Our take on the Kohler Highline Two-Piece Elongated Toilet 1.6 GPF

The Kohler Highline is a two-piece elongated toilet built around Kohler's Class Five flushing system, which uses a large flush valve and a wide water surface to clear waste in one 1.6-gallon flush. The elongated bowl gives more seating room than a round front, and the chair-height option helps adults with knee or back trouble sit and stand more easily. It is a workhorse fixture rather than a feature-heavy one: no bidet seat, no smart controls, no hidden trapway. Against store-brand and builder-grade toilets it stands out on parts availability and brand support; against premium one-piece models it gives up a sleeker look and quieter flush.

Questions and answers

Is the Kohler Highline a good toilet?
Yes, for a basic, dependable toilet. It flushes well, uses 1.6 gallons, and parts are easy to find. It is not a quiet or feature-rich model.
How loud is the Highline flush?
It is louder than many premium one-piece toilets. Owners often mention the noise, so it suits a bathroom away from bedrooms.
Does it come in chair height?
Kohler offers the Highline in both standard and comfort-height versions. Check the model name, since the two sit at different heights.
What is included in the box?
The box has the bowl, tank, tank cover, fill and flush valves, and mounting hardware. A seat and supply line are usually sold separately.
Is it hard to install?
No. It is a standard two-piece install with a floor flange and closet bolts. Two people make setting the bowl easier.
How does it compare with a one-piece toilet?
A one-piece is sleeker and easier to wipe down, but heavier and costlier to replace. The Highline is simpler to install and service.
Where is the Kohler Highline Two-Piece Elongated Toilet 1.6 GPF cheapest?
At Lowe's, for $446.62, as of our latest check.
Where can I buy the Kohler Highline Two-Piece Elongated Toilet 1.6 GPF?
