View Full Version : Rough-In and Supply Line Problems

05-07-2010, 08:40 AM
I am replacing two toilets and need help. The supply lines and rough-in look as if they will give me problems.
The first one has a rough in of 10 in. with a supply line that has a 5in offset from center line of stool and comes out of the wall at 8in high. Is there anyway the Drake II will work with the 10 in rough-in?

The other bathroom has a rough-in of 14in., but the supply line comes through the floor. It is 8in off the center line and 4in from the wall. Do you think the Vespin II will work in this case.

Easy fix for the supply line problem. Just redo the line. The best way to handle the other two toilets is one of the Toto toilets that use the Unifit adapters. There was a recent thread dealing with this in this forum's section. There are several models to choose from. You would have to purchase a Unifit adapter separately for each of them as they come with a 12" adapter only. This would fit the toilets properly in the room. No other manufacturer has this kind of toilet. The Drake will not fit a 10-1/2" rough-in.

I look for and found the thread I referred to and have copied it to this reply. I think it will give you the information you need. This was an answer by Terry Love to a question similar to yours.

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.
