Pros and cons
Coleman SaluSpa Miami AirJet, 2 to 4 Person Round
- Best-rated tub here, with a larger owner pool than the Bestway-badged equivalent
- Smallest water volume of the three, which means the fastest heat-up and the lowest monthly electricity bill
- Round shape fits a corner or a small patio where a square tub will not sit flat
- Same AirJet system, pump and filter cartridges as the bigger models, so nothing is compromised except capacity
- Two adults is the honest number — four is only true if nobody minds touching knees
- AirJet bubbles are air, not water jets, so there is no directed hydro-massage
- Running the bubbles actively cools the water, which surprises every new owner
- Inflatable walls mean no built-in seats — you sit on the floor of the tub
Coleman SaluSpa Atlantis AirJet, 4 to 6 Person Square
- Square footprint gives genuinely more usable seating than a round tub of similar volume
- More jets around the perimeter, so the bubble effect is spread rather than concentrated
- Same pump, heater and filter parts as the smaller Coleman, so spares are shared
- Corners give you somewhere to brace your back, which the round tubs do not
- More water means longer heat-up and a higher monthly running cost
- Slightly lower owner rating than the Miami, with pump complaints the usual theme
- Square tubs need a genuinely flat, load-bearing base — a full spa this size is very heavy
- Takes up a large share of a small patio and cannot be tucked into a corner
Bestway SaluSpa Hawaii AirJet, 2 to 6 Person Square
- Functionally the same square SaluSpa as the Coleman Atlantis, from the same manufacturer
- Filter cartridges, covers and most accessories cross over between the two brands
- Frequently discounted at different times to the Coleman models, so it is worth price-checking both
- Bestway is the actual manufacturer, so parts and support come from the same place either way
- Smallest rating pool of the three, purely because the Coleman badge outsells it in the United States
- Same air-only jets, same heat-up time and same cold-weather limits as the Colemans
- No meaningful feature that the Coleman Atlantis lacks
- Bestway-branded accessories are less widely stocked in US stores than Coleman-branded ones
Decision factors
What you actually pay
Purchase prices track size rather than brand. The 2-to-4 person round Miami is $350–450, and both square 6-person tubs sit at $450–600. Because Coleman and Bestway SaluSpa models come from the same manufacturer, the two square tubs move in and out of discount independently — it is genuinely worth checking both before ordering, because the gap is often larger than any difference between them.
Running cost is where the real money is, and it dwarfs the purchase price over a season. An inflatable spa holds a lot of water, insulates poorly compared with a hard shell, and heats it with roughly the power of a hair dryer. Expect a meaningful monthly electricity bill in mild weather and a much larger one in cold weather, driven almost entirely by how often you let the water cool down. The single biggest saving is leaving the cover on and the heater set rather than heating from cold each time — reheating a full tub from ambient takes many hours.
Filters are the consumable nobody budgets for. These tubs use Type VI cartridges that need replacing every week or two in regular use, and they are the same part across both brands. Buy them in multi-packs; bought singly they add up faster than the chemicals do.
Then there is chemistry. Chlorine or bromine, test strips, and pH adjusters, plus a full water change every one to three months depending on use. None of it is expensive individually and all of it is continuous. Budget for it honestly before buying, because abandoned inflatable spas almost always die of maintenance fatigue rather than of a fault.
Which one fits you
- Two adults, small patio, first spa Coleman SaluSpa Miami Cheapest to buy and cheapest to run, best rated of the three, and the round shape fits where a square tub cannot.
- Four adults who want to sit properly Coleman SaluSpa Atlantis The square footprint converts into real seating and corners to brace against, which round tubs simply do not offer.
- You found the Bestway cheaper today Bestway SaluSpa Hawaii It is the same spa from the same factory as the Coleman square model, so buying on price is the rational move.
- You want directed massage jets Neither — look at a water-jet spa Every tub here uses air bubbles rather than water jets, and no amount of price shopping changes that.
If neither is right
- Intex PureSpa Plus 4-Person Inflatable Hot Tub (28429E) The genuine third brand in this market, with a hard-water treatment system and a fiber-tech construction that many owners rate as more rigid to sit against. See our Coleman vs Intex comparison for the head-to-head.
- Intex PureSpa Plus 6-Person Inflatable Hot Tub (28431E) The larger PureSpa, and the direct cross-shop for either square SaluSpa. Similar money, similar bubble-only jets, but a different wall construction and control unit.
Which should you buy?
Buy on size and price, because the brands are the same product. Bestway manufactures the SaluSpa range, and the Coleman-badged tubs sold across North America are Bestway spas under a licensed name. They share the AirJet bubble system, the same style of pump and heater unit, and the same Type VI filter cartridges — the cartridges swap directly between them. If you want a two-person tub, the Coleman Miami is the pick and it carries the best owner rating here. If you want a six-person square, compare today's price on the Coleman Atlantis and the Bestway Hawaii and buy the cheaper one.
Are Coleman and Bestway hot tubs really the same?
Functionally, yes, and it is easy to verify for yourself in the aisle: check the filter cartridge type, the pump unit and the AirJet branding across both, and you will find them identical. Bestway is the manufacturer; Coleman is a brand license used for the North American market. The two ranges use different model names — Miami, Atlantis, Hawaii, Palm Springs — but they map onto the same set of shells and control units.
What that means practically is threefold. Parts and accessories cross over, so a cover or a filter bought for one usually fits the other. Support routes to the same manufacturer either way. And there is no quality argument to be made between them, which frees you to shop entirely on capacity, shape and the price on the day.
What do you actually give up with air jets?
The massage. AirJet systems blow air through a ring of holes around the base of the tub, producing a wall of bubbles — pleasant, noisy, and nothing like the directed pressure of a water jet aimed at your shoulders. If what you picture when you think of a hot tub is a jet pounding a knot out of your back, no spa on this page delivers that.
There is a second consequence that catches every new owner: running the bubbles cools the water. You are pumping ambient air through heated water, and on a cold evening the temperature drops noticeably during a long bubble session. The standard practice is bubbles on for a while, then bubbles off and the heater on to recover, which is a rhythm rather than a fault.
How long do they take to heat up?
Far longer than people expect — plan in half-days, not hours. These tubs heat at roughly one to three degrees Fahrenheit per hour depending on ambient temperature and whether the cover is on, so filling with cold hose water and bringing it to 100 °F is an overnight job or longer in cool weather.
Two things change the arithmetic. Filling partly with hot water from an indoor tap gets you a substantial head start. And keeping the cover on whenever the tub is not in use is the difference between maintaining temperature cheaply and reheating from scratch repeatedly. Our page on how much electricity an inflatable hot tub uses per month puts numbers to both habits, and what temperature to set a hot tub to covers the 104 °F ceiling and why it exists.
Can you use one through winter?
Not the standard models, and this is the limitation that ends most inflatable spa ownership. Tubs of this type are not designed for use in freezing conditions: the pump, the plumbing and the inflated walls are all vulnerable, and a hard freeze with water in the system can destroy the unit. Manufacturers set an ambient temperature floor for use, and it is not a suggestion.
Realistically that gives most of the country a spring-to-fall season, with the tub drained and stored over winter. Anyone who wants a genuine year-round hot tub should be looking at a hard-shell spa, which is a different purchase at a different price — inflatable versus hard shell lays out the full comparison.
What does ownership actually involve?
More than the box implies, and this is where honest expectations matter more than brand choice. You are running a small body of warm water, which means testing and adjusting sanitizer and pH regularly, rinsing or replacing a filter cartridge every week or two, and changing the water entirely every one to three months depending on how much it is used.
None of that is difficult and all of it is relentless. The tubs that end up deflated in a garage were almost never faulty — they were abandoned. Set up a routine from week one, keep spare filters in the house rather than ordering them when the old one clogs, and the whole thing stays enjoyable. Our guides to keeping an inflatable hot tub clean and how often to change the water cover the schedule.
The bottom line
Coleman versus Bestway is not a brand decision, because it is the same spa from the same factory sold under two names. Choose the size and shape that fits your space and your household, then buy whichever badge is cheaper on the day. The Coleman Miami is the best-rated and cheapest-to-run option for two people; the square Atlantis and Hawaii are the same tub for larger groups. What you should weigh carefully is not the badge but the format: air jets rather than water jets, half a day to heat, a real filter and chemical routine, and no winter use.
