With a soft rounded edge and a stylish elliptical slipper design, this drop-in fits wonderfully in any bathroom. In addition, internal armrests and a nicely sloped lumbar support help take your bathing relaxation to new levels. 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.
