We at Toiletable are big fans of Kohler. The company is known for well-built models that prioritize user experience. The Adair is no different.

Flushing Performance

One of the most impressive parts of the Adair is its AquaPiston canister which increases water flow and streams across every side of the bowl. The high-quality canister withstands the test of time through its durable non-deteriorating material. The canister also has a low actuation force making flushing as simple as can be.

The Adair also has a 3:2 flush valve ratio that optimizes flush performance and a reliable canister design has 90% less exposed seal material than traditional three-inch flappers, reducing chance of leakage.

This unit utilizes 1.28 gallons per flush, saving you thousands of gallons a year, when compared to traditional 1.6 gallons per flush units.

Smart Design

This one-piece ADA-compliant unit has a Comfort Height of 16.5” and a comfortable elongated bowl. Comfort Height toilets simulate a standard chair-like setting, allowing users to easily sit and stand up.

We’ve reviewed hundreds of toilets and one of the most frustrating parts is when an excellent toilet does not come with a matching toilet seat. Well, with the Adair this problem ceases to exist thanks to the inclusion of the Cachet Quiet-Close elongated seat. The Quiet-Close seat resists wear-and-tear by preventing annoying seat clanging.

The toilet is available in white, biscuit, almond, dune, ice grey, sandbar, mexican sand, cashmere, thunder grey, and black black. In addition to a seat, the toilet comes with a tank, bowl, bolt cap accessory pack, tank accessory pack, and tank cover. A left-hand chrome polished trip lever is included as well.

This toilet uses a standard 2 ⅛” trapway. The concealed trapway simplifies cleaning by eliminating potential spots that may harbor bacteria and grime. The toilet’s curved tank is sleek, soft, and glossy. The tank lid is stable enough to put things on.

If you are looking for a more luxurious seat, the Adair is compatible with the Nightlight Quiet-Close elongated seat, which lights up the bowl so you don’t have to turn on the lights on your nighttime bathroom trips.

If you’re looking for a bidet-like situation, try the elongated cleansing toilet. It’s a removable bidet seat that provides a spa-like experience for the fraction of a smart toilet.

Summary of Customer Reviews

Not many reviews are available for the Adair. The positive ones tend to focus on the Adair’s effective flushing mechanism and durability. Some users note that they wished the toilet was higher. Another complaint is that the toilet is a bit pricey for a non-smart toilet. However, the Adair does come with a Quiet-Close seat which is a plus.
