Product Overview

Featuring the classic, versatile look of the Cimarron collection, this 2-piece toilet combines water-saving flush performance with graceful curves. A 1.28 GPF design provides up to 16,500 gallons of water savings per year, compared to a 3.5-gallon toilet, without sacrificing performance. This toilet features innovative AquaPiston technology, a patented flush engine, that delivers a fast, powerful and plug-free flush. The round-front bowl is positioned at a convenient height for comfort and ease of use. For added convenience, this model comes with all the necessary installation parts.

  • Single-flush gravity uses the force of gravity and a precision-engineered tank, bowl and trapway to create a strong siphon during flushing
  • AquaPiston canister allows water to flow into the bowl from all sides (360 degrees), increasing the power and effectiveness of the flush
  • Flush valve's 3:2 ratio harnesses the natural force of gravity and optimizes flush performance
  • Durable canister design has 90% less exposed seal material than a 3 in. flapper for leak-free performance
  • Light-touch canister flush requires a lower actuation force than a flapper
  • DryLock system saves installation time and helps prevent water leakage
  • WaterSense toilets meet strict EPA flushing guidelines, including using at least 20% less water than 1.6-gallon toilets
  • Available exclusively at The Home Depot

Answer: 
if you do caulk, leave a one inch gap towards the back of the toilet in case it does leak. That way you'll know if there's a leak.

I know this is an old question but it always seems to get asked and gets a lot of disagreement. So my two cents. I have installed hundreds of toilets and the majority of them have been caulked because the majority of them have to be shimmed in some manner due to variations in the concrete floor or the toilet bowl base itself. If it is a wood floor and somewhat wobbly itself, shimming and caulking may not help at all. I use soft shims that are designed for that purpose and cut easily with a box knife when in place, I have also used regular builders wood shims in a pinch. The caulking not only hides the shims but also helps hold them in place. I leave about a 2" gap on the back side of the toilet uncaulked so the water can seep out if the (wax or other) seal ever fails. Having said the above, that doesn't mean caulking is always necessary for stability, but some plumbing codes require caulking or a watertight seal. As a plumber, I hate it when I run across a toilet that I have to pull that has been grouted in place, latex based caulking removes easily with a razor blade paint scraper. The more you are trying to hide the more caulking required and the more difficult to make it look like it isn't even there. I also use clear caulking if I am not trying to hide the shims. Read Less

Answer: 
Even though it is not required, I always lay a bead of clear latex around the base just to keep unwanted water and urine from seeping under it. Use a wet rag and remove all but a fine bead with your finger and you don't notice it. It takes all of 5 minutes and may eliminate unwanted odors.

Answer: 
If you mount the base correctly to the wax ring then there is no need for any caulk. Caulk would only help keep gases from escaping from underneath the base but if you are getting gases then you mounted it to the wax ring wrong or you are using the wrong size wax ring. Of course, if it makes you happy feel free to caulk away.

Dual flush toilets normally have a flush button on top of the tank.
Press one side and you get a full flush for solids. Push the other
side and you flush with only 1 gallon of water for liquid waste.

What that does is eliminate most potential clogging in that it's not one of those toilets that the water slowly swirls around in then slowly goes down- it's more like a huge plug at the bottom is pulled and everything goes down immediately. SO much better than our old toilet! I really think this is the best one out there for the money and the extra height for a guy that's close to 6'2" is very noticeable and adds to comfort. Read Less

Rated 4.4 out of 5 by 321 reviewers.
Rated 5.0 out of 5.0 by Easy to install, saves water, very quiet, looks great It came with all the parts, but I did buy a better wax ring with a rubber collar. The tank does not have holes for the bolts that hold it to the bowl. It has a metal bracket on the bottom that holds the bolts, so the chance of leaks is greatly reduced. THe tank to bowl gasket is wide and matches the gasket fastened to the tank. THe seat was easy to bolt to the bowl too, and comes off easily for cleaning. THe flush handle takes just a quick push for yellow water. Hold the handle a half second for a greater amount of flush water. Fills fast and quietly. Looks beautiful! THe extra height is nice as I am tall. The flush parts in the tank are all assembled and ready to use. You can adjust the water level by simply turning a knob. July 18, 2016
Rated 2.0 out of 5.0 by Thought this was a good toilet but...... I had this toilet for over a year now after getting my bathroom remodeled and have ran into 2 problems. One, it got clogged and overflowed with barely any tissue in it causing floor and ceiling damage below (toilet on 2nd level). Also, within the last couple of months, if you use this toilet, you have to raise the top up and manually stop the toilet from running by lifting up the ball handle. I don't think I should have to get a plumber out just to fix a toilet that is barely over a year old nor should I have to be subjected to lifting the lid up every potty trip either....I am truly annoyed. August 8, 2016
Rated 5.0 out of 5.0 by Great Product We liked the first one we bought so much that we bought a second one to use in a very small powder room. That had a Cadet from 1989 and the distance from the wall was an issue. This toilet fit perfectly, it was only a bit longer from the wall but still did not go passed the door jamb. And for some reason unlike the first one the tank fits against the wall, nice surprise. We selected the round bowl like the first one. We are very happy with the comfort height, it really makes a difference. Now when we see an old style toilet we can't believe how low it looks! August 13, 2016
Rated 4.0 out of 5.0 by Great Flush for Low Flow Toilet The installation was very easy and I was able to complete it without any help as the toilet base is not excessively heavy. The attachment of the back was also very easy since the screws do not go through the bottom of the back and instead are inserted into an attachment plate on the outside (bottom) of the bowl. My one complaint is that the toilet sit lid that comes with the unit is very thin and flimsy plastic. Additionally, I thought that I had read it was a no slam lid, but that is not true, and I have not had time to find where I thought I had read that. I will likely be putting a different toilet sit on this unit that is of better quality, which I was hoping to not have to do with the high cost of this unit already. August 9, 2016
Rated 1.0 out of 5.0 by Very disappointed in the product and even more disappointed with Koher customer service I purchased this toilet to replace an existing toilet. Not long after I installed the toilet it started flushing erratically. I tried changing the batteries figuring they might be low on charge. This seemed to work for about a week, but then the erratic flushing began again. So I changed the batteries again, this time it only took three days for the problem to reappear. I would have to remove the batteries altogether to get the toilet to quit flushing. I decided to call Kohler's customer service to see if I could get an answer why the toilet flushed erratically. Upon reaching Kohler customer service I was told they were to busy to take my call and a recorded message gave me a webpage, that did not work, to contact. I can not believe that Kohler does not have better service. I will not be buying or recommending their products in the future. July 25, 2016
Rated 5.0 out of 5.0 by No complaints here! My brother replaced my 35 yr. old harvest gold toilet with this shiny new white one and it was a happy day for me! The comfort height and seat were so much more comfortable than the old one and there is no shifting of the seat at all. The smaller tank system is amazingly more efficient than before and it flushes with good power and saves so much soft water. It was easy to install but we did mess up the first wax seal and replaced it with a better one that had the funnel thingy that fit in the hole. I just love it and next to go will be the harvest gold tub. July 9, 2016
Rated 5.0 out of 5.0 by Great Toilet I can't believe how little water this thing uses. And how fast and quietly it flushes. The included seat is cheap but I put on my Toto Washlet seat. With that seat on, it sits a little high for my 5'3" wife but is still usable. I highly recommend this economical toilet. August 2, 2016
Rated 5.0 out of 5.0 by simple installation. low volume flush, would recommend. had a cracked tank on existing 25 year old toilet. Decided on replacing the entire unit. Was a surprise job, so, I didn't really do any homework on best toilet to replace it with. Actually purchased the toilet based on price and availability. Simple installation. All parts were in the box. higher seat than most, which is a plus. prefer the "oval" to the oblong as they seem to use the space better. would highly recommend. July 19, 2016
