Kohler K-4644 Reviews

Rated 5 out of 5 by from Small Changes make the differences I purchased toilet seats for my house since it has been awhile since they were replaced. As I move room to room, a little paint, decorations and changes to fixtures can dress up a dull environment. Nobody should brag about a toilet seat, if you do I don't want to ever meet you, but often times little visuals around the house can be enhanced by simply replacing them. The seats are inexpensive, good quality and simple to install. In this case you get what you paid for and worth it if you need replacement.

Rated 5 out of 5 by from I bought this a month ago and I'm glad I did! It was easy to install, it is made well, and sits well!

  • Do you have a Kohler Rialto 3420 TENDER Grey (note: NOT "Thunder" Grey) toilet seat? If not, is Ice Grey very close to Tender Grey?

    A. The Kohler K-4644 is no longer available in tender gray. That was discontinued. 4662-56 is in tender gray and one of the only ones still available. You can reach me by email or directly on ext. 341. Have a wonderful day and happy home improving!
  • what is it made of?

    A. The Kohler K-4644 is made of polypropylene.
  • what are the measurements of the lid. My old lid measures approx. 15.5 X 13.5 inches. Will this model fit mine?

    A. The Kohler K-4644 is 15-13/16 inches long from front to back and 14-3/16 inches wide. It is meant to fit all standard rounded bowls. I hope this helps!
  • Can you tell me the difference between Kohler 4644 & Kohler 4775 ?


    The difference between the 4664 and the 4775 is that the 4664 is a thicker seat at 1" vs the 4775 is 3/4".
