bathroom-fixturesplumbingsink
I have my bathroom sink rough plumbing coming from the 3" stack vent, running about 2 feet. My question is: can I use that same drain line for another sink?
Reasoning: about 2 feet from that sink drain I have a wet bar sink I want to put in. Using the same drain line sounds easier, only because of where the stack is, not because of putting in the second trap.
OK as a temp fix you could:
What you want to do is run the p-trap parallel to the back wall within the space between the wall and the back of the drawer.
If there is adequate space, start with a wye directly onto the pipe as it comes out of the wall with a line cleanout glued into the end of the wye (if there isn't enough space, use a 45 elbow). Use a fitting 45 or regular 45 elbow (again, depending on the available space) into the side outlet of the wye, then a short piece of pipe and the p-trap. Now you can go vertical along the back wall, then use two 90 elbows to offset to the sink's tail piece.

Consider all the dual-basin kitchen sinks... "If it happens, it must be possible."
