I’m new here so I hope my first post makes sense!
I’m remodeling my cottage bathroom. There is a floor joist right under and parallel to the wall where the shower, toilet and sink are. So the drains and vents cannot go trough the bottom plate of the wall like they usually do
To solve that issue, I plan to use the space under the sink to run them at a 45 degree angle at the bottom of the wall. Also, the kitchen sink drain merge with the main drain but I plan to vent it independently since it’s like 12’ away.
I included a shema of the rough I plan to install. I would really appreciate feedback on it : does it make sense? Is it up to code? Is it a good design?
Some of the questions I have are the following :
1) Can I wet vent the shower like I did?
2) Is a 2” main vent big enough? (I don’t want to use a 3” since it’s in a 2x4 wall, but I could if I really need to)
3) Does it makes sense to vent the kitchen sink (and maybe eventually a dish washer) independently? Can I use another 2” pipe inside an exterior wall made of 2x6?
I hope I included enough info, let me know if it’s not the case.
Thank you!!
