What Customers Are Saying

The pond liner is well-suited for small water features and easy to install, with customers praising its sturdy construction and organic shape. However, some reported issues with the liner developing holes or leaking after a short period of use, and concerns about the quality and durability of the plastic material being inferior compared to previous versions. While many were satisfied, a significant number felt the product did not meet their expectations for the price.

Great backyard pond!

Would Recommend

Great addition to the backyard. Looks great and majes a great home for Koi. It's deep enough for them to winter safely and large enough for them to swim freely! It's sturdy and will hold up well for many years.

Pond Liner Also Great For ZEN water feature!

Would Recommend

it was the perfect size for my water feature that I wanted to put into a small space, not for fish, but just for prettiness. The length of it and the easily movable weight of it, made it easy to work with, and I love the shape of it too, and the two different depths 18" &12"

Garden Pond Liner Longevity

Would Recommend

I purchased this exact same pond liner 13 years ago from Lowes....that's how long this liner last before the ground settled and a crack appeared. I am so pleased that this exact liner is still being sold because all I had to do was pull up the old one and drop this one in. I certainly got my money worth. Great liner and not expensive.

Excellent quality at unbeatable cost.

Would Not Recommend

The pond is great. Granted I’ve only had it for a couple of weeks, but so far so good. It seems like great quality, especially considering the price. I did not find many other options out there for under $100. Digging the hole was not hard. I’ve installed the small waterfall that runs into the pond and it works perfectly. There’s plenty of room in the pond for it.

Make sure it sits completely level before filling

Would Recommend

I’m so pleased with this pre-formed pond liner. At 50 gallons, it was the perfect size for my back yard. It’s strong and sturdy and meets all my goals for this calm water space. I’ve been able to create a serene, calm pond that gives me joy!

It's nice but has a manufacturing defect

Would Not Recommend

I have bought 2 of these. I did my own project and built my own pond in front of my house using block from Lowe's. This worked great and looked good. Unfortunately after only less than 2 years it developed a hole in it. I thought it was something I was doing. Then when I went to replace it I bought another one and noticed in the same spot that the plastic is thin. It's on the same spot on the original one I bought. It's a manufacturing defect. They're mold sucks. I went through every one of them...

It is not big, nor small, just the right size for a small backyard. Haven't put it in the ground yet. I will share a picture of it when it's set in the ground.

Make sure it is level

Would Recommend

I like it a lot. It looks a lot smaller once it is in the ground. Also, make sure it is level on all sides and after leveling and filling with water wait 24 more hours! Mine was level until the next day and one side sank 3 nches but, I used the pump to empty it out and add more sane under low end. Looks great now. I got the 8 inch waterfall too. Make very sure that is level for perfect even cascade.

Bowing after 5 days!

Would Not Recommend

Was told in store I could use this free standing above ground as long as the shallow end was supported but it is now bowing after barely one week of being filled completely. I’ll now have to find a totally different pond to use after getting mine fully setup less than a week ago!
