In my basement I am renovating one of my rooms that has a 30" door. There is no jamb, the hinges are screwed directly into the 2X3 framing, and the walls were 70's style wood paneling that were nailed up to the edge of the door frame. The door worked well with no problems, but now I am replacing the walls in this room with sheetrock. My options are:
1) remove old door, and put in new 28" door with jambs ( since framing is already there), but I'm concerned with making the opening 2 inches smaller, poses a problem when trying to get furniture in this room. Also because of space limitations, I cannot extend opening frame to 32" to accomodate a 30" prehung door.
Leave door as is , and sheetrock up to edge of the door using a J-bead or corner bead to finish off, paint inside frame, and put molding on afterwords.
