I have new plumbing installed for a new toilet. However, the 4" pipe is too close to the floor so the toilet flange (not yet installed) is too long and sticks above the finished floor about an inch. The pipe can't be lowered due to space issues. Is there anyway I can install this flange (or a different one?) that would make the flange lower and flush with the floor or, although not ideal, sitting on top of it? Also should mention that the pipe does not go straight down like the picture makes it seem. It is an elbow right at the floor.
Here is a crude illustration of the floor and the issue with the flange.
