Back when I was young and poor as fuck I had a rental which was a guest house in Burbank CA which had a 1/2 bath but it was fully fenced in and had a garage.
Perfect for me with dogs & gf (now wife) and a pro musician. Made the garage into an amazing studio for rehearsal or recording, complete with pro tools, piano, side by side drum sets, and stolen cable.
But that pesky half bath...
So I ran hoses, like literal actual garden hoses off the hot and cold from the outdoor washer dryer, to a plastic/pvc "poolside shower" and created an outdoor shower.
Great about 10 months of the year, but even LA gets nippy OUTSIDE in december/January. It would get to 40-50 degrees (F) some days and that little 20 foot sprint inside would freeze your tits off, so I kept a bottle of Dewars. Never liked Dewars. But that BURN proved to be a perfect counter measure to the cold air when the hot water went off. I'd take a big ol swig of dewars right before I shut the water and that warmth would stay with me on my walk around the corner back into the guest house.
