we just had a Toto Aquia dual flush installed and it's so great we want to put one in the other bathroom. the problem is that bathroom (the original in this 1936 house) has a 14" rough-in.

so, is there a dual flush with a 14" rough-in or should we use the Aquia with the 12" and put in a "backing" (which is what the plumber said is an option)?
btw, what exactly is a "backing" -- is it any piece of wood to bridge the gap or is it something specfic for toilets?

thanks

There is no reason to block behind any toilet.
If you have a 14", that just means there is 2" more inches behind the toilet. No harm there.

does that mean there is not a dual flush with a 14" rough-in
or that you would recommend the Aquia with the 12" rough-in and just leave an extra 2" behind it?

thx

Most Toto Uni-fit's are available in 14" but Aquia is not.
The backing would be a extention of the wall and it would look nicer than a 2" gap behind the toilet.

I dunno, a gap means you might be able to paint back there without pulling the toilet...all a matter of choice.

I'm with jadnashua! Since having the closet bend replacet from lead to pvc, I some how went from a 12" to a 14" rough in. I am just going to put in an Ultramax and forget the gap.
