The last place I put a fire extinguisher. If you think about it, we will be most likely taken by surprise by a fire in our home while we are sleeping. Cheap insurance to be able to get out of a burning home at night or be able to get to a child's room. Let the experts put the fire out, this just allows you to leave that much easier.
During a recent bathroom re-model I added a garden hose outlet with a new globe valve and a 25' nylon/cloth hose under the bathroom sink. The hose is folded accordian style, held together with heavey duty rubber bands, just enough to keep it out of the way. A quick 1/4 turn of the valve and the hose uncoils itself. Again, insurance to be able to get out of the house.
