Why not just offset the trap arm, inside the cabinet, instead - leave the dwv where it is?
Yes. You have to keep at least 5/8" away from either face, and the hole to a maximum of 60% of the stud (on a 2x4, that's 2-1/8"). If it's a bearing wall, 40% (1-5/8").Any concerns with drilling through the 4 studs? Thanks.
Offset's starting to sound like a good idea, am I right?
