Q:I had this toilet installed a few months ago. One complaint: It is so loud when it is flushed. I'm surprised it doesn't wake up the neighbors! Is there any way to make it flush more quietly please?

Terrible install instructions
The instructions on mounting the tank to the bowl are terrible. Had to watch a YouTube video to see that you need washers. It also says “don’t over tighten!” But there are these huge rubber gaskets that seemingly need to be compressed, but how much, we will never know because the instructions are so rudimentary. Also, there was a sizable chunk of porcelain sticking on the bottom of the bowl. This would have made the toilet sit crooked on the floor. Luckily I had an angle grinder to shave it off. I have installed the basic $100 toilets and they were way easier and still get your “stuff” flushed. Not sure why I paid so much to suffer through a terrible install!

Low Toilet Water Level Caused by "Kinked" Line
I had a problem reported by other people where the water level in the toilet was very low.
After a bit of searching I found the cause of the problem was the black rubber "water fill line" in the tank had a "kink" in it that was restricting the flow of water filling the tank. I was able to cut the line "shorter" to eliminate the kink and reconnect it and this solved the problem and the toilet now fills properly. This has been reported by other people, so is an issue to be aware of. See photo.

Not working as it should
The toilet looks pretty but the float valve is not working properly. The tank is not filling consistently on its own. I need to lift the lid and push down on the valve so it fills. My husband wanted to buy an American Standard toilet and I convinced him to buy this one, but now I am thinking I should have listened to him. Not happy with the product

Hi Lisa, this is Sarah with Kohler Co. I am sorry to hear your Highline Arc toilet is not consistently refilling. We recommend flushing out the fill valve which will likely resolve this. Here is a video showing how this can be done: https://www.kohler.com/en/support/help-and-faq/video-how-to-flush-the-fill-valve-on-kohler-two-piece-toilets.

New Throne.
Professional plumbers install the bolts that attached the bowl to the tank could be a little bit longer for user insulation other than that Good product.

Something is off
This toilet is really nice. Flushes great. Classic design. However, I'm not sure if I received the wrong tank but my take sits about three inches away from the wall. Not sure that I've ever seen a toilet tank not flush to the wall.

Lousy execution
Kohler, are you listening? I hope so...
I bought this toilet today at Home Depot, not my first toilet installation. It was nice that all the hardware is included but what would have been better is if it was actually usable! The bolts to attach the tank to the bowl were too short to clear the bowl and get the nut and washer on it. About a half inch longer would have been great. After two hours trying to make yours work I ended up using my own bolts. Stupid error on Kohler's part.

Ba-Woosh!
Powerful flush, very comfortable. We love the Kohler plug-in Bidet attachment as an upgrade. This combination defines the word Throne. Love it!
