Renovating my basement and I have 3 doors to install. Planning to install 2 prehung doors in the first 2 locations (2x4 walls with drywall on both sides).
Not sure what to do about the 3rd. It will go in a 2x6 wall leading to a workshop that will remain unfinished (no drywall). I want the door to swing into this space. Is this a case where I need to purchase a slab door and do the framing myself?
I know you can install jamb extensions for a 2x6 wall. But if I go with the prehung, should I just fasten the casing to the unfinished studs in the workshop?
