Pipes in crawlspace

Hi my friend ask me to post this cause he doesn't have an account:

I am thinking of recessing my medicine cabinet directly above my bathroom sink, but Iíve been told that there is a possibility that the pipes for the sink run directly up into the attic. However, my bathroom is over a crawlspace, and from what I can see in the crawlspace, I see piping right underneath the sink.

Is there a possibility that pipes still go up to the attic if a crawlspace exists? And will a stud finder be able to find a pipe? If I know the distance between studs, I can be pretty sure that something in between is not a stud.

Or should I simply venture into the attic and try to find some pipes? I think that itís doubtful that a builder would run overhead pipes, then shoot them through the walls through the studs.

I would guess you probably have a vent pipe heading upwards from directly behind the sink. I don't believe a studfinder would identify this...

The pipes in the crawlspace would be for drainage - the venting pipes would go upwards......

If you go into the attic, you should be able to identify your venting system...

Good Luck
