Building a natural pool creates a beautiful backyard retreat that works with nature instead of against it. This guide walks you through each step of the process. Having a skilled pool builder can help ensure your project succeeds from planning to completion. You'll learn about layout design, excavation, plant selection, and ongoing care. These steps help you create an eco-friendly swimming space that looks amazing and stays healthy naturally.

Planning Your Natural Pool

Start by carefully planning your pool's layout for both looks and function. Think about the shape and size that fits your yard and complements your landscape. Decide where to put features like rocks, waterfalls, or plants to create a natural look. Plan for proper filtration and water circulation systems to keep water clean. Consider different depths for various activities while following safety rules. Good planning helps you create a peaceful swimming area that looks great and works well for years to come.

Excavation and Shaping the Pool

Begin creating your pool by digging and shaping the area according to your design. Mark the pool outline using stakes and string as guides. Use a shovel or excavator to dig out the space, keeping depths even throughout carefully. Shape the pool to match your plan, making smooth transitions between shallow and deep areas. Make sure pool walls have the right slope for stability. Remove all rocks, roots, and debris to create a clean base. Check measurements often to match your original plan. Once digging and shaping are done, you're ready for the next step.

Installing the Regeneration Zone

Set up the regeneration zone next to your main swimming area for natural water cleaning. This zone keeps water quality balanced and healthy.

Choose the Location: Place the regeneration zone near the swimming area for good water flow
Lay a Geotextile Liner: Put the liner on the bottom and sides to stop soil from mixing with water
Add Gravel and Plants: Use gravel for filtering and plant water plants for natural cleaning
Create a Slope: Build a gentle slope between the pool and the regeneration zone for better water movement

Setting up this zone properly is key to having a natural pool that takes care of itself.

Choosing the Right Aquatic Plants

Pick the right water plants to keep your pool clean and help with natural filtering. Use different plants like water lilies, iris, and rushes that look good and do important jobs. Floating plants such as water hyacinth provide shade and reduce algae growth. Underwater plants like hornwort add oxygen and give shelter to water life. Edge plants like cattails soak up extra nutrients and help keep water clear. Think about how each plant grows and what care it needs to create a balanced system. Mix different plant types for a healthy, thriving natural pool.

Adding Rocks and Natural Elements

Use rocks and natural features to enhance the appearance and functionality of your pool. Here are helpful tips for this step:

Placement: Put rocks around the pool edge and in the water to look natural and help beneficial creatures
Size and Shape: Choose different-sized rocks to add visual interest and create various water depths
Water Features: Add natural elements like waterfalls or bubbling rocks for soothing sounds and movement
Safety Measures: Make sure rocks are secure to prevent accidents, especially with children or pets around

Maintaining Water Quality

Keep your natural pool water clean and safe with regular care. Test pH levels weekly with a testing kit - levels should be between 7.2 and 7.6 for optimal swimming conditions. Use a pool skimmer to remove leaves and insects for clear water. Add water plants like lilies to help filter water naturally. Clean pool walls and floor regularly to stop algae growth. Use a pool vacuum or brush to remove buildup. Run your filter system daily and watch for any problems. Regular care keeps your natural pool crystal clear and ready for swimming.
