    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:

    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.


    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.
    Installation was by James Love of Love Plumbing & Remodel 206-949-5683
    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.
