Our take on the Kohler KOH3493-RA-0 Highline 1.6 GPF Two-Piece Elongated Comfort Height Toilet with Right Hand Trip Lever – Less Seat

The Kohler Highline is a two-piece elongated toilet with a Comfort Height bowl, which puts the seat at roughly chair height for easier sitting and standing. It uses a 1.28-gallon flush and comes as a right-hand trip lever model without a seat. Compared with basic builder-grade toilets, it offers a taller bowl and Kohler's Class Five flushing, but you pay more and must buy a seat separately. Owners generally like the height and reliable flush; some note the plastic flush components and the extra seat purchase.

Questions and answers

Does it come with a seat?
No. This model is sold less seat, so you need to buy a separate elongated seat. A standard elongated seat fits the bowl.
What is Comfort Height?
It means the bowl rim sits at about chair height, roughly 16.5 inches, instead of the standard 15 inches. That makes sitting down and standing up easier.
Is it a good replacement for an older toilet?
Yes, it fits a standard 12-inch rough-in, so it usually drops in where an old toilet sat. Check your rough-in measurement before ordering.
How much water does it use?
It flushes with 1.28 gallons, which meets WaterSense standards. That is less than older 1.6-gallon models.
Which way does the handle face?
This is the right-hand trip lever version, so the handle is on the right side as you face the toilet. A left-hand version exists for other layouts.
Is it hard to install?
It is a standard two-piece install with a wax ring and closet bolts. Many owners do it themselves, though a plumber is safer if the flange is damaged.
