Our 20 yr. old toilet had to be retired and of course our only consideration was Kohler, which our plumber recommended.  It arrived ahead of schedule (not unusual for Wayfair), it was easy to install, and is a perfect addition to the master Bath!  The quality, fabrication and styles available along with the savings ($250 less than our local big box store for this model) was surprising.  How can you beat Free Shipping and the variety and quality of Kohler?
