MTI Whirlpools new Jentle Tread™ hydrotherapy tub uses the passive resistance of water coupled with the power of full-sized whirlpool jets to provide the user with a no impact workout. Two deep, non-skid tiers are against one wall of the unit to facilitate entry and exit and provide a ledge for sitting or elbow support. The tub has 11 jets and comes with an electronic keypad. Its 72-inch by 84-inch by 41-inch deep dimensions are small enough for a home but it can also be used in commercial applications.
