Product Technologies / Benefits:

  • AquaPiston: AquaPiston single flush canister technology uses the force of gravity and a precision-engineered tank, bowl, and trapway to create a strong, efficient siphon during flushing. The canister flush valve's 3:2 ratio optimizes flush performance and resists warping and deterioration, while its durable design features 90% less exposed seal material than a standard 3-inch flapper flush valve, guaranteeing leak-free performance. The light-touch canister requires lower activation force than a flapper, and once activated, allows water to flow into the bowl from all sides (360 degrees), increasing each flush's power and effectiveness.
  • Comfort Height: Comfort Height toilets offer the greatest accessibility and ease of use with a bowl height of between 16-1/2" and 18", the same as a standard chair.

  • Overall Height: 30-3/4" (measured from bottom of base to top of tank)

Kohler K-3589 Reviews

Rated 5 out of 5 by from A wise choice This is a great toilet. Handles waste very efficiently and has clean lines. The price is great, too. I plan to redo my other bath and will use this along with the Expanse tub, which also has a nice curve to it. My only complaint is that "comfort height" is not really comfort for me - I am 5'2" and my feet don't touch the ground !

Rated 5 out of 5 by from Excellent toilet This toilet has been installed for over two years and operates flawlessly! I have no issues with it at all. Would highly recommend this product.

Rated 1 out of 5 by from The worst toilet I ever purchased After a little over a year, the handle would not flush, due to the chain inside the tank falling off. The plumber said this was the worst toilet, and most of his repairs are this toilet. He put the chain back at least 6 times, and had to use a paper clip to keep the chain from falling off when the toilet is flushed. Finally, it broke, and the toilet has to be replaced, never mind the expense of the plumbers and replacement costs. Also, the toilet seat never stayed in place, due to the cheap plastic nuts or screws. It kept sliding around and around, and needed manual tightening after every use. I have owned many toilets. This was the worst.

Rated 1 out of 5 by from Cimarron toilet Just had this installed 3 days ago and do NOT like it. I'm 5'1" tall and my feet don't touch. Plus the toilet seat is higher on the outer rim and is very uncomfortable. I've never seen a toilet seat like it. My legs would go to sleep if I sat on it for long. VERY UNCOMFORTABLE....can't afford to replace it so I'm stuck.

Rated 5 out of 5 by from Good Product I bought 5 of these for my new construction home. I've not had any problems, plumber didn't complain about anything regarding installation and they handle waste very well. One of the few 1.6 gal toilets left out there. Only issues were that one tank arrived broken (didn't accept delivery and was replaced) and one toilet was missing the hardware. Neither was a problem as with new construction, the plumber had many other jobs to keep him working while waiting for replacement parts. My wife is 5'4" had has no complaints. My kids do have to "climb" on, but not worth buying round, regular height now only to replace later when they grow. Just open every box before accepting delivery. Bought the quiet close seats that work great...no more slamming lids with the kids.
