Our take on the Kohler Highline Comfort Height Two-piece elongated dual-flush chair height with 10" rough-in

The Kohler Highline Comfort Height is a two-piece elongated toilet with a dual-flush system and a 10-inch rough-in. Its chair-height bowl (about 16.5 inches to the rim) makes sitting down and standing up easier than a standard-height toilet, which suits older adults and anyone with knee or hip issues. The dual flush lets you choose a lighter flush for liquid waste and a fuller one for solids, so it uses less water than a single-flush toilet on average. Against rivals, it is a straightforward, widely available model with a simple two-button actuator on the tank; it lacks the concealed trapway and skirted base of Kohler's sleeker one-piece designs, and some owners find the flush louder than premium models.

Questions and answers

Is the chair height worth it?
If anyone in the house has knee, hip or balance issues, yes. The taller rim means less bending, and most owners notice the difference right away.
How does dual flush work here?
Two buttons on the tank give a smaller flush for liquid waste and a fuller flush for solids. The smaller flush uses about 1.1 gallons and the larger about 1.6.
Will it fit my bathroom's rough-in?
This version is made for a 10-inch rough-in, measured from the finished wall to the drain center. Measure before buying; a 12-inch rough-in needs a different model.
Is the elongated bowl better than round?
Most adults find elongated more comfortable, but it takes up more floor space front to back. Check the room in front of the toilet.
What is included?
You get the bowl, tank, lid and flush buttons. A seat and supply line are usually sold separately, so confirm before ordering.
How does it compare with a one-piece Kohler?
One-piece models look sleeker and are easier to wipe clean, but they cost more and are heavier to install. This two-piece is simpler to service.
