moving Vanity drain from side wall to back wall

[Stephanmmjohn]

I am renovating a bathroom and the drain is coming from the side. This was done because the vent stack is on that side wall. The wall directly behind the vanity would be an outer wall. Refer to the images attached for clearer view.

I am planning to put an Ikea Godmorgan vanity with drawers. I would like to move the plumbing to the back so there is no interference with the drawer. Since its an outer wall, I prefer not to go behind the wall, instead go down through the subfloor.

1. Would the proposed new drain run be viable? (would it be vented, up to code, etc.)
