Product Technologies / Benefits:
  • Material - Acrylic: A strong, flex-resistant material with a smooth finish that is easy to clean and resists chipping and cracking.
  • BubbleMassage: BubbleMassage hydrotherapy tubs massage and soothe the whole body, channeling warm air through a 360-degree staggered air jet design. The random motion of thousands of bubbles clears the mind and relaxes muscle tension, and intensity is variable from a gentle bubbling to a vigorous massage.
  • Built-In Heater: A built-in heater maintains the warmth of the bathwater as it recirculates through water intakes and jets, allowing for a longer soak without the bathwater cooling.
  • VibrAcoustic: VibrAcoustic sound panels allow the user to enjoy music in a whole new environment, allowing the tub to resonate with high quality sound and transmitting rhythmic vibrations throughout the bathwater. On tubs equipped with Chromatherapy lighting, music and ambient lighting are choreographed. VibrAcoustic tubs come preloaded with four compositions and sync with personal media devices via Bluetooth.
