Our take on the Kohler Highline Arc The Complete Solution 2-Piece 1.28 GPF Single Flush Round

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.

Questions and answers

Does it come with everything needed to install?
Yes. The Complete Solution package includes the bowl, tank, seat, wax ring, mounting hardware and trip lever. You supply the water supply line.
Will it fit my existing rough-in?
It is designed for a standard 12-inch rough-in, the most common in US homes. Measure from the finished wall to the closet bolt centers before buying.
Is the round bowl a problem for adults?
It saves space in small rooms, but the round opening is shorter front to back than an elongated bowl. Taller users often prefer elongated.
How much water does it use?
It flushes 1.28 gallons per flush and meets WaterSense criteria, so it uses less than older 1.6 gpf toilets.
Is it loud?
The gravity flush is effective but not among the quietest. If the toilet sits next to a bedroom, expect to hear it.
Can I replace the seat later?
Yes. It takes standard round-front seats, so a slow-close seat is an easy upgrade.
