Putting in a basement toilet (hasn't been purchased yet). The center of the toilet drain from framing is 11 3/4", sheetrock not up yet. I know 12" is standard. My question is can I still put a 12" on center toilet in? Is there enuff slack there or am I going to have to go with a 10" toilet?

I think you will be okay----before you buy the toilet---measure up the model that you desire---most brands have enough 'wiggle room' for your opening---

the old american standard cadets would fit on an 11 inch rough. some brands would and other wouldn't. that was before all the 3 gal or less toilets.

As the above member says, you may be able to, depending on the thickness of your sheetrock and the toilet you choose.

A lot of toilets say in the spec sheet if it will be possible. You can find the spec sheets on the manufacturers' websites.

Here's an example, the Toto Drake II:

I installed one of these recently. The spec sheet claims there's only 5/8" of space behind the tank, so it would be a very tight fit or not fit in your situation.

I just had to fix a couple of flanges due to H.O. wanting to add Tile behind the toilet halfway up the wall "Wainscoating".

Looked in the Kohler R.I. book for the toilets which said @ 12" from finished wall, we would have a 3/4" gap behind the toilet.

So, basic math in my head 12" - 3/8 tile - 1/8 thinset = 11-1/2" > 11-1/4" which should give me 1/4" to spare which isn't much, but for a 1 piece toilet it should be a no brainer. :whistling2:

We set the actual toilet against the sheetrock, measured 12" to center of bolt holes, tried to slide one of the tiles behind it and it wouldn't even fit.

Rough in specs are not always what they're cracked up to be. :jester::jester::jester:

If you can fix the flanges, do it, otherwise you may end up with a toilet you can't use.

They do make offset toilet flanges if that's an option for you. Can't sneak the piping over a smidge?

Go to home depot and ask for a toilet that will work- then have the salesperson line up the toilets against the wall and measure them. This will serve two purposes- You will find the toilet that works for your dimensions and the salesperson will now have gained a little knowledge about plumbing :thumbup:
