What does chair height mean? I'm seeking a toilet that is at least 18 inches to the top of the seat ( not top of the lid) Would be more helpfull if actual dimensions were shown.
Asked by: Frustrated
Hi, this is Laura with Kohler Co. I am happy to assist you with your question. Comfort Height toilets all measure 16.5" from the rim to the floor. Adding a seat would increase the height. Please work with your local The Home Depot for pricing and availability on this product. Thank you for choosing The Bold Look of KOHLER.

It was higher than the average seat but it is not exactly comfortable for me. I’m 5’8 and my feet doesn’t comfortably hit the floor. Some people may not have an issue.

Rated 2 out of 5 by from It Leaked We finally re-did our main bathroom; I chose this item because of the Kohler name and the color (which is very pretty). Our contractor installed it with no problem. Once it was used it began to leak. Our contractor looked at it and couldn't find where the leak was coming from - there were no cracks. It stopped and then leaked all over the bathroom (thankfully we were home and the rugs stopped it from reaching the cabinets); it began leaking again the next day. We removed it, returned it and went with an American Standard and although I don't have the Mexican Sand color, I don't have any more leaks. Also, we are not fans of the aquapiston flushing.
