Solid wood can look excellent and take stain beautifully, yet it absorbs moisture if the finish is not maintained. Once that happens, expansion and contraction can make the door rub, swell, or stop latching cleanly.

It handles moisture far better than wood, does not rot, and stays dimensionally stable through seasonal changes. That stability matters because a door that does not move much is easier to seal, which helps with comfort and energy bills.

The main concern is not swelling, it is corrosion. If the protective coating gets scratched or the door is poorly maintained, rust can start at edges, seams, or hardware cutouts.
