We are remodeling the bathroom, moving the sink and bathtub (originally a shower). The shower and toilet were along the same pipe line and vented in a privacy wall next to the toilet. The sink used and AAV.
I can continue to use AAV in the new sink location or tie all three into the same vent (if possible). All three walls that could be used for venting are structural walls and cannot be used for venting (as far as I know). The one internal wall has a triple joist beneath it so cannot be accessed directly.
Based on my image showing the placement of the sink, bathtub and toilet, along with the existing plumbing locations, what are my options for venting? Am I able to vent with just one vent? Will I need two separate vents? What locations are available to me that don't require the privacy wall? I figured the shower would have to be vented in the adjacent wall by the drain, but I'm unsure about the sink and toilet.
If I doubled the thickness of the wall behind the toilet (added another 2x4 wall) I could vent in that "false wall", but it would visually look odd having just that section twice as thick as the section on the other side of the door.
Any options and advice are welcome! Thanks!

Thanks for the reply Greg. I was already planning to vent the toilet and tub through the roof. The question I really need help with is how to get it there. Bases on my setup I'm not sure how to achieve it, in particular on the toilet. I
Because of the load bearing wall setup, is it possible for me to reach the roof without having to build a false wall to hide the vent pipe? And finally, is there a way, based on distance and direction, to vent the tub and toilet on the same pipe?

Depending on your outside wall thickness you may be able to go right up inside the wall with 1 1/4 or 1 1/2 pipe then through the ceiling & roof. You really don't need a straight shot, just enough to get the pipe through and air into the drainage system.
