After having torn up some of my basement slab, I now have several more quandaries for which I am looking for answers. They are related though.

I find that the area in which I would like to locate my commode is approximately 14 inches horizontally from the waste line that is already installed under my slab. The existing line is also only about 6" from the top of the slab to the top of the pipe. Herein lies the problem(s). I'm not sure if I can install a toilet flange directly onto a 90 degree bend (or even if it's a good idea), and if I do (using a standard flange and 90), the top of the 90 winds up about 1" BELOW the top of the existing waste line. Do they make any shorter flanges or fittings for this situation? The only solution I can see with the fittings I have is to move the commode almost directly over the existing line - but that would put it right in the middle of a small area I'd like to make use of. Anyone have any ideas? Thanks!

Then I wouldn't use a 90 degree bend. Consider using a street closet bend . Good luck, Tom

The problem with the street closet bend (I'm assuming that's the larger sweeping 90) is that it has an even larger dimension that would put it even lower than the standard 90.
