If the 1 1/2" pipe doesn't go up the wall then what about outside? Anything there?
You have no idea where that 1.5" pipe goes to in the floor? You might tie it into the shower line with a wye fitting.
The vent pipe in the ceiling will need to be tied into.
Have you run everything in the home to find out if any of it goes to those two pipes?
I am thinking of tying it into the old 1 1/2” lav drain right by the main drain as I will no longer use that. Do you think that will work?
Nothing outside either, so I am quite confused as to what that is supposed to be.If the 1 1/2" pipe doesn't go up the wall then what about outside? Anything there?
I vote for tying it into the old lav drain, as long as it doesn't interfere with the 2" for the new lav.
I don't see a problem, but I could have missed something. Consider a 4 x 3 closet elbow to feed the 3 inch pipe. That accepts either an outside 4 inch or inside 4 inch closet flange. However since you are selecting an offset flange, maybe that 4x3 would not fit for you. What offset flange are you looking at? Would a 45 degree output flange work instead?
How about Sioux Chief 889-AOM or Oatey 43606. They are full diameter, and have a stainless steel flange.this is the offset flange I was thinking of using. Is this okay? View attachment 60968
Yes. Not that plastic will not usually survive, but the stainless ring should be more durable.And it is better that it has a stainless steels flange? For the toilet to be better secured? Is my understanding correct?
For the 4x3 closet elbow, yes.
Yes. Not that plastic will not usually survive, but the stainless ring should be more durable.
I wonder if this could work better for your routing situation:
Oatey 436662 Or Sioux Chief 889-45AM

I’ve made a new drawing of how everything will be connected based on the drawing from Terry in page 1.
would it be possible to obtain feedback if this is correct? Thanks!
Please ignore the 2 22.5 degreees 1 1/2” connectors. The ceiling coupling should say 1 1/2” x 2”.

I find that top section drawing is confusing. A little like a Picasso, but not nearly that bad. A sanitary tee that carries drainage always is in a vertical plane with the side port horizontal. In your drawing, the output of the trap passes horizontally through a 45, and then gets to the fitting in question. The side port of the fitting points up, and has an AAV on it. I think that needs to be a combo fitting which is the combination of a wye and a 45. Not a santee. There was a time where a santee on its side was the norm there, but not now. After that vents, the line can continue at 1/4 inch per foot downward or more.In the top part, the 2x2x2 above the toilet flange. I have it noted as a wye, should it be a wye or a sani tee?

The middle makes more sense, but it has some weirdness. The output of the p-trap is the trap arm. The trap arm needs to go horizontal (dropping at 1/4 inch per foot) until it gets vented. So I think the fitting there should be a santee, and the trap arm should go horizontally into the santee side port. The trap arm path can go through a horizontal long 90 on its way to the santee. There is a maximum length for that path from the U of the trap to the santee.
That dry vent for the shower should not go horizontal. If you could bring in a 2 inch pipe from a lavatory to do wet venting, you can come in horizontal. Is that top left 1-1/2 inch from a lavatory? That would simplify things potentially. I don't know if you would have to increase the size of a wet vent in Canada to 2 inch. With UPC you would, and IPC, I am not sure.- on the middle (wye part) goes horizontal, and then 90 degrees vertical to connect to the vent/sink drain (middle part)

For the dry vent, can you put the combo at/in the wall with the side port vertical, and run the drainage from the shower through that? 45 degrees or less from actual vertical is considered vertical.
Yes. The wet vent can go horizontal. The dry vent cannot, assuming the rules in Canada are similar to UPC in that regard.so the 2x2x2 wye bring in venting for the shower along with sink drainage via 2” pipe. Can it go horizontal for approximately 6 inch before it goes vertical into the wall, or will it have to have it go vertical right away?
Yes. 45s are good.I could achieve that with 2 45’s instead of the one 90 degree. Does that work?
This is awkward, but...
