Hello,
I'm new to this forum. I am putting in a wet bar sink in a kitchen area. The sink backs on to a wall that already has plumbing for a bathroom sink that is on the opposite side of the wall. I was hoping to share the drain/vent of the existing bathroom sink. I have a picture of my plan to modify the existing drain/vent. The sinks are within 30" of each other.

Will this work? Thanks in advance for any input.

It should work, vents are supposed to be within 5' of the drain. Just make sure that you have a decent slope in your now drain (1/4" per foot) and that any Tees are angled in the right direction for drainage.

Thanks for the feedback.
