Toilet rough-in question
 
I'm moving a toilet to a location that can't quite get 12" center rough in from the wall. My 3" pvc line can get to about 10 1/2" - 11" before it's blocked by an obstruction in the floor.

I see basically every toilet is for a 12" rough in. Is there enough wiggle room to get away with using one of these on a 10 1/2" or 11" rough? Or is 12" pretty exact and wouldn't work?

You can get toilets for 10.5" rough but they cost more. Try google.
A standard toilet needs about 12" rough in minimum. Anything less is a pain or won't fit.

Are there disadvantages to 10" toilets? Do they have the same flush power?

Also, I've seen offset flanges. Would that do anything for me?

10" toilets are basically the same. The bowl is the same and the tank is a little different. IMO, I'd avoid an offset flange if possible. I find them troublesome. The toilet will cost a little more but is no less of a toilet.

Ok, good to know. Thanks. I've also been reading that there are lots of 12" rough toilets that leave a 1"-2" gap to the wall. So maybe when it comes time to install, I'll see if a 12" fits nicely, otherwise return it and go with a 10".

Some 12" toilets will fit. I just didn't want to make that recommendation and cause you grief when a particular one wouldn't fit :wink:

:thumbup:

Seriously though, some of the gaps behind these 12" rough toilets are ridiculous. I had one before that was almost 2" w - t - f ??? :eek:

Keep in mind that you do have some wiggle room on the flange, and the slots in the toilet, but thats 1/4 - 3/8 at most from front to back.

Ok. I think I'm gonna try the 12" first and see if I can fit it, otherwise I'll go with the 10". I prefer to have as little gap as possible anyway. Thanks guys.
