Welcome to our forum.
Both Hot Spring and Caldera are made by Watkins so there are going to be similarities. As a current Hot Spring dealer and former Caldera dealer, I don't really think you can go wrong with either. The Prism is more open concept and will seat 1-2 more people comfortably than the Cantabria. The Prism has in my opinion better filtration with the dual filter vs the Cantabria only having one. Prism is salt water compatible where the Cantabria is not. I have a lot of customers prefer the saltwater, but YMMV. There is more lighting in the Prism and for me, I fit in it much better than I did in the Cantabria. Both my wife and I along with numerous customers who tried our display model floated in the lounger where in the Prism, at least my wife and I do not have the same problem.The Cantabria has in my opinion a nicer looking exterior. If you do not float in the lounger, I think it will offer better/more diverse therapy due to the UltraMassage sequencer in the lounge. Cantabria has the touch screen control panel where the Prism has the more tradition control panel with physical buttons. Pricing should be similar on both. If these are the two models you are deciding between, I would base my decision on the wet test and the dealer.
I wasn't going to be the one to mention Freshwater Salt since it hasn't been officially announced yet Both have 3 pumps. As long as you don't float in the lounger, I think the Cantabria is great. I floated and so did my wife (I'm 5'8 and she is 5'5) for reference. Warranty coverage is the same on both. Again, same parent company. Based on the last pricing I had for Caldera, I would have priced the Cantabria $500 more than what I price a Prism for.
I received a price of 12,500 for the cantabria does that seem right?
