I purchased 2 of the Toto Carlyle II toilets, but not yet installed. On their spec sheet, it allows for the 10, 12 and 14" rough ins. The Carlyle is also skirted, but doesn't have the dual flush. I had found good reviews on the toilet, but many have warned that the Carlyle requires 7" from the water supply. Hope this helps.

Go to this page and scroll down:

and there is a list that mentions some of the toto toilets that take the unifit.

And go to this forum and scroll through the topics there are more than a few threads on this topic.

good luck.
I have a 16" rough in and am looking for a skirted toto that takes the unifit.

Vespin II (essentially the same as the Drake II but skirted) can take a Unifit for a 14" rough-in. To see if a Toto model accepts a Unifit, go to www.totousa.com and click on Products --> Toilets --> (model you're interested in) --> Downloads & Resources --> Installation Manual --> (list of model numbers). The PDF file with installation instructions will show if a different-rough-in Unifit can be installed on that model.

Yup. I have 2 of the vespinII skirted. They are unifit adaptable.
