Our take on the KOHLER Highline Arc Extra Tall 2-Piece Elongated Toilet, White, 1.28 GPF - 78305-0

The Kohler Highline Arc is a two-piece elongated toilet with a 19-inch bowl height, roughly comfort height plus a couple of inches, aimed at taller users and people who have trouble bending low. It flushes at 1.28 gallons and comes as a complete package with the tank, bowl, Quiet-Close seat, wax ring and hardware. The fully glazed 2-1/8-inch trapway and three-bolt quick-connect setup are the practical highlights. Against standard-height Highline models it trades a taller, easier-to-reach bowl for a slightly larger footprint and a higher seat that shorter users may find awkward.
