I'm working on a tiny cabin bathroom. I would not like to run a vent pipe and cut an opening in the roof. Are there any other options on the placement of vent for waste?


You will need some kind of vent or the gasses will end up inside the house. In my jurisdiction tiny homes follow very similar rules to standard construction so a minimum of 1 vent will be needed. A second vent could be achieved by using an air admittance valve if allowed in your area.

I wired a mobile home not long ago and the owner had his vent on the trailing wall below the ridge. We passed electrical and I did not notice any plumbing changes so that may be an option. I would verify with your local inspector.

  • To clarify, did the vent exit the wall and bend upward, above the roof line?

  • Below the ridge line is below the roof at the point the pipe ended outside the wall. I believe this was done for towing but it would be in a down draft area to me I asked when I first saw it and he said that was the recommended location. No windows or other openings close to it. I have not been back as it was just a T&M job I did not know the owner but was doing the job for a contractor friend I work for on the side.

  • I assumed that you meant the pipe penetrated the wall below the ridgeline, not that it terminated there.
