Because of how the joists runs in my bathroom, and because there is a
plumbing vent pipe in the same joist bay by the sill plate, I had no
choice but to drill the 4" hole in that spot. I could not go up,down
or side to side, this was it.
As I posted before, if I can find those mounting blocks at Lowes, HD
or some other building supply store, it loos like the best option.

or cut some yourself from one-bys, prime, caulk, paint.
