DIY Stock Tank Pool: Beautiful Backyard Upgrade or More Work Than It's Worth?
When one of our customers asked about adding a stock tank pool to their backyard, our first thought was: "Sure! How hard can it be?"
Several days, multiple trips to the hardware store, a few lessons learned the hard way, and more waterproofing coats than we originally planned later...
We had a beautiful custom stock tank pool.
Would we do it again? Yes. Would we want to do it at our own house? Only if we could hire someone else to build it.
Let's talk about why.
What Is a Stock Tank Pool?
A stock tank pool starts life as a livestock watering tank. With some modifications, waterproofing, filtration, and a little creativity, it can become a stylish backyard plunge pool that looks right at home on a patio or deck.
They're popular because they look fantastic in photos and can fit into smaller spaces where a traditional pool isn't practical.
What most social media videos don't show is everything that happens between "buy stock tank" and "relax with a cold drink."
Step 1: Etch the Tank
The first step is preparing the metal surface. We used a metal etching product on the inside of the stock tank to help the waterproof coating properly bond to the metal. Skipping this step would be like painting over a greasy wall and hoping for the best. Could it work? Maybe. Would we recommend it? Absolutely not. Proper preparation is what determines whether the coating lasts for years or starts peeling when summer temperatures arrive.
Step 2: Paint the Exterior
Now comes the fun part. The customer wanted something that looked more like backyard décor and less like farm equipment. So Craig painted the exterior black to give it a more finished, modern appearance. Was it necessary? No. Did it make a huge difference? Absolutely. Sometimes a little paint is the difference between: "There's a stock tank in my yard." and "Wow, that's a really nice pool."
Step 3: Level the Area
This step sounds simple. It isn't. Water weighs approximately 8.34 pounds per gallon. A stock tank pool can hold hundreds of gallons. That means if the ground isn't level, you'll discover it very quickly. Usually at the worst possible time.
Depending on the location, you may need:
Sand
Ground padding
Additional leveling work
Lots of patience
Getting this right helps prevent uneven pressure and improves the finished appearance.
Step 4: Install the Filter System
A stock tank pool isn't much fun if the water turns green. To keep the water clean, holes were drilled and a filter system installed. This part requires careful planning because once you drill a hole in a perfectly good stock tank... There's no "undo" button. Measure twice. Measure again. Then maybe measure one more time just to be safe.
Step 5: Waterproof the Interior
This is where the project became much more involved than most people expect. After preparing the surface, the interior was coated with waterproof epoxy. The first coat looked terrible. Seriously. If you've never worked with this type of product before, you'll probably spend several minutes wondering if you've made a huge mistake. You haven't. It just looks that way.
Work quickly! The product begins curing fast. This is not the type of project where you answer a phone call, grab a snack, and come back later.
Wear Safety Equipment! Gloves, eye protection, and proper ventilation are important. The goal is to build a pool, not create an exciting story for your doctor.
The First Coat Will Look Splotchy, that's normal. You May Need Multiple Coats. The final result required more coats than expected to achieve complete coverage. If Craig could go back and do one thing differently, it would be: Seal the sides first. Trust us on this one.
Step 6: Build a Small Equipment Deck
Once the plumbing and filter were installed, we wanted a cleaner look. The solution was a small deck structure that concealed the equipment. This step is optional, but it dramatically improves the finished appearance. Instead of seeing hoses and equipment, visitors see attractive woodwork. And that's generally preferable.
Step 7: Add an Access Door
A hidden filter system sounds great until maintenance day arrives. That's why an access door was added. This allows the owner to reach the equipment without taking apart half the project. Future You will appreciate Present You for thinking ahead.
Step 8: Add Steps
For the finishing touch, custom steps were built. Are steps required? No. Can you climb into the pool without them? Probably. Will it look as nice? Not even close. The steps helped transform the project from "DIY pool" into "intentional backyard feature."
The Question Everyone Asks:
Should You Build a Stock Tank Pool?
Our answer is: It depends. If You Love the Look... Yes. Absolutely. The finished product looks fantastic. It has a unique, custom appearance that you won't get from most store-bought pools. If aesthetics are important and you want a backyard feature that stands out, a stock tank pool can be a great investment.
If You're Looking for the Cheapest Way to Cool Off... Probably not. By the time you purchase all the supplies, the project can cost significantly more than people expect. It's also very time consuming.
If your primary goal is simply getting a pool for the family to enjoy this summer, a quality above-ground pool from a local retailer may be a faster and less expensive option.
Would We Build Another One?
For a customer? Sure. For one of our favorite customers? Definitely. For ourselves? Only if someone else volunteered to do all the waterproofing.
Final Thoughts
A stock tank pool is one of those projects that looks simple on social media but involves a surprising amount of planning, preparation, and labor. The good news? The finished result can be absolutely beautiful. If you're willing to invest the time, effort, and budget, you'll end up with a unique backyard feature that's sure to get attention.
