Thank you for your Inquiry. The Devonshire Comfort height, 2 piece, Elongated Toilet does not come with a Seat. The seat needs to be ordered separately. we apologize for the confusion.

Customer Reviews

Rated 4.2 out of 5 by 49 reviewers.
Rated 3.0 out of 5.0 by Good toilet but... Liked this toilet just fine until the first time it clogged. Due to the design of the bowl a plunger will not seal and is completely ineffectual. There is a small trough that causes the problem. Something to watch out for on other models too. August 23, 2016
Rated 1.0 out of 5.0 by Tank Has Leaked Consistently since it was installed I installed and it went in very easy. I worked great for about two weeks. At the two week time period, the water wouldn't shut off after flushing. I read through the reviews and found someone else with the same problem and found Koehler provided a link for fixing it. I did as the link instructed and it worked for about 3 more weeks. It then started again so the water wouldn't shut off after flushing. I repeated the fix and it again worked but only for a short time. I've know tried to fix this at least a half dozen times and the water now never shuts off.. It has been very frustrating dealing with this. I'm not sure what to do next. June 23, 2016
Rated 3.0 out of 5.0 by I think this will work in the long run Once I had the correct ring and toilet bolts (not the ones matched to my online purchase by Home Depot), the installation was easy and uneventful. About three weeks after the purchase, the toilet wouldn't shut off on its own. We keft having to remove the tank cover and tap on one of the internal parts to make the water shut off. I read other reviews of this product and found a second person with the same problem. Kohler provided this person a link for a do it yourself fix. I followed the directions provided and the fix worked. I would have ranked this a 5 star if I hadn't had to do a repair already. If this is the only fix I have to do, the product itself has been great. I bought it because of the aqua piston because the last toilet we had in our upstairs would only flush liquids and would have to be plunged for anything more. This toilet flushed all that needs to be flushed. I hope it continues to work as well as it is working now! May 31, 2016
Rated 5.0 out of 5.0 by New Toilet This was exactly what we needed to complete our bathroom. Looks great! April 19, 2016
Rated 5.0 out of 5.0 by Efficient and good looking I bought this toilet for my last home; so, when I moved into this home and found Its toilets needed 2-3 flushes for solid waste, I knew where to go. I really like the look of this toilet and have never flushed it twice. I was surprised by the new flush mechanism, though. It is so fast and quiet, I found myself checking to see if it worked. Clean bowl every time! I can't speak to installation. I had a plumber do that. April 6, 2016
Rated 1.0 out of 5.0 by should of read the whats included Ordered this toilet and it was shipped 3 times to the store broken...had no problem with that, due to the fact that I wasnt ready for it yet. After It came in unbroken, I brought home and discovered that there was no seat included. Very unhappy about this.....If I bought this toilet from there competitor, it would of included everything including the wax ring, for the same price as home depot. This is what happens when you try to find the best price...the department stores subtract items that should of been included, so the price looks better. March 6, 2016
Rated 4.0 out of 5.0 by Very nice toilet. The toilet looks as good installed as it did online. Works great, no issues, even for a water saver model. My only complaint is that because the water tank appears smaller than my old toliet, their is a larger gap between the tank and wall than with my old toilet (and I measured the rough in to ensure I ordered the right toilet).

Rated 5.0 out of 5.0 by Beautiful addition to glamorouse new bathroom The wify poo loved it as soon as she saw the picture on line. March 1, 2016
