The circular Japanese-inspired drop-in soaking bathtub is a bathing enthusiast's dream. Deep, ample interior space and an internal seat for comfort make for a pleasurable soak. 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.
