Introducing a breakthrough in clean water
True Water™ brings the power of nanobubble technology to home spas. Trillions of oxygen-filled nanobubbles continuously scrub away contaminants⁴ to deliver clean, clear, sparkling water. These bubbles remain in the water for days, cleaning every part of your spa.

Three layers of unbelievable relaxation, plus the power of Infrared technology.
Uncover a new realm of relaxation. Leading the way with groundbreaking Near-Infrared and Red Light therapy, our J-400™ Collection hot tubs ensure a unique and deeply refreshing experience with three layers of amazing hydrotherapy.

Layer 1 – Relaxing Hydrotherapy: Premium Jacuzzi® PowerPro® jets deliver a skin-level massage to reduce stress, aid in muscle recovery, and improve your overall sense of wellbeing.

Layer 2 – Regenerative Red Light: Specialized light reaches surface tissue and cells to reduce inflammation and ease lower-back pain.

Layer 3 – Rejuvenating Near Infrared: Near Infrared light waves reach deeper to muscle tissue within the lower back to improve range of motion and provide pain relief.
