I bought two of these toilets on 12/5/13 for $238 and installed one and tried to return the other.  The retailer would not accept the toilet because the box was open.  Kohler's description is:  http://www.us.kohler.com/us/Highline-Comfort-Height-two-piece-elongated-dual-flush-toilet-with-Class-Five-flush-technology-and-left-hand-trip-lever/productDetail/Styles-of-Toilets/428216.htm?brandId=429997&skuId=409691&categoryId=429984&hash=id%3Dfilters%26startIndex%3D20%26scrollTop%3D0.  This is an elongate bowl that is 16.5 inches tall w/o the seat
