I'm installing a vanity and sink in my bathroom. Is there a standard
height for the drain pipe? I mean the horizontal pipe that comes out of
the wall. Any links to information would be greatly appreciated as well.
I don't recall a Code requirement for a specific height,
but 18" off the floor would be typical.
Sounds like you are doing a DIY drain install.
Suggest getting a basic Plumbing book because
there are numerous issues involving the plumbing
behind the wall.
The 18" sounds about right, but do this. Place your sink across your
cabinet. Put the tailpiece with popup on the bottom of the sink. Now
screw the trap onto the bottom of the tailpiece. Now measure the
distance from the output end of the trap (piece pointing toward the
wall), to the floor. That's about the height for your vanity.
However. remember you can easily saw off a little of the tailpiece,
but be sure you dont get too high or the trap will be above the popup
lever. I actually ran into that once. I'd rather put the wall pipe
too low than too high. You can always add an extension, you cant
install a trap that is too high. Keep in mind if someday you install
a deeper sink too.

When roughing in same in new construction we always set to 16" for sinks 12"
o/c setback for toilet flanges, etc., that way next guy into project does
not have a heart attack as all is standardized.
Besides, good chance next guy doing install will be you.
