Small Koi Pond Ideas for Small Gardens

A small koi pond need not be minimal! Extra attention to detail can make it larger than life. This pond makes use of several organic and inorganic elements to establish a cohesive look that wants for nothing. An elevated wooden bucket and freeform structure are used to create an understated waterfall. The dark colors help bring out the marginal irises, grasses, potted cacti, and creeping edge plants.

The grey structures, such as the piled rock slabs, stones, square planter, and bench, help draw attention to the pond water. Notice the perfect number of floating lilies, which provide some shade and protection to the pond inhabitants. Lastly, a ceramic frog that blends into the overall design adds a bit of whimsy and character to the pond.

Imagine looking out into this stunning pond while having your morning coffee. Even limited square footage in a suburban garden can be utilized to create an unforgettable attraction. A stone border provides for easy maintenance, effectively hides pond lining, and helps accentuate the colors of bromeliads and overhanging ferns.

Note the singular tree, with branches that can easily be pruned back each year to regulate the shade level on the pond. The Buddha sculpture adds an oriental finishing touch, and seems to contribute vertical interest as well.

Using piles of light grey slabs to create an organic division between the patch of soil and the small pond, this design almost looks like a pond within a pond. It has a minimalist overall appearance, with foliage being the star of the show. The elements certainly won’t distract from koi colors and patterns either. Just a few fish should be enough for a pop of color and movement.

This design has much potential for development; the concrete flooring adjacent to the pond can be made into a seating area for leisurely pond-viewing. The edge plants will also likel spread out to create a striking sea of greens around the pond.

This tropical-themed small pond has it all! The mini waterfall serves multiple purposes; it oxygenates the pond water, creates a subtle current, adds dimension to the pond, and is a sensory pleasure to the eyes and ears. The elevated rock wall and rustic sculpture enhance the natural appeal of the pond and complement the surrounding plants.

The palm tree adds a flair of drama and texture while shading the water and keeping it cool. Look closely at the left-hand corner, and you’ll find that the pond drains into another waterfall, which presumably flows into another water feature. This goes to show that you can have a system of differently-sized ponds on multiple levels!

Starved for space or wanting to create a separate small pond for fry? This simple pond design affords protection from the elements and can fit into an area of just 5×5 square feet. Materials, such as the tank and bordering stones, are relatively cheap and easy to acquire. The organic outline of the pond makes it look less rigid and helps make up for the lack of pond plants, which may suffer under shade.

This type of set-up is great for observing a few fish or for acclimation and quarantine, as it requires minimal maintenance and can be kept bio-secure.

Koi Pond Designs with Planted Margins & Edges

This pond design is highlighted by herbaceous marginal and edge plants that are distinguished by their large leaves. On the right is a stunning circular-leafed edge plant with a tolerance for wet feet! Notice that smaller counterparts are situated in the pond itself, creating the illusion of connectivity and fertility.

On the opposite side are equally stunning, yet tapered leaves that create a natural backdrop for the pond. Its spread is limited just enough to not distract from the spray of bamboo shoots in the background. Patches of trailing plants creep into the pond’s margins and soften the appearance of stones.

Pay close attention to the pond edges, and note the nifty use of the ground cover plants. They grow from spaces between the rocks, giving the pond a more natural look. An assortment of edge shrubs adds dimension, texture, and a gradient of greens to the pond. Due to their attractive foliage, they hold interest without the need for flowers and place more focus on the colors of the koi. A small fountain modestly sits in a section of the pond that almost seems separate due to a natural boundary of floating fronds.

This absolute stunner of an elongated pond is undeniably enhanced by a wide variety of pond edge plants. Though they are neatly pruned to retain a particular shape, many thoroughly hide the rough rock border of the pond. This technique of growing them on an elevated yet sharp edge gives the illusion that their roots are situated in the pond itself. The striking differences in green hues and leaf shapes also add an element of prosperity. Apart from their aesthetic value, they provide a fair amount of shade along the borders of an otherwise fully exposed pond.

If you’d like your koi pond to attract wildlife, margins that are profusely planted with native grasses should do the trick! These will help little critters move in and out of the pond, while providing them with ample protection. Grasses are great for adding texture as well, especially because they contrast the smooth appearance of stones and water.

Trailing plants with shoots that extend into the pond’s margins provide safe havens and food for koi fry and tadpoles. Do note that these types of plants will require regular maintenance to prevent their shoots and leaves from outgrowing the pond.

Koi Pond Design Ideas with Waterfalls

Waterfalls aren’t a must, but they do add complexity and value to a koi pond. This simple waterfall allows water to stream out from a stone wall feature and dramatically flow over a coarse arrangement of rocks. This helps reduce the pressure from impounding water and regulates the current. Moreover, the koi stay happy and healthy in this oxygenated space despite the lack of submerged and floating plants. The waterfall contrasts the inorganic features of this pond, making it look livelier and more natural.

This design shows how a waterfall can dramatically change the appearance of a pond. Without it, the neat and seemingly stiff edges would make the pond look fairly plain. Even from a low height, the water flowing into the pond gives it an energetic and lively aspect. Another charming feature of this simple design is the pond’s bean-like shape. It gives the shallow pond a more organic finish. The nestled appearance, owing to a vine-covered wall that separates the pond from the slope, adds a theatrical flair as well.

The waterfall here creates a much-needed focal point that breaks through the slabbed pond border. It starts from an elaborate distance behind the pond, allowing for 2 major edge flows. The oxygen-rich water streams into a shallower section of the pond, directly opposing a deeper area that looks calmer and still (due in part to the floating leaf pads). This design brings to mind the myth of the golden dragon, which tells the story of golden carp rushing upstream and jumping past waterfalls!

This type of waterfall streams out of a small container with a few floating plants! Apart from being a focal point of the pond, it also creates a flow that pushes water from a slightly elevated section. If you look closely, you’ll see that there are two points of entry with small waterfalls flowing into the main pond. This dynamic design compels visitors to walk around the circumference and reflect on the movement of water.

Note the fiery potted crotons, animal sculptures, and colorful floaters – a combination that results in an ultimately playful air. Children will surely enjoy visiting this one!

The koi appear to be energetic and happy in this lively pond. The sloping concrete edges are perfectly offset by the steady stream of water. Darkening the underlying rock faces, the waterfall helps bring out the colors of edge plants and the patterns on the fish. It would certainly help regulate dissolved oxygen levels as well.

If the water pressure is strong enough, this type of pond may not require additional aerators. Nonetheless, a submerged oxygen source causes a flurry of fine bubbles to rise in the center of the pond.

Koi Pond Designs with Rock & Concrete Borders

Ponds like this can be quite a challenge to put together and would definitely require ample planning. The boulders make the pond look fixed in time and immune to harsh elements. As they weather all seasonal conditions, they maintain year-round interest. They also leave room for a grander stone waterfall, which must be situated at a height to amplify the size of the stones.

The boulders, which make the clumps of bordering stones look like pebbles, are also situated in the pond itself. They complement the structure of a low-growing bonsai close to the center of the pond.

In an environment that is naturally sprawling with greens, jagged rocks can be a welcome sight. They provide a well-defined border to this simple pond, which looks incredibly clear under full sun. A few aquatic grasses and lily pads contrast the brown-grey rock colors and balance out the rough border. Wildflowers likely grow past the rocks each spring (a few are seen on the left-hand side here).

Note the “Please keep children off the rocks” sign. To prevent accidents, you may want to consider using signage similar to this if your pond is open to visitors.


Koi pond with multiple depth levels and crude edges made up of big rocks

The crude edges of the thick, light-colored rocks are a fantastic contrast to the immaculately clear and still water. They don’t at all take attention away from the koi despite their size and abundance in this setup. Rather, they draw your eyes to the colorful fish. A few well-chosen shrubs and ground cover plants complement the green tinge of the pond water.

Note the multiple depth levels in the pond, which are easily created with the same rocks. A few are distributed on the pond bottom as well. It looks as though a strong downpour or flood could increase the water level, yet the pond’s overall appearance would remain unchanged.

A few flat-topped boulders can create viewing points from within the pond itself. However, do ensure that adult supervision is provided whenever children are present. The stunning rocks in this pond are so large that they dwarf even jumbo koi. Observe how their muted grey color and relatively smooth surfaces enhance the red to black patterns on the koi.

This type of pond edge goes so well with Kohaku, Sanke, and Showa varieties, which are treasured for the deepness of their colors and their defined patterns.

When large sections of pond edges are naturalized with trailing plants and rocks, a smooth concrete edge can help deepen natural colors. The smattering of fall leaves is especially vivid due to their contrast with concrete. Moreover, a flat edge such as the one seen here can serve as a safer spot for closely viewing and feeding koi. Staying balanced on rocks along a pond’s edge isn’t always easy!

If needed, a few large rocks and tufts of grass placed along the pond margins can help distract from the rigid appearance of concrete.

Koi Pond Designs with Arching Bridges

Bridges are actually a common feature of large Japanese koi ponds. They provide a safe yet prime spot for viewing koi. In oriental gardens, arched bridges have both practical uses and spiritual meanings. The one in this photo would allow pond visitors to quickly cut across the pond without having to walk all around it.

Culturally, this bridge may signify the journey from this world into the afterlife and how a commune with nature is vital for contentment and inner peace. If this bridge were colored red, it would also symbolize wisdom and transformation.

This simple bridge is evidently more symbolic or ornamental rather than practical. When a distinctly oriental theme is absent, it can enhance the pastoral image of a pond, especially if situated close to a cottage or in a rural area. The bridge here blends in with the rock border and does not distract from the rest of the pond. Overall, it has an understated look and complements the simplicity of its surroundings.

Koi Pond Designs with Edge Seating

If you’ve put loads of time and effort into designing, constructing, and maintaining an ornamental pond, you would understandably want to look upon it with satisfaction and pride. If the weather is agreeable, an afternoon spent by a koi pond would be nothing but blissful. With a few garden chairs, benches, and tables, a small group can relish in the stress-relief that a pond would provide.

This koi pond is attractive and colorful enough to be a firm focal point even when other attractions are present. Thus, furniture with filigree simply enhances its overall design instead of becoming a distraction.

When choosing furniture to go with more natural-looking ponds, keep in mind that wooden chairs would always be a good idea. The only downside is they can be more difficult to clean and maintain, especially if birds frequently perch on them or constant rainfall damages the wood. Here, the wooden chairs perfectly blend in with the surrounding trees and shrubs.

They are also placed along a lovely stone path and close to the more naturalized edge of the pond. What a tranquil spot to enjoy nature!

Oriental-Themed Japanese Koi Ponds Designs

The Japanese and Chinese are definitely experts when it comes to designing koi ponds, so it makes sense to take inspiration from them! These stepping stone blocks, placed around massive crimson jars, make the pond a feature that is meant to be interacted with or walked through. This type of design, which likely incorporates

Feng Shui principles, would look great next to domineering buildings that require a touch of nature for a more relaxed exterior. The finishing touch that the long-stemmed leaves provide denotes a sense of weightlessness, which contrasts the firmness of the blocks and jars.

The key to a well-executed oriental-inspired design is a balanced distribution of features around a focal point. In the center of this koi pond stands a miniature pagoda. Pagodas are culturally important in Far Eastern culture. They are hollow, multi-tiered structures that some religious sects would use for ceremonies and worship.

Miniatures such as the one here are often used as sculptures in Zen gardens. One might say that this pond design induces a state of Zen because of its cohesive qualities. Even the lily pads are positioned with intention throughout the pond.

Nothing screams “oriental” more than the combination of koi and a humble bonsai tree. Like the pagoda above, it is placed in the center of the pond and the fish can swim in circles around it. Bonsai trees are a natural treasure in Japan and their cultivation is considered a serious art form. They require skill, patience, and open-mindedness.

Aquascaping and bonsai cultivation often go hand in hand as the complete pond can represent a larger setting (think of a tree in an ocean, for example). This physical ideation touches upon the fragility and fluidity of life.


Small koi pond with a Buddha statue and ferns

There are many types of Buddhist statues, and the one here is called the Bumisparsha Buddha or “Calling the Earth to Witness” Buddha. It should supposedly face the east, where the sun rises, as it represents enlightenment, wisdom, and eternal knowledge. When decorating an oriental-themed pond with sculptures, it would be wise to look into their cultural history and significance.

Many pond owners tend to invest in these fixtures just for their aesthetic appeal, but a little bit of research can bring more value to them. Knowledge and awareness can help you achieve a more authentic and culturally respectful design.

Sheltered & Raised Koi Ponds Designs

Though a fair amount of sunshine can be good for koi and would help regulate water temperature, ponds that are located in intensely hot areas will need some form of shade. If located in a southern region of the US, for example, you might consider building a pond in a semi-sheltered area or one that receives filtered light.

This simple koi pond is easy to maintain as cleaning its features would be relatively straightforward. Its elevated walls and roof prevent run-off, decaying leaves, and other foreign materials from easily entering the pond.

Partly cast in shade and fenced in, this semi-sheltered koi pond is ideal for urban areas with minimal space. Likely a brief attraction for stalled drivers and passersby, it provides a welcome respite from scenes of everyday traffic. Not everyone can be spoilt for choice when it comes to pond location and size, and this design fully maximizes the limited real estate! Note where the lily pads are situated – they must be placed on the sunlit side of the pond as they need to photosynthesize. They also help shade fish in this area.

This rectangular pond brings color and texture to this shaded space. Based on the reflection on the pond, it appears as though the roof above should provide the pond with filtered light through the middle of the day. Otherwise, the healthy greens would not be able to obtain the necessary sunlight to survive. The emergent marginal grasses contribute much-needed character and texture, and they help offset the rigidity of a well-defined pond edge.
