentle slopes and a modest regeneration zone will cost less than elaborate designs with lagoons, waterfalls, and natural rockscapes. The desired aesthetic directly influences the amount of customization required.
4. DIY vs. Professional Installation
While it’s technically possible to build a natural pool yourself and reduce overall costs, it’s a risky approach. The biological filtration system, circulation dynamics, and ecosystem balance require expertise. Most DIY attempts result in waterquality issues or higher long-term costs from failed components.
Hiring a professional with experience in natural pool design is recommended, even though it increases upfront expenses. However, it ensures a functional, healthy, long-lasting pool.
5. Local Regulations and Permits
Like any major property project, natural pool installation might require permits, especially if there are changes to water usage, land grading, or runoff management. Fees vary by region but can include:
- Permitting fees: $1,000–$5,000
- Environmental consultancy: $2,000+
Be sure to check with your local municipality before breaking ground.
Comparing Natural vs. Traditional Pool Costs
Curious how natural pools compare to their traditional counterparts?
Upfront Costs
On average, traditional in-ground pools cost $40,000 to $100,000 depending on size, materials, and added features. Saltwater systems add $2,500–$5,000 to the final bill, while chlorine pools may have slightly lower initial costs.
However, natural pools still fall within a similar price range — especially when factoring in higher-end models — making the cost difference less dramatic than many assume.
| Pools Type | Average Cost | Key Cost Drivers |
|---|---|---|
| Natural Pool | $50,000–$200,000 | Construction, biological filtration, aquatic plants, landscaping |
| Traditional Chlorine Pool | $40,000–$100,000 | Concrete or fiberglass structure, chemicals, plumbing, filtration, liners |
| Saltwater Pool | $50,000–$110,000 | Standard chlorinated pool cost + saltwater generator |
Long-term Maintenance
Where natural pools really shine is in long-term operation. Here’s a snapshot of annual maintenance costs:
- Natural Pool: $500–$2,500/year (mainly seasonal maintenance, plants, and system inspection)

The absence of chemical adjustments in natural pools translates to both lower expenses and less hands-on effort.
Environmental and Health Considerations
Traditional pools often pose environmental concerns due to chlorine runoff and high water usage. Natural pools, on the other hand, are self-sustaining ecosystems that contribute to biodiversity, support pollinators, and don’t use synthetic chemicals.
From a health standpoint, swimming in a chemical-free environment is gentler on the skin, eyes, and respiratory system, making natural pools a safer option for children, pets, and allergy-prone individuals.
How to Minimize Your Natural Pool Cost
Despite the significant investment, there are ways to make natural pool construction more affordable.
1. Simpler Designs
Opt for a minimalist design that avoids complex features like waterfalls, custom rock formations, or advanced lighting. A streamlined regeneration zone and fewer additional features can significantly lower your budget.
2. DIY for Non-Technical Elements
While you shouldn’t attempt building the filtration or circulation system yourself, you can help with minor landscaping, planting, or deck construction, especially if you have experience. Just ensure to consult with experts for the critical water systems.
3. Use Local Materials and Plants
Sourcing plants, rocks, and construction materials locally reduces transportation costs and ensures compatibility with your environment, lowering maintenance in the long run.
4. Plan During Off-Peak Seasons
Pool builders may offer discounts if you schedule your project during the fall or winter when demand is lower. Additionally, labor rates might be reduced, offering savings on construction timelines.
5. Budget for Seasonal Maintenance
While annual maintenance is lower than a traditional pool, you’ll still need to budget for plant trimming, water testing, and occasional cleaning. Planning these yearly costs into your original budget helps avoid financial surprises.

What factors influence the cost of building a natural pool?
Building a natural pool involves several cost-influencing factors, including the size and complexity of the design, the materials used, and the location of the pool on your property. Natural pools require specialized construction techniques to mimic the aesthetics and function of natural water bodies, which can increase labor costs in comparison to traditional pools.
Additionally, the need for a regeneration zone—a section of the pool where aquatic plants and microorganisms naturally filter the water—can affect the total footprint and design complexity. Site conditions such as soil type, topography, and local climate may also impact excavation and maintenance costs. Custom features like rock waterfalls, natural stone edging, or underwater benches further contribute to the overall investment.
How much can I expect to pay for a natural pool on average?
On average, the cost to build a natural pool ranges from $30,000 to $100,000 or more, depending on factors like design, size, and materials. Smaller, simpler designs using local materials and fewer custom features might fall closer to the lower end, while larger, custom-built natural pools with extensive plant zones and rocky landscapes typically reach the higher end of the price range.
This average also includes expenses such as excavation, waterproofing, filtration systems, planting zones, and any necessary permits. In comparison to a traditional chlorine pool, this cost can be slightly higher due to the additional engineering needed to establish a balanced aquatic ecosystem. However, these costs should also be balanced against the potential long-term savings in water and chemical usage, as natural pools typically demand fewer resources for ongoing maintenance.
Are there long-term cost savings with natural pools compared to traditional pools?
Yes, natural pools can offer significant long-term cost savings compared to traditional chlorinated pools. These savings come largely from lower chemical usage, as natural pools rely on plants and biological filtration systems to keep the water clean. There’s no need for chlorine, algaecides, or pH adjusters, which can add up to hundreds of dollars annually in a conventional pool.
In addition, maintenance tasks for natural pools are often less intensive and more about preserving ecological balance rather than constantly adjusting chemical levels. Energy consumption can also be lower if the system is designed to circulate water efficiently without relying heavily on pumps. Over time, these savings can offset some of the higher initial construction costs, especially for environmentally conscious homeowners seeking a sustainable recreational feature.
Do permits or regulatory fees add to the cost of building a natural pool?
Yes, permits and regulatory fees are an important consideration in the total cost of building a natural pool. Local zoning laws and building codes may classify natural pools as either ponds or pools and regulate aspects such as fencing, water safety, and placement on your property. These regulations can vary widely depending on your jurisdiction.
Permit fees themselves are generally modest, ranging from a few hundred to a couple thousand dollars, but meeting the requirements—such as installing new fencing, safety covers, or adhering to strict landscaping guidelines—can add more expensive costs. It is always advisable to consult with your local municipality or planning commission early in the planning process to understand what permits will be necessary and how they could influence both the design and budget of your natural pool project.
How does the design of a natural pool affect its overall cost?
Design plays a significant role in the total cost of building a natural pool. Customized shapes, natural aesthetics such as boulders and streams, and features like beach entries or swim-up grottos all contribute to higher construction expenses. Unlike the straightforward geometry of traditional concrete or vinyl pools, natural pool designs require more artistic input and labor to create an organic, visually immersive environment.
Furthermore, the design determines the surface area, depth, and regeneration zone size—elements that drive up excavation, liner costs, and planting requirements. If you choose to incorporate moving water elements like waterfalls or fountains, this also adds complexity to the plumbing and circulation system, increasing investment. It’s crucial to work with an experienced designer or contractor who specializes in natural pools to balance aesthetic goals with budget considerations.
Can I reduce the cost of building a natural pool by doing some of the work myself?
While it may be tempting to reduce costs by taking on some of the labor yourself, building a natural pool is a complex project that often requires professional skills. Tasks like excavation, lining installation, plumbing, and planting zone creation should be executed with precision to ensure a stable, self-sustaining ecosystem. Incorrect installation can lead to leaks, poor filtration, or ecological imbalances that may be expensive to repair later.
However, there are certain aspects that may be done DIY-style to cut costs, such as landscaping around the pool edge, sourcing materials locally, or maintaining the biofiltration zone once it is established. If you have experience in landscaping or construction, you might assist with lower-risk tasks under the guidance of a professional builder. Always ensure that your involvement doesn’t compromise the pool’s integrity or water quality, as that could incur much larger costs in the long run.
Are there additional equipment or maintenance costs for natural pools?
Natural pools generally require less chemical equipment than conventional pools but may incorporate pumps, biofilters, or UV sterilizers to support the water-cleansing process. These devices help circulate water through the regeneration zone and maintain clarity and health in the ecosystem. Some systems are designed to be energy-efficient, but the initial cost of these components must be factored into the build budget.
For ongoing maintenance, costs are usually lower but different in nature. You may need to replace or clean pumps, maintain plant health, and occasionally manage algae blooms or debris. Proper plant selection and regular upkeep can mitigate many issues, but there is a learning curve involved in managing the system’s biological balance. Annual maintenance costs are typically $500 to $2,000, depending on the complexity of the system and your local climate.
