I have one of these - different color, but same sort of thing
Super easy to put together, doesn’t take long to fill and holds the temp really well.
I had read other review where people put the foam floor blocks under it, which I did with the tarp
Is the 24” depth enough for 2 reasonably sized adults to enjoy comfortably when it’s chilly out ?
This is the one I have it’s $30 more than this model, but is 71x28, has a full warranty and freeze shield (not sure if the Woot model has it)
It is normally $749, so if you don’t mind the green (color I have) - $499 is a really great price (that is what I paid and I watched it for quite awhile)

You almost had me, Woot, until I saw photos showing that it’s FREAKING KNEE HIGH!!! And I was all set to use my TTHH coupon, too 
lol… 
Walmart sold a similar Coleman model for $250 before Christmas. 71 in diameter and 26 in depth . Last I looked it was currently selling at $348.
Coleman Bahamas AirJet Inflatable Hot Tub 2-4 person - Walmart.com
I’ve got an inflatable hot tub w air jets. It’s pretty comfortable if you don’t use the jets. Keep in mind that the air jets use air from the surrounding area. If that air is freezing cold then your water will chill down like you threw ice cubes in there.
Yes these tubs can NOT keep the water hot if it is located anywhere the ambient temperature is below 50 degrees. They are great for a heated indoor location like a garage or enclosed patio but make sure the floor can support the weight because 200 gallons plus 2 adults equals about a ton.
If you’re filling it with a hosepipe, how long would it take to get up to operating temperature?
I bought the same Coleman SaluSpa Inflatable Hot Tub linked above almost a year ago. I’m in Central Texas so it doesn’t get very cold here and when it does… it’s not for long. Mentioning that because the colder the outside air, the quicker the water temperature drops. I have mine on a screened in concrete slab patio on the back of my house - so it isn’t subjected to winds or rain and it has held up incredibly well (IMHO).
As also mentioned above, I bought some 1" foam gym flooring squares to put underneath it…and if you can - I’d highly recommend them! The tubs don’t inflate on the bottom so there is no cushioning when you sit. In our climate here it has also kept me from feeling any cooler temperature underneath as well…I actually just grabbed another set of them from here last week to extend out the padded area.
And they are labeled to hold 6 adults… and I guess you could…but make sure you REALLY REALLY like the other 5. LoL I’m 5’4" and my sister is 5’7" and it’s ok with just us… but we still bump into each other if we move around… I’d say 2-3 adults comfortably… 4 if you’re “really close” adult friends…
Back to the temperature, I set mine at 104° and on average cool nights (60°s-70°s) I can run the bubbles for a couple of sessions (whatever you call the 30-45 minutes they stay on) and the water temp will stay 98°ish and above. On cooler/cold nights the temps drop faster with the bubbles on… but the lowest it’s dropped on me is about 95° and that was after about 45-60 minutes… although I’ve honestly found that - when it’s really cold out- it’s easier to convince myself to get out of the bubble tub when the water is that tad bit cooler… makes the shock of hot to cold a little less shocking 
haha
Also… the air jets are loud! I have to put my Bluetooth speakers right behind my head and even on the loudest setting I struggle to hear clearly… part of that is my age and hearing issues (too many darn rock concerts said the ENT… LoL)… but it is something to consider
I guess the last tip I’d give is that if you have 
cats 
that go on your patio they will use the hot tub as a water bed… which is fine until something makes their claws come out… if your lucky they will usually just puncture the lid… which is annoying, but can be easily patched. But they can puncture the walls as well… so just be aware
It takes about 1 hour for every 2°… so the first fill up it’ll take a day… after that you adjust how long you leave it on or how early you’ll need to turn it on to get back up to full temp… I usually turn my off when I’m done… and then set it to turn back on between noon-2 the next day…and that gets it hot by 8pm
I put a hose connector on my kitchen sink and use the hot water to fill it if I’m wanting a quick start. Even then, it takes some time to get it hot hot unless you have an industrial hot water tank or an instant on water heater.
The fabric lid to my tub is silvered on the inside to conserve heat. It sits above the water because tensioning straps hold it down on the sides. However, if you have it outside and rain can land on it the top will fill with water and sag. I get a couple large plastic play balls and put them in the water, then put the top on. It keeps the top from filling up. With extended use you will need to replace those balls because the heat from the tub will pressurize the balls till they pop. Ultimately, I’d recommend a picnic canopy over your tub to keep the weather off it.
Finally you will need a leaf and bug net, chemicals and testing strips to keep your tub clean. Keep in mind that a hot tub is a big petrified dish for all sorts of bugs and algae. The cleaner the people are before they get in… the easier to keep your tub clean. It can’t hurt to jump on the shower first or spray off with a hose before you get in to cut down on body oils or tanning lotions contaminating the tub.
And sex in the tub? It’s great but it’s also a no-no. Plan on changing the water frequently if you do.
8 pounds per gallon of water adds up quickly! I reenforced my deck where the hot tub goes.
Also, I picked up two sheets of foam board insulation - the kind with the foil surface - taped them together, and cut a circle that fits the bottom of the tub. I feel it protects the tub bottom better than the plastic tarp the manufacturer gives you and you don’t loose as much heat through the bottom.
This is a two person (comfortably) tub and yes, the water goes up to your shoulders when seated, for average height people. I have this same one also. Believe what others have said about the temps. If you are going to have it up north, you must have it in a semi-protected , insulated, (probably need to be heated) room. We live in central FL. During the winter months, it will only run about 20 minutes or so before it drops from 104 to 99. It cannot heat while the bubble jets are running. We also have ours in an enclosed patio with insulation beneath it. This one does not have the inflatable lid, which is also helpful in holding the heat in warmer temps. Mine does not have the app/wifi connection. That’s a nice addition that the green Coleman tub mentioned above does not have.
We also added a Salt Chlorinator to ours. We don’t need to add anything but salt to the water. No chemicals. Have had it since Thanksgiving 2020 and it works very, very well.
How much electric power does it use to get and
maintain 100 degree temp…?
First question on Amazon about what plug and the power usage was discussed:
Do you need to have a special outlet?
Answer:
I was just pondering this topic myself. I read with other inflatable spas the power bill goes up roughly $15 a month. Mine went up $200 a month!! Thought the first month was a fluke, but nope…month two was even higher. I’m in a mild climate and use the spa about once a week and keep it at 95 when not in use. If anyone found a more efficient setting, I’d love to hear it. I just turned it off for awhile to see if the bill goes down. see less

No. But beware! Your power bill goes through the roof with this thing!
By Mikki… on March 18, 2021
No. It costs about a dollar a day electrically.
By RJB on March 18, 2021
It’s going to cost more to turn it down and then have it heat up again. Your better keeping it at the desired temp.
By Amazon Customer on April 3, 2021
If I were going to install one of these, I’d get some of those 4’x8’x4" sheets of blue insulation from the hardware store to insulate underneath, before the squares of soft padding.
You’ll get about 2-4 gallons per minute flow from an outdoor faucet, so divide 213 gallons by that and you’ll find that initial fill is about 100 minutes. Unless you use one of those skinny shrinkable hoses.
I didn’t have this exact model, but my electric bill did not go up $200. I didn’t even notice a change so I’m guessing about $15 would be correct. I did not leave it out all winter because Ohio sucks and no one wants to go outside then. My favorite was in the spring/fall when it was cool but not frozen.
@RebelTaz You wouldn’t want it any taller or you’d need a ladder to get into it.
I don’t own this model, but one adjacent to this brand. Had it for over 4 years. If you ever thought about making a large purchase into buying a fancy spa, buy this first. Gives you a good education on the chemicals needed and how often you need to do maintenance, which is once a week. I have run these things in the snow, big thing to watch out for is there is a 3 day auto timer, if you don’t check it at least every 3 days it will go off. If it is cold and that is a couple of hours, it might drop below temp to bring it back up. Overall, great investment for cheap fun!
The play balls and picnic canopy are a fantastic idea!
I have mine under my 2nd story deck, so I curtained in the entire area under the deck with thermal, blackout, noise reducing curtains - it has worked really well to keep a nice area outside to be able to go out to and my pups love it because they can go outside in their giant fort and lay outside without freezing.
