Off-white not white!
The color is off white not white as advertised. Does not match any other white item in the bathroom. Disappointing.

Hello AJJ, this is Laura with Kohler Co. I am sorry you are disappointed with the color of your toilet. Please call 1-800-4Kohler so we can look into this further to determine if the incorrect color was sent or the surrounding colors are affecting how the toilet color appears. We look forward to hearing from you to assist you. Sincerely, M. Laura K., Kohler Customer Service

      Quick Flush and Never Clog !
      This K-4198 toilet and K4468 tank is great ! It has never clogged and was tested under the same conditions as our previous toilet. Our plumber also installed a magical Kohler seat that closes slowly without slamming. Very Happy
