Works great! And the flush is so quiet! I wish I could have found it with a 10-in rough in for my other bathroom.

water level in bowl
I recently bought two toilets and replaced my old ones. Toilet is good with size and height. only one problem I run into was toilet bowl water was too low. adjusted lot of stuff still the same. Found out interesting problem with small pipe. I am attaching the picture, if someone has the similar problem you can can benefit. you can see in picture the pipe came with Kohler tilted 90 degree and choked the water. I replaced the pipe with the another pipe from my old toilet. fixed the problem.

Happy with the toilets but wish there were instructions related to the flow regulator in the fill valve
I just installed 2 of these toilets and overall they have been great so far. When installing the first one I noticed that the tank filled very slowly (like 7 minutes) after flushing and the bowl barely had any water in it. If I turned up the main water valve to the toilet, the fill valve would stop filling and make a loud howling sound. After about 2.5 hours of troubleshooting I discovered on the Fluidmaster website that there is a rubber flow regulator in the bottom of the fill valve that you can simply remove with needle nose pliers. Maybe this is common knowledge to some but it wasn't to me. Had there been a simple note and/or diagram about this in the instructions it would've saved me a lot of time and frustration. Also, on this flow regulator in the picture there wasn't a plastic piece on the end like there was on the other toilet, maybe that's why it stopped filling when the water pressure was increased. I assume this plastic piece keeps the regulator from pushing into and blocking the fill valve pipe. Either way, I removed both and the toilets work great! One area that could use improvement are the 3 screws/rubber gaskets that attach the tank to the base, these seem like future leak points and took a little coddling to make sure they didn't leak during installation.

I'm very pleased with this toilet!! Its the perfect height, not too high, not too low. The height of my last toilet was too high!! I purchased online and picked up in store. It also comes with a slow close seat. It has a nice sleek look in my bathroom.

where is the quality control?
Purchased this toilet and do like it very much, however after unpacking I noticed a chip on the underside. That area was glazed like the rest, so that chip was created during manufacture. I did not see any other issues that would cause problems, so I did install the unit. Works just fine and looks good, but I question the quality control. Not American craftsmanship.

LOUD FLUSH WITH A GURGLE PLOP PLOP PLOP SOUND AT THE END
You can hear this thing GURGLE AND PLOP PLOP PLOP each time you flush it. I bought two of them and they both sound the same and are incredibly loud-sounding when you flush them. Also, I had to buy FIVE OF THESE before I got TWO of them that didn't leak and would sit flat on the floor and not rock. None of these things were installation issues. I finally got two that sit flat and don't leak. The quality control of this toilet needs some serious review by KOHLER. I even tried different production dates in my choices to see if that would make a difference. And say Made in Mexico. Not the quality that the KOHLER name used to be at all, nor Mexico. I wish I could add a video on here so you could hear how LOUD they are when then flush. Like the box says- they PLUGE THE WATER DOWN very well. What they don't say it comes with THE SOUND AS WELL OF A CLOGGED TOILET BEING PLUNGED EVERY TIME YOU FLUSH THEM. Not so nice.

Response from Kohler Product ExpertJuly 21, 2020
Hi LoudSounding, this is Sarah with Kohler Co. I'm very sorry to hear your Highline toilets are flushing with too much noise. When flushed, a toilet with a canister flush valve will be just perceivably louder than a toilet equipped with a flapper flush valve. However, the tradeoff is that toilets with a canister flush valve will have better performance including greater water efficiency. A canister flush valve is quieter than an assisted flush, featured in many commercial toilets. If both toilets are making a gurgling noise, we would suggest checking the rim feed tube and water level within the tank. The water level should be at the "water line" marked on either the back wall (inside) the tank or on the canister itself. The rim feed tube should be connected at both ends; connecting the fill valve to the flush valve. If either end is disconnected, it can be pushed back into place. Please email our Customer Service team at KohlerCustServ@kohler.com for additional assistance. It's important to us that your toilet is flushing and functioning as it should! -Sarah S.

Leaks
This is my 2nd. My 1st was leaking every time it was flushed, took it apart to find a crack under the base. My 2nd now is leaking but it’s sporadic. Now I will have to change this for the 3rd time since moving into my home 6 months ago. Not sure I will be replacing with another kohler, seems like more trouble than it’s worth

Toilet works great. I thought there wasn’t enough water in the bowl but this thing has been flushing like a champ. Uses less water and flushed great no clogs! Installation was easy. Everything is included. Only thing I had to buy was a new water supply line because the old one leaked.
