I would have to say the answer really depends on your needs. Do you need fire protection, criminal protection, or just from curious kids? Does it need to be handy in an emergency?

There are a ton of small safe options, in varying price ranges, that will fit different needs

Wander into lowes, home depot or even staples and see what they offer, most can be made to fit your needs and almost all of them could bolt to the floor.

Remember a safe not secured to the house is just a handy carrying case for a thief
