Tight quarters toilet recommendations?

Howdy, all.

I'm remodelling our upstairs bathroom. For reasons that I don't understand the toilet is placed opposite a chimney (from the hot water/boilers in the basement); thus, we only have 44" from the toilet-side wall to the facing wall. As you can tell, this is pretty short.

The drain is constructed out of a massive cast iron fitting that is shared with the shower and sink drains, so I can't move it. Instead, we're looking for a short toilet. What we have now is 26.5" back to front; most modern toilets seem to be 28" or so and that's too much of a squeeze. So, I'm hoping someone can point me in the direction of one that would work.

Requirements:
* Short as possible; round front is okay.
* 14" rough-in.
* Dual flush is a bonus.
* Not tremendously expensive is also a bonus.

I've been looking at Toto obviously, but again most of what I've seen is 28" back to front.

Thanks!

I just went through this same process and the toto unifit's will be the shortest you can find at 28 3/4" from the wall.

14" rough-in for toilets. Which models take up the least amount of space?

Sometimes a bathroom has a non-standard dimension for the toilet rough-in. Standard is 12"
Sometimes you will see a toilet roughed in at 14".
You can always use a standard 12" rough toilet for this, but the bowl sets out from the wall an extra 2"
You can order thicker tanks from some manufacturers, that hide the fact that the bowl is setting 2" farther out, but the end of the bowl will still be out in the room.

There is one manufacturer that "moves" the bowl back 2".
You pay more though for this advantage.
Models from Toto that allow you to move the bowl back 2" with their Unifit adapter are:
Vespin
Carlyle
Carrollton
Carolina
Lloyd
Pacifica
Soiree
Guinevere

With the Vespin and Carlyle, the shutoff can be 7" to the left of center.
With the Soiree and the Guinevere, the shutoff can be 5-1/2" to the left of center.

Most of these are 28" long and set off from the wall 3/4"
So on a standard 12" rough, the end of the bowl would be 28-3/4"
If you have a 14" rough, you can switch for a 14" Unifit and keep the distance to 28-3/4"
The 14" Unifit needs to be ordered in addition to the toilet.
They come with the standard 12" Unifit, which winds up being an extra part.
And no. I don't need anymore 12" Unifit adapters.

So to explain how this works:
Cadet 3 14" rough "round bowl" is 30-1/4" from the wall.
Cadet 3 14" rough "elongated bowl" is 32-1/4" from the wall.
Any of the Toto toilets above will be about 28-3/4" from the wall with the elongated bowl. Shorter then most other round bowls, and much shorter then the other elongated bowls.

You pay more, but get a better toilet, and more usable space in the bathroom.

Your call.
