Hi Ethan, and thanks once again for your help here. While I'm happy to be starting with a blank slate, there are also several sticky issues with this room. Below is a picture of my back wall. As you can see, it is hard to maximize trapping there while maintaining symmetry. Looking at the picture, I have 18 inches from the left wall to the left side of the closet door. Because of that, I can make two 18" wide floor-to ceiling traps. The thickest I can go here is 4" because of the door on the wall in the opposite corner.
