Lumbar support and armrests for two persons in a beautiful contemporary drop-in bathtub design. Combined with an air massage or whirlpool system, bathing can become a hydro-therapy experience reminiscent of your favorite surf spot. The bubble massage air system delivers warm air bubbles to caress your entire body. The air system takes surrounding air, heats it, and infuses it into the bath, relaxing muscles and leaving you feeling refreshed. Customize the experience by adjusting the intensity from a soothing effervescent touch to a more spirited massage.
