The sophistication of traditional design serves as the inspiration for the Memoirs collection. With its rich detailing, this suite of products echoes the stylized lines of historically renowned furniture and architectural design Two styles offer different dignified interpretations - the clean, crisp lines of the Stately design, and the added rounded detail of the Classic style, which resembles crown molding. With fixtures and faucets available, the extensive Memoirs collection can accommodate both large and small bath and powder rooms.

Rated 4.9 out of 5 by 10 reviewers.
Rated 5.0 out of 5.0 by Awesome toilet. Ordered this toilet on line and had it shipped to the store instead of having it shipped to my home. The reason for this, is that I wanted to make sure that the product was not damaged in transit. Let me tell you that the packaging was superb. i mean this toilet was really well packed. I was impressed. Needless to say, the item was not damaged. It's a Kohler, so of course the quality is excellent. Easy to install just like any other toilet. The comfort height is perfect. Don't bother with the 1.2 Gallon per Flush, it's just too low to properly flush a toilet. I would highly recommend this toilet to anyone. It also looks beautiful. March 17, 2014
Rated 5.0 out of 5.0 by Great toilet Returned the 1.28GPF because I was disappointed with flushing. Very impressed with the 1.6GPF. It's effective and attractive. Highly recommend. Easy install as well. April 8, 2015
Rated 5.0 out of 5.0 by Great flushing mechanism This is our third identical toilet. The memoirs toilet flushes beautifully, reducing cleaning time, and looks great, too. The installation was very easy. The top connects to the bottom with three hand tightened bolts, and we were done in very little time. Our only delay was having to go get a wax ring (you only need the standard one) and a toilet seat lid. August 19, 2014
Rated 5.0 out of 5.0 by What a great update to our bathrooms The chair height elongated toilets are fantastic for those of use with older people in your home. The style gives any bathroom a very upscale classy feel, a bit expensive when you buying 3 like I did. But you get what you pay for with kohler. Flushing power is awesome and the water savings is awesome!! October 8, 2014
Rated 5.0 out of 5.0 by great toilet flushes everything! This is the answer to all our backed up toilets. No more embarrassing our guest when the toilet backs up! July 7, 2013
Rated 5.0 out of 5.0 by Great features Love this toilet. The comfort height is just that...comfortable. This toilet looks elegant in the powder room. Flush system is wonderful, and I am extremely pleased with this unit. August 27, 2013
Rated 5.0 out of 5.0 by This toilet is very attractive and would compliment any bathroom. This is my second purchase of this style. It is the comfort height which everyone should own. It is working great and doing what is suppose to do. August 27, 2013
Rated 4.0 out of 5.0 by One easy flush at the right height This toilet is the second one we have of this model. It looks good, bowl empties with one flush and we do not have to squat to use, nice comfort height. The tank lid is nice and flat with a slight rim so you can put items on it and they don't roll or fall off. May 7, 2013
