Hello, I am attaching a picture in hope that someone may suggest a better venting option. Or, tell me it is ok and I will proceed. The walls are exposed at this current time. Thanks and waiting for your response.

Is the tub/shower and sink vented? If not you need to vent them then turn our attention to the drains.

OK, no only the old original 4 inch stack, now, what about the drains??
This house is a 150+ year old home. I switched the tub for the sink so far. Everything seems to drain ok, but the toilet has never worked properly.

Thanks 4 your time!
 
make a drawing showing the vents for the sink and tub shower.
 
It looks like a toilet flange and arm that is vented.

Then you added two more fixtures into it.

Cut below the tee for the toilet and add a wye for the lav and tub.

The lav and the tub will need their own vents, which can be tied together at 42" above the floor, and then out through the roof.

Terry below which tee? Any code for Canada about two vents out the roof?
Thanks for your time and expertise, I want this bathroom finished up!

The 4x3 tee in your drawing.

There should be another fitting below that for the other fixtures.
It would be something like a 4x2 on the vertical.

You can have as many vents going through the roof, as you do fixtures.

You can also combine them into one above the flood level of the fixtures. Normally 42" above the floor, or in the attic if thats easier.

The type of ceiling is immaterial, although cathedral ceilings can create problems trying to run the pipe at the correct angles. You "unglue" ABS and PVC pipes with a saw and new fittings.

Hello, thanks for your reply.
I understand abs, I was wondering how much or type of heat to disconnect cast iron fittings.
Thanks, di
