Rated 4.5 out of 5 by 157 reviewers.
Rated 5.0 out of 5.0 by Best Toilet Ever - and the Best Deal I now have 2 of these, replace over the last 4 months. My old toilets would plug practically every day. These new toilets have not plugged a single time, and flush with amazing power while only using 1.28 gallons per flush. You can hold the handle down for 2-3 seconds to get the maximum flush, but it is seldom, if ever necessary. I installed them both myself (just be careful not to over-tighten the bolts), using separately-purchased REINFORCED wax rings. Be sure to level/stabilize the toilet with shims and re-tighten the bolts after a few days or weeks (see the how-to video on this site). Seal to the floor with silicone sealer. Note that the biscuit color is lighter than almond. April 15, 2014
Rated 5.0 out of 5.0 by Just what I wanted I wanted to replace my contractor grade toilet which easily clogged with a quality toilet which flushes well. I ended up choosing the Kohler Cimarron Comfort Height 1.28 gpf. It is a 2 piece toilet. Bolting the tank to the toilet is much nicer now do to a bracket under the tank that holds the bolts. No more having to worry about them going down through the tank. When you flush it, it does not seem like it has a lot of power but in 3 months time, it has not once clogged or required a second flush. It does sit away from the wall pretty far but that is based on your rough-in. My only complaint is it does not come with a seat (but I new that before I purchased it). May 21, 2014
Rated 5.0 out of 5.0 by Very Happy with this Purchase! Works great, uses very little water, and has a powerful flush. All of which are very important in a house full of teenagers. September 16, 2014
Rated 5.0 out of 5.0 by I've had two other Kohler toilets installed and they are great. I had a plumber install the toilets. It did not seem to pose ant problems. I'm amazed at how little water they seem to use for flushing. Great toilets. November 3, 2015
Rated 5.0 out of 5.0 by Love it! Needed the high seat but small bathroom required the round bowl. Worked out very well, easy to install ( we're in our 70's and did it ourselves) Flushes very well with so much less water and the compact size is perfect for the room. December 10, 2013
Rated 5.0 out of 5.0 by We love it! Best functioning toilet we've ever had, married 40 yrs. Great price too especially since it's bisque color, at the store a similar one had to be ordered and would cost at least $100 more. Also because it's a little taller it allowed our son, a stroke survivor to use a regular toilet instead of one of those icky raised jobs. April 3, 2014
Rated 5.0 out of 5.0 by Flushes better than any toilet I have tried. our remodeler installed so I can't comment on that. Great flushing performance and quick refill. Needed special order due to biscuit color not in stock. Delivered to our home but the tank arrived cracked. Be sure to check special delivered products upon arrival so, if need be, another one can be ordered promptly. Home Depot customer service and sales personnel in Machesney Park, IL were extremely helpful and accommodating. January 15, 2014
Rated 5.0 out of 5.0 by Better Than Best Toilet I did all my research, then replaced a 1985 toilet (3.5 gal flusher) with the 1.28 gallon flusher Kohler Cimarron toilet (Biscuit color). It went into a medium size bathroom. I'm amazed at how well this toiled flushes "all" with one tap of the lever, and does it pronto with little noise. Just a tip for some folks: you may have a floor that isn't perfectly flat, which I did (off about 1/8th inch). In my case two plastic toilet shims were "fitted" under the toilet on a test placement of just the bottom part of the toiled. I leveled the toilet with two shims in back, marked the exposed part of the shim with masking tape, and surrounded the entire shim with plastic tape for proper placement of the shim. I removed the toilet, cut the plastic shim with a strong kitchen knife, and then glued the shim to the time with a 2-part epoxy that dried in 30 minutes (to keep the shim locked in place). When I placed the toilet it was perfectly leveled. This is the only 2-piece toilet where the water tank bolts do NOT invade the water tank. No worry about future water tank bolt deterioration. Oh yes, I also installed the Kohler lighted seat. Way cool that is and a nice conversation piece among friends. I bought the round bowl to avoid to much of the toilet invading bathroom space in the front. Round works great. I love my toilet and I love bragging about my lighted seat. I know, it's wierd! .
