Best Home Investment Yet
Outsanding quality, very easy to maintain crystal clear water. Have had now for 6 months use it almost every day. Pumps are quiet and very powerful. Up keep is low due to the chemicals needed.

Best investment ever.
My wife and I bought this for our 44th wedding anniversary. This is the best investment we ever made. It is beyond words but just to say a few things: very relaxing, adding the audio feature was a great plus (we can listen to our favorite music while in the spa) and in the late evening, we can lay back and watch the stars as we get the warm water and gentle massaging from the spa water jets.

very happy with the spa
we enjoy it more than we thought we would and as for our friends they always offer to come over and use the spa nothing but good feed back from people that have been in it love the room is big enough for six adults to not feel like they are on top of each other,love the recliner seat has to be the best seat in the tub everybody wants it.

Our Family Absolutely Loves Time in Our Spa!!
Our entire family absolutely enjoys the time in our Caldera Spa! We purchased this as a replacement for an older tub. Our Cantabria is a huge improvement over the old tub and provides an amazing variety of jets! Thanks for creating such a great product!

Great Purchase
This new spa replaced an old one from a different manufacturer, and we couldn't be happier. It's fantastic!
Also, our dealer, Jeremy at Luxury Pools, is outstanding!
