Hi guys. I'm changing a tub to a shower and came across an issue I'd like to run by the professionals. The vent protudes out of the wall (which was hidden by tub) in a bad spot. I'd like to move this protrusion to the right right of the picture (below). The new protusion will be hidden by an enclosed triangular foot rest that my wife conveniently wants there anyways.

My concern is the method I use to move the assembly. As you can see a 2 inch toilet drain comes from the left and then connects to a 2x1.5x1.5 tee. The center of the tee is the vent and the right side is the tub drain. If I move it to the right, the most convenient method would involve the vent being the right side and the drain in the center. Does it matter what order?

Also, is it a problem to move the vent farther away from the toilet drain? Right now it's 4' and moving it to the right would make it 5.5'.

You can't have a horizontal dry vent below the floor. You need the trap first, then a 2" X 1 1/2" wye rolled up on a 45 with the 1 1/2" being the vent. You may need to run the trap toward the wall then use a long sweep 90 so that you can hide the 1 1/2" pipe that's running on a 45. Once you get in the wall you use another 45 to get the vent vertical.

thanks for the reply. I'm having a tough time imagining what you're describing. Is the trap the most upstream, or the vent?

Shower trap is most upstream.

Thanks Steve, appreciate it.

I have exactly the same question as the original post, but I see the image of the solution from Steve is no longer in this reply. Is it possible for someone to repost or post a new image of the solution? Much appreciated.
