Kohler K-3979 Reviews

Rated 2 out of 5 by from Not my Favorite Great looks, perfect height, but I disagree that this toilet has "best-in-class" cleaning. The water spot in the American Standard Champion we had in our previous house made it MUCH easier to keep clean. I don't know if the spot was in a better position, or larger, but it was better in my opinion. I feel that either the water spot position, or the flushing action in this Kohler is less effective, and I, therefore find I am having to clean it far more often.

Rated 1 out of 5 by from Plungers Don't Work The toilet is nice and works great, very powerful flush except when it clogs. Due to the oblong shape of the drain a standard plunger will not fit over the hole so it is nearly impossible to use a plunger on these toilets. I would avoid buying one in the future.

Some toilets require separate draining devices, but this is not one of them! In general our site will always prompt you if there are additional items needed!

    The Kohler K-3979 has a bowl height of 16.5" tall. This does not include the seat, which will add another inch or so. This is an ADA toilet, which means it is going to be the tallest model.
