Such a good tub.
I’ve had this hot tub for a little over a week now. It was extremely easy and straightforward to set up. It did take about 28 hours to fully warm up to 104 degrees but that was also with it being 35-ish degrees outside. The bubbles/“jets” are very strong and it is SO relaxing to sit in. I’ve wanted a hot tub for years and was always skeptical of buying a inflatable/blow up one. Don’t let that deter you. This thing is so sturdy & you can tell it’s made with quality material. Learning the chemicals and stuff (I’m using bromide & non-chlorine shock) is a learning curve as well but I’m catching on! Trust me, and just buy it!!

A fabulous self care item!
I ordered this in 2022! I’m now a 72 year old senior female. When it arrived, I set it up all by myself. I have now enjoyed it for several years. It’s on a covered patio in Palm Springs CA area. It’s so easy to maintain and clean. Just make sure you change the filters when needed and change out water at least once a year. I use a little thing with Bromine tablets in it and shock once a week. I have noticed no electric increase as a result of it and it’s on 24/7. I have to say that I’ve purchased thousands of products on Amazon over the years and this has by far been my greatest investment. I was in it tonight and knew that I had to write a review, which I don’t do. It’s so affordable for the value you get. Good for joints. The bubble jets are powerful and quite frankly, it’s as good as the community hot tub which is right across the street from my house in a 55 plus community. I can’t say enough good things about it. I e not had a single problem with it and I e used it everyday since I got it in 2022. The cover keeps it clean even in our sand storms here in the desert! Thank you @Intex for making such a great product! Please keep the filters affordable for us seniors. PS: When I bought it, I thought it would last two years and here I am, going on 4! And, if you want company, even though it says six, it will fit four comfortably. I use it with cool water in the summer. If you want a portable hot tub, easy, affordable solution to for indoor or out door luxury that keeps it temperature and stays inflated, this is the one to pick!! Sorry for long review but great products deserve it!

Constant e90 errors on new hot tub
We used to have an inexpensive off brand hot tub which had lasted for many years and was great. After moving we purchased this hot tub as it is one of the largest inflatable ones available and we wanted the extra room. Although it's awesome when it's working, we get e90 errors constantly. The e90 error appears as an indication that water flow os restricted which can be from dirty filters or water level being too low. To be fair, we tried purchasing the off-brand filters at first but afyer getting the errors a few times we switched to the intex branded ones to see if that would fix the issue. Even with sufficient water levels and intex branded filters, we get an e90 error daily which, especiallt in the winter, will mean the pump/heat turn off and the temp will drop. The manual suggested unplugging the pump for 30 minutes to clear the code but that didn't resolve the consistent errors either. Minus the pump constantly turning off, it's a great hot tub so maybe we just got a bad pump delivered but for almost $700 I feel like it should be top-of-the-line and shouldn't be shipped with potential issues like this.

So far, an excellent value, (year three update).
This is my review of the Intex 28431EP PureSpa Plus 85 Inch. First off, the 28431EP at $678 appears to be identical to the 28431E at $1024. I contacted Intex asking the difference and their reply "They are almost the same but the little difference lies in color. And the pool kind is the same but they are different pool sets and would come with different pumps and other maintainence kit. Have a good day." If true, I can't see the colour difference. The pump it came with is labeled 2843100B, and appears and functions the same as the higher priced model. All of the extras, cover, controls, tool kit, appear exactly the same as the model without the P. If there is $300 in less value here, I can't find it. So, about the spa itself. So far so good. Everything was well designed and very easy to set up. The quality appears top notch. Filled water started at 57°f and in 24 hours, was 100°f (my initial setting). The pump/heater is extremely quiet, something I was very surprised and pleased to discover. I have had the small Intex pools before and, as I recall, the filter was rather loud. Of course the air pump is louder but not too bad, about the same level as the bubble noise itself. As for those bubbles, the strength of the massage was completely unexpected. I thought the bubbles were more for appearance, but come to find out, they work exceptionally well. Feels great on the old back. Really glad I got the 85" model, 6 person is a bit of a stretch, but 4 close friends would be doable. For my wife and I, it's perfect. The cover is very well thought out, and looks to do a great job of insulation. The inflatable bladder, give the cover a bit of a dome and should prevent excessive water pooling with rain. My take so far, is save $300 and get the Intex 28431EP PureSpa Plus 85 Inch for $678. Very happy with this purchase. If anything changes, I'll update this review. --Mark Edit: Three weeks of steady, daily, use and the spa is working perfectly. Using the La Crosse Wireless Pool Thermometer, I can see the spa cycles 102° to 104° without any problem. The heating, actually runs less than expected. Consumers tracks my monthly power, so I'll report back with details. I'm old and my back hurts so the biggest problem so far is lifting off the insulated (very effective), cover. The cover that comes with this model, extends to the ground, and is quite heavy. When lifting, the fit is snug, so you're fighting a vacuum to get it off! Easy solution though. When you go to remove the cover, undo the encircling strap, start the air pump, and the cover domes and easily lifts off! 😎 This also allows any rain water to drain off the top. Super easy. I generally take the insulated cover off for a morning soak, leaveing it off all day, using only the inflatable bladder. This seals well and keeps leaves and junk out of the water. Easy on and off makes it simple for a quick soak. I put the cover back on at the end of the day, or if we go away. When I originally fill the tub, I used a garden hose that was a couple years old, and the water was nasty. The hose must have deteriorated. Anyway, took several days and a couple of filter changes, and the pump/filter cleaned the water gin clear. Testing also showed are water was extremely hard. This unit supposedly had some method of softening water, well 8 days in, it tested perfect. With a few other standard pool chemicals, everything balanced out nicely. I check and clean/replace the filters every few days. They clean off well, especially with a bit of compressed air. You should get a fair amount of use before replacement is necessary. I also purchased the Intex 28620EP Handheld Rechargeable Spa Pool Vacuum. Maybe not completely necessary, but makes cleaning extremely easy. I think I read somewhere that the filter/heater timed out after 72 hour, or so. Not the case so far, but I use the spa daily. All said, very pleased with this spa. Stay tuned. Edit: END OF THE SEASON So, it's only mid October, but took advantage of one of the last nice days to store the spa. Read the instructions for storage, and it's pretty simple. Drained with the a hose a instructed and finished up with a wet vac, wiped down and deflated with the air pump. This work really well and collapsed the pool enough that it actually FIT into the provided storage bag! Other parts stored in the original box. Season summary: I used this spa almost daily for just shy of 6 months and enjoyed every minute. One E-90 filter error, when first installed with nasty water from an old hose. New filters and the water cleared up quickly and everything ran perfect all season. At first I was cleaning the filters, to extent there use, but found one one of them really doesn't do anything so just changed them weekly, swapping one with the other at that time. I am guessing the dual filters are a legal requirement, but for a spa this size, not really necessary. My only disappointment is the 104° temperature limit. I understand this is also a legal (or at least industry) requirement, but wish it was just a degree higher. I have a recording temperature gage and the spa consistently cycles between 102° and 104° which is good, but 102° is just a bit low for my taste. My friend has a $44,000 dollar spa and his does the same, so, I guess I can live with it. My electric usage was slightly higher than last year, but not by much. I am sure the spa accounted for some, but too little to put a number on it. As I was storing the spa and components, I had an opportunity to inspect everything. My original hope was to get a couple years out of this. I now suspect I can do much better as everything appears to be in excellent shape. Only a small amount a fading on the dark blue inner wall, otherwise all looks good. It's too bad that Amazon no longer allows replies on product reviews. Would love to compare notes with other spa owners. Summary: Absolutely an excellent value. See you next year, stay warm. Edit: Beginning year three, still good with one problem. At the end of year two, the insulated cover was finished. Started ripping at the seems. Intex does not seem to offer a replacement, so I irer the non-insulated "shorty". Actually, while not as efficient, it sure is easier to deal with. So, as a compromise, I'm happy, (see photo with shorty cover). Otherwise the spa has performed perfectly. Incredibly good deal and a pleasure for daily three (mostly) season use. Recommended.

Good to go again
Update number 2 After some help from the seller they sent over the correct warranty information. They were great help. I went through the warranty process with INTEX they did a great job helping me and replacing the pump. It took lest than a week to arrive. The hot tub is working great again.. all is good.. 4 stars just because we had a pump issue after 6 months.. but the warranty did its thing. Update 1 After 6 months the pump stopped working properly. The error 90 won’t turn off no matter what we do to fix it. Replaced filters, thermostat tried everything to fix it. I’ve been waiting awhile before I wrote a review on this I wanted to use it for a few months to see how it would do. I went in with low expectations just wasn’t sure how’d it do with just air bubbles and I was worried about the size. My wife and I are on the taller larger side. I’m 6’2 she’s 5’9. Now putting together very easy to do I put it on our back porch I did buy some pads to go underneath it just for extra cushion. The instructions are easy to follow. Just for my peace of mind I put it on its own circuit. At 120v its does take about 24hrs to heat up to 104. All that aside. This thing has surpassed all our expectations. The size is good for the two of us. Even though this is a 6 person tub it’s great for 2 large people 4 very close friends… and anymore than that it’ll be tight. The bubbles are actually great the movement is very nice. The temperature starts at 104° after running it (30min) depending on the ambient temperature it’ll go down to 101-100 sometimes 99. I’m in south Texas it’s a little warmer here that makes a difference. Our usage is every other day now for a few months. The cover We use the air up round top mostly just for convenience I did buy some quick disconnects straps I put around the handles to hold it down. The large cover works great to. It keeps the heat at 103-104° I keep the heater on 24-7 I haven’t really noticed a change it my electric bill. Think of it as another refrigerator efficiency wise. All in all you can’t beat it for the price. It’s a good size for 2 the price vs the real deal ones you can’t beat it. I was worried about the quality, it’s strong durable no issues there. Highly recommended it!

HAPPY SOAKING!
Worth the money! I was hesitant on getting an inflatable tub, but didn't want to pay 1000s for a hardshell until confirming it would get used enough to justify it. After much research, and reading many product and customer reviews, I settled on this one. I was beyond impressed at this material. I knew it couldn't be "pool float" material, but wasn't expecting what I can only describe as kevlar with air in it! This thing is no joke! Most customer reviews I read that were negative, seemed to be related to the components that hook the heater / pump to the tub. Issues such as misalignment, leaking, etc. I don't give 5 stars for the instruction booklet, and wouldn't recommend self-install if you are not super handy with these types of things. My husband can build anything with his hands, and had this installed in under 2 hours, filling with water. Everything fit and aligned perfectly. Nothing did / nor has leaked since installing in late July, 2025. Again, instruction booklet was not the best, and there was some confusion on which outlets got the filters, and which was intended for the light. Turns out, the light (we're assuming) is meant to be on the outlet (where water returns back into the tub). Not only did the light not work properly at all, it also seemed to reduce the water's ability to return to the tub, so we just don't use it. We've had a pool for years, but never a hot tub. Our first fill ended up with what we learned was biofilm. Gross, gross, gross!! We're not sure how or why, but research did mention that the factories that produce the tubs, will run water through them to ensure they're working, and possibly are not drained/dried properly, leaving behind enough to grow bacteria, that when later filled and used by the new tub owner, could introduce bacteria that could lead to biofilm. Since we had only used it once before this showed up, it's a possibility. The chemical mix took a little bit of a learning curve, but once figured out, it is now virtually as easy as the pool. We use the bromine tablets instead of chlorine, but after a few uses, I will add a bit of regular bleach just to ensure nothing "grows". So far, so good. We did end up having to drain it and scrub it after the first incident with the biofilm. This is likely my only complaint with the tub. Where the drain plug is located. I understand the bottom of the tub makes sense, but since you don't want to be moving/rocking this thing around much after set up, we had to use a shop vac to get what didn't seem like much of the last of the water out, but it was. All in all, I would highly suggest this tub to anyone looking to try one! One thing to note, since I could not find this information anywhere when I was looking, when the tub is only in its heating / filtering state, (no bubbles going), there is very minimal visible water movement. Being used to a pool with highly pressurized water being returned into the pool, we wondered if the hot tub was operating at all. Don't expect this kind of water movement. Also, the filters need to be replaced fairly regularly. I have noticed though that one always seems worse than the other, and while I always put a new one in the "worse" one, washing out the not so bad one and re-using makes it last a little longer. More than happy to answer any questions someone may have about this tub before purchasing, or after the fact. Happy soaking!

Great buy
I purchased this hot tub a week ago. I wasn’t sure how I was gonna like it because I figured it was gonna be some cheap knock off because it was inflatable. I am pleasantly surprised by how great this product is. Understanding that I live in Maine, I can only see this hot tub being used three seasons. There’s no way the small pump will be able to keep up with those cold Mane Winters. However The pump can really crank up the heat if you set it to your desired temperature about 12 hours in advance. When you take the cover off and actually use the hot tub it begins to slowly lose its temperature. So I suggest setting it high at the beginning knowing that in half an hour to an hour you’re going to loose 2 to 3°. It comes with a pillow top as well as a really intense insulated top that fits over it very snuggly. You probably don’t need to use the insulated top most of the time. It would come in handy if you have cold temperatures though. The pillow top seems sufficient in keeping the heat in under mild conditions. The picture I selected has the pillow top on it. Overall, I’m really happy with the product. It’s a way for me to enjoy a hot tub without having to pay a ton of money and have to move a gigantic tub! One thing I will tell you is get the chemicals in it right away. I waited 4 days to add the chemicals and I regretted it. It turned cloudy and slimy. I had to drain and scrub it. But once I had the chemicals right it stayed clear. Update: I’ve had the tub 3 seasons now. As mentioned, we only use it basically in the summertime. Otherwise, he loses heat too much in the winter and colder fall months. Last year we did end up getting a hole in the side of the tub, but we were able to patch it using a patch kit from Amazon and that did hold for the rest of the season. However, when we inflated it this summer, it was leaking again so we had to patch it again. so far that’s been OK and there’s been no further air loss issues. I will say that the pump can be a little finicky. We often get a code that states that there is no water flow. When that happens, the filtration system stops working and it stops heating the water. That’s kind of a bummer when you go out there expecting to use it only to find the tub is cold. I have found that the solution is keeping clean filters in the tub at all times and also cleaning all of the intake valves as well as they do get gummed up with hair. My overall opinion of this tub after owning it for over three years is that it’s a great starter tub. However, I can see my husband and I upgrading to a real hot tub in the next year or two.

Amazing hot tub for a few days. Consistent waterflow issues after 3-4 days. Can't recommend
The hot tub is super easy to set up. Heat is great and the jets are surprisingly good! The inner cover deflates pretty quickly, but it's not a big problem at all. All you have to do is give a few big breaths of air into it and it's inflated again. The outer cover is heavy duty and protects the tub completely. The light that came with it is gorgeous in the night time. Now onto the bad- After 3-4 days of ownership, use & chemical treatment, I have CONSTANT issues with the E-90 error (water flow). The big problem with this error is that when it comes up, it shuts the heat completely off, so if you've been heating the tub for a long period of time and it gets that error, you're going to have a lukewarm tub in no time at all. I've cleaned the filters multiple times, added chemicals to promote flow, unplugged and re-plugged the power in multiple times (temporary fix) and cannot fix this error from coming up. It may be that the filters need replacing, but I've only had it a couple weeks and I've cleaned the filters multiple times already, so I shouldn't have to buy a new filter every few days; THAT'S CRAZY. I'm still within my 30 day window of returning and am seriously considering sending it back because of this issue. This hot tub wasn't super cheap, so this really shouldn't be something I have to deal with ALL THE TIME. If this E-90 error wasn't an issue, I'd give this 5 stars, but I cannot in good faith give it anything above a 3, and even that might be too high because of the E-90.
