Installing new commode and was using an offset flange but it sets to high to install commode. Is there a low profile flange that is same hight as standard flange?

You will need to cut the old pipe lower to install the offset type.

What happened to the old flange ? Was it off-set flange, too ? Old commode fit OK and new one won't ?

There may be another solution to this. Post few photos from the installation showing pipe and old flange. Thank you
