The Titan Chair Height toilet features a space-saving, round front design that fits perfectly in smaller bathrooms. The chair height design from American Standard is a taller, more comfortable toilet that sits at 16-1/2 inches and is handicap accessible. This high efficiency toilet flushes at a rate of 1.6 gallons per flush, and uses a large trapway and flush valve for a powerful flush that can move a 70% larger mass than a standard toilet. The Everclean® surface from American Standard comes included with the Titan toilet, and helps to keep mold, mildew, and bacteria from growing in your toilet.
