Hi Everyone,
I am a non-professional looking for good advice on a bathroom I am plumbing. Thanks in advance for your help. I would appreciate hearing other, better, approaches to this half-bathroom
It is a small first floor bathroom with some tight quarters and I am having trouble fitting everything in the small wall I have to work with. I don't have easy access to the exterior wall. So far, the best solution I've come up with has a 180 turn for the toliet, which I'm not sure is kosher. (A drawing is linked to below)
The toilet elbow is connected to a 3" long sweep, which is then connected to a 3" combo wye, laid horizontally, to connect with the main drain. The wye and long sweep form the 180 I'm worried about. just downstream is a 3" x 2" combo wye, oriented vertically, to vent the toilet. Just upstream from the horizontal combo wye is a vertically oriented 3" combo wye that receives the vertical drain for bathrooms above. Upstream from that wye, the drain reduces to 1.5" to drain the bathroom sink.
Incidentally, another question I have concerns the best way to reduce from 3" to 1.5" for the sink drain. Can I bushing right off the vertical 3" combo and use a 1.5" elbow, or should I bend vertical with 3" before the bushing?

can you put the toilet on the right? you can use the 2 inch toilet vent to drain the sink into at 18-19 inches above the floor.
i can not read what you wrote behind the sink???

We thought about moving the toilet to the right, but this would mean switching places with the lav. The door is currently next to the lav, and we thought it would be weird if you opened the door and the toilet was before the lav... backwards to the typical bathroom
It says 1.5" drain behind the lav

now that we have cleared that up... the toilet vent must be between the toilet and the main drain you are tieing into. as drawn the flushing water from upstairs can syphon the toilet.
can you flip the toilet and lav so they are on the opposite wall and shift the door? this would make the DWV much simpler.

Thanks for the advice. I think I found a solution which solves the venting and 180. How does this look?

you will need to vent the lav. as i said, if you drain the lav into the toilet vent it becomes a proper wet vent. the vent must be 2 inch and remain 2 inch.

Thanks Packy,
I've got the lav draining into the main drain well downstream of the toilet, and I plan to connect the lav vent to the toilet vent in the ceiling joists above the bathroom. I think I will have to 45 around the main toilet drain to do so. Greatly appreciate the advice
