The EcoStrength Aspiration Chair-Height Elongated Toilet from American Standard leads the industry with its water-saving design that uses just 0.80 gallons of water (3.0 liters) to produce a powerful and effective flush. This ultra-low flow toilet features vacuum-assisted technology that combines less than a gallon of water with strong suction power, resulting in a clean, clear bowl with every flush. The EcoStrength two-piece toilet has a 17-in. (432mm) bowl height for comfort and easy accessibility.
