H2Option from American Standard is a dual-flush toilet with jetted bowl cleaning. The siphonic toilet uses 1 gallon of water on the low setting. When the user flushes H2Option, some of the water is instantly diverted to the rim, where there are a series of chambers. The air in the chambers pushes the water forcefully out into the bowl. Combined with the force of the rest of the water entering the bowl, a strong siphon is created, removing all waste and paper. The bowl has a normal slope with a generous water spot. The H2Option two-piece dual flush toilet is available in a variety of styles that include Right Height Elongated, Elongated, and Round Front, in white, bone, and linen. americanstandard.com
