Since the laundry area is the next on the todo list, I need to get the venting from the basement bathroom done, as it goes up through the laundry room. Here I have the vent tubing installed and I'm starting to build a shell around it. Using ABS rather than metal because I have a lot of twists and turns under the floor to connect with the vent without compromising the headroom in the basement, and ABS is much easier to work with. It's definitely overbuilt, but that's ok.
