14" Rough-In?

I've been doing a lot of research on this site because we desperately need a new toilet to replace the old AS one that's there now (and no telling how long it's been there). I just discovered the thread that discusses how to measure rough-in. I measured from the wall to the toilet and it's 14"! We're pretty sure we want to purchase the Dartmouth--is that possible???

Thanks very much for any advice you might have.

Yes, you can use that, but you'll end up with an extra 2" of room behind it. If that's an issue, one of the other Toto toilets that uses the UniFit adapters would pull the toilet back to close to the wall. It comes with a 12" adapter, which you'd throw away, and have to buy the 14" one. Search the toto site on unifit, or 14" rough-in, and you'll find the models that use it.

Thanks, Jim.

This site indicates the following:


Q: I need a toilet that will fit a 10" (14") rough-in. Which one will work?
A: If you have a 10" or 14" rough-in, the only TOTO toilets that will fit are skirted (smooth along the sides) NOTE: The TOTO Nexus and the TOTO Lloyd only fit a standard 12" rough-in.


Does this mean that in order to use the unifit for the 14" rough-in, the only type of toilet I can buy is a skirted one?

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.

Thank you, Terry, for taking the time to give such a detailed response.

The current toilet tank sits about 3" from the wall. We don't want to spend upwards of $1000 on a toilet, so some of the options you listed are out of reach for us. Of the less-expensive versions you listed, the Vespin and the Carlyle appear to have the best ratings (at least, on this site):


Another thought: If we don't mind the toilet being 2" from the wall, would a Dartmouth, Promenade or Drake work for us?

Thanks so much.

I don't know how the other site rates their toilets.
Most of them have never installed a toilet.

Here's a little secret about the Toto toilets.

They use the same flush valve and same trapway design.
They only thing that changes is the style.

I've seen some ratings that vary a bit on paper, but in real life it all evens out.
The testing isn't very real world.

The real facts are that the trapways are similar and they use the same 3" flush valve, and have for over 10 years.

Any Toto with the 3" flush valve is going to work well.
All Toto toilets have Superior quality control.


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.
