The EcoStrength Aspirations Chair-Height Elongated Bowl from American Standard produces a powerful, vacuum-assisted flush that uses just 0.8 gpf/3.0 Lpf when paired with the EcoStrength Aspirations tank, sold separately. Vacuum-assisted technology combines less than a gallon of water with strong suction power, resulting in a clean, clear bowl with every flush. This elongated bowl has a 17 in. (432mm) height for more comfort when sitting and standing.
