Airlock is no fun
PostedMay 29, 2025
We really like the size and comfort of our Aventine hot tub but as said by another recent reviewer, changing out the water is very difficult due to the airlock. We are in our mid 70's and it is definitely a problem getting the panel off and having to bleed out the air. Is there a valve that can be installed or something to change the problem of airlocking??
By Customer Service Caldera Vanessa, June 7, 2025
Thank you for your feedback I am glad you are enjoying your spa.
I understand the frustration of bleeding the airline at fill up.
It helps to fill the spa through the main filter standpipe however it will not always eliminate the need to clear the airlock.
I suggest working with the dealer as they may be able to assist you when you change out the water and replace the side panels.
In most cases water is changed out every 3 to 4 months unless the spa water is treated with Freshwater salt and water is changed out annulally.
Thank you for your feedback, and it will be shared with our team.
Happy Hot Tubbing!Thank you so much for your feedback! I'm truly happy to hear that you're enjoying your spa.
I completely understand how frustrating it can be to deal with bleeding the airline during the fill-up. It can be a bit tricky. Filling the spa through the main filter standpipe can help, but I know it doesn't always resolve the airlock issue.
I highly encourage you to reach out to your dealer—they're there to help and can provide support when you’re changing out the water and replacing the side panels. In most cases, it's recommended to change the water every 3 to 4 months, unless you're using Freshwater salt, in which case an annual change is sufficient.
Thank you once again for sharing your thoughts. We appreciate your input, and I will make sure it reaches our team.
Wishing you many more relaxing moments in your hot tub!

Wished we had waited!
PostedJune 11, 2024
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.

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.

Compact Hot Tub But Big Value
PostedJune 9, 2024
Easy maintenance with Frog Ease system, jets are located nicely, fits beautifully in the corner of our poolroom. It looks great and of course feels great. Perfect for my wife and I. No negatives that I can really pinpoint.

Loving our new Hot Tub
PostedOctober 18, 2023
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
PostedOctober 1, 2023
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
PostedSeptember 8, 2021
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.

Doesn’t keep the water at temperature.
PostedApril 11, 2020
Bought this and it doesn’t have enough jets to reach all parts of our body but I’d hate more because the water cools from 104 to just 98 degrees in less than 20 mins with the jets on...bummer for us!!

By Customer Service Caldera Vanessa, April 14, 2020
I am sorry to hear that you are not happy with your spa. As it turns out, your spa has an optional electrical set up. If you run the spa at 230 volts, you can run the jets and heater at the same time. The spa water will cool when the cover is open. It just depends on the outside temp and how long the spa is open as to how much it will drop.
Thank you for bringing up a good topic. The whole reason for having a hot tub is to have hot water. Taking in to account these other factors, I feel that your spa will work better for you.
