We are faced with the dilema of an 11 1/4" rough in from wall. Prior toilet (Gerber) was a 12" with no space against wall installed by builder & plumber. We are now replacing old toilet & looking at the 10" rough in Toto toilets. Toto does seem to have the most variety of styles for a 10". I would like to know if anyone has used the 10" unifit on a 12" Toto without any problems. Can the unifit be used with a cast iron waste pipe? Thank You for any responses.
Toto for 10" rough in?

Almost any Toto can be installed at 11-1/4" from the wall.
You don't need a 10" in your situation.
The Drake only needs 10-7/8" and installs like any other toilet.
Your other questions:
Cast iron drains are fine.
Toilets that use a Unifit, like the Vespin, Carlyle, Soiree and others can use the 12" that comes with the toilet, or replace that with a 10" or 14"
Performance is the same either way.
Below is a toilet that does use the Unifit adapter.
The one pictured is the Toto Carlyle.
TOTO now has a 10" dual flush at the factory.
I'm bringing some here for the Seattle area.

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.
The Vespin comes with a standard 12" adapter or you can order a 10" or 14" adapter depending on your rough-in distance.

Thanks for the quick response but, we had already gone to Toto retailer. Unfortunately the sales rep did not make us aware that most Totos would fit on our rough in. I really wanted the Aquia or Nexus but purchased the Soiree because of it's rough in options, the style & the cyclone flushing. The 12" Aquia specs. show a 1/4 inch space between the wall & back of toilet. Would this toilet fit on our 11 1/4 inch rough in or is it one that wouldn't? What about the Nexus? Soiree can be exchanged as it hasn't been delivered yet. Thanks

No the Aquia won't fit, they are coming out with a 10" but won't be for a while.
Nexus is not available in a 10" rough-in, but the 12" can be pushed into a 11-1/4" rough-in.
I have three Soiree's at home and love them.

I think we're best off to stay with the Soiree. We have absolutely no luck & would probably run into some type of problem trying to push in the Nexus. Since we started the bathroom remodel we've not had one thing go right. We're definate candidates for "renovation nightmares"
