Few people have any idea what a koi pond costs, and most contractors won't say until they're standing in your yard. Here are all seven of our koi pond packages, what each one includes, and what changes the price on your lot.
Our koi pond packages start at $9,195 for a 6' x 8' pond with a waterfall and step up to $122,500 for a 25' x 30' pond with a 3 foot waterfall, 10 foot stream, custom wetland filter and intake bay. Most of the price difference between packages comes from size, filtration and boulder tonnage. Every price below is a starting price. Electrical is not included in any package, and financing is available.

What makes a koi pond cost more or less than the package price?
The package sets the starting point. Your site decides the rest.
Access. A machine that can drive into the backyard digs a pond in a fraction of the time hand crews need behind a narrow gate or down a steep slope.
Soil and rock. Piedmont red clay is heavy to move and haul. On many Gaston County lots, rock can appear at shallow depth. Our ponds are dug to a minimum depth of 2 feet, so shallow rock adds work.
Boulders. Each package lists its tonnage. Upgrading to more or larger specimen stone raises the price; staying at the listed tonnage keeps it there.
Electrical. Not included. The distance from your panel or an outdoor outlet to the pump sets the electrician's cost.
To spend less, choose a smaller package, keep the boulder tonnage as listed, place the pond where a machine can reach and power is close, and add lighting later. Consider a pond over a cheaper option when you want fish and a living ecosystem. If you want moving water without the upkeep, a pondless waterfall starts at $6,000.
Pricing
What does a koi pond cost to keep up?
Plan on routine care each year, either your own time or a maintenance package. Ours run from $1,980 to $7,000 a year depending on water surface area and visit frequency. See pond maintenance pricing. In the Charlotte area, fall leaf drop from mature oaks makes netting the single most important seasonal task.
Questions
Frequently asked questions
Our smallest package is a 6' x 8' pond with a waterfall, starting at $9,195. It includes a Signature Series 200 skimmer, Signature Series 1000 BioFalls, an AquaSurge 2000 pump, a 10' x 12' 45 mil EPDM liner with underlayment, up to 3 tons of boulders, gravel and beneficial bacteria. Electrical is not included. It fits well near a patio or in a front yard bed.
Because it varies more than anything else on the job. The cost depends on the distance from your electrical panel or an existing outdoor outlet to the pump location, and that work must be done by a licensed electrician. We'll point out the likely run during the site visit so you can get it priced before you commit.
A skimmer pulls leaves and debris off the surface and houses the pump. A BioFalls or wetland filter is where beneficial bacteria break down waste so the water stays clear. Our two largest packages use a custom wetland filter, and the largest replaces the skimmer with a custom intake bay, because big ponds need more biological filtration.
No package lists fish. Each pond package includes beneficial bacteria to start the biological filter, and we'll talk through when and how to add fish once the pond has settled in. Our koi pond builds page covers fish choices in more detail.
Yes, financing is available on every pond package. Financing spreads the cost over time but does not lower the total project price. If you plan to finance, mention it when you book your call so Brian can help match the package size to a comfortable payment.
Pick the package that looks closest, and Brian will tell you on a 30-minute call what your yard will add or save. See finished work in our pond and water feature projects.
