Rated 5 out of 5 by Love the 2-Person Spa!!!! WE love this Caldera spa; it is small, yet roomy, and fits perfectly on our back lanai. Every evening we go and soak, then turn the jets on and get the perfect massage. It is easy to keep clean and our electric bills stay low. We had purchased larger spas in the past, but this one is ideal and would recommend it highly to anyone asking. It has a beautiful design and we even have steps that fit perfectly with it. The top is light enough for one person to open and close and will definitely recommend to friends & family. Already have. It is the best overall spa we have ever owned. You cannot believe how roomy it is for the size and the features are great. Comes with lights and spots to hold drinks. Cheers!!!! July 7, 2015
























































Rated 5 out of 5 by Slice of Heaven I am retired so I get in my Hot Tub every morning. AAH!!!!! I get to relax and soothe my aching back. My favorite thing is to lie back and plan my day. The only thing I miss when we go on the road in our RV is my Aventine Hot Tulb! June 24, 2015
























































Rated 5 out of 5 by Our hot tub for two We were looking for a hot tub to fit on our small outside deck. The Aventine looked like the answer a year ago when we were looking, and now after a year's use we're sure it was the best unit to buy. One thing we weren't sure of was hooking up the Aventine on 120 volts but it was the only electric outlet that was available when we had the unit installed. But after going thru an extra cold Tennessee winter (many days we used the hot tub, the temp didn't get to 20 degrees F), we were very happy how the hot tub held steady at 104 degrees every time we used it. We are very happy how easy it is to use and maintain the Aventine and we would recommend it to any one who is looking for a hot tub for two.

Rated 5 out of 5 by Aventine is a wonderful spa. Great small spa; very comfortable and easy to maintain. I've used daily for 3 years without any problems. I extended the drain hose outside the cover for ease of draining. I would add a couple more jets around the hip and knee areas.

Rated 5 out of 5 by Love our little spa! My husband and I had been wishing for such a spa to soothe our tired muscles and yet be affordable for us. Since we're avid DIY-ers, we often find ourselves with sore muscles after a weekend push either in the house or in the yard. We love our little spa -- it's just right for the two of us. My husband is well over 6 foot and has no trouble getting comfortable. We definitely would recommend this spa for a single person or a couple -- no matter the age!

Rated 5 out of 5 by Great Little Hottub Perfect size for 2 people. Great customer support. Easy to care for by a single woman. September 8, 2014
























































Rated 5 out of 5 by Awesome! Great spa for small spaces! Very easy to maintain and enjoy. Just be aware it is not a plug and play you will need to have a dedicated 30 amp circuit to plug it into. The spa frog system is great and regulates all chemicals for you, just replace cartridges and jump in and relax. I will say that I have a 6' 2" son who is very comfortable in the unit and able to stretch out. Would definitely recommend purchasing this spa, great value for the money.

Rated 5 out of 5 by Enjoyable hot tub We bought our spa after my husband's knee replacement and we have enjoyed using it since then. Our grandchildren also love to use the tub and we have all spent many pleasant hours in the spa. September 6, 2014
























































Rated 5 out of 5 by Great spa for Couples We have had 2 spas previously and they were the large ones, measuring about 8 x 8. We like this smaller one better. It is quiet and a lot more economical to run. The jets can massage just about any body part and it is amazing the comfort and relaxation we get from the spa. Would highly recommend this to friends and family. September 5, 2014
























































Rated 5 out of 5 by Just Plain Great I sometimes awaken in the morning very stiff and tight. I am retired and like plain golf early. I have been using the tub in the morning to help loosen my muscles and joints. This has been a great boon to my game and to my overall sense of well being. It is the perfect size for me and the cost to run it has been minimal. I would highly recommend it September 5, 2014
























































Rated 5 out of 5 by Aventine It is the perfect hot tub for two people. I really enjoy it. The care system is easy but I think it is costly. The Bromine cartridge doesn't last long enough. thanks, Gary September 4, 2014
























































Rated 5 out of 5 by Aventine Hot Tub My wife and I looked at a lot of different hot tubs to meet our needs that included size to fit into a small space. We found the Aventine hot tub and realized it was the deal. I am 6'3" and fit comfortably in the tub. If you are looking for a two person hot tub, this is the one.

Rated 5 out of 5 by Excellent purchase I purchased the hot tub a year ago and I have used it almost daily since. The small size is perfect and it doesn't take up much room. Because it is small it is easily drained, cleaned, refilled and heated in a matter of a few hours. September 4, 2014
























































Rated 5 out of 5 by Great Spa For a Small Space I've owned my Aventine for about five years. Comfort: Plenty of room for two to stretch out. Quality: No issues that have required any repairs. Ease of Water Care: Once I figured out the optimal setting for the bromine cartridge relative to my water supply, it's been really easy. I test, shock, and make any needed minor adjustments once/week. Energy Effiiciency: Outstanding. Barely noticeable impact on electric bill, even during the winter (coastal North Carolina). Value: A bit pricey relative to the size. But there aren't a lot of choices if you need something that fits in a corner and leaves space to walk.

Rated 5 out of 5 by Perfect! This spa is just right for two people. It fits very nicely in the corner of our sunroom. Easy to care for too! September 4, 2014
























































Rated 5 out of 5 by Great little spa! Great little spa ! Easy to take care of and clean. It's small size make it perfect to put anywhere. September 4, 2014
























































Rated 5 out of 5 by Powerful jets...Practical design! I love my Caldera Aventine hot tub. Not just like...love. It is so well designed! Getting in and out is easy (I got a stone step), but moving from one seat to another is super easy with the well placed handle. The sit up seat has jets that penetrate to lower back and still your feet can get a massage from the foot jet. The lay back seat gets your upper back plus you can massage your legs with the powerful jet from the side. I had a Jacuzzi brand for years before this hot tub. The jets were never as powerful. I had to have the spa technicians out once or twice a year and great cost. I have had this tub for over 4 years...not one service call! Yep, I LOVE it!

Rated 5 out of 5 by Great addition to our home We have had the spa about 2 weeks so can't comment on the power usage, but we find it relaxing. The BIG problem we are having is that I shut it down for maintence and now it wont restart. The control panel lights up then flashes "Ready" with 5 -----.Cant get any help from Caldera and still waiting for the sales rep to get back to me. When it is working it is great, but if I am going to have hassles everytime it requires maintenance, then it sort of negates the relaxment we get in it.

Rated 5 out of 5 by Convenient and comfortable Love the Aventine! Fits nicely in a corner of the house and we don't have to go outside! The jets are great on the back and the seats are comfortable. Low maintenance and easy to use inside. April 8, 2013
























































Rated 5 out of 5 by Exceptional spa experience Fantastic spa for 1-2 persons! Super easy to maintain and cost efficient to heat. We have owned this spa for 1 year and use it 4-6 times a week for about 45 minutes per session. We love it so much we are considering trading up to a larger unit for more seating options. April 8, 2013
























































Rated 5 out of 5 by Nice Spa This size is excellent for my wife and I. We use to have a four person but this is much better. Fits in the corner of our sunroom with ease. Love it!!! April 8, 2013
























































Rated 5 out of 5 by Great Hot Tub Well worth it. Easy to set up and maintain. I highly recommend this model for its portability and its ability to move when you need to move. Big fan. January 17, 2012
























































Rated 5 out of 5 by love it! This is perfect for the my husband and I. Easy maintenance - I can do everything myself- it is easy enopugh for one person to handle as far as getting cover off and cleaning, adding chemicals, water etc. thanks to Treat's Pools and Spas if we ever have any questions or need supplies they are always ready to help!

Rated 5 out of 5 by Love Our Aventine............. Bought our Aventine a little over a year and a half ago and it has been the best hot tub we've ever had. August 30, 2011
























































Rated 5 out of 5 by So Easy Even I can Take Care of It Our Caldera Spa is not only extremely dependable it is also amazingly easy to maintain and care for. This is a quality product with a capital Q. May 26, 2011
























































Rated 4 out of 5 by My Tub I'm satisfied with the hot tub except for the circulation pumps coming on so often when its not in use to keep the temperature from between 101 and 103. Seems like a big waste of energy to me. September 8, 2014
























































Rated 4 out of 5 by Great Hot Tub Great product. Helps reduce my lower back pain caused by arthritis. Water can be tricky to maintain. September 5, 2014
























































Rated 4 out of 5 by Perfect sized tub for two We have owned our aventine tub for about 2 years now. And are still enjoying it about 3 days per week. In the summer we turn the temp down to 99 and it's the perfect temp after sundown. The only thing I would add is more jets but what spa owner doesn't say that:) September 4, 2014
























































Rated 4 out of 5 by Have used my Aventine Tub for 1 Month Now I ordered the tub in a coastal gray but it appears more like a tan color with light streaks of gray in it. The tub is great for 1 person especially. Although it says it has 2 seating arrangements, with the buoyancy, you can comfortably move in many positions to relax. That surprised me. The jets provide a lot of power but when on full strength, it gets quite sudsy and I have to turn it down. I don't know why that happens. The men who delivered it were more "pool people" and really couldn't explain how the control panel works. Although it's small, it's involved and I'm still confused as to how to operate it. I'm also a bit confused as to the number to put the bromine and minerals on but with it being a small tub, I'm told not to really be too worried about it. All in all, the tub is quite nice and attractive on my deck. August 5, 2014
























































Rated 4 out of 5 by Very relaxing I purchased this hot tub to help deal with the pain of arthritis. It has help, pain has been greatly reduced. Only concern was the Frog system, had a hard time getting the bromine level stabilized, switched to chlorine. April 16, 2013
