Not that many years ago I worked at a house that had a bomb shelter. The entry was just a flip up door in the floor of the pantry much like any other access door to the underside of a house. It led to a set of stairs that were somewhere between a ladder and stairs. At the bottom it was narrow with stepped up sides like a bunk bed or counter, all concrete. There was minimal lighting and no secondary means of support for the ventilation, lights, etc. The vents were somewhat camouflaged but not much more than a dryer or WH vent.

What got me was the echo down there. So much echo that it was uncomfortable to talk. I sure with provisions and occupants, that would subside, but the whole thing was ridiculous.

Nice constant cool temps though. If it wasn't such a PITA to access it would have made a killer wine cellar.
