Caldera Spas Review

Caldera Spas is a good hot tub brand, but it has several fewer options across its three product lines than every other manufacturer we reviewed. The company offers 15 spa models that range from the small, triangular Aventine to the behemoth Cantabria, which seats eight.

Our Verdict

Caldera Spas is a good spa brand, but it does not have as many hot tub models or extra features as other brands.


  • Caldera spas offer saltwater sanitation and in-line sanitation systems.


  • Caldera Spas had the fewest number of hot tub models of the brands we evaluated.
