There’s something incredibly relaxing about watching these graceful creatures swim through the water, and many homeowners are eager to create their own backyard oasis. Before installing one, the main question people ask is ‘how much does a backyard koi pond cost?’

So, we’re answering that question in the form of a blog post! Keep reading to find out backyard koi pond costs and what can change them for you.

What Does A Backyard Koi Pond Cost To Install?

Cost To Maintain A Backyard Koi Pond

Part of the cost for a koi pond is routine maintenance, which you need to do to keep it healthy and beautiful. The cost to maintain a koi pond can be between $500 and $1,500. It mainly depends on who you hire, the size of your pond, how long it’s been since the last cleaning, and what kind of maintenance your contractor does. There is plenty that homeowners need to know about koi pond maintenance.

Factors That Can Affect The Cost Of A Koi Pond

DIY vs. Professional Installation

You can install your own koi pond for anywhere from a couple of hundred dollars to a few thousand. Installing a koi pond isn’t easy. Prepare to put in a lot of hours and energy. You need to make sure everything works, or you could hurt your property and fish. These koi ponds usually involve a smaller pre-fabricated tub and basic pond equipment. DIY ponds tend to look more artificial, and people don’t tend to love how this looks. Due to this, many people call us out to renovate theirs.

A professional pond installation will cost more, but you’ll love the end result better than a DIY pond. Plus, you can feel more confident knowing pond professionals were handling your project, meaning it’ll function properly and that it comes with a warranty.

*Our ponds are different because they are ecosystem ponds, meaning they are more self-sustaining and look more natural. This means they look better and are lower maintenance than other koi ponds.

Pond Size And Shape

The size and shape you want will change the cost of your backyard koi pond because it affects the amount of labor and materials it needs.

Larger ponds take more time, effort, and materials to create. Smaller ponds are much easier and quicker to install.

Many pond installers have certain shapes their ponds come in. These usually include oval, circular, and more. Custom shapes cost more because installers have to figure out how all of the parts are going to work in this new shape.

Additions will cost more, but they can also help you enjoy your backyard koi pond way more.

A few fun additions include underwater LED lights, aquatic plants, additional waterfalls, and fountains. Some additions can help you do less maintenance on your pond. These include an auto-filler, IonGen water cleanser, solids handling pump, and more.


Koi fish in a backyard pond

One of the biggest factors in the cost of a backyard koi pond is the fish themselves.

Koi are a type of carp, and they can grow to be quite large – up to three feet in length. As a result, they require a lot of food, and they produce a lot of waste. This isn’t as much of a problem if you have an ecosystem koi pond because then your koi can feed themselves, and the pond can handle much of their waste.

You’ll need to invest in a proper filter system for how many fish you want to add and keep an eye on the water quality. Another investment can be in ways to protect your fish from predators like raccoons and herons. Knowing how to care for koi fish is important if you want to add them to your backyard pond.

Material Choices

Material choices can have a big impact on backyard koi pond costs. For example, a concrete pond will be more expensive than a liner pond.

The type of liner you choose will also affect the cost. EPDM liners are the most expensive, but they’re also the most durable. PVC and fiberglass are less expensive options, but they may not last as long.

Many pond builders will just install the liner for the bottom of your pond. This can keep the cost down, but your pond will look more artificial. We prefer putting rocks and gravel over the liner. This protects it from some forms of damage and makes your pond look more natural.
