Soiree' and toilet flange height?

Hi All, I am getting near the end of a small bathroom reno and the tile floor is in and grouted. The toilet flange in the floor is now level with top of the finished floor. I am installing a Toto Soiree' toilet and I wonder if I need to get one of those flange extensions? I sat the adapter in place without the wax ring and it seemed to have very little play.
Thanks

You should be okay with maybe a normal wax ring, or certainly with a jumbo (which is a bit thicker). Many flanges are only about 3/16" thick, and if installed on top of the finished floor, any wax ring would work. So you are only talking about a small difference with yours flush. When you push it down with the wax ring, you should feel resistance as the wax squishes and conforms to make the seal. If it doesn't squish, it's not thick enough. The colder the wax, the harder it is.
