Looking for an easy DIY water feature you can install in an afternoon? The Blue Thumb Klamath Basin Fountain Kit might be exactly what you’re looking for.
For years, I dreamed of adding a peaceful water feature to my vegetable garden. Every time I visited a botanical garden or walked through a beautifully landscaped neighborhood, I found myself drawn to the fountains. There’s something about the sound of running water that instantly makes a garden feel calmer, more inviting, and just a little more magical.
The problem? I had convinced myself that installing a backyard water feature would be complicated.
I pictured hiring a contractor, dealing with plumbing, pouring concrete, and spending an entire weekend digging a massive hole. It sounded like one of those landscaping projects best left to the professionals.
So when Blue Thumb reached out about installing their Klamath Basin Fountain Kit, I was excited—but admittedly a little intimidated. I even recruited my dad to help.
Now that we’ve finished the installation, I can confidently say I was overthinking the entire project.
From the first shovel full of dirt to turning on the fountain, our installation took less than two hours.
If you’ve been searching for DIY pondless water feature ideas, backyard fountain ideas, garden water features, or how to install a pondless fountain, here’s exactly how our Klamath installation went.
Why I Chose a Pondless Water Feature
Over the past few years, I’ve slowly transformed this previously unused area of our yard into a space that’s beautiful, functional, and full of life.
We’ve planted privacy hedges, layered in flowering perennials, built raised vegetable beds, and created a space that attracts plenty of pollinators.
But something still felt like it was missing.
I wanted to introduce another element to the garden—something that would add movement and sound, even when nothing was blooming.
A pondless fountain was the perfect solution.
Unlike a traditional pond, a pondless water feature doesn’t have an exposed pool of water. Instead, water is stored in an in-ground fountain basin hidden beneath the decorative stone.
A submersible pump inside the basin sends the water through tubing and up through the fountain. The water then flows back through the grate and screen into the basin below, where it’s continuously recirculated.
You get the relaxing sound and movement of running water without adding a traditional garden pond.
For our space and lifestyle, it was exactly what I wanted.
What Is the Blue Thumb Klamath Basin Fountain Kit?
The Klamath is a handcrafted GFRC bubbler rock fountain designed to look like natural stone.
GFRC stands for Glass Fiber Reinforced Concrete. The Klamath is molded from an actual stone boulder, giving it the texture and appearance of natural rock without the extreme weight of using a solid boulder as a fountain.
The Klamath itself measures approximately 18 inches long by 19 inches wide by 16 inches high, making it large enough to create a focal point without overwhelming a smaller garden bed.
The kit pairs it with Blue Thumb’s compact 2x2 fountain basin, which measures approximately 25 inches square and only 8 inches high.
That shallow basin ended up being particularly helpful during our installation—but more on that in a minute.
What Comes With the Blue Thumb Klamath Fountain Kit?
One thing I appreciated about this project was that the major components needed to create the fountain came together as a kit.
The Klamath Basin Fountain Kit includes:
-
Klamath handcrafted GFRC bubbler rock
-
2x2 fountain basin
-
Fountain basin grate
-
Polymesh screen
-
370 GPH Mag-Drive pump
-
Required tubing and plumbing components
-
Installation instructions
I also used Blue Thumb Mixed Polished Pebbles around the fountain to conceal the basin and create the finished look you see in my garden.
The decorative stone is optional and sold separately, so you can customize the area around the fountain to complement your own landscape.
How to Install the Blue Thumb Klamath Basin Fountain Kit
Here’s how our installation went from start to finish.
Step 1: Choose the Right Location
Before we started digging, we spent some time deciding exactly where the fountain would make the biggest impact.
I wanted it close enough to my raised vegetable beds that I could hear the water while gardening, but I also wanted it to feel like a natural part of the surrounding landscape.
I ultimately chose a spot nestled into the garden where the fountain could become part of the planting rather than looking like something we simply dropped into the yard.
You’ll also need access to an appropriate outdoor grounded GFCI outlet for the fountain pump.
And, as with any project that involves excavation, make sure you know what’s underground before you start digging.
Step 2: Mark and Dig the Hole for the Fountain Basin
This was the most labor-intensive part of the entire project—and even this went much faster than I expected.
We marked the footprint for the 2x2 fountain basin and started excavating the soil.
Then we hit an unexpected obstacle: sprinkler lines.
For a second, I thought our afternoon DIY project was about to turn into rerouting part of our irrigation system.
Thankfully, the Klamath’s fountain basin is only about 8 inches high.
Because our irrigation lines were positioned in a way that didn’t interfere with the basin, we were able to position it without rerouting our sprinkler system.
Every irrigation system is different, so don’t assume you can place a basin over existing lines. Make sure you’re not damaging, crushing, or interfering with irrigation or other underground utilities.
For us, though, the shallow profile of the basin made installation much easier than I anticipated.
Step 3: Prepare and Level the Base
Once we reached the proper depth, we prepared the bottom of the excavation and made sure we had a stable, level base.
This step is worth taking your time with.
According to Blue Thumb’s installation instructions, if you’re working with unstable soil, you can excavate an additional three inches and add approximately three inches of crushed rock or gravel to create a more stable foundation.
Our existing soil was stable enough that we were able to level the base and move forward.
We then lowered the fountain basin into position and checked it with a level in multiple directions.
Blue Thumb recommends keeping the top edge of the basin approximately one inch above the surrounding grade.
This helps prevent surrounding soil, mulch, and runoff from washing into the basin.
Once we were happy with the position, we carefully backfilled around the basin for support.
Step 4: Install the Pump, Grate and Screen
Next, we installed the pump inside the fountain basin and connected the included tubing.
The tubing runs from the pump up through the basin grate and polymesh screen before connecting to the fountain above.
The grate provides the support surface above the reservoir, while the polymesh screen helps prevent the decorative stone and larger debris from falling into the basin.
One important tip: don’t cover the screen with soil or mulch.
You want water to be able to drain freely back into the reservoir without sending loose landscape material into the pump system.
At this point, I started realizing just how simple this fountain system actually was.
There was no permanent household plumbing to install. The water simply recirculates between the Klamath fountain and the basin underneath it.
Step 5: Position and Connect the Klamath Fountain
Next came the fun part: putting the Klamath bubbler rock into position.
The fountain connects to the tubing coming from the pump through the connection underneath the rock.
Because the Klamath is made from Glass Fiber Reinforced Concrete rather than solid natural stone, you get the substantial appearance of a rock fountain without having to maneuver an incredibly heavy boulder into your garden.
Once it was connected and positioned exactly where we wanted it, the project really started coming together.
Step 6: Fill the Fountain Basin and Turn on the Pump
This was easily my favorite part.
We filled the fountain basin with water until the water level reached approximately the bottom of the grate.
Then we plugged the pump into our outdoor GFCI outlet.
Within seconds, water began bubbling out of the Klamath and flowing over the stone.
After spending years imagining a water feature in this part of the garden, seeing—and hearing—it running for the first time was incredibly satisfying.
Step 7: Adjust the Water Flow
Once the fountain was running, we checked the water flow and made sure we were happy with the bubbling effect.
You want enough flow to create the sound and movement you’re looking for without sending excessive amounts of water outside the footprint of the basin.
This is also where personal preference comes into play.
A gentler flow creates a softer bubbling sound, while more flow can make the fountain a more noticeable feature in the landscape.
Step 8: Finish With Decorative Stone
The final step was hiding the fountain basin.
I used Mixed Polished Pebbles from Blue Thumb around the Klamath, covering the visible grate and screen while still allowing water to drain back into the reservoir below.
This finishing step made a huge difference.
The polished stone conceals the mechanical components and helps the fountain look like an intentional part of the surrounding landscape.
Once everything was finished, it looked like the Klamath had always belonged there.
How Long Does It Take to Install a Pondless Fountain?
Our entire Klamath fountain installation took less than two hours, including digging the hole.
Your installation time will obviously depend on your soil conditions, location, existing landscaping, and whether you encounter underground irrigation or other obstacles.
But I was genuinely surprised by how quickly this project came together.
The part I had built up in my head as a major landscaping project ended up being an afternoon DIY.
Did I Really Need Help Installing It?
I’ll admit it: I asked my dad to help because the idea of installing an entire backyard water feature sounded intimidating.
In my mind, this was going to be a huge project.
After actually doing it, I realized I had completely overestimated how complicated the process would be.
If you’re comfortable digging, using a level, connecting tubing, and positioning the fountain, this is a very approachable DIY project.
Having another person around certainly made things easier, particularly when positioning everything, but I would feel much more confident tackling another pondless fountain installation after seeing how the system works.
The Finished Klamath Fountain
In less than two hours, we transformed an ordinary section of the garden into one of my favorite spaces in our backyard.
And what surprised me most wasn’t necessarily how the fountain looked.
It was how much the sound changed the space.
The gentle bubbling adds an entirely different feeling to the garden. It makes this area feel peaceful, relaxing, and more like a destination rather than simply a place where I grow vegetables and flowers.
It also introduces another element of nature into the landscape.
Within hours of finishing the installation, birds were already stopping by to investigate.
I have a feeling this is going to become one of my favorite garden features.
My Tips for Installing a DIY Pondless Fountain
If I were installing another pondless fountain tomorrow, these are the things I’d keep in mind:
-
Spend extra time getting the fountain basin level.
-
Make sure you have a stable base before installing the basin.
-
Follow the manufacturer’s recommendation to keep the top edge of the basin approximately one inch above grade.
-
Know where irrigation lines and underground utilities are located before digging.
-
Don’t cover the polymesh screen with soil or mulch.
-
Rinse decorative stone before placing it around the fountain to reduce debris entering the basin.
-
Keep a wheelbarrow nearby for excavated soil.
-
Check your water flow before adding all of your finishing stone.
-
Make sure you can easily access the basin and pump for future maintenance.
-
Remember that some water will naturally be lost to evaporation and splash, so periodically check the basin’s water level.
Frequently Asked Questions About Pondless Fountains
What is a pondless fountain?
A pondless fountain is a recirculating water feature without an exposed pond. Water collects in a hidden basin below the fountain and is pumped back through the feature continuously.
It’s a great option if you want the sound and movement of water without installing a traditional backyard pond.
How long did the Klamath Fountain Kit take to install?
Our installation took less than two hours from the time we started digging until we turned on the fountain.
Installation time can vary depending on your soil, landscaping, and site conditions.
Is the Blue Thumb Klamath Fountain Kit beginner-friendly?
I found the installation much easier than I expected.
The most labor-intensive part was digging and leveling the area for the basin. Once the basin was installed, assembling the pump, tubing, grate, screen, and fountain was relatively straightforward.
Do you need plumbing experience to install a pondless fountain?
We didn’t.
The Klamath is a self-contained, recirculating fountain system, so you aren’t connecting it to your home’s permanent plumbing.
The submersible pump moves water from the fountain basin through tubing to the Klamath, and the water flows back into the basin to be used again.
How much water does the Klamath fountain basin hold?
Blue Thumb lists the 2x2 basin used with the Klamath kit at approximately 12 gallons.
You’ll need to periodically replenish water lost through evaporation and splash.
Is a pondless fountain easier to maintain than a traditional pond?
A pondless fountain eliminates many of the considerations associated with maintaining an exposed garden pond because the reservoir is hidden underground.
You’ll still want to keep debris out of the basin, periodically check the pump, and maintain an adequate water level.
Can you install a pondless fountain if you have sprinkler lines?
It depends on your individual irrigation system.
We uncovered several sprinkler lines while excavating our fountain area. Because of their position and the relatively shallow 8-inch basin, we were able to install our fountain without rerouting them.
Always locate underground irrigation and utilities before digging and make sure the basin won’t damage or interfere with existing lines.
Does the Klamath Fountain Kit include decorative stone?
Decorative stone is not included with the standard Klamath Basin Fountain Kit.
For our installation, I used Blue Thumb Mixed Polished Pebbles to cover the grate and create the finished look around the fountain.
Is a Pondless Water Feature Worth It?
For our garden, absolutely.
This project completely changed the atmosphere of this part of our backyard in a single afternoon.
For something that took less than two hours to install, the impact feels much bigger than the amount of work involved.
The sound of running water makes the garden feel more peaceful, more inviting, and more complete.
And because the Klamath looks like natural stone, it fits beautifully into the surrounding landscape instead of feeling like a separate decorative object.
If you’ve been considering adding a DIY backyard fountain or pondless water feature but assumed installation would be too complicated, this project might surprise you as much as it surprised me.
Sometimes the projects that seem the most intimidating turn out to be the ones that completely transform a space.
