The simple and gentle oval design of this tub, with an ergonomically positioned backrest and armrests, make this a perennial classic. This bathtub can be easily dropped-in or under-mounted and can accommodate a left or right-hand installation. 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.
