Install Toto Ultramax on 14" rough-in..

I installed the Toto Ultramax toilet last year on my master bathroom which has 14" rough-in..
I originally thought the extra 2" wont be a problem but now I am regreting the decision..
So, I would like to know if the Toto unfit rough-in adapter work on the Ultramax toilets..
If not, are there any other way to bring the toilet back closer to the back wall?

The unifit adapter only fits on toilets that are designed for it, so no. The Unifit is PART of the toilet...you can't install one designed for it without it, it isn't a generic part that can be used on any toilet.

You have three choices...live with it as it is, buy a 14" rough-in toilet, or move the flange and piping back 2". Well, you could build a box behind the toilet, too.

Jim's right.
It would have to be a Unifit model like the
Only TOTO uses the Unifit, and only some of their models.

Toto Vespin II CST474CEFG with SS114 Softclose seat.
This bowl was installed on a 13-1/2" rough-in using the 14" Unifit adapter.
The water shutoff can be as close as 5-1/2" to the left of center, unless it's higher off the floor, and then it can be even closer to center.
This shutoff had been replaced with a new 1/4 turn valve with brass nipple through the wall.

In some of the older Seattle homes, the old toilets had been wall mounted tank toilets.
Those typically are 14" rough-in and need a flange repair to use standard closet bolt connections at the flange.
Everything is on the truck for that.
