Building an above ground pond can add beauty and serenity to any backyard landscape. However, installing a pond does require careful planning and consideration of costs. In this article, we’ll examine the key factors that influence the cost of constructing an above ground pond.

Size of the Pond
The overall size and depth of the pond are major determinants of the total project cost. A larger pond that holds more water and covers more surface area will naturally require more materials and labor to build. Here are some typical size ranges and estimated costs:
- Small pond (less than 100 sq ft): $500 – $1,500
- Medium pond (100 – 300 sq ft): $1,500 – $3,000
- Large pond (300 – 500 sq ft): $3,000 – $5,000
- Extra large pond (over 500 sq ft): $5,000+
In addition to the surface area, the depth and volume of water in the pond will influence the building expenses. Deeper ponds require more liner material, plus potentially additional waterproofing layers and preparatory excavation work.
Pond Liner
The pond liner is a critical component that prevents water leakage and contains the pond. Liner material is sold by the square footage, so the size of the pond directly impacts the liner cost. Liner type also makes a difference:
- PVC liners: $1 – $2 per sq ft installed
- EPDM liners: $2 – $4 per sq ft installed
- Bentonite clay liners: $1 – $1.50 per sq ft installed
Thicker liner materials tend to be more durable and provide better protection. For large ponds, installing an underlayment like sand or padding beneath the liner offers additional stability and cushioning.
Pond Shape
The shape of the pond affects the quantity of materials needed. Rectangular or square ponds are often less expensive than curved, oval, or irregularly shaped ponds. When calculating liner requirements, remember that rounded edges need extra material to overlap.
Location
Where the pond is positioned on the property also impacts construction costs. Key factors include:
- Accessibility for equipment and delivery of materials
- Soil conditions and ground preparation needs
- Proximity to electrical and plumbing hookups for pumps/filters
- Local labor rates if hiring a contractor
A remote or difficult to reach location may require additional excavation work and costs to transport supplies. The soil and terrain underneath the pond must be leveled and compacted to create a stable base.
Pond Edging
Edging materials give the pond definition, help contain the liner, and provide decorative appeal. Typical edging options include:
- Rocks
- Landscape timbers
- Stacked block retaining walls
- Poured concrete
- Brick or paver stones
Simple stacked stone edges cost around $5-10 per linear foot. More elaborate paved or mortared edging can run $15-40 per linear foot. The complexity of the pond shape will determine the total edging perimeter and materials required.
Additional Pond Features
Optional enhancements and accessories also contribute to the overall budget for an above ground pond. Some popular additions include:
- Waterfalls
- Fountains
- Boulders
- Plants
- Fish
- Lighting
- Decorative bridges
Items like fountains, waterfalls, and colored lighting help create drama and ambiance but add hundreds or thousands of dollars in expenses. Landscaping finishes like plants, rocks, and hardscaping around the pond also boost costs.
Pumps and Filters
Mechanical equipment is essential for proper pond circulation, filtration, and maintenance of water quality. Here are average price ranges for key components:
- Pump – $100 – $400 depending on gallons per hour (gph) flow rate
- External filter system – $200 – $1,000 based on gph ratings
- UV clarifier – $150 – $300 depending on pond size
- Plumbing fittings, tubing, valves – $150 – $300
Sufficient pumping capacity must be installed to circulate all the water in the pond. All equipment should be sized appropriately for the volume of water in the pond.
Professional Installation Cost
Hiring a qualified pond contractor to handle the entire installation process comes with added costs but can save headaches and avoid problems. Average labor rates range from $50 – $100 per hour, with total installation fees typically running:
- 10% – 25% of the cost of materials for small backyard ponds
- 25% – 45% of the cost of materials for large or complex ponds

Summary of Cost Factors
To recap, the major elements that impact the overall budget for an above ground backyard pond include:
- Pond size – surface area and depth
- Liner material selected
- Edging type
- Special features like fountains or waterfalls
- Pumps, filters, plumbing
- Excavation needs
- Surrounding landscape finishes
- Professional installation fees
With careful planning and smart pond design, you can control costs while still achieving a beautiful new water feature in your yard.

How to Save on Pond Building Costs
For homeowners looking to DIY and keep pond expenses lower, here are some tips:
- Select regular PVC liner over reinforced material
- Use gravel or landscape timber edges
- Start small and expand later
- Minimize accessories like waterfalls
- Buy pond supplies online
- Shop end of season sales
- Rent excavation equipment
With careful planning and budgeting, you can create a beautiful above ground pond and enjoy the benefits of water in your yard within almost any price range.
Conclusion
Building an above ground pond involves significant investment, with costs ranging from a few thousand dollars for a small wildlife pond up to $15,000 or more for an expansive water feature. The exact budget depends on factors like the pond size, depth, liner type, accessories, landscaping, and professional installation fees. With some DIY effort and smart design choices, you can construct an attractive pond and new ecosystem within reasonable costs limits. Proper planning and using cost-saving techniques can help you control expenses while still achieving a stunning new focal point in your landscape.
