      Jet Face

      Cantabria Jets

      The Cantabria offers an amazing 74 jets that relieve-tension in targeted areas including your back, neck, shoulders and calves.


      The seats and jets have been carefully and strategically designed into a Caldera spa with a whole-body, holistic approach. Each seat or position in the spa is intended to work a different muscle group, providing a deep massage where you need it most.

      It’s the same focused, thorough circuit-training approach that certified personal trainers use to make sure you get a full body workout by activating all major muscles for a balanced fitness routine. Our Hot Tub Circuit Therapy® works those same areas, focusing on one muscle group at a time. You’re able to work on your neck and shoulders, the large muscles of your back, lower back, hamstrings, calves and feet. By adjusting the intensity of the jets, you can also control the intensity of the jets—ranging from a deep, penetrating massage to a soothing, relaxing, light touch.


      Each jet targets a specific muscle group as you move from seat to seat.

      • UltraMassage® Lounge/Seat – Gives a soothing massage to your neck, shoulders, and middle back
      • Sole Soothers® Jets – Direct a stimulating massage to your tired feet.
      • Euphoria® Jet – Provides a deep, powerful, penetrating massage to your thighs, knees, calves, and feet.
      • Air Jet System – Produces a gentle soft-tissue massage through strategically located air jets. (Utopia Series models only)
      • Whirlpool Jet – This high-volume jet delivers a powerful massage for your lower back, or a pleasant swirling effect throughout your spa.
      • LumbarSsage® Seat – Helps relieve tension and pain in the lower back with a unique jet configuration.
      • EcstaSeat® – Provides a targeted massage for the large muscles in your back. Selected models also feature jets for your wrists and/or calves.
      • Atlas® Neck Massage System – A contoured pillow cradles your neck, while independently controlled, above-water-level jets relax your muscles. (Utopia Series models only)

      Start with Clean Water

      To ensure the cleanest, softest water, use the Clean Screen™ pre-filter and Vanishing Act™ calcium remover. These two innovative water care products work especially well with the SPA FROG system to optimize water treatment. Use the Clean Screen pre-filter to ensure that fresh, clean water is introduced into your spa. Then, reduce your water hardness with the Vanishing Act calcium remover and create softer feeling water. Together, these chemical-free treatments help you experience superior water quality and extend the time between water changes.

      MONARCH® CD Ozone Water Care System

      The optional Monarch Corona Discharge (CD) ozone water care system is a virtually chlorine-free approach to water care. It reduces the need for hot tub chemicals by continuously mixing highly concentrated ozone into the water in combination with MPS and silver ions.

      FROG® Water Care System

      The FROG integrated water care system makes hot tub water treatment super simple. There’s nothing to measure or pour. Just dial in the recommended use level on the mineral and bromine cartridges and insert the cartridges into the integrated housing built into the hot tub.

      Energy Efficient Hot Tub

      With its exclusive and highly efficient EnergyPro® circulation pump, your Caldera spa is always hot and ready to use while meeting the most stringent energy efficiency standards established for portable spas. The system operates at very low wattage to filter water and actually reduces heater use since 80% of the energy used to operate it is transferred to the water as heat.
