The Studio® dual flush elongated toilet from American Standard is a luxury performance toilet that gives you the power of choice to help save even more water. With its dual flush options, you can select either a 1.6 or a 1.1 gpf rate each time you use the toilet. The 1.1 gpf option uses 37.5% less water than a standard 1.6 gpf toilet, and uses 21% less water than the standard models overall. A smooth, streamlined design featuring a concealed trapway coordinates perfectly with the rest of the Studio® collection, and is much easier to clean. As a standard feature, we've added our EverClean® surface to help inhibit the growth of mold, mildew, and bacteria for a toilet that stays cleaner, longer. An elongated bowl and Right Height design, this chair-height toilet stands at 16-1/2 in tall for added comfort.
