Here is a pic of my new Kohler toilet, days after installing it. These pieces came out from the bowl, and I called Kohler to question their quality control. After weeks of fighting with them over the phone, they finally sent me a letter allowing me to order a new base from the orange big box store. It wasn't fun arguing with them and I did not appreciate their accusations that this was a 10 year old toilet and was due because of a lack of cleaning it.
