13.5" Rough In

Hi - I'm installing a new Toto Ultramax and my rough in is 13.5" from the wall. Can I use the 14" Unifit? I believe the standard depth behind the toilet is 3/4" so in theory I should have 1/4" from the toilet to the wall. Any issues with this?

This actually would be good as I need all the room I can get for the door to close, otherwise I'd have to go with a round bowl.

Thanks for the advice!

The Ultramax doesn't use a Unifit adapter.

The Carlyle will use one though.
Just make sure with the Carlyle, that the water supply is at least 7" to the left of center.

Sorry I meant Carlyle, not Ultramax. Was just staring at the Ultramax before creating the post. So other than the 7" requirement for the water supply I should be ok.
