Kauai Reviews

Kauai is rated 4.4 out of 5 by 120.
Rated 4 out of 5 by from Nice Spa, Great Size We sized-down from a large Sundance Cameo to the Kauai because it is just the two of us and we didn't need all that extra water to heat, and all those extra jets, blowers, etc. In fact, most of the time, we just soak in the hot water without the jets turned on. Near the end of its life the Sundance Cameo broke-down constantly, and I'm hoping that the straight-forward Kauai has far fewer problems. It holds its temp. well, and seems to use chemicals sparingly. It is comfortable for two to stretch-out (I think three would be a bit tight), even though I am 6'3". We've had the Kauai for a few months now, have used it constantly, and so-far, so-good. I love the easy-to-use gas-piston assisted cover. We looked at similar smaller, side-by-side spa models from Hot Springs, Bullfrog and Sundance, and found the Kauai to have the most comfortable seats.

Rated 4 out of 5 by from Good quality for value We have had our spa for two months and we love it. It's small enough to sit on our deck, but big enough for several people to feel comfortable. I think the only issue we would have is the day it was delivered we didn't really receive any spa Q & A session. We had never owned a spa prior to this one and there are steps you need to do to ensure the proper water quality and life of your spa. Just a short 30 minute or so, on spa ownership would have been nice!! Other than that we have survived and enjoy the benefits of our new Caldera Spa.

Rated 4 out of 5 by from Great for tired muscles and joint pain Had to have the heater board relaced at four years. Now, a couple of years later I went out to get in it, and it has stopped heating. Another service call. Out of warranty. Kind of takes the pleasure out of it.

Rated 4 out of 5 by from Worthwhile Purchase We have had the Kauai Sauna for nearly 5 years and have even transported it from the original TN home to SW Fla. I will agree with the comment in regard to Br adjustment on the built-in Frog system. I learned to plug up 1/2 of the hole on each side on position 1 and it will keep the Br level just above normal.

Rated 4 out of 5 by from Relaxation at its finest We have really enjoyed our Kauia Spa for the last year and a half. It is very easy to maintain which adds to the enjoyment. The only thing that I would add though that it is really a two person tub. That fits our needs very well as we are empty nesters with only two of us here. The water management would be trying for three adults as you would have to take out and replace every time there is a third person in order for it to circulate properly when not being used. With that being said it is a great product, the size fits our needs perfectly.

Rated 4 out of 5 by from Very Good SPA I would have rated it 5-stars, but there is only one problem in the comfort department. The jets near the head rests are not recessed enough and you can feel them in your upper back when reclining.

Rated 3 out of 5 by from troubled waters I suppose it's just because we're new to it but it doesn't seem like water quality should be such a problem. The jets are "surging" on occasion which concerns me.

Rated 3 out of 5 by from hot tub ok The hot tub is ok has a few glitches should have another head rest on the chairs. Frog system does not work all the time. It works for a while keeps bromine at the level. Then all of a sudden you have no bromine in water . Then you have to open frog system cover let it push water out of it then it works again for a few days. Not made to have inside it gets really hot at 106degrees and the temp setting is at 94 degrees

Rated 3 out of 5 by from more work than I ever thought! there seems to be some kind of white crud in the hose lines that I can't get out of there, so I change the water about once a month and in about two weeks time it's getting gross. I seem to own every chemical for spas in the world, but I can't seem to keep it clean. I'm pretty much through being frustrated with it but I love this opportunity to review it because nobody else seems to care. Thank you, Erik Rusch p.s. i've tried to work that frog system on that tub, I changed the mineral and the other thing when they're supposed to be changed out doesn't help me any with the gross water that I always end up with in tub. perhaps, this is a cry for help, but I've tried all I can do and I've been totally stressed about it in the past. I will continue the fight though, maybe I can make this tub work as it should. If caldera and the folks that sell their spas were more receptive to the needs of new hot tub owners, instead of the sell sell sell mentality,perhaps we could work this out . I won't hold my breath waiting though Thank you, Erik Rusch

Rated 3 out of 5 by from Kauai Love the size. Had an issue with the drain. It didn't work at first and the dealership had to order a part to repair it. I'm trying to figure out the chemical balance. Love the size again. It's perfect for one or two people.

Rated 2 out of 5 by from I loved my 12 year old Kauai from the past,this new one not so much. The reason I use hot-tub is to stretch my achy body each morn.This acrylic shell is very hard on my body and not as easy to slide around in the tub,as was my old Kauai. A new bromine cartridge each month,expensive.
Date published: 2018-04-26
Rated 2 out of 5 by from Quality is an issue My heater has broken twice in the 2 years I've owned it, And the jet motor has burned out as well. In addition the water drainage valve was glued shut and I had to have a service man come out and cut of the valve and replace it. They were familiar with this being a problem too. Not sure why it was sold to me with the valve glued shut. One of the LED lights has burnt out as well. Fighting the warranty to get this tub repaired required a lot of energy as well. This hot tub is not engineered well. I'm very sad about this purchase and wished I went with a Hot Springs Tub.

Rated 2 out of 5 by from Worse spa ever Bought this spa 2 years ago, after owning a Baja spa for over 10 years (trouble-free). Have spent more time "maintaining & fixing" this spa than actually USING the spa. This spa was installed, but the water would not regulate...no bromine distribution. Water discolored. "Battled" with the retailer for months, continually throwing chemicals into the spa to no avail. Finally, after begging and pleading, they sent a repair person out, who could not figure out why the spa was so discolored. THEN, Caldera informs retailer, that this spa needs a "distributer" put in the pump area (who knew? & why wasn't installed originally??). So, in essence, bought the spa & couldn't even use if the first 4 months of ownership! Tried to get retailer or Caldera to take the spa back, but no go. This resolves issues for a while, but then the circulator pump goes out. Fixed, refill spa (which each time requires removing panel door & "burping" the pump afterwards-major hassle as it requires undoing 8 screws). Following this, major "gunk" around spa. Get someone out again, now have to change filter, drain and refill. If you want a tub that is labor-intensive, this is the spa for you. I personally plan to sell it and if you are considering buying a Caldera, DON'T.

Rated 2 out of 5 by from Kauai Problem After draining spa, when filling back up, have to release pressure on the main pump to get jets to work. That requires taking the front panel off every time. That is a very disappointing part of owning this spa. I have reached out to the dealer, but can't get them to fix.
Date published: 2015-07-06
Rated 2 out of 5 by from High price low quality Paid a lot more for caldera than other brands available hoping to get better quality but I've had two service calls in less than a year. Within the first first week they had to replace the pump because it would shut down after half an hour of use. Then the temperature started going crazy shooting up to 105 degrees with thermostat set to 95. The spa still makes a thunking noise and shuts down occasionally and won't run for hours and it's still less than a year old. I would not recommend this spa to others.

Rated 1 out of 5 by from Major design flaw When you fill the spa it is not possible to avoid an airlock in the pump. This requires the tub to be dismantled so that you can access the pump to prime it - as described in a throw away line in troubleshooting. This is a major design flaw in this model
Date published: 2017-08-19
Rated 1 out of 5 by from Disappointed with a recurring problem We bought this spa about a year ago and we were very pleased with it until it was time to change the water. Every time we drain the water out, it gets an airlock. This requires an expensive visit from our spa service man to get the airlock out. The wood side panel covering the motor is not easy to get on and off. This is our 4th spa that we have owned and the first spa that has had this problem. I would not recommend this spa unless you are very handy at getting the wooden side panels off to release the airlock.

Rated 1 out of 5 by from We got a lemon and no one will help We purchased our Kauai hot tub (KAA3T1107) in October 2015 and had problems with it almost immediately. No matter what we tried, the water never looked right. We've had to drain/refill it 5-6 times already and are on our third filter. We're incredibly frustrated that this "worry-free" spa has been a total bust and are sorry we bought it! Since no one would help us, we hired a professional spa maintenance company to try and fix this lemon. Despite a thorough cleaning, all new cartridges and a new filter, we're still getting milky looking water, a strong chemical smell, and what can only be described as booger-like slime floating in the water. We haven't been able to use our hot tub when we want to as no one in their right mind would get into that milky slime-bucket. The spa guy has tried his best but hasn't been able to fix it. The one down the street looks fine, so it's not our water. We resent having to spend so much money on a brand new spa! If it's this bad new, what's it going to be like in a few years? It's turning into a useless money-pit instead of the relaxing spa we wanted. We wouldn't recommend it to anyone!

Rated 1 out of 5 by from A Lemon at Best I bought a KAUAI Serial KAA1S1060 in December 2013. My wife and I have had nothing but trouble with it from the start. The first ozoneator Caldera sent to us was the wrong one for our spa. It failed after four months and it took us three months to recover from that failure. They sent a second unit and it failed after one year. I am presently attempting to put the unit back into service and after the first refill the main pump has now failed. I would not recommend a Caldera spa to anyone.

Rated 5 out of 5 by from Perfect for Me After suffering from 2 car accidents and 1 motorcycle accident I decided to treat myself to a spa. I knew I would be the only one predominantly to go in it frequently in my family. My children are still to young to use it and my wife doesn't have much interest. With that being said I chose the Kaui model which is perfect for 1 person - or 2 (if you don't mind sacrificing jet pressure). It is great and powerful when I am in it alone - but if you are in it with 1 or 2 more people that want the jets as well you must sacrifice and evenly distribute the pressure. There are a nice amount of jets - and will equal distribution you can still certainly feel them, but not therapeutically. When I am alone I direct all of the pressure to my specific seat and they feel great. I hop from 1 seat to another and with a quick adjustment the pressure follows me around the tub. In an nutshell, the tub is great for 1 person who would like hydrotherapy; 2 people for simple relaxation; 3 people is slightly tight (a little awkward with leg room) - but all in all great for my needs. The Spa Frog also is an easy system to maintain the chemicals.

Rated 5 out of 5 by from was worth the wait I love this tub, I have had back problems for a couple of years. When I would go on vacation I would use the hot tub at the hotel and just feel great afterward. I vowed to save enough money and buy a good quality tub for myself. After saving and reviewing hot tub after hot tub I found that the Kauai had the right size and perfect location of therapy jets to fit my needs. Now after the first 4 months I can say this is the best purchase and was worth the wait. I have also saved a large amount on chiropractic services.

Rated 5 out of 5 by from enjoying our spa we really enjoy this spa. It is a 3 person spa which is what we wanted. I'm 6'5" and I fit in it very well.

Rated 5 out of 5 by from I LOVE my little KAUAI SPA! I'm in my spa at least 3 x's/week - the jets are positioned perfectly to soothe the aching muscles, relieve the stress and renew my body, mind and soul. It's energy efficient, quiet....drains in an hour, fills in an hour and heats up overnight. No complaints. Not only is the tub a product of quality but the people at Watkins blew me out of the water! They stand behind their product! They have integrity... what a concept, eh? something rare in this age of 'no accountability' in America. After 5 years in the Florida summer sun, I got a few small bubbles in the shell lining of the tub.....the people I bought the tub from came out, took pictures and sent off a claim to Watkins, maufacturer's of the Caldera Spa. Lo! Behold! OMG! can this be..??? I received a letter stating the shell IS covered under the original warrantee and I would receive a replacement hot tub. Yup! within 4 weeks, a brand new 2012 Kauai model hot tub was delivered! WOW! Thank you Watkins, thank you so much, for reaffirming my faith that all is NOT lost in the business people of America. I am so glad I chose this Caldera tub......you guys are great!!

Rated 5 out of 5 by from Big things come in small packages ! The Kauai is the 1st hot tub we have purchased and love it. The small size of only 220 gallons of water has not seen our electric bill go up very much. We have had 4 adults in the spa but typically it is meant for 3 adults as 1 seat acts as a recliner and then 2 additional seats. We have had it for almost a year and feel it is one of the greatest purchases we have ever made. We try to go in every nite. It's most rewarding after a long hard day of work to come home, grab a glass of wine or cold beer and relax in the hot tub. We would recommend everyone getting one.

Rated 5 out of 5 by from Spa Frog Problem I love the Kauai Spa. It fits our needs perfectly and is much more usable that a larger spa we had before. My biggest complaint is the Spa Frog water tratment system. It obviously was not designed for this size spa. Even at it's lowest setting the bromine is way too much. I have to continualy turn the bromine cartrige off completlely to let the bromine level come back down. At a setting of 1 (the lowest) it will climb higher and higher. Other than this one flaw it is the perfect spa. Too bad they didn't design the treatment system to go with the smaller size spa.

For three to use this spa would take a lot of water volume management because of its depth. But the depth is what makes it ideal for our use.

Rated 5 out of 5 by from Best Purchase Ever It was hard to justify the expense at first, but it was well worth it. Small size so lower energy costs and it has great features like the wrist jets!

It's like a taking a vacation without leaving home.

Rated 4 out of 5 by from 4 out of 5 Looked at many smaller hot tubs and didn't want to return to a Jetsetter we had years ago because of smaller size seats and limited jets.

We would purchase it again however wish it had micro bubbles like the Martinique offers.

Rated 4 out of 5 by from Excellent way to relax We have used hot tubs for 25 years as we find them to be very useful for relaxation and for relief of aches and pains. We needed a new spa for the two of us and the Caldera Kauai is just the right size. I do recommend buying the cover lifter and possibly a hand rail; we are an older couple. While we have only had the spa a short time, it appears to be easy to maintain. Very happy with our purchase.

Rated 4 out of 5 by from Kauai tub I absolutely love the size of the 3 person Kauai. I also love how easy it is to get in and out. However, for the price paid, I would have expected a low speed and high speed for the jets as well as the waterfall. In such a small tub, the high speed does generate significant noise.

Rated 4 out of 5 by from Hot tub for health & happiness The hot tub has been a good addition to our life from a health & leisure perspective. The tub however has had its flaws: cracked side panel, unglued jet nozzles. Our tub was delivered with one of the jet nozzles detached. Since they reglued it, it has detached 2 more times, as well as 2 other pieces. This is an inconvenience, but we have continued to enjoy our hot tub time.

Rated 4 out of 5 by from Mostly love our hot tub We have been using our Kauai hot tub for several months now and love the configuration and variety of jets. What we haven't found user friendly is the ease of water care. Our water has not been clear the majority of the time since we've started using the Kauai although we constantly adjust the chemicals as recommended and use the Frog system. Having owned two previous hot tubs, we find maintenance for this one to be the most difficult of any we have owned.

Rated 4 out of 5 by from New spa The Kauai spa fit beautifully into the spot in my backyard replacing my old spa which had gone "end of life.' we like the look, it cycles on once a day which is very efficient and the cover and spa colors are attractive. It is however a little small which can feel uncomfortable for 2 or more people, I knew that when I selected it but I didn't think the "shallow" effect of the shorter spa would be noticeable. My daughter and her fiancé visited , used the spa a couple of times also and they loved it. The jets are strong and very relaxing when you can stretch out in it. I am just know checking the water again and have yet to flush/change the water so far I am very pleased with my Kauai spa overall.

Rated 4 out of 5 by from Reasonably happy with our kauai, just wish the frog would work We got our kauai a couple of years ago now and water chemistry has been a challenge to say the least. The inline spa frog is less than worthless, it does absolutely nothing, which blows my mind because bromine will dissolve easily when you get it wet. I tried several things including creating a reserve, it wasn't until I took it out of the inline system and just dropped the cartridge into the filter basket that I got any results. And Watsons was less than helpful, I even tried to call spa frog directly, no help there either. If it wasn't for the difficulty with the chemicals I would love this tub, but as it stands it's almost more trouble than it's worth.

Rated 4 out of 5 by from Spa Frog Worthless We really like the small size of the Kauai spa, just perfect for the 2 of us. Everything works well except for the Spa Frog system. It apparently was not designed to go with this spa. Even with a setting of 1 on the bromine cartridge the bromine level goes way high. The only way I can use it all is to constantly reset the cartridge from 0 and then back to 1 then back to 0. If I leave it on 1 it just goes higher and higher. Caldera ignores my pleas for help.

Rated 4 out of 5 by from Nice spa! Enjoying our Caldera Kauai. Lots of jets, quiet and looks nice on the deck. I am almost 6'4" tall so it is a little tight in there but I knew that after the test soak. There are more than enough features to overcome the size issue ... and we wanted a smaller spa since there are only 2 of us that will use it. Have had some issues keeping the water balanced but am working on that. At times it is crystal clear and at times slightly cloudy ... and just can't seem to figure out what I am doing to cause that. One thing is to NOT use summer mode! Overall ... we are happy with the purchase though and look forward to cooler weather to enhance the experience!

Rated 5 out of 5 by from Laurel's Kauai We have found the Kauai to be a spa with excellent jets, fairly easy to maintain. Adjusting chemicals and cleaning it regularly Is work on any spa, and this is probably about as easy as it can be. We use it in the classic way, which is to relax and help ease muscle strain. Again this is probably as good as it gets. We just wish we had more free time to enjoy Laurel's Kauai.

Rated 5 out of 5 by from excellent purchase We love the Kauai hot tub, perfect size for our smaller patio. The jets are more powerful that we thought they would be based on the overall size. We have had the spa for 2 months and love it.

Rated 5 out of 5 by from Paradise Found! After an extensive search of local spa dealers and online, my daughter and I chose the Kauai for our small Huntington Beach backyard which I remodeled into a family retreat. Looks, comfort and hydrotherapy were important features in a spa, and we were willing to pay a little bit more to get the best for our project. Our Kauai spa has been in use for over a year, and we are still very happy with our purchase. Ryan, our dealer, was great with installation and startup.

Rated 5 out of 5 by from Great hot tub It is very comfortable and with two you have plenty of room. The jets are all adjustable so it will hit you wherever you need it to. It has helped my RA flares and sore muscles after working out or playing sports. I treasure my Caldera Paradise Kauai...

Rated 5 out of 5 by from Kauai hot tub We've had our hot tube for a year now. We have always enjoyed them at vacation spots, but never were sure we could afford or maintain a hot tub. However, after just going to places just to use on, it became apparent we needed our own. It was installed in a three sided glass room on our front and private deck. Since then it is used almost daily by one or both of us. After a hard day of ranch work, the aches and pains are surely reduced. We like the hot tub and serenity of the time spent in the hot jet focused water, that we are now adding a separate bedroom entry to a new 'only' hot tub room. It has become such a part of our life that when we travel we cannot wait to get home to our private retreat. This has been one of our best investments. I am sure there is a Caldera Spa to fit any persons needs.

Rated 5 out of 5 by from Great investment for health and comfort We have had our Kauai hot tub for three years now and have enjoyed it every time we get in to relax. There is nothing better to relax tired muscles and relieve my arthritis pains. This saves me from going to expensive spas. My wife and I use our spa time to converse and enjoy bonding time. This is much better than the motor home we sold to buy this spa.

Rated 5 out of 5 by from Kauai spa we love our kauai. Built for 3 but big enough for 4 comfortably. we love the changing colored lights plenty of glass rests. Can't get over the temperature controls: you can keep it cool in summer but with a push of a button temperature quickly rises. the only problems we've had is maintaining pH alkaline balance, and sometimes mildew builds up on the cover and needs to be cleaned with bleach. It is a dream on our new enclosed porch.

Rated 5 out of 5 by from Why didn't we do this before? This is our first hot tub and we are wondering why it took us so long to get one! The smaller size is perfect for the two of us and it's located just outside our bedroom door, so we can slip in for a quick dip when it's cold outside. We will probably drain it next spring and not let water sit in it over the summer, but we are looking forward to some cool fall nights. It's easy to take care of and we couldn't be happier.

Rated 5 out of 5 by from Excellent after fixed We have enjoyed our spa except for the three months we were unable to use it. The reason for that is that Caldera provided the incorrect ozone generator for the spa to the dealer and when it died it left us with an absolutely useless spa until the dealer went through a three month cleaning process to remove all of the detritus that had clogged the entire piping system, the pumps, and the spa itself. Once they installed the correct ozone generator and cleaned the spa thoroughly we are back to total enjoyment.

Rated 5 out of 5 by from I really like the jets This hot tub really has perfect jets. Its comfy, easy to maintain, and just a very nice hot tub. We had to go with a smaller tub because of our zoning, but there are some drawbacks to a smaller hot tub. It's much less energy efficient than a larger tub- our electric bill went up about $50 in the summer and $100 in the winter. And while it seats 3, its really only comfortable for 2. If I had to do it again would go back and buy a house that they would let me put a big hot tub in, but If I couldn't I would buy this one again in a minute.

I also have back problems and since I bought this spa I have eliminated trips to the chiropractor. My mother also uses it to relieve pain in her hip. Overall very pleased and would recommend a caldera spa to anyone.

Rated 5 out of 5 by from Worth Every Penny We looked at a lot of other brands that were much less than what our Kauai cost but it was worth it.

Rated 5 out of 5 by from We love our Kauai spa! Love our Caldera Kauai spa! Just big enough for the two of us. Love my lounger and choice of deep seat or high seat. Easy to maintain, energy efficient we feel. Have owned for 3 years and it just sprung a leak. Dealer had to be "sat on" by factory to get it repaired as it is still under warranty. Was without my spa for two months as my spa repair took a back seat to dealers more important pool customers (typical of dealers here in the NE) but we have it back now and it appears to be working fine. Hope it gives us many more years of enjoyable use. Love to use it best in the wintertime. Something about clear cold air (30's), snow on the ground and hot water really is a relaxing experience.

Rated 5 out of 5 by from Excellent Purchase Though we have a large plot the area where we wanted the spa is quite small and was prepared for a spa this size, along with the utilities present at the location. To have prepared another area would have been cost prohibitive. With only two adults living here the larger Tub would have been space, preparation, and efficiency wasted. I hop to get many good years of use from this purchase,

Rated 5 out of 5 by from Colorado Mountain Home This hot tub is probably the best I've had, I've had Wind River and Sweetwater spas as well as an old Jaquzzi and this is a step above! I was reading the reviews online and I have to tell you my spa is a 2002 model and I have had zero issues with it. It has been moved twice and it still works as it did when I first bought it, I'd buy another in a heartbeat....in fact I may have to because we're thinking of moving to Oxnard CA in the next few months and we don't want to move it again!

Rated 5 out of 5 by from Great Hot Tub This is my second caldera spa, my first one located in my last house lasted over 14 years with no problems. The Kauai, is perfect for 2-3 people. I recommend getting the ionization kit, keeps chemicals lasting longer, Also get the from spa kit which are two chemical products that auto dispense, reducing 90 percent of having to frequently add chemicals. I researched and viewed many of the competitors and Caldera used higher quality parts. Also note that they use Watkins Johnson motors also used by Hot Springs Spas. My new house came with a Jetsetter Hot Springs spa and after 16 years the motor gave out. I looked at the latest Jetsetter and it still only had 17 jets vs 31 jets in the caldera AND the Caldera was about the same price!

Rated 5 out of 5 by from Terrible Buying Experience My wife and I just purchased our spa. So far we really like it, however the buying experience has been aweful! Your videos show ease of water maintenance, but our spa came without Frog system. The manual comes with an addendum telling you that it should be included. Dealer sends box of chemicals and tells us this is better. If you want the Frog system we'll sell it to you, but it's more expensive and it smells. So we don't know what we are supposed to be doing.

Rated 5 out of 5 by from Really enjoyed the spa during the Michigan winter months. Heavenly when snow is everywhere. Placed the spa in an outdoor covered patio, so no snow to clear off the cover, but the cold fresh air was an amazing counterpoint to the bubbling hot water jets and light show.

Rated 5 out of 5 by from Happiness turned to disappointment I loved our Kauai at first. So comfortable and seemed so perfect for the two of us. Three months down the road, I'm so over trying to get the water to stay clear. I heard a rumor that some of the spas on the market today have changed the source of their plumbing and that the new plumbing has a problem that causes white flakes in the water. The water turns a milky white when the jets are on and it gets a bit too foamy. I was told to purge the system with a product called Ahh-Some. I did that 3 times the first time, rinsed it twice then shocked the fresh water with spa grade hydrogen peroxide. This process took 10 hours of my day. The water stayed nice for about 9 days, though the milkiness of the water with jets on returned at about 5 days. On the 9th day, it all began to go downhill. White gunky stuff began to grow rapidly inside the plumbing and would shoot out when the jets were turned on. I have just purged it for the 4th time with Ahh-some. Ran the jets for 40 minutes, then let the tub sit for 8 hours and ran the jets for another 30 minutes before draining and cleaning. I will fill and rinse the tub twice before doing a final fill with filtered water. I thought spas were supposed to bring relaxation and peace to one's life. Mine has been a source of frustration. If this attempt fails, I think I'll have to ask for my money back. :-( I waited so long for this tub! I have attached a photo of what is coming out of the plumbing.

Rated 5 out of 5 by from Still think it was the best decision we've ever made. Great decision. My husband has had back surgery and he and I often do more than we should and after a sit in the hot tub we find the relief we are looking for. There are two seats and a lounge seat all of which have jets that will massage different areas of the body including wrist jets in one of the seats armrest which really relieve carpul tunnel, which I suffer with. It's amazing!! The Kauai model was small enough we could put it inside the house in the basement. We are older and didn't think we would use it as much if we put it outside. For us that was a good idea. It is very economical to operate. I would suggest this model for anyone who was looking for a beautiful hot tub with all the features but a smaller model, Absolutely love it!! We have had ours Kauai now for a couple of years and have absolutely no problems. If you are looking for a fantastic hot tub in a smaller package this is the hot tub for you.

Rated 5 out of 5 by from Great spa for 2 people With only 1 pump for this spa, you will have to choose which jets to activate if you want full power directed where you need it. If you are ok with that, this is a great spa. I use this spa 3 or 4 times a week in the evening to massage my leg muscles after a long run. I had to be creative to get the powerful jets to hit right where I need the massages but now (after a couple months of use), I have found the right settings and sitting positions (not always how the seats are designed) for me. I massage my calves, front/back thighs, back and neck using 8 different positions The low profile makes it very easy to get in/out without a step and makes the spa less intrusive in the backyard. It is also much more quiet than other brands in stand-by mode which is great. I recommend this spa as a 1 or 2 people spa.
