This exclusive Passion Spas massage provides an invigorating back massage, with a powerful jet that starts at the lower back and travels up to the neck. The Happy also features our Synergy Water Maintenance System, which keeps the water clear with minimal effort. Our Hybrid Heating™ system minimizes energy consumption, making the spa both a relaxing and energy-efficient choice.
