Rated 4.0 out of 5.0 by sweetvarmint Great toilet
Great toilet! Have others like it in home. Only this one came with a slight problem, otherwise would have been excellent quality. Flapper wouldn't float on water long enough to fully flush. Had different type of flapper than others in home. Replaced flapper, no problems. Love the low profile.

Rated 1.0 out of 5.0 by Brioche 2006 Rialto nothing but trouble over the years
We purchased this toilet in 2006 for a small bathroom in our 1930 house. It fit well, and looks great. Within a couple of years, a valve in it started clogging up regularly. Every couple of months (or when the toilet stops flushing properly) we remove the tank lid and flush this valve by hand (Kohler gave us directions over the phone). It's a nuisance. The toilet seat has worked loose and shifts and is noisy. The toilet sprays water during refilling of the tank. This water appears outside of the toilet- running down the front of the tank and wetting the adjacent wall. To stop the spraying, we turned down the water pressure. Now the toilet refills at a very slow rate. About a month ago, it started running after a flush unless you give the handle a sharp jiggle at the end of the fill cycle. To prevent the running and waste of water, one must hang around until the tank has slowly refilled. It's so exasperating!
Why does a toilet that looks this great and has good flushing power have such cheap plastic parts that it repeatedly malfunctions over 9 years of use? Older toilets used to work for decades before problems developed.

In our small bathroom, the Rialto adds sophisticated style and space.

Rated 5.0 out of 5.0 by Gizmette Handsome Toilet...as Toilets Go
This is a good looking toilet and although not as efficient as others, was purchased at a good price. The first one came in broken, and it was a scramble on the phone to get HD to figure out how to get another one to us.

Rated 3.0 out of 5.0 by DrO Sluggish flush
The flush mechanism is sluggish and the toilet must sometimes be flushed twice to completely clear the bowl..

Rated 4.0 out of 5.0 by KohlerMan Flushes very well at 1.6 gal. fit Very well under existing counter cause it's a very small unit.
Received with a missing important part. My plumber intalled a replacement flush kit just to make it work. After that everything worked great. This is a small bowl. Small seat and low to the floor. Just what I needed. This is a very heavy well constructed toilet. One small rubber white fill tube was missing so the bowl would not fill but my plumber replaced the flush mechanism with one he had on his truck (Thank Goodness).

Rated 1.0 out of 5.0 by DosSloan Horrific product. DO NOT PURCHASE. You will thank me!
In 2006 our baths were remodeled & this product was installed along w/2 Toto Drakes(both superlative products). Due to the low height of the tank the designer recommended it for our child's bath. I had read the Rialto reviews & had serious reservation however the designer assured me her clients were pleased w/the toilet. Sadly I permitted its installation-something i seriously regret!
Unlike the 2 Totos, which have NEVER clogged, I have repeatedly had to ;unclog my child's toilet, & not because of excessive use of paper. I have also used it & had it plug up on me! The size of the trap is simply too small, clogs frequently, & toilet has weak flushing power. I've told my child to go potty, flush then wipe & flush again. Absurd! My mother in law managed to plug, flush again, & overflow it. Additionally the flapper design is inferior. The toilet has began leaking water-unlike the 2 Toto Drakes which still have the original flappers from'06, & as others have mentioned, replace flappers/parts even from Kohler do NOT stop leakage resulting in wasted water & higher water bills.
Finally the bowl has less use the the 2 Drakes yet becomes filthly & requires more frequent scrubbing. It s/b noted that the Drakes do not have Sanigloss, something I wish I had order, just the standard finish.
After 10yrs I've sworn never to purchase Kohler & am going to order a Toto replacement & donate this toilet to charity.
The Rialto is an inferior, NOT recomended, product.

Rated 2.0 out of 5.0 by agomong clogs easily, doesn't flush well, lasts only about 10 years
we have this toilet in 3 of our bathrooms. we chose it because of its sleek look and smaller size. it clogs very easily and does not have a strong flush. we literally have to plunge it a few times a week. when we go away on vacation and use american standard toilets, we never have any issues! we've had them for about 10 years and they are all starting to malfunction. we will be replacing them with american standard. never buying kohler again.
