Hi all. I'm sure this question has been asked a million times over but I just wanted to be sure for my scenario as it seems like every rough in is different. Attached is a picture of the stack and the proposed bathroom layout. How does one plumb the wet side with proper venting? I will update drawings to verify.

So I think the drainage side is fairly simple, red is toilet, blue is tub and green is sink. Assuming I have to run a vent to the attic/roof from the sink, question is where do I vent the toilet/shower?

Here is a place to start, but I am not saying that will fix all. I am not a plumber.

You have to run your vents vertically until they are high enough before joining another pure vent. https://terrylove.com/forums/index.php?threads/plumbing-venting-system.61651/#post-456640 The yellow line in my sketch modification represents that.

45 degrees or steeper is considered vertical. That is the idea of my orange line: 45 degrees until high enough.

Maybe, but we won't know until we actually see HOW you are going to put everything together. There is NOTHING wrong with the upper vent line, so it does not have to be installed on a 45 degree angle, but you CANNOT tie the two lower ones together until THEY are 42" above the floor.

Hey, wait a minute.

This is awkward, but...
