Can you use flexible rubber cuppling at bathroom sink drain? Photo

Found in a home that was just "remodeled". I don't think this can be used here but I can't find a code reference for it. So, take a look and let me know, please.

Drain sets have reducer compression nuts to go from 1-1/4" to 1-1/2", not this type of coupling/adapter for this application. I don't know who did the remodeling and what he was thinking.

The drain is either too high in the wall, or the installer didn't know how to cut the drain tail piece shorter.
I've never seen a drain so "hacked" in.

I would love to see the entire drain all the wall to the wall. I can use a laugh today.

It comes under the classification of "good workmanship".
