The 8 Best Inflatable Hot Tubs
Updated by · How we research
Eight blow-up hot tubs from Intex, Coleman, Bestway and CO-Z compared on real seating, heat-up time and winter use. The Intex PureSpa Plus leads for groups. When users buy our independently chosen editorial selections, we may earn commissions to help fund the Wiki.
The seat count on a blow-up hot tub's box is generous: a tub sold for four holds two or three adults in comfort, so most buyers should size up. These spas plug into a grounded outlet and warm slowly, about a degree or two an hour. They suit anyone who wants a backyard soak for a fraction of a hard-shell spa's cost.
Editor's Notes
October 23, 2026, by Ezvid Wiki Admin:
The Intex PureSpa Plus keeps the top spot, now sold as a set with a thicker foam cover, because it gives a group the firmest walls and a built-in water softener at a fair price. The Coleman SaluSpa returns in its current form as the Coleman SaluSpa Miami, and the square Coleman SaluSpa Hawaii stays. The Cosyspa Luxury Outdoor and the Galvanox Portable Blow Up are gone, since both come from little-known sellers with thin records, and the round Bestway Hawaii is no longer offered.
The new picks cover a big family, a small patio, a stylish round tub and two budget choices. Nobody has lab-tested these spas, so we built the list from Intex and Bestway manuals and FAQs on heating and cold weather, two long-term owner write-ups of a Coleman tub, pool-forum threads that track pump and liner failures, and the 2024 federal recall of Bestway spa pumps.

While the big name brands like Coleman and Intex continue to offer some of the best options on the market, some lesser-known brands have struggled to remain relevant, especially with some significant durability issues like the ones seen with the now-removed Aleko Oval. That model had a pump that tended to fail after one or two years, making it a pretty lousy investment despite some nice features.
If you stick to the big names, you're going to have a fine time with durability, but there's still a matter of capacity to consider. A model like the Coleman 90454 SaluSpa Hawaii might last a long time, but it's limited to 177 gallons, which is a bit small for four people to enjoy. Something like the Bestway Hawaii, by comparison, offers 222 gallons. That's more than 55 gallons per person compared to the Coleman's measly 44. But the Intex PureSpa Plus offers the best of both worlds, with a 210-gallon capacity in its four-person model, and a 290-gallon capacity in its six-person model, all while boasting a high degree of durability.
One last thing to scrutinize with these tubs is their air jet quantity and positioning. A lot of air jets might give you a nice jacuzzi experience, with a relaxing massage from all those little bubbles, but oftentimes the air from those bubbles can be a lot colder than the water, and too high a bubble count could actually decrease the water temperature. I might be a bit biased as I'm a much bigger proponent of still water in a hot tub, but if you're deploying your tub in a cold environment and you want those air jets on full blast, you might also want to look for a model with fewer jet openings.

We wanted to create a list of inflatable spas that would ensure buyers didn't feel they were missing out by skipping the more expensive permanent Jacuzzis. Durability was a top priority, which is why the MSpa M-113S caught our attention, with six layers of PVC material in the walls. The Coleman SaluSpa should also last a long time without showing wear and tear, as it features I-beam construction — a special build that resists force and shouldn't bend. We understand that, for some, Jacuzzi time is social and for others it's private. That's why the large Gymax Outdoor and the Goplus Six-Person made the list, both of which should be able to accommodate a small party, but the Aleko Oval also snagged a spot for those who just like to soak solo, or with one other person. There's no need to sacrifice style just because your hot tub features air-filled rather than concrete walls, and the MSpa M-113S, with its eye-catching design, proves that. Everybody appreciates the little perks that make hot tub time even more relaxing, so the Intex PureSpa Plus caught our attention, with its included headrests. The Aleko Oval also has a thoughtful addition in its beverage holder.
How Many People Really Fit
A good rule is to take the maker's top number, subtract two, and buy for that.
Treat the seat count on the box as a party maximum. A tub sold for two to four people is about six feet across on the outside, and the thick air walls leave a much smaller pool inside. Family Handyman's writer spent two months with a Coleman SaluSpa sold for four and found it fit two adults, and RosenBerry Rooms reached the same verdict after six months (RosenBerry Rooms). A good rule is to take the maker's top number, subtract two, and buy for that.
Shape matters too. Round tubs give everyone the same curved backrest. Square tubs, like the Coleman SaluSpa Hawaii, give corner seats, and octagons tuck into a patio corner. Check the inner size where the maker lists it: the Intex PureSpa Bubble Deluxe is 71 inches outside but only 51 inches inside.
Plan the spot before you buy. A big tub holding about 300 gallons weighs around 2,500 pounds with water alone, before anyone climbs in, so it needs flat, level ground such as a concrete pad or compacted soil with a ground cloth. Most wooden decks aren't built for that load; ask a builder before you set one there.
Heating, Winter Use And Running Costs
Inflatable spas heat slowly. Their plug-in heaters are small enough to run on an ordinary 120-volt circuit, so a fresh fill gains roughly 1 to 2 degrees Fahrenheit an hour, and the first warm-up from a cold hose often takes a full day. Spa Depot, a hot tub retailer, warns that some tubs manage a degree an hour or less in cool weather (Spa Depot). Keep the cover strapped on whenever the tub is idle, and use the timer to heat only before you plan to soak.
Bubbles cool the water. The air pump blows outdoor air through the floor ring, so a long session with the bubbles on drops the temperature and makes the heater work harder.
Winter use is possible but costly. Bestway's freeze protection turns the heater on to keep the pump and liner from freezing, which protects the tub but adds to the power bill. Coleman says not to run the Sicily when the air is below about 39 degrees. In cold regions, many owners drain and store the tub for the winter. Budget for chlorine or bromine, test strips and filter cartridges that need rinsing every week or two; RosenBerry Rooms put its first-year extras at $300 or more.
Safety: Power, Heat And Children
Plug the pump straight into a grounded outdoor outlet, never an extension cord. Intex builds a ground-fault breaker into the plug; press its test button before each use and never bypass it. If an outlet keeps tripping, have an electrician look at the circuit.
Keep the water at or below 104 degrees Fahrenheit, the limit every maker on this list sets. The U.S. Consumer Product Safety Commission warns that hotter water can cause drowsiness that may lead to drowning (CPSC). Shorter soaks and lower temperatures are safer for kids.
A hot tub is a drowning hazard for small children. Inflatable spas come with a cover that clips or straps on, but it is not a safety barrier. Keep it locked whenever the tub is unattended, and never leave children alone in or near the water. Some towns treat a filled spa like a pool and require a fence or gate, so check local rules.
Check recalls on any older tub. In 2024 Bestway recalled about 866,000 AirJet and HydroJet pumps sold with SaluSpa and Coleman tubs from May 2021 to May 2024 because they can overheat and catch fire (CPSC recall). Owners of an affected pump can get a free replacement.
How we researched this
We compared 16 inflatable hot tubs from Intex, Bestway, Coleman, CO-Z and several smaller sellers, and read the makers' specifications, manuals and FAQs for the eight finalists. We studied long-term owner reports from two hands-on reviews and pool forums, and checked every brand against U.S. Consumer Product Safety Commission recalls. No lab has published comparative tests of these tubs. Updated October 23, 2026 by Ezvid Wiki Admin.
Frequently asked questions
Are inflatable hot tubs any good?
Yes, for the money, with limits. They give a warm bubble soak for a fraction of a hard-shell spa's price and need no electrician, but they heat slowly, use air bubbles rather than water jets and tend to last a few years rather than decades.
How long do inflatable hot tubs last?
Expect a few years. Pool-forum owners report pumps and heaters failing within a couple of seasons on some tubs, while others keep one going for years by draining it in winter and storing it dry (Trouble Free Pool). Brands that sell spare pumps make repairs cheaper.
Can you use an inflatable hot tub in winter?
Some, with care. Tubs with freeze protection keep the pump and liner from freezing, but heating costs rise and makers set limits, such as Coleman's warning not to run the Sicily below about 39 degrees. Keep the cover on and expect slower heating.
How many people fit in a 4-person inflatable hot tub?
Two adults fit comfortably, three at a squeeze. Buy a size up from the number of adults you expect to soak together.
Can you use salt water in an inflatable hot tub?
Only in models the maker says are saltwater-ready, such as some Intex PureSpa sets used with Intex's saltwater system. Salt can damage pumps and heaters that aren't designed for it, so check the manual first.
