We’ve helped countless homeowners transform their backyards into sustainable oases with DIY natural swimming pools. It’s not just about digging a hole and filling it with water—you’ll need to understand the balance between swimming and regeneration zones. The initial planning phase is actually where most folks go wrong. They rush in without considering drainage, circulation, or local regulations. But don’t worry, with the right approach, you can create a chemical-free swimming experience that’ll make your neighbors wonder how you did it.
Selecting the Perfect Location for Your Natural Pool
When choosing the perfect spot for your natural swimming pool, we’ve found that location really is everything.
You’ll want a level ground with good shade to prevent those pesky algae blooms that can overtake the water.
Don’t forget to check local regulations! Your dream pool needs to be the right distance from property lines—trust me, dealing with code violations is no fun.
Make sure you’ve got enough space for both the swimming area (about 45-50 square meters) and the plant zone where natural filtration happens.
Good drainage is essential too, and if you can position near a water source, well, you’ll thank yourself later!
Planning Your Pool Zones: Swimming vs. Regeneration Areas
Now that you’ve found the ideal spot for your natural pool, it’s time to blueprint the most important aspect of your design: the distinct swimming and regeneration zones.
We’ve learned that at least 50% of your pool’s surface should be dedicated to the regeneration area where aquatic plants work their filtration magic. For a successful build, a swimming zone of about 45-50 square meters pairs well with a 10-20 square meter regeneration area.
Keep the regeneration zone shallow—no deeper than 18 inches—for best plant growth.
And don’t forget, water circulation between zones is absolutely critical! We’ll use pumps and PVC tubing to maintain water quality throughout your beautiful natural swimming paradise.
Essential Tools and Materials Checklist
Three essential tool categories stand at the foundation of any successful natural pool build, and we’ve learned the hard way which ones you simply can’t do without.
When gathering materials needed, prioritize quality over cost—especially for your synthetic liner.
Here’s what you’ll definitely need:
- Excavation tools – an excavator saves countless hours of backbreaking labor
- Compaction equipment – a plate compactor guarantees your foundation won’t shift
- Water circulation system – PVC tubing, water pump and an aerator are non-negotiable
- Filtration area materials – aquatic plants, gravel, and testing kits maintain water quality
Always overestimate materials by 10-15%—you’ll thank us later!
Step-by-Step Excavation Process
With our tools and materials ready, the real work begins! The excavation process starts with finding a shady, level spot.
We’ll outline two holes – one for the main pool (about 45-50 square meters and 1-2 meters deep) and a separate plant zone (10-20 square meters, 1 meter deep).
Getting an excavator will save your back! Make sure the sides slope gradually – about 1 foot down for every 3 feet across.
The pool bottom should be flat for better water circulation.
Once dug, line the edges with rocks to secure the liner. Slowly fill the pool with water and monitor for leaks before adding any landscaping features.
Installing Effective Natural Filtration Systems
When you’re ready to bring your natural swimming pool to life, the filtration system becomes the beating heart of your entire project.
We’ve found that proper biological filtration is key to crystal-clear water without chemicals.
Let’s install the essentials:
- Position a water pump at the pool’s far end to circulate water through the plant zone.
- Bury PVC tubing at least 18″ deep to connect your pump to the biological filter area.
- Add an underwater aerator to boost oxygen levels (plants and beneficial microbes love this!).
- Mount skimmers with steel-mesh filter mats to catch debris before it sinks.
Waterproofing Options: Liners and Clay Techniques
The right waterproofing solution makes or breaks your natural swimming pool from day one.
We’ve found synthetic liners like EPDM are fantastic options at 25 cents to $1 per square foot. They’re flexible in cold weather and resist UV damage brilliantly.
Alternatively, bentonite clay works wonders at about 35 cents per square foot. You’ll need to pack down this clay thoroughly with a plate compactor or tractor—about 6 pounds per square foot does the trick.
Don’t forget to leave liner material between your swimming and plant zones!
Regular maintenance checks prevent leaks that could damage your pool’s delicate ecosystem. Trust us, proper waterproofing now saves headaches later.
Adding Gravel, Stone, and Access Features
Creating a solid foundation for your natural swimming pool isn’t just about waterproofing—you’ll need the right materials to support healthy water and easy access.
When adding gravel, stone, and access features to your natural pool, follow these key steps:
- Cover the bottom with 4-5 inches of clean gravel to filter the water naturally and create a home for beneficial bacteria.
- Line pool edges with rocks to hide the liner and prevent erosion.
- Build cobblestone steps or a cantilevered dock for safe entry and exit.
- Compact and reinforce the perimeter with soil and decorative edging.
We’ve found these elements make all the difference between a functional pool and one that truly feels natural.
Selecting and Placing Aquatic Plants for Water Purification
Natural aquatic plants aren’t just beautiful additions to your swimming pool—they’re the workhorses that’ll purify your water without chemicals.
We recommend you select native aquatic plants suited to your local climate for best results.
Position emergent plants in shallow zones (6-18 inches deep), covering about half your pool’s surface area.
Mix these with submergent species like hornwort that boost oxygenation and nutrient uptake while deterring algae.
Monitor water quality regularly with home test kits.
Remember to anchor plants securely with gravel—never use soil from contaminated areas, as this might introduce pathogenic bacteria.
Trust me, your natural pool will thank you!
Seasonal Maintenance and Ecosystem Balance
Once your aquatic plants are thriving, you’ll need to shift your focus toward maintaining your natural pool’s delicate ecosystem throughout the changing seasons.
We’ve found that consistent seasonal maintenance is absolutely essential for water quality and preventing unwanted algae growth.
Here’s what we recommend:
- Test water quality bi-weekly using simple test kits – keep an eye on phosphorus levels.
- Remove fallen leaves and plant debris in spring and fall to prevent decay.
- Maintain consistent water levels even during dry periods.
- Increase aeration during summer months when oxygen demand is highest.
