How can I secure a fire safe in an apartment? Answered

I have a small fire-rated safe that I would like to bolt down in my upstairs apartment.  I can't drill holes through the sides of it and put screws into the wall studs.  There's a single heavy bolt hole in the safe's bottom.  Does anyone have any (real) suggestions on how I might secure it to the floor?  Is there likely to be space between my floor and the ceiling below me that I can slip a brace into?

EDIT: I lifted up the edge of the carpet, and it looks like the floor under the carpet padding is concrete.

If you can't use a single screw because it would a too big hole in the floor:
Make a metal plate with several small holes for normal wood screws, like one in every corner.
Drill and tap a hole into the plate for the safe mount.
Screw plate onto floor, best in a corner, put safe onto it and screw it down onto the plate.

If in doubt use duct tape or a bigger hammer ;)

I'm not really worried about the diameter of the hole, as I can patch it back up with concrete when I move out. If I do put a bolt into concrete, though, it might be a pain to get it back out later on.

Get a short Dynabolt ;)
They sit flush on the surface and once the bolt is removed there is only a small hole.
Best option for concrete.

That's an option. I'd still have to drill. Am I likely to hit anything buried in the concrete?

If you use the short Dynabolts I highly doubt it.
Especially not in a corner.
Rule of thumb: Check where your lightswitch is located and where your lamp is.
In 99.9% of cases the layout won't change from one story to the next and the only thing you might be able to hit in the floor is the cable for the light in the flat under you.
So if you are outside a straight line between your light and the switch there should be nothing except some reinforcement in the floor.

I lifted up the edge of the carpet, and the floor is concrete. I don't know how thick the slab is, but I assume it's solid all the way through to the first story's ceiling. Would it be possible to drill part way down and put in a bolt? That might be tricky since I don't know the thickness. It would be embarrassing to drill through the ceiling below and have to explain to my landlord that I was drill holes through my floor.

Why not use a big coach screw into a floor beam ?

How about a steel plate with screw welded in the middle, epoxy to the floor, and drop the safe over the screw ?

Applied properly, I should think so. Make the surface area of the plate nice and big.

Try inside a closet or wardrobe. that way you can secure it to a shelf or the walls. Just as in a hotel.

I thought about making a little cabinet for it, bolting it to the bottom of the cabinet and then bolting the cabinet to the wall. I can't put a screw through the side of the safe.

You can attach metal rods or 'U" channels secured inside the safe using hardened carriage bolts. ... These are placed so that there is no way to remove the safe through the closet door with the extra metal by rotating or shifting the assembly unless you know the combination to remove the nuts locked inside.
