These things have become backyard gold, and for good reason.

Why Poly Tanks Are Actually Brilliant
Alright, so lets clear this up right out the gatepoly = plastic. These are the black or grey tubs used on farms to water animals.
Doesnt sound sexy, but hear me out. Unlike their galvanized steel cousins, poly tanks dont rust.
Theyre lighter too, which means you dont need to hire a crane just to move the thing into place.
Also, theyre smooth inside, so none of that scratchy industrial feel. And if youve got kids or pets running around, thats a big win. Saltwater-friendly too.
Thats another bonus if you prefer natural pool treatments or just want to soak without feeling like youre in a science experiment.

Setup Basics (Without Getting All Technical)
You dont need to be a builder or plumber to get one of these running.
Youll want a flat spot, ideally with good drainage, and close to a power source if you plan on running a filter.
Thats it for groundwork.
Heres what I usually see people doing:
- Base layer A circle of compacted gravel or sand works. Some folks put down pavers or a wooden frame.
- Pool filter setup Most go for an Intex pump or aquarium-style filter for smaller tanks.
- Optional heating Solar mats or a propane heater can do the trick.
- Surrounding it This is where the magic happensdecks, stones, plants, privacy screens.
Honestly, once the tanks filled, its already doing 80% of the work. The rest is you making it fit your style.
Pool Surrounds That Totally Change the Game
Heres where you can get creativeand trust me, people go all in.
Decked Out Like a Dream
One of the most popular moves is building a low wooden deck around the tank.
It blends it into your space and makes it feel built-in, not plonked there. People even carve in steps or little benches so its easy to lounge around the edges.
I saw one setup where someone even tiled the inside of the poly tank. Looked like a resort.
Slightly Sunken, Totally Chill
Want that in-ground pool feel without the in-ground pool cost? Bury the tank halfway.
Just dig a shallow pit, drop in your poly tank, and surround it with pavers, bricks, or smooth river stones. It creates this natural lagoon effect, especially if youve got greenery nearby. Feels like a hidden watering hole.
Backyard Spa Vibes
If youre more about that soak in peace life, think spa. Wrap the tank in bamboo panels or vertical cedar slats, string up some outdoor lights, maybe hang a little curtain or two.
Add a bench with rolled towels and youre good to go. Instant resort.
Bright and Bold
Not into the rustic look? Thats finemake it pop. Spray paint the outside a bold colour (black, teal, even pink).
Some folks do patterns or stripes with stencils. Looks awesome against gravel, tiles, or fake grass. Funky cushions and floating drinks tray, and boomits giving magazine feature.
Tips That Make All the Difference
People dont talk enough about the little things. The details are whatll make your setup feel complete.
- Level ground is non-negotiable. Even a slight slope can turn your peaceful soak into a weird bathtub ride.
- Add a cover keeps the bugs and leaves out. Some folks even use round trampoline covers.
- Floating solar lights game changers at night.
- Plants, plants, plants Tall grasses, potted trees, or trailing vines bring life to the setup.
- Kid safety Think fencing or a lid if youve got little ones or pets around.
- Make it match your vibe If youve got boho furniture, lean into that. If your house is modern and white, go clean and minimal with your tank setup too.
