I think it was Gunsite that used to say, "If you ever find yourself more than 3 feet from a gun, we haven't done our job."
They certainly wouldn't feel that they've done their job with me, but I keep that in mind in my house. I have guns stashed so that no matter where I am, I can retreat to a location with a firearm.
For example:
1) Shotgun in my bedroom behind the headboard on my wife's side. You can't see it. Seven rounds total. Cruiser Ready.
2) Full-sized, high-capacity handgun in my bedroom between the mattress and box spring with two extra magazines. 48 rounds total. Condition 1.
3) 3oz Pepper Spray in coat closet.
4) .25 caliber pea shooter stashed under the closed lit of our coffee table in the living room.
5) .44 Magnum revolver in hidden compartment in the wall. Ever see those frames that are actually hinged storage compartments? It's something like that. This is close to the back yard where beasties roam.
6) 9mm, 10 rounds handgun under loading bench. I always have this terrible fear that someone will sneak up behind me while I have a disassembled .308 in my hands. I've even got headlines made up for when the police find my body.
I know. No bathroom gun? Don't need one. Ever see a naked guy run out of the bathroom with a straight razor? Terrifying.
Don't forget the knives.
The only thing I can get to easier than a weapon is a flashlight: two in the kitchen, two in the hall, one in the livingroom, four, no five, wait there's six in the bedroom if you count the LED light in the shark's head, one in the basement, one if by land, two if by sea and I with a 10 million candlepower spotlight shall be...
