The Kohler Highline Arc is a two-piece, round-front toilet built for small bathrooms and powder rooms. It uses Kohler's Class Five canister flush at 1.28 gallons per flush and ships as a complete kit with bowl, tank, seat, wax ring, hardware and trip lever. The round bowl saves space where an elongated bowl won't fit, but it offers less seating room than elongated models. Owners rate it well for flushing power and easy installation; a few mention a loud flush and seats that feel basic.

Owners rate the Highline Arc highly, mostly for strong, clog-free flushing and a straightforward install with all parts included. Criticism centers on flush noise and the plain included seat.
