I am renovating an old bathroom. I replaced the old toilet and after install the toilet is about 4" away from wall. Are the drains at the bottom of toilets different dimmentions or are they all just pretty standard? The flange off the wall is 14" to center

Yes, toilets come with different wall off sets. Most common is 12". Toilets that are designed for 10" and 14" off set are available, usually special order and more expensive. There is also off set toilet flanges. What kind of drain pipe?

The flange is metal or iron and I believe it is a 4 ". Thanks a lot for your answere

Harold is correct about the different set backs for toilets. If the tank is 4" off the wall you bought the wrong toilet for your situation. Also, 14" of the side wall is just an inch away from meeting code. Hope you will not need an inspectiondown the road, this will not pass.

Moved to plumbing (Thanks Chuck)

Are you saying you installed a 10" rough in toilet on a flange 14"off the wall to center leaving you with 4" from tank to wall?
You have two options. You can purchase and install a 14" rough toilet or you can install a 2" offset toilet flange, **or** you can move the closet bend and flange back to where it belongs. Good luck in whatever you decide on. Tom
