“I had three hot tubs so far, all in my backyard. The best one my Caldera Spa. Best in design because the shape of it is perfect for small space, best for comfort and also for energy consumption. I’m also very happy for a convenient price compared to my last one.”

Wished we had waited!

10 months ago
Was so excited about this hot tub, until it came time to change the water out. It airlocks every time. Being under warranty, the techs came out & took the panel off & released the airlock. I have followed every "trick" I was told to do to prevent this, & still have the same problem. Now as I'm approaching the end of warranty, & after multiple trips back to the shop to resolve this problem, I still haven't gotten answers to what the problem is. My husband & I are too old to have to take the panel off, get on our knees, use a wrench to get to where we can release the air, then put it back together every time the water has to be changed. WHAT A DISAPPOINTMENT!!! For something that was supposed to be enjoyed has now become a several thousand dollar regret. Yes, we have the option to have the shop send someone to release the airlock, but at $175 per trip...no thank you.

Customer Service Caldera Vanessa
I'm genuinely sorry to hear that you are disappointed with your spa's operation. Your feedback and concerns are important to us, and I truly appreciate you bringing this to our attention. It's worth noting that the spa model you have requires priming the pump after refilling, as indicated on page 9 of the 2024 owner's manual.

I understand that this may not make it any easier for you. However, sharing this information can benefit the wider hot tub community by setting clear expectations. If you find it challenging, perhaps a younger family member or neighbor could assist with this step, which is only necessary two to three times a year.

Thank you once again for your time and for providing your review. If you have any further questions or concerns, please do not hesitate to let us know. Our Customer Service team can be reached at 800-999-4688.

Loving our new Hot Tub

a year ago
We specifically were looking for a small spa. Not because we couldn't afford a bigger one, but we didn't want a bigger one. There are only two of us so, I don't need a 4 or 6 or even an 8-person tub. The installation was a breeze, it fits on the deck nicely, and its plenty big enough for the two of us. If I have any complaint, and it would be a nit... I'd like the tub a bit deeper so I don't displace the water out of the tub when there are two of us in it. We aren't large people! I guess this is the downside to a small tub. So far, the tub is easy to clean with the drop-in Frog cartridges and filter. We got the Ozone generator too and so, far, I'm happy with that as well.

Great for 1 person

a year ago
This was a terrific find at my local dealer! I bought it as a gift to myself, installed in a private corner of my yard and feel like I'm in heaven every time I use it! The total cost to me in northern California was around $10,000, including base installation and electrical. The ease of care is wonderful, especially if you are clean when you use the spa. The more oils on your body, the more often you need to clean the filter. I've had the spa for 8 months now. The biggest downside is that there is not a lift bar for the cover. Even though it is smaller than most covers, it is still awkward if you have physical or height challenges, and you have to create a space or stand to set the cover during use. When I was considering which small tub to purchase, the selling point for me was the alternate tub lining. Instead of the slick white tub, I chose the slightly textured Desert lining. Having a step to enter and exit is important for safety - don't skip this!

We Love Our Hot Tub

3 years ago
Thank goodness it is not a time machine! We are in our 60's. We have had 2 previous hot tubs - big ones. We decided to down-size everything a few years ago. Moved into a 1100 sq. ft. condo near the beach in St. Augustine, FL. The condo came with a approx. 15 x 30 open patio. The Aventine is perfect! Fits right into a corner with full sky views. We love to lounge and look at the stars and passing aircraft. Only downside (and it really is not) when we both are in it the water level adjusts itself. But no worries, the patio drains right into the yard. We love it. Glad we found the dealer. They were very professional with the sales delivery and the installation.
