My Detailed Review & Recommendations
by Amazon Customer (5 out of 5 stars)
November 19, 2015

I've owned the hot tub for about a month now and can make some comments and recommendations others might find useful.
1. Setup is fairly easily and straightforward. Another reviewer commented that the directions are terrible, but I don't think they are. It took about 30 minutes to get everything setup and ready to inflate, then another 10 to inflate it. I don't think the manual mentions it, but place the "insulation blanket" (which is essentially a sheet of heavy duty bubble wrap) with the bubble side face down under the hot tub (and obviously before you put water in it). This will prevent rain, snow & crud from building up in the little voids between the bubbles.
2. As another reviewer pointed out, you can buy a connection for an indoor faucet that connects to a garden house (I got one at Home Depot for $7) and allows you to fill it with warm water. This is a big time saver in that you don't have to wait for the cold water taken from an outdoor spigot to warm up, especially if you're chomping at the bit to use your new hot tub. According to the specs, the tub holds 254 gallons at 80% filled. There are two lines drawn on the interior wall - "min" and "max". I believe the 80% line is the "min" line. I filled mine from my kitchen sink in approximately 4 hours. The flow rate from my sink (measured using a 5 gallon bucket and a stopwatch) was about 1 gallon/minute. I have fairly weak water pressure so others may be able to fill up faster.
3. If you don't fill the tub using warm water, you will have to wait until the tub reaches the temperature you want. The tub can heat the water approximately 2 deg per hour. So, if you used 50 deg water from your outdoor faucet, and you want the tub at 100 deg, you have to wait 25 hours.
4. WEIGHT: Do NOT put this on your outdoor deck unless it was designed for it. It might not look like it, but a filled hot tub is incredibly heavy. Water weighs about 8.3 lb per gallon, so at 80% fill height this hot tub will weigh about 2110 lb not including the people that get in it. The specs say the "filled weight" is 2701 lb but this probably incorporates four average people and is a useful design number. Most outdoor decks are built to about 50 lb/ft^2. You probably need a deck built to 100 lb/ft^2 to hold this or any other hot tub.
5. The tub can hold four average size people.
6. ENERGY: As an engineer, I'm obsessed with how things are built and use energy. I measured the current draw when it's operating. There are essentially four modes of operation: (1) circulating pump ON with heater ON (2) circulating pump ON with heater OFF (3) air pump ON (produced bubbles) (4) everything OFF. When I say "circulating pump" I'm referring to the pump that circulates water through the filters and through the heater. The bubbles are created by an air pump that pulls in outside air (which can be cold!) and out the little holes in the bottom of the tub. Note you can't run the heater with the bubbles on as it shuts off automatically. When the pump and heater are ON, it pulls about 1250 watts (1.25 kW). When just the air pump is on producing bubbles, it pulls about 650 watts. Therefore, if you have the temperature set at its max of 104 deg, you may find it running all the time with the heater on. As a conservative example of cost, at 15 cents per kilowatt-hour, you're looking at it costing $4.50 per day (24 hours x 1.25 kW x 15 cents), or $135 per month. The temperature setting is everything and I would suggest keeping it at 100 deg all the time (particularly if you live in a cold climate like I do) and if you know you're going to use it later, crank it up to 104. It will take a couple of hours to reach that. When you're done, set it back to 100 deg. Another reviewed mentioned it only cost them about $20 month. I'm not sure how that was possible, but maybe. I'm expecting mine to cost about $100 per month in electricity.
7. ENERGY TIP: Putting some kind of blanket over it during the day will vastly reduce the amount of heat loss. I stitched together two moving blankets and have been laying them over the hot tub inflatable cover when I'm not using it. I need to figure out how to put the blankets in some sort of waterproof wrapping so they can be out there in the rain and snow. Another suggestion is to find some sort of insulation (preferably waterproof) below the hot tub. The supplied "bubble wrap" liner they give you to put under it probably isn't sufficient. Mine sits on my deck (yes, I designed my deck to support a hot tub weight) and the cold air from below is obviously sucking out some heat. This is similar to the effect on bridges where they freeze before the roads do since their underbelly is exposed and cool off faster.
8. Bubbles cool the water off fairly quickly. As mentioned it pulls in cold outside air and pumps it up through the nice warm water. It's not ridiculously fast however, just something to keep in mind. I would estimate it cooled off from 104 deg to 100 deg in 15 minutes or so where the outside air temp was about 45 deg.
9. SOUND: It's very quiet when just the circulator pump and heater are running, like a low frequency hum. When the air pump is running it's about as loud an average vacuum cleaner. It's really not bad at all and you can have normal conversations sitting in the tub.
10. Educate yourself on the chemicals by reading about them online or going to a pool/hot tub store and speaking with someone who knows what they are talking about. After reading about them online, I went with Bromine tabs (over Chlorine). I bought some pH increaser, pH decreaser and some "Shock". And don't forget the pH testers (that also test for a number of other things). The chemicals will set you back $60-$100. Having the right pH, Bromine level, Alkalinity, etc. is imperative to keeping the water useable.
11. The filters clog up pretty quickly, so I would order a bunch of them just to have. Some people have said they wash theirs in the dishwasher. I have only rinsed my in the sink so far, but make sure you rinse them often. I'm not a chemist, so correct me if I'm wrong, but I believe the chemicals that are added to the water work to (among other things) bind up oils. Remember, you're essentially sitting in reusable bath water. The filters look like they get filled with a light brown sludge that must be the stuff its binded up. Keeping the filters clean is essential to keeping the tub clean and having the heat pump work effectively.
12. TIP: make sure you take a shower, and ask your guests to take a shower if possible before they get in your tub. Also, rinse your bathing suit with fresh water before you get in as detergent is usually still in the fabric and will go right in the hot tub. Eventually, you'll see lots of detergent bubbles on the surface.
13. You don't need a chair or cushion for the inside. When I was contemplating purchasing it, I wondered how people sat in it since there obviously weren't built-in chairs like a real hot tub would have. The floor is cushioned enough that it is very comfortable. You CAN buy a cushion to sit on or even for your head, but you don't NEED it. The water height is about 3', so a normal size person (I'm 5' 10") can sit in it and put their rest their arms over the side.
14. ANNOYING FEATURE: This is the single complaint I have about the hot tub. The heater & pump shut off automatically after 72 hours. I assume this is a "safety" feature, although I don't know how it makes it safer. Bottomline, you have to always check on it to make sure it's still running. Otherwise you come home from work wanting to get in your nice warm hot tub and you find its 70 deg because you forgot to reset everything that morning and it shut off while you were at work. Super annoying! If anyone knows a hack for this, please let me know.

In summary, the tub works GREAT considering its inflatable and relatively inexpensive. I'd rate the tub 9.5/10 for value and only misses a perfect score because of the annoying feature described above.

Hope this helps!

Great hot tub for a warm climate or an inside space
by Travis (4 out of 5 stars)
November 27, 2017

It is a great alternative to a "real" hot tub with some pros and cons:

Pros:

Easy to move

Assembly is quick

Runs on a single 110 outlet

Smaller and lighter weight then a full hot tub

Easy to drain the water and refill

Very quiet operation

Cons:

Heats slowly for the amount of water it is heating

Won't heat up in the cold with the top off

No jets only bubbles

Can be costly to heat

Cover not insulated very well

Plug does not fit into a recessed box.

I have grown up with a hot tub my whole life so I realize this is a great idea to have a small portable hot tub. First off it heats around 1 degree and hour which is close to typical however there is a about 1/2 the amount of water the heat then a full hot tub. I started my hot tub on my deck in the fall with temperatures around 40-50 degrees and it was heating almost constantly. There is a heating light that indicates if the heater is on and it was red (on) almost all the time. I kept the heat around 95 so it was close to ready if I wanted to use it. After connecting it to a smart plug I realized this thing was working overtime and my electric bill was going to be very high. I looked online for ways to insulate it but reluctantly moved it to an empty space in my garage as that seemed the most cost effective way to reduce heat loss. I added 1" foam to the concrete floor and put some fake grass overtop before placing the hot tub (about $55 for both). Then I wrapped the outside of the hot tub in 3/4" 2'x4' styrofoam cutting holes where the tubes go. Long story short I was able to reduce the cost of heating it from over $2/day to under $1/day fairly cheaply.

One of My Best Investments Thus Far!
by Goddesslily (5 out of 5 stars)
April 10, 2017

We were so eager to receive this Inflatable Hot Tub that once it arrived we started setting it up immediately. I'm so pleased with it I just don't know where to begin. My husband went to the Coleman website and watched an installation video. We pretty much put it together step by step watching the online video. Yes.... we had to set up our laptop outside to put it together but it was totally worth it. All in all, it took about 45 minutes to put together from start to finish including filling it up with water. Once it was filled, we let it sit for the recommended 24hrs for the temperature to reach 104 degrees. This took about a day and a half. When we were finally able to get in, we pressed the button for the jets to come on and we were totally mesmerized and i t was actually too hot! Also, when both my husband and I got in, the water rose almost to the top wanting to spill over, so my husband got a bucket and took some of the water out. I'm so pleased with this purchase I feel it was definitely worth the investment.

Awesome Product! Coleman Products Rock!
by wilsie1 (5 out of 5 stars)
May 9, 2017

Fantastic buying experience from start to finish. Item even arrived a day ahead of schedule much to our delight! Free Shipping too! Spa was easy to assemble; took us about 30 minutes before we started filling it. The spa is remarkably sturdy, considering it is an inflatable. Even if one sits on the sides, it does not have any impact or make an impression. It keeps its pressure up too (no deflating). It takes at least 24 hours for the water to reach the max temperature of 104 degrees, so don't expect to use if the first day! We figure out what time we want to spa and then use the timer to start heating the water at the appropriate time. Be sure to read up on keeping your spa healthy with the right chemical balance. The "Hot Tube Bible" available through Amazon/Kindle was also a great source of information to get us started. The bubbles are strong, effective and awesome. Friends and family are amazed by this spa. It has really enhanced our lives (and popularity)!

... for over a year now and are more than happy with it
by Arsoth (5 out of 5 stars)
June 28, 2017

We've had this for over a year now and are more than happy with it! We really wanted a hot tub but were not willing to spend thousands of dollars on one. This one is very easy to set up, take down, clean, and maintain. Very comfortably fits 4 normal sized adults. Recommend the optional chairs but NOT the optional headrests. We use a waterproof floating light show that takes 3 AA batteries and bought all of our chemicals and testers at a local hardware store. We clean the filters every few days to a week depending upon use, and change them out when they no longer come clean, and change the water out completely about every month and a half. At that time I also wipe out the interior and exterior of everything as well as re-inflate the cover and tub as needed We set ours up in mid May and take it down in Mid October. You also have to remember to reset the GFCI switch every two days since it has an automatic shut off. We let it run non stop and don't use a timer or anything. I even built an enclosure for it!

This is not a $7000 hot tub.
by Stephen Fleming (4 out of 5 stars)
April 29, 2017

This is not a $7000 hot tub.

It is a $350 hot tub. It is not as good as a $7000 hot tub. It's likely not going to last as long as a $7000 hot tub. But it's 80% as good, for FIVE PERCENT of the cost. You could literally afford to throw this away and buy a new one every year for twenty years, and still come out even.

Things that aren't obvious from the listing:
1) This unit is apparently manufactured by some entity named Bestway, then resold with other brand names on it (like Coleman; not sure if they manufacture Intex as well).
2) The egg-shaped pump connects directly to fittings on the tub, without hoses, so it needs to be adjacent to the tub. There's no ability to relocate it somewhere else. Lay out your space accordingly.
3) There are two filters inside the water that need to be removed from the tub and cleaned regularly (the manual suggests every day; your mileage may vary). Simple to do if you are inside the tub. If you forget the ritual and are already dry and dressed, you'll have to reach inside the water to remove and replace them. So you get one arm wet, no big deal. Unless you've oriented your tub so that either of the filters are against a wall or a rosebush or something. Then you have to get back inside. Again, lay out your space accordingly.
4) The user manual is *very* poor. The lawyer warnings that no one reads are in big bold print. The assembly instructions are wordless diagrams, like IKEA, but ambiguous and poorly printed (too small: we were literally using a magnifying glass). The product itself has no labeling (other than lawyer warnings) that might help match up with the instructions. And the operating instructions were apparently designed to be printed at one size, but reduced to 50% size before printing, so again, it's magnifying glass time. Frustrating. We wound up finding a video on YouTube that helped a lot.
5) There are no water treatment chemicals at all included in the box. Easy enough to buy locally or on Amazon, but it would have been nice to have a starter kit.
6) With a standard garden hose, filling the spa took about an hour. Warming the water from 80°F to 100°F took overnight.

Conclusion: it's comfortable for me to sit in (I'm 6'4"), the bubbles are nice, and it's 80% as good as a "real" hot tub for 5% of the price. Other than the one-time irritation of a poor instruction manual, what's not to like?

Great bang for the buck!
by Katherine Fulkerson (5 out of 5 stars)
September 14, 2017

This is a product that offers bang for the buck. We were looking for something portable that we could put under the awning of our patio. We live in WA State. The box arrived on time. We put carpet pad and a waterproof carpet type of material on the patio to allow for more cushion. The instruction guide was sort of easy to follow - mainly just photos, so did require some intuition to accomplish. I did the initial check to make sure we had all the parts. I was worried we were missing some until we discovered that some of them (mainly covers for filters etc.) were already attached to the tub. It took us about an hour to get ready to fill. Inflation was pretty quick. It then took about an hour to fill with water from the hose. It was a warm 85+ degree day here, so didn't take quite 24 hours to get to 104. Things we have discovered through experience: The bubble action is pretty powerful. It's noisy, but the main noise comes from the movement of the water. When we filled the tub, we stopped halfway between min and max lines. We decided next time that we would keep it closer to the min line as we sit pretty deep in the tub and when the bubbles are activated, we get splashed in the face from time to time. I am 5'6" and short waisted. my husband is 5'8". Another thing we decided is that is the perfect size for two people. Neither of us would be comfortable with a 3rd or 4th person in there, as we both like our space. When we pull the cover off, I dry the inflated inside off with a towel, as I read some reviews mentioning it gets slimy. I did order some one inch chlorine tablets (wish this order had come with at least a starter packet) and ph strips to help keep the water clean. One of the best things about it is how cushioned the floor of the tub is. It's painful for me to kneel for any length of time (knees with surgery), but, in this tub, it actually feels GOOD to kneel. They say the sides are strong enough for an adult to sit on, but honestly, I prefer just kneeling in the tub if I get too warm. The water, at 104 degrees is really warm, at least at this time of year, but will feel great when it gets cooler. We've only been using it a couple of weeks, but we love it so far...a great spend!

Year long impressions: Easy setup, working great so far.
by RainNW (5 out of 5 stars)
December 3, 2014

Purchasing a hard tub is an incredible commitment in time, chemistry, and maintenance (never mind the thousands of dollars to purchase and install). After seeing this Coleman steeply discounted on Black Friday at another retailer, I decided to give this inflatable a try.

The Coleman is a branded variant of the Lay-Z Spa, and other than color, it appears to be identical to the other Lay-Z Spa sold. However, it appears that it holds about 50 gallons more water. It plugs into 120V, which makes it extremely easy to plug and play. Just be careful what else you have on the circuit with this tub, as it *will* consume an entire 15A circuit when you take in account safety margins. I have a Kill-a-Watt connected in series so I can monitor its power consumption (more later).

The little green ovalish box is the brains of the operation. It contains the heater, a blower (which doubles as both inflator and bubble maker), and a membrane control panel. I have found it difficult to read during the day. The dark LED segments show bright white while the red is dimly lit.

Setup:

The instructions are not the best. Warnings are randomly scattered all over the place, making it difficult to read. While physically using the inflator works great, the pressure gauge is not even to the right scale needed to properly measure the correct pressure required. The first marking on the gauge is 2 psi and there is no 1 psi marking! Expect it to move a couple of millimeters and not point anything in particular when you reach 1.2 psi. The main air chamber has a very nice locking connector with a high quality one way air valve, so it is not like blowing up a pool inflatable. The sides are very firm once inflation is complete.
*Pro Tip* While inflating, its very likely the keypad will auto lock before you are done. Make sure you unlock it again ahead of time, otherwise you'll spend a minute trying to figure out why the heck it won't turn off and overinflate your pool!

There is a ground pad that looks like thick bubble wrap. There is still bits of snow on the ground, and it felt warm sitting on top of it. Although the instructions mentioned nothing of this pad, I faced the flat side down and put the pool on top of it. Do this before you put in the water!

The hoses connect up nicely and it took me a couple of minutes to finish the connection. Expect it to take an hour or two to fill up the tub with your hose. I'd imagine, the warmer the water, the better. I couldn't find my sink adapter, so I just used whatever bitter cold water came out of the garden hose though.

Operation:

People complain about how slow 120V systems are to heat up. This is because you are physically restricted by the number of watts you can pull through a typical house plug. The tub has a two stage heater and can pull between 700 and 1200 watts. It apparently decides to use full wattage if the water is cold enough. It will switch to 2 elements after about a minute from my observation. When heating, it also runs the pump. This means only 1-2F degrees an hour of warming per hour. While they made a good effort to insulate the tub, it still is an inflatable.

The bubbles are surprisingly large for just blowing air into a holed ring in the bottom. It looks just like a typical hard tub. Just remember: the amount of power required to create the bubbles takes away from the power needed for full heating capability. My tub is not at temperature yet (57F), but as it stands now, it turns off all heating in order to make bubbles.

Sound:

The heater + pump does not make much sound. Its a quiet hum, around 50 dB (or what is called a "quiet street" sound level or maybe a refrigerator hum). Obviously bubbles make a lot more noise, and there is a slight vacuum cleaner sound. But I would imagine a lot of other hot tubs have similar noise levels.

Chemicals:

You need proper chemicals in your spa. Not putting any in because its "just you" or randomly throwing in a tablet into the floater are not good ideas. You can get sick or chemically burned. The manual is completely useless and tells you to "go to a spa store" to learn about some "chemicals". Thanks guys. Just what I need is another salesmen who will try to sell me a hard tub. Searching on the internet is not much help either, as it is full of snake oil additives, unsound science on forums, etc.

Make sure you buy a pack of test strips, as blindly adding chemicals can be very dangerous. You will want to know pH, chlorine/bromine level, and alkalinity.

For the type of chemicals, there are two routes to go: Bromine or Chlorine.

Bromine is a little bit more work but has some purported benefits. It has less odor, can be restored using a shock, etc. People in our hot tub notice little to no odor.

Read the directions, but typically one will add Sodium Bromide (granules) to bring the Bromine levels up to an initial value. After that, you will likely use a Bromine tablet in the floater (1"). You will have to apply a "shock" to convert all that Bromine into free Bromine if your granules do not also include a shock.

Pick up some pH Up and pH Down. Its cheap. When I initially filled it, my water was around 6.8 (too low). My Alkalinity is slightly low as well, and usually pH Up will boost this incidentally. Your water will be different.

You can use the bubbles to mix chemicals as needed.

Energy consumption (from Kill-A-Watt):

Standby: 5-8 Watts (electronics only)

Pump: 27 Watts

Bubbles: 650 Watts

Heater: ~700 Watts with one element, ~1200 Watts both elements (automatic)

Bubbles + Heater: Doesn't appear possible
** Update - 1 week of usage **

In the Seattle winter with 40F days, this hot tub typically takes around 24-30 hours to reach temperature from cold hose water. It burns around 40kWh of electricity to heat this water up, so the initial startup costs can be costly. (40 * $0.10 = $4.00). I also noticed that it takes a lot of energy to maintain 104F (it runs 100% of the time), and you might be looking at $90 in electricity over the month! This is likely an insulation issue.
* however * I have discovered that simply lowering the temperature a couple degrees when you are not using it makes a huge difference. Backing off the temperature, to say, 100F, practically quartered the power consumption. I should have some better numbers later, but this is the way to go. It only takes about an hour to go from 100F to 104F in the worst case, so not much is lost.

We have used it quite a few times over the week, and it was very enjoyable. The tub is soft and comfortable, much more than a fiberglass or tile tub. I actually prefer it. The surround is still very firm and has not lost inflation.
** Update - 6 months later **

The inflatable vessel has developed some problems (leaks) and I have now engaged the warranty process. I am waiting for my RMA to be approved. I could not tell you if this is normal for this hot tub or not. I got my first leak on one of the seams. It was a small hole and I easily patched it. But then another developed...then another...in each case I noticed the internal ribbing completely failed. Eventually, a large section failed and it was hard to keep up with batching all of these holes as the hot tub slowly tore itself apart. These holes developed while nobody was using the hot tub. I will keep this updated with the progress on this. If the customer support is sufficient, I am not going to dock any stars on this review.
**Update: Post Warranty**

Everyone has delt with crappy manufacturers on warranties, but this company is not one of them. I had to cut out the serial number from my tub (don't be scared) in order to get a full replacement.

The new "vessel" is working geat with no issues.

I also have a comment on temperature: while low temps create long duration of full heating cycles, I've consistently kept our tub at 102-104 in the 20F range. Extremely low temps make it work harder (almost 2 days to acclamate!) but reasonable temps will hit temperature within a day.

My biggest issue with this tub is the auto shutdown. If no key presses are hit, it will turn off in 3-4 days. Unfortunately, this is the length of our Seattle rain spells. You have to babysit the console every few days. You just need to unlock it and lock it to make it happy.

This tub features an Atmel 328. I happen to be an expert at programming these. I am considering a mod but curious if anyone is interested.. WiFi or Bluetooth 4.0 is also possible.

Perfect hot tub for someone who doesn't want to make a serious investment in a proper one.
by jeff hollis (5 out of 5 stars)
January 18, 2017

EDIT: Cost analysis and advice on the bottom.

I got this tub for my fiancee for Christmas to put in our backyard on a covered patio. She absolutely loves it.

Setup is super easy, and I had it set up and inflated in about 45 minutes. Many boxes inside boxes, but not that many parts. Once inflated, it was time to put in water. Now the tricky part here, is if the water is below I believe 40 degrees, the pump won't turn on to prevent any ice from entering it or the water seizing it. So I ran a hose from my basement sink and filled it with hot water. Being that I only have a 40Gal hot water heater, and the tub is well over 200 gallons, the end result was a chilly 64 degree hot tub, but it was warm enough to start heating!

It took about two days for the hot tub to heat up to its' max temp of 104F. When I unveiled it to her on Christmas Eve, she immediately put on her bathing suit and went in it. We've been using it every couple of days since.

I live in North Jersey, so it has been very cold on some nights (down to about 10F). As long as the pump and heater stay on, the temperature stays toasty.

I've had it now for almost a full month, and there's not really any noticeable amount of air pressure change that wouldn't have been related to lower temperatures.

We keep it clean with these bromine tabs in a little floater that comes with the tub. http://amzn.to/2jzKpZF

A true highlight was a very snowy day when we relaxed outside in it with drinks in hand, and Netflix on a tablet.
-------

So after the first full month, January, I noticed on my electric bill what I had feared. After keeping this thing cranked at 104 degrees consistently (and using it a lot) in very cold temps, my electric bill was about $150 higher than it was the year prior. I decided to leave it at 99 degrees the following month, only cranking it up to 104 on mornings when we knew we'd use it in the evening. Being that it was winter, it took about an hour per degree, sometimes more. That got the bill down to about $80 over normal.

While $80 a month is steep, keep in mind that this is only a $350 hot tub, and it was the dead of winter.

ALSO: I keep reading about how the pump is crapping out on people, and they're getting errors, etc.

MAKE SURE you are not using an extension cord with this thing! If you are, make sure it is a VERY heavy gauge! If not enough power is going to the pump, it'll do one or more of many things.

DO NOT OVERFILL IT WITH AIR. There were times it was visibly low on air (especially when the temp got really cold) but it was still fine with the water in it. Definitely better to have this thing underfilled, rather than overfilled with air.

Use the bromine tabs (one in the floater will last a few days) and shock it like once a week. The water wasn't smelly or cloudy for me, and we ran it consistently for several months.

We absolutely love it. Very easy to put together. It gets very hot, and provides a great spa experience for such a great value. I agonized over which model and brand to get, and I'm happy with my choice.
