My friends father had a garden hose on a coil right at the top of the basement stairs that would reach the whole house, I always thought that was a good idea.
When I had a 50x60 commercial shop, the fire marshal required a fire extinguisher within 75 feet, so for that building one was enough.
I have fire extinguishers all over the place, most I got for free from a fire extinguisher service company near me, they are past their date of service, and can't be put back in commercial buildings but every one I ever tried worked just fine.
I've trained my kids on how to use them, made a fire outside and let them discharge some of the old extinguishers, just so they know what to expect if they ever need to do it for real.
Got some of the water filled ones as well, I keep one of those near my my fireplace.
