Nice looking toilet. Took 3 attempts to install, the fancy bolt set up moved twice before I got both lined up properly. Worked nicely at first until moisture trapped under the tank lid starts to cause unnecessary flushing. Kohler took a few weeks to send a fix kit which is basically a foam pad. It worked for a few days and now we are back to ghost flushing running up my water bill. The underside of the tank lid is dripping wet and I am wondering how long before I have mold growing under there. I am a Kohler fan when it comes to sinks and engines but for $700 I am disappointed in this toilet and we are thinking of taking it back to HD.

Bought 2 of these. One lasted 6 months the other 2 years. I loved the toilet while we had it but auto flushing every 20 seconds is (I'm looking for a word)... just tore them both out, no longer using kohler.

Rated 1.0 out of 5.0 by IB909canscuba Way over priced for the defects. DON'T BUY ONE!!
We remodeled our master bath and bought this toilet in Dune color and paid $800.00. Going by the brand name "Kohler" and paying a high dollar amount, we expected perfection. To the contrary, after 1 month it started flushing on it's own consistently, we finally had to shut water valve off. Called Kohler and they sent a new mechanism to install and that fixed the problem, so far. Now the toilet flapper chain kinks up and causes the toilet to run. Once we fix the chain it works about 3 days before it kinks up again. Our prior $200.00 dollar toilet never gave us a problem in 8 years, should have kept it. We are very upset that we purchased this overpriced defective toilet. Would NOT recommend this toilet to anyone.

Rated 5.0 out of 5.0 by happynow123 Love our Modern Kohler Toilet
LOVE THIS TOILET, most especially the low modern design of it. It looks awesome in our modern bathroom. We liked the first one we bought so much we bought a second for our guest bathroom also. My husband who is a handyman didn't have any problems installing either of them and they both work great. Only drawback is the hand activation mechanism flushes the toilet when wiping the top of the toilet clean. So that wastes water. Maybe there is a way around it that I don't know of. If not, then I probably would prefer the handle over the hand activated. Love the quality, modern design and the price is higher than average but worth it. Thank you for a great product Kohler!

Forget Kohler's repair advice. The foam pad they send out to solve the ghost flushing issue doesn't work for long and immediately started to grow mold. Instead cut the foam pad into strips about 1/4 inch wide,you will need 6. Take the tank lid off. There is a raised lip the lid sits on. Apply strips of foam to the left and right side and in the middle of the front. Apply strips on top of each other, 3 spots doubled up. This raises the tank lid and balances it. It still fits properly and secure and lifts the lid enough to allow it to breathe and you can get a finger in under the back. Lifting the lid causes the flush sensor to not work. I had a piece of plastic rod you may be able to use foam strips. Place under the sensor bracket lifting sensor up to match lid lift. This slightly tilts the sensor forward so I gently bent the bracket toward the back making the sensor sit level and my problem has been solved. The toilet works, no ghost flushing so far. I still have some moisture under tank lid but much less than before and it is not dripping onto my sensor. You are welcome Kohler my invoice is in the mail

Rated 1.0 out of 5.0 by Biskert Garbage - Electronic Portion Fails Within 60 Days
Hi, I purchased the K-4000 two months ago and now it will not flush except for taking the lid off and flushing it manually. Before the batteries ran-out of power, the toilet flushed on its own - without human intervention. I changed the batteries twice and now the toilet will not flush at all. There is nothing on the tank lid such as tissue boxes, wet wipes or decorations that can cause the sensor to activate. The chain attached is devoid of any slack. There are no metallic or damp items within 10" of the sensor. Steam is not present when the unit activates and venting in the room excellent. The touchless module or tank lid is NOT wet and there is NO condensation causing the sensor to activate.
I'm saddened, troubled and disappointed that an expensive toilet could fail so quickly and hope Kohley will rectify the situation immediately. Thank you.

I had a professional plumber install the toilet, however, he indicated that it was easy to install and that it looks great in our new bathroom remodel.

The toilet works fine and there are no phantom flushes.It works well in a small bathroom. Installation was easy enough once I exchanged the plastic guides for the more traditional metal bolts which did not bend while attempting to set the 80 lb toilet on the wax ring. Also for the price I would have expected an $ 8.00 wax ring to be included.
