So a few things. Many reviewers have complained about the toilet-tank seal. They are doing it wrong.
You must tighten them a lot. I mean A LOT. I had one professionally installed so I had a baseline to work from.
The three plastic bolts in the tank MUST BE FLUSH with the bottom of the tank. That's when you know that you've tightened enough. You will have about 1/8" between the tank and toilet - yes, you squish the seal immensely - that's the point! You will think that you're going to break something but trust me, you will be fine.
I also have no idea why people are having problems making it level. That part is extremely straightforward.

Rated 3 out of 5Â by kevind nice toilet, but.
As mentioned by others here, the seal between the tank and the toilet seems to be the main problem.
I had no problems installing the bowl to the floor, but installing the tank to the bowl and getting it level and sealed is a huge pain in the butt.
I have not installed many toilets over my lifetime, but all were 2 bolt tank to bowl systems that worked perfectly and installed easily.
Kohlers 3 bolt system just turns what should be a simple job into rocket science.
However, once i did get the thing working as it should, it flushes really well, and although not a dual flush in the sense that it has 2 separate buttons, it does do a small flush with just a quick press and release of the handle, or a bigger flush if you hold the handle for an extra second or 2.
Quick summary, i like the finished working product, but the install is more difficult than it should be.

Rated 1 out of 5Â by BadFireHazard Not too impressed with this "very nice" toilet.
The seal between the bowl and the tank is a massive design flaw.
Sure it was easy to install, but to get the tank level and sealed properly was the tricky part.
I check on the "seal" every few days. To make sure it is not dripping.
No more Kohler for this guy.

As another reviewer mentioned, the toilet tank's "patent pending" seal require's babying and definitely undertightening as opposed to tightening with a wrench as their instructions depict. The rubber seal is a one-piece that seals the tank-to-bowl connection and the three (as opposed to 2 on most other brands) tank anchoring bolts. As soon as you start to seat the rubber seal by tightening one of the anchor bolts the seal distorts. After installing multiple American Standard toilets I simple tightened the Kohler tank snugly, turned on the water and it was like the second flood! Water running out of the bottom of the tank so profusely that I thought the tank surely must have a hole.
I had to take the tank off, wipe it dry and start over, very gingerly hand tightening the bolts. The seal is still distorted a bit and I'm nervous that one night it will spring a leak and damage our house.
Part of the issue is the tank hole ring part seems to be too big to really fit snugly into the bowl hole. Bad design! Hope they don't get that Patent because I sure don't want to have to deal with that on ALL their toilets!!!
This is also a fairly low toilet. Definitely not "comfort height". Good if you have younger children - which we do.

Rated 1 out of 5Â by gt63 "Do not over Tighten"
The tank mounts with three bolts instead of the normal two. There are no torque ratings for these bolts, the instructions only state "do not over tighten". I mounted the the tank with equal counted turns on each bolts, alternating each bolt after 2-3 turns each till they seemed snug but not "over tightened". Everything looked good, solid mount, no rocking, time to turn on water. Before I could turn on the water supply there was a loud snap sound from the tank. Turns out I apparently "over tightened" the tank bolts and broke the rear bolt flange off the bowl section which turned my new toilet into $217.00 worth of junk. If you purchase this toilet, please try to find torque setting for the tank bolts before installing. I have repaired and installed auto and home products for 40 years and know how to not "over tighten" a bolt, please beware!
