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.

Owners of the Highline line generally praise the strong, quiet flush and the easy installation. Taller users single out the extra height as the reason they bought it. Complaints center on the seat height being too high for shorter household members and on the supply line being extra.
