Above-Ground Pools
Intex vs Bestway: which above-ground pool to buy
Two brands own this category and they are closer than the internet suggests. The differences that matter are filtration, kit contents and what each will tell you before you buy.
Heads up: we earn a commission if you buy through the links on this page, at no extra cost to you. It never decides the ranking — here is how we pick and here is the full disclosure. Prices are checked automatically; last verified January 1, 1970.
The short version
- At the same size and price they are close. Anyone telling you one brand is decisively better is not comparing published specs.
- Intex publishes more. Both pump flow and system flow, on a per-model page. That is a real advantage when you are trying to size a pump.
- Intex’s cartridge ecosystem is bigger. Type A cartridges are the most widely stocked filter consumable in US stores.
- Neither publishes wattage. On the single input that determines your running cost, both are equally unhelpful.
The comparison criteria
We compared these on the things a buyer can actually verify before purchase: published capacity, published filtration figures, frame and liner construction as documented, kit contents, and consumable availability. We have not tested either brand’s pools and we do not claim to — see our methodology.
| Intex Prism Frame 12ft | Bestway Steel Pro MAX 15ft | Intex Ultra XTR 18ft | |
|---|---|---|---|
| Capacity | 1,718 gal | 3,955 gal (90%) | 6,981 gal |
| Wall height | 30 in | 42 in | 52 in |
| Pump flow | 530 GPH | 1,000 gal | 2,100 GPH sand |
| System flow published? | Yes — 475 GPH | Not stated | Not stated |
| Liner | 3-ply | Tritech 3-layer | 3-ply |
| Ladder + cover | Check SKU | Included | Included |
| Wattage published? | No | No | No |
Where Intex genuinely wins
Disclosure. Intex publishes both the pump flow rate and the system flow rate for its Krystal Clear pumps. That distinction matters more than it sounds: the headline number is what the pump moves, and the system number is what actually gets through once the cartridge is in the way. Your turnover math needs the second one, and Intex is the brand that gives it to you.
Consumables. Type A cartridges are stocked almost everywhere in the US, in multipacks, from both Intex and aftermarket makers. Bestway’s equivalents are available but thinner on the ground, and in July that difference is the difference between a five-minute errand and a three-day wait.
The top of the range. The Ultra XTR line, with its galvanized frame, inner and outer powder coating and a sand filter rather than a cartridge, is the most substantial thing either brand sells to homeowners.
Where Bestway genuinely wins
Kit completeness at the mid sizes. The Steel Pro MAX 15′ × 42″ publishes a ladder and cover as included, where the equivalent Intex size frequently depends on which SKU you land on. A kit that includes what you would buy anyway is a genuinely cheaper kit.
Liner marketing that is at least specific. Bestway names its three-layer construction (Tritech) and publishes comparative claims about it. Whether those claims are meaningful is a fair question, but a named, specified material is more checkable than “durable 3-ply”.
The 42-inch wall. Sitting between Intex’s common 30-inch and 52-inch options, 42 inches is a genuinely useful height: deep enough for adults to sit in properly, shallow enough to be forgiving of ground that is nearly but not perfectly level.
Where neither wins
Wattage. We checked both manufacturers’ published pump specifications and neither states power draw. That is the single most important input to your annual running cost, and it is unavailable before purchase from both of the brands that define this market. The number is on the pump label — read it on day one and use the table in our cost-to-run guide.
Who should buy which
Buy Intex if you want to size your filtration properly before you buy, if you value the widest cartridge availability, or if you are going large enough to want the Ultra XTR’s sand filter and galvanized frame.
Buy Bestway if you want a complete mid-size kit with the ladder and cover in the box, or if the 42-inch wall height is the right compromise for your yard and your family.
Buy whichever is in stock and cheaper if you are choosing between two similar sizes from each. At equivalent capacity and price, the published specifications do not support a confident preference, and anyone who tells you otherwise is not reading the same spec sheets. Size, kit contents and your yard are all bigger decisions than the badge — start with sizing.

Small yards and first-time owners
Intex Prism Frame Pool Set, 12ft x 30in
Intex
The size most people should buy first and the one most people talk themselves out of. 1,718 gallons is cheap to fill, cheap to treat, and forgiving of every mistake you are about to make.

Overall 8.6 / 10
What works
- A 12-foot circle fits in a yard where a 15 or 18 will not, once you allow three feet of walking space
- 1,718 gallons turns over in about 3.6 hours on the supplied 475 GPH system flow — so a short daily run genuinely filters it
- Cheapest of the frame pools to make a mistake in: a bad chemical week costs a few dollars, not a few tens
- Tool-free assembly is real, not marketing — this is a genuinely one-afternoon job
What doesn't
- 30-inch wall means shallow water and it warms and cools fast
- Small enough that three adults fill it
- The C530 is sized for exactly this pool and nothing bigger, so it does not carry over if you upgrade
Skip it if: Anyone planning to swim rather than sit. This is a cooling-off and playing pool and it is very good at that.
What it costs to run: The cheapest frame pool here to run, and the gap is not small. At the EPA WaterSense average of $6.06 per 1,000 gallons a fill is about $10. Its turnover math — 1,718 gallons at 475 GPH system flow — means roughly 3.6 hours per full turnover, so a 7-8 hour daily run is two full turnovers rather than a partial one.
One honest season: The cheapest setup that genuinely works for a season of real swimming. Nothing spare, nothing missing.

The honest middle of the market
Bestway Steel Pro MAX Pool Set, 15ft x 42in
Bestway
Fewer gallons and a shallower wall than the Intex flagship, which makes it easier to level, cheaper to fill and cheaper to keep clean. For most first-pool families this is the right size, not the compromise size.
Key specs
- Water capacity
- 3,955 gallons (90% full)
- Pump supplied
- 1,000 gal filter pump, Type III cartridge
- Liner
- Tritech 3-layer
- Included
- Ladder and cover
- Wall height
- 42 inches
- Pump wattage
- Not published by Bestway (US listing)

Overall 8.2 / 10
What works
- 3,955 gallons is roughly 43% less water than the 18ft Intex — that is 43% less chemical spend, every season, forever
- 42-inch wall is far more forgiving of a yard that is nearly-but-not-quite level
- Ladder and cover included
- Cartridge filtration means no sand to buy or change
What doesn't
- Cartridges are a recurring consumable, and in a busy pool you will rinse one weekly
- 42 inches is shallow for adults who want to actually swim rather than sit
- Wattage is not published, so the running-cost math needs the label on the box
Skip it if: Adults who want to swim lengths. At 42 inches you are sitting in it, not swimming in it.
What it costs to run: The gallons are the story. Chemical dosing scales with volume, so 3,955 gallons costs meaningfully less to sanitize all season than 6,981 does. Filling it once at the EPA WaterSense national average of $6.06 per 1,000 gallons is about $24 of water; the same fill on the 18ft Intex is about $42.
Several seasons: Buy-once. Built and warranted to come back out of the box for a few years, if you store it properly.

A family that will still be using it in year three
Intex Ultra XTR Frame Pool Set, 18ft x 52in
Intex
The biggest, sturdiest thing in this class that a homeowner can still put up in a weekend. It is also, by a wide margin, the most expensive one to run.
Key specs
- Water capacity
- 6,981 gallons
- Pump supplied
- 2,100 GPH sand filter
- Frame
- Galvanized steel, powder-coated inside and out
- Liner
- 3-ply, puncture and tear resistant
- Manufacturer setup claim
- Ready for water in 60 minutes

- 8.5
Overall 8.4 / 10
What works
- 6,981 gallons is genuinely swimmable for adults, not just a cooling-off pool
- Sand filter rather than a cartridge, so there is no cartridge to buy every few weeks
- Galvanized frame with inner and outer powder coating is the most corrosion-resistant construction in this price class
- Ships with the ladder, cover and ground cloth that cheaper kits make you buy separately
What doesn't
- 52 inches of wall on an 18-foot circle is a lot of water pressure — the ground under it has to be genuinely level
- Intex publishes flow rate but not wattage, so you cannot compute your running cost until the pump is in your hands
- Too heavy and too large to take down and put up casually
Skip it if: Your yard is not close to level, or you want a pool you can pack away mid-season. Nearly 7,000 gallons is not a thing you move.
What it costs to run: It is the most water in this roundup, so it is the most chemicals, the most evaporation and the largest pump. Using ENERGY STAR's own published figures for above-ground pool pumps (an ENERGY STAR model saves about $20 a year, being 11% more efficient), a standard above-ground pump implies roughly $182 a year in electricity — and that is before you scale for a 2,100 GPH sand filter running on a pool this size. Price the season before you price the pool.
Several seasons: Buy-once. Built and warranted to come back out of the box for a few years, if you store it properly.

The direct alternative to the Easy Set
Bestway Fast Set Inflatable Pool, 12ft
Bestway
Bestway's answer to the Intex Easy Set, built the same way and priced against it. Buy whichever is cheaper on the day; there is no meaningful difference in the construction.
Key specs
- Nominal size
- 12ft diameter
- Construction
- Inflatable top ring, soft wall
- Water capacity
- Varies by SKU — Bestway publishes it per model
- Pump supplied
- Varies by SKU
- Pump wattage

- 8.5
Overall 8.0 / 10
What works
- Same inflate-and-fill design as the Easy Set with the same ten-minute setup
- Frequently cheaper than the Intex equivalent, and the two are close enough that price should decide it
- Bestway publishes capacity per SKU, so you can dose correctly from day one
What doesn't
- Same exposed inflatable ring, same failure mode
- Cartridge availability is slightly thinner than Intex in most US stores
- SKU numbering makes it easy to buy the pool-only version by mistake
Skip it if: Being distinguishable from its Intex rival. If you were hoping for a reason to prefer one, the honest answer is price and stock.
What it costs to run: Identical running-cost profile to the Easy Set at the same size. The decision that actually moves your annual bill is the pool's gallons, not the badge on it.
One honest season: The cheapest setup that genuinely works for a season of real swimming. Nothing spare, nothing missing.

The consumable you will actually buy repeatedly
Type A Replacement Filter Cartridges (multipack)
Various
Buy them in a multipack before you need them. A pool running on an exhausted cartridge is a cloudy pool, and the fix is a two-dollar part you did not have.
Key specs
- Type
- Type A — the most common Intex format
- Replacement interval
- Every 2 weeks in heavy use, per Intex guidance
- Between changes
- Rinse, do not scrub
How it scoresour reading of published specs, not a test result
- Build
- 7.0
- Running cost
- 7.0
- Value
- 8.5
Overall 8.2 / 10
What works
- Type A is the most widely stocked cartridge format in the US
- Multipacks cost a fraction of buying singles
- Having a spare turns a cloudy week into a five-minute fix
What doesn't
- It is a genuine recurring cost that nobody includes in the purchase price
- Aftermarket quality varies noticeably
- Rinsing extends life but does not restore a cartridge that is done
Skip it if: Being restored. Once the pleats are permanently gray and stiff, rinsing is not saving it.
What it costs to run: The line item most people leave out of their pool budget. Count how many you use in your first season and you have your real annual filtration cost — this is exactly the number the cost-to-run guide asks you to record.
One honest season: The cheapest setup that genuinely works for a season of real swimming. Nothing spare, nothing missing.
