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

The Kohler Highline Arc is a two-piece elongated toilet with a 1.28-gallon single flush and a 12-inch rough-in. It comes as a complete solution: bowl, tank, seat and wax ring are in the box, so there is no separate trim kit to buy. The elongated bowl and slow-close seat suit busy family bathrooms. Against cheaper builder-grade toilets it brings Kohler's proven gravity flush and a sturdier build; against premium comfort-height models it sits at standard height and offers no dual-flush option.

Questions and answers

Is this a complete toilet or just the bowl?
It is a complete solution: bowl, tank, seat, lid and wax ring are included. You do not need a separate seat or trim kit.
Will it fit my existing floor drain?
It fits a standard 12-inch rough-in, meaning the drain center sits 12 inches from the finished back wall. Measure before ordering; 10- and 14-inch rough-ins need a different model.
How much water does it use per flush?
1.28 gallons per flush on a single gravity flush. That meets WaterSense criteria and is lower than older 1.6-gallon toilets.
Is the seat slow-close?
Yes. The included seat and lid close slowly to prevent slamming.
Does it come in other colors?
Kohler offers the Highline Arc in several finishes, including white and biscuit. The brown finish shown here is less common and harder to match with other fixtures.
How does it compare with the Kohler Wellworth?
Both are two-piece 1.28 GPF elongated toilets with a 12-inch rough-in. The Highline Arc has a more transitional tank shape and ships as a complete kit; the Wellworth is often sold as bowl and tank only.
Where is the Kohler Highline Arc The Complete Solution 2-Piece 1.28 GPF Single Flush Elongated cheapest?
At The Home Depot, for $189.00, as of our latest check.
