Toilets that use the Unifit adapter come with the 12" rough, the one in the center.
You can also buy the 10" or the 14" adapter.
Since most of the toilets have 3/4" at the back, it would mean that a 9-1/4" rough in would work with the 10" adapter.
Since the bowl is so close to the wall, the water shutoff needs to be 7" to the left of center.
Toto does make black toilets.
