After remodeling my basement I noticed that the hinge side of a new bathroom doorway (built by me) is almost 3/4" out of alignment at the bottom. I must have kicked it or something before attaching it to the slab. Unfortunately I didn't get around to installing the door and noticing the problem until everything was sheetrocked and painted. Moving either side of the door frame would be a huge pain because of attached walls and very solid construction. Building out the frame at the bottom is also possible, but with that amount of warp I think it will look wonky. The door will spring shut but only when slammed forcefully. I'm wondering about warping the door to match the doorway. Is this possible? It's an old reclaimed frame-and-panel door which I'm sure is at least 80 years old. I have no idea if a door this old can be warped, how to do it properly, and will it hold the warp?
