Obviously there are details to figure out, but am I on the right track? Thanks!
Check a rough bath plan, please

Would I have a better chance of getting some help if I simplified my question a bit? I realize this is asking for a lot of help and there is probably a lot wrong with this...

The shower gets vented before entering a line with the toilet.
The toilet needs a vent before the washer hits that line.
The washer can't wet vent anything.

Thanks! Probably a dumb question, but is the red vent here not a dry vent? I thought it was since water would never pass through it. Pax.
Where is the washer coming in? Downstream? Or? I can't tell what the intention is.

Say the washer comes in right below the red vent.

No, I think I see now that the washer has to come in below the shower, otherwise the shower's vent is a wet vent with a washer on it, which isn't allowed. Right?

Here I think I've fixed the washer drain. Does the 1.5" vent on the small lav count as a wet vent for the shower? Or do I still need to vent the shower?

I still need to vent the shower, because you can't have a toilet upstream of a wet vent (I think).

Okay, (fingers crossed), this looks like I maybe fixed everything...

1. Orient your floor plan so it's going the same direction as your plumbing plan. Include ALL the fixtures and LABEL them properly.
2. Draw a dotted line on your floor plan where the existing drain line is that you intend to tie into, also size.
3. Is this on the first floor?
4. What material is the floor made out of? crawl space ?, concrete ?
5. Can a vent go through the roof anywhere on your floor plan?
If you do this it's a lot easier for people to help you.

Thank you! That's exactly what I needed... I'll make some better drawings now.

Quick answers to your questions (with a better drawing soon):
This is a second floor addition that will drain with 3" pipe down to the main floor bathroom drain, connecting into a 3" stack. The second floor addition is not directly above the main floor (it's above an added garage adjacent to the first floor bathroom). The fixtures on the first floor were vented through the original waste stack, but I'll separately vent them through the roof. Both floors are plywood on joists. The main floor is above a finished basement and has 2x10 joists. The addition is above a garage with tall ceilings, space isn't much of a problem. Yes, the vent can go anywhere through the roof on the floor plan.

This perspective view has the same position as the plumbing plan, so it might make things a little clearer... but I'll still try and improve the drawing.

Are you planning on running the drains under the floor joist's or inside them? If your planning on running them under then it's a walk in the park.

That's what I want to hear! They are going under the joists for the addition. The pipes on the main floor will stay between the joists, but there isn't much to do there. Pax.

I'm an over builder too. Does 3" make it drain appreciably better or just decrease the chance of a clog?

I just thought since your washer is on the second floor you don't want to take the chance that the drain won't keep up with the washer discharge.
But it's your call.
