So far, an excellent value, (year three update).
Color: Cobalt
Size: 6 Person
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.

A fabulous self care item!
Color: Cobalt
Size: 6 Person
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!

Nightmare customer service
Color: Cobalt
Size: 6 Person
The hot tub seemed great when I first inflated it. However, the first time I tried using it when it got up to temp, I noticed it had significantly deflated. I'm currently trying to exchange it for a working tub and the experience has been a nightmare. At first, I asked if I could exchange just the tub itself since the motor and cover were working fine. Nope, they require the whole thing to be returned. That's a pretty significant challenge - the tub and cover were shrink wrapped when they arrived, and since I don't have access to an industrial shrink wrapping machine, it's now impossible to get everything back into the box. I asked for a second return label so that I could send it in two boxes, but the customer service rep told me this wasn't doable. Everything must be in one box for them to process the return. I've been on the hunt for the last few days for a box big enough to fit everything. The biggest boxes at Uhaul, Home Depot, and Lowe's are all smaller than the original box. The only ones I've been able to find online that might work have to be bought online in quantities of 10 and are $110 plus shipping. So basically, I have to procure another comically sized box for over $100, or take the loss on what I originally paid for the tub. My advice for you if you buy this tub: pray. Pray that everything works perfectly when you receive it. Because if it doesn't, you're in for a painful ride.

Great Inflatable Hot Tub!!
Color: Cobalt
Size: 6 Person
This has been a game charger for my family. Originally we had an inflatable index pool from neighbors who passed it down. Unfortunately my kids wouldn't use it cause the water was always too cold. We took a chance and bought this inflatable hot tub, and couldn't be happier. We have three little ones, and this has been amazing for them to practice swimming in. They will be in there for hours at a time. This is our second season with it. It was put away from November to April, and we are back up and running for this year. This came with the Energy Efficient cover, and while it was great, it was heavy and hard to work one and off. With the inflation spot open, water got in, and there was no good way to drain it out, this compounded the difficulty of working that cover. The inflatable bladder has been great, and helps keep the pool warm. I would definitely buy this again, and reccomend for most everyone. My older child also enjoys relaxing in here after sports practice.

Pretty happy with this inflatable hot tub!
Color: Cobalt
Size: 6 Person
I've had this inflatable hot tub for almost 2 months now. We use it 2-3 times a week from Southern California. Overall, I'm pretty happy with this purchase. We debated on a permanent hot tub, but was not sure since we've never owned one, so decided on this option, and for the most part, it's been great! Here are the Good and Not Great IMO: GOOD: *Easy to set up and inflate. Took me 45 minutes to get it together and ready for water fill up. *Maintains heat pretty well with the inflatable top and cover. We use it at 102. I turn the heat off (but keep the system running) after use and in 2 days it's still upper 90's. I turn the heat on in the morning and by late afternoon, it's 102. *The Jets are powerful! *Does not come with (need to purchase separately) but the side table with cup holders is cool. *Relatively comfortable sitting against the side. My shorter wife sometimes uses the chair (purchased separately). NOT GREAT: *This takes a LONG time to heat up. Expect a couple hours for 1 degree. We keep it in the upper 90's and I set it to 102 in the morning on days I know we want to use it. By the late afternoon, it's ready. If it's at 95 and you want to use it in an hour, do not expect it to be at 102 by then. *There was ZERO direction on how to take care of the water. I expected at minimum at least a guide or something. I had no idea what chemicals to use, how much, when, as I never owned a hot tub before. Had to figure it all out myself. We ended up buying a 3 inch size chlorine tablet dispenser and electronic water reader (the tabs were useless IMO). *We bought the 6 person size, but this would MAYBE fit 6 small kids. No way 6 adults would fit comfortably. 4 adults sitting Indian style would fit okay. Glad I got the 6 person size for just myself and my wife. I would recommend this if your okay with a few of those items above. We are happy with our purchase.

Our First Hotub
Color: Cobalt
Size: 6 Person
When my wife and I met, we both wanted a hot tub in the worst way. We didn’t have very much money back then so we started a change jar called “The Hot Tub Fund.” We saved our change for 18 years and finally decided to pull the trigger. We went with the Intex PureSpa 6 person so we could have friends join us too. It’s spacious, gets right up to 104, the jets work well, and the hot tub itself seems to be well built and solid. The cover lasted for 5 weeks, but we found a small tear, which leaked water into the inner foam, which made the tear bigger, and eventually made it so heavy we can hardly lift it. I contacted the manufacturer first, and sent them all the info they asked for and they promised they would respond within 48 hours but it’s been over a week and we haven’t heard from them unfortunately. I contacted the seller, Spreetail, next. Customer service was very prompt to respond and very polite, but they said since it had been longer than 30 days the return window was closed, BUT if we returned the damaged cover they would send us a complimentary one! I explained that the cover was waterlogged and now weighed almost 100 lbs and it would cost me a small fortune to ship it and I would spend more sending it back than to just buy a new cover. I suggested paying the shipping on a new cover instead, but they were not able to make exceptions to their 30 day policy. They kindly sent me a copy of my invoice, but I had already sent my own invoice to Intex and had not received a reply. So I guess if you go with this model, just be very careful with the cover and check every square inch for defects before you use it. You should also plan on checking the plumbing connections once or twice a day because ours is finicky and prone to leaking on the hot water return valve. We lost about half the volume at one point before we knew this and have had to refill but it usually just takes a little tweaking to get it to stop leaking. It can’t be too loose OR too tight so just pay close attention. We are enjoying it, and it’s a great way to unwind after a long day.

90% of the enjoyment for 10% of the price
Color: Cobalt
Size: 6 Person
This is a great bargain for those not ready to spend THOUSANDS on a hard-walled hot tub. I went into a local pool store and asked what kind of a hot tub I could get for $6,000 or less and they basically laughed at me, so I got this instead and I've now used it for 3 seasons, including one winter with it setup in my basement and used nearly every day. If you take care of it it will last and it's hard to find any fault with a hot tub that, so far, has only cost me about $20 a month to own. So what's different about this and a traditional hot tub? Well, it has no built-in seating, which can be a pro or a con depending on what you want. I like to be able to be able to go under water and swim around a bit so that doesn't bother me that much. It also takes much longer to heat the water since it plugs into a standard 120v circuit rather than a 240v, but if you leave it on and set for your preferred temperature that should never be a problem. The only time that mattered was when I foolishly tried to charge my electric car on the same circuit and blew the breaker, didn't realize it shut the hot tub off and came back the next day ready to get in and it was cold... took the better part of a day to heat back up again. The white top of the tub is starting to stain and look a bit dingy and nothing I've tried really brings it back to a clean new looking bright white... thinking about trying to paint or stain it blue next season to hide that. There are also no powerful jets but the bubble ring around the wall is stronger than you think it would be, it really moves you around quite a bit and is really nice to have, I almost always have it on when I'm in mine. Can't really think of anything else to say about it, it's been great for the price and a big positive effect on my life. I would only recommend that if you buy this don't make the placement of it an afterthought, you should honestly spend more money on WHERE you put it than you spend on the tub itself. I built a 20x16 foot deck to put it on with a built-in mini-fridge and heated towel/clothes closet.
