I demo'd my bathroom yesterday and under the vanity the drains are above the subfloor for over a foot. Of course I bought a vanity already that has the feet that you can see under so this is a problem for me.
It looks like they did not go through the baseplate of the wall because the drains feed into the main sewer line that is in the next floor joist bay. Can I drill through the top 3rd of the floor joist (2x10) here and rerun the pipes under the subfloor?
