Outdoor shower

For several years I have had a simple outdoor shower..... a black 30 gallon garbage can on an 8 foot tower.  As winter sets in, I am looking to go up a step or two in sophistication.  Maybe something with a 4x8 panel and black piping?  Does anyone have any design plans?

To be clear, I do have indoor plumbing.  This shower is for a fast wash off outside if I get too cruddy.

Years ago when I lived in an offgrid cabin in the backwoods of Georgia I made a shower with a 50 foot coil of black plastic irrigation hose, laid on the cabin roof under a piece of clear plastic.  A tank on a hill provided pressure to this, and to a cold water hose that ran directly to the shower head, where a simple hose "Y" enabled me to mix hot and cold as needed.  The shower itself was inside a greenhouse/shadehouse....covered with plastic in the winter and attached to the back door of the cabin which usually stood open, enabling heat from the woodstove to heat the greenhouse at night and on cloudy days.  The plastic was taken down and replaced with shade cloth for summer.  This basically enabled hot showers in the afternoon in all but the most hard freezing or cold cloudy weather....in other words all spring-summer-fall and probably half the time in the winter.  In hard freezes I would shut this all off and go to plan B...a pot of water on the wood stove!

This solution is not exactly upscale but it works well for me and the dog. I have an indoor (laundry room) utility sink near the doorway leading outside to a private garden. On that utility sink I have installed 3 features: 1) a threaded utility faucet, 2) a threaded hose bib with ball-valve on-off attached to the base of the utility tub, and 3) a simple hose caddy. A dedicated garden hose attaches to the utility faucet to enable warm water through the hose and outside into the garden area. Attaching a pistol-style spray sprinkler to the hose gives me a nice hand-held shower with on-off control. Filling the tub with a biodegradable soap solution and warm water then attaching the hose to the tub itself creates a pleasant and safe gravity fed wash experience for the dog. Keeping a dedicated hose inside on the caddy keeps this garden hose clean, warm and pliable for showering outside even in winter. Very simple but perfect for warm "a fast wash off."
