American Standard Lifetime whirlpools feature jet technology and designs that give users a more relaxing, quieter and affordable hydrotherapy experience. Jet technology generates warm air bubbles for a rejuvenating experience. The jet design makes the whirlpool easy to clean and lets users choose the type of water flow they want - from a relaxing, gentle swirl to a vigorous, deep-tissue massage. The jets are flush against the tub so users can soak without being poked. The Lifetime Drain, a proprietary horizontal overflow drain design, safely fills the tub with 30 percent more water to get the deepest soak available. Available in 5', 5 ½' oval and 6' lengths as well as a corner design. The Lifetime collection consists of whirlpools and air baths.
