A non-lounge hot tub, the Vanto® model features the same stylish design and powerful spa jetting system found on the popular-selling hot tub Vacanza® Series.

"The lighting array is beautiful at night and the buttons which control the jets, heat, and lights are all very easy to use."

Rated 5 out of 5 by Turned our summer lake cabin into a year around retreat
For our 25th wedding anniversary gift to each other we built a patio on the lake side of our weekend cabin. After years of thinking about hot tubs we took the plunge and made the Caldera Vanto our patio's signature feature. Wow! I'm not the kind of person who typically enjoys sitting still. That changed with the Vanto. We spent hours and hours in the tub relaxing, listening to football games on the radio, gazing at the stars and watching the activity on the lake. We now find ourselves going to the cabin much more in the fall and winter so we can spend time in the hot tub. Even New Year's Eve included a sub-zero hot tub excursion. The Vanto has a great range of water pump speeds, fun accent lights and an easy to use cover. It has become a wonderful gathering point for our family.

We would not have made our purchase if it had not been for Cassidy Anderson's help out of the Clackamas OR store. Her knowledge of her product and the competition made all of the difference. She also offered us a deal that when compared to the other two brands we were considering was too good to turn down. We had an old Bullfrog tub and the massaging and comfort difference with the Caldera tub is like night and day. We would definitely recommend Caldera to someone considering a new hot tub.

Nice Tub.It was nice experience from the sale to install and use.I had an old tub that was replaced and this is soo good.Room inside the shell is great.It is the same size as my old one,but sooo much better,Lites and waterfall are a fun fit and care has been pretty easy with the canister system we use.

It is our first spa and it has been an outstanding purchase. I use it more than my wife because of a bad back, but we both have just loved it on cool or cold nights. The setting and the beautiful colored lights sets the mood. Living in south Alabama it gets quite hot during the summer months but that does not stop my getting in for all the jets and warming of my bad back after a day of golf or working in the yard.
It is very beautiful and easy to maintain after just a little home reading and working at it. We love our Spa!
