All these diagrams and suggestions for an "awesome shower" seem like overkill and not very permies oriented. When I want an awesome shower, especially after a good work day outside, I fill my shower bag early in the day, lay it out on a dark surface and let it heat up. Many times it will be so hot that I have to add a little cold water to temper it. I then hang up the shower bag and let the water run. This is an "awesome shower". Air drying in a cool breeze reinvigorates my soul and prepares me for a relaxing evening.
