Hot Spring vs Caldera Hot Tub
Both Hot Spring and Caldera are owned by Watkins Wellness and share core engineering. Each targets a different design language and feature mix.

Hot Spring Highlife: precision-pattern Moto-Massage DX. Caldera Utopia: open architecture with FootWell jets and Spinerelle massage.
Water Care
Both run the FreshWater Salt System with self-cleaning chlorine generation. Both support EverFresh water care with ozone, mineral, and chlorine.

Price Range
Hot Spring: $11,500 to $22,000 installed. Caldera: $10,500 to $19,500 installed. Comparable feature-for-feature.
