Step # 1: Make sure you have the essential pieces for your shower. The 3 items in the photo, plus the usual cleaning products should all be nearby.
Step #5: Check to make sure the water heater is unplugged.
Step #6: Now you're almost ready to take your nice hot shower. Locate the dipper, in this case a marvelous, ladylike fuschia pink plastic scoop. <Please note that anything that scoops can be used if you can't locate this exact item. Things I've used: coconut husk, bottom half of plastic liter bottle...my friend Susie tried to use a live turtle, but that's another story. :)> It is imperative that you check the water temperature before dumping water on your head. Start by touching the water with your finger. Then mix it with the scooper, assuring that the heat has been thoroughly distributed. Add cold tap water as needed to get your preferred temperature.
Step #7 You are now ready for the actual shower. Squatting works best, since the water is limited. Soap up. Rinse. Wash hair. Rinse. Condition. Rinse. Rinse. Rinse. Rinse. Please note that at the bottom of the bucket you might find chunks of what looks like clay. It's gunk from the water heater. It's best to not use that for rinsing. Cause you just end up full of chunkies...which is I think what might have started this process in the first place. So, as tempting as that warm water looks, don't be drawn in...walk away. Find your towel. You've just accomplished your goal. Congratulations!
At this point I think you should know that tonight, after almost 5 years of bucket showers, for the first time I stuck my hand in the bucket to test the water while the heater was still plugged into the wall (220volts). It hurt. I didn't like it. But I did laugh at myself. And I thought maybe some of you would laugh at me too. Which led me to this post. :)
