There seems to be an interest in staying clean in an emergency situation.
That said, I have selected 3 YouTube videos for food for thought. :-D
The first one is a Yuppie outdoor shower. Not for emergency situations unless you have a generator. But heck, there is preparedness and then everyday enjoyment!
Here is a Camp Shower, 1 gallon jug plus black plastic shower stall. This is survival or camping. Lots of good info.
Solar shower style that I eventually bought, used in an emergency situation in your own shower. :)
The Sportsman’s Guide has one I’ve been looking at. It’s a shower head that runs off D batteries and is only about $18. You can hook it to a water supply, or use a container of water. Probably wouldn’t take much to convert it over to a solar powered setup.
For the first 6 months after we moved into the cabin, we used the sun shower. I would stick the little children in a galvanized wash tub in the sun. Come fall, we had rigged up our 55 gal. barrels with an RV pump to deliver water through the “on demand” or tankless, propane water heater to the shower, bathroom sink and kitchen sink.
One of my first online sales was 5 sun showers to a delightful woman who claimed confidently, “I can do anything as long as I can take a shower when I’m done.”
We have a hang up shower and you can just fill it with water that you’ve warmed via a garden hose laying out on the ground, a solar oven or ??? Use it sparingly and hang it high :-) Wet hair first, shut off. Shampoo up, rinse hair, shut off. Shampooy water should give most of your body a good washing. You can then pay attention to other parts, rinse and you’re done. If you have one of those outside potty cubicles, just hang your shower apparatus in there :-)
