No, the one that was previously installed in the other bathroom was a definite 12 inch rough, and I bought a Kohler Cimmaron which the plumber brought and installed after I had picked it out. At any rate, I was wondering about it, if I could buy the toilet and have it professionally installed, but didn't know what size to buy, but have decided to have the plumber deal with it completely now. I got some really good information here, and I appreciate all who answered.
