The Unifit adapter

The skirted toilet design offers the use of a patented modular rough-in system, which has been popular in Asia, called the UniFit Rough-in.  The system includes an interchangeable part that replaces the lower half of the trapway, adapting the toilet to either a 10", 12", or 14" rough-in. 

Only TOTO uses the Unifit, and only some of their models.

Power Solutions

  • Adjustable unifit trapway
  • Powerful flush using a 3" flush valve system
  • Extra Large Shaped siphon jet
  • Large trapway that has been computer designed
  • A good replacement for pressure assist toilet, 3.5 GPF toilets and other low flow toilets.

They recommend that the water supply be 8" to the left of center, however, for the Vespin and the Carlyle you can get by with 7" from left of center and 5-1/2" for the Soiree and the Guinevere.

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

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.
