Me too
Thanks to this site for the bug sprayer shower idea.
I've also built my own. Seems the commercial version is too expensive for the value. I obtained the bug sprayer from Northern Tool

It's a 2.5 gallon stainless sprayer. Unfortunately it was $54. I found some a little less costly but I've had good experience with Northern Tool.
Pic 1: The sprayer had a plastic internal tube that reached from the outlet to the bottom. Someone mentioned a concern with this and heating. If you look at the Northern Tool picture you'll see that the sprayer wand is brass. I was able to pull out the plastic, cut the brass tube from the wand, insert this brass tube into the sprayer replacing the plastic, and solder into place. On top I soldered a normal brass hose fitting obtained from the local hardware store. A fitting at this point is nice as will be explained subsequently. Replacement of the plastic tube leaves a quite strong point for the fitting.
Pic 2: I often have to supply 4 showers. It is really nice to do this quickly to get out of camp in the morning. I tried to minimize heating time with the stove shown. This also obtained from Northern Tool.

This stove puts out a huge amount of heat and the burner diameter matches the bug sprayer diameter very well. Unfortunately it is something of a trick to get it to work from the small 1 LB propane bottles but that's another story. Stove is somewhat heavy but packs nicely into my rig. My only complaint is that it is quite wind sensitive. I used my water bottles as a block but I'll have to bring some light metal panels next trip. I fill sprayer with roughly 1.5 gal which gives a complete shower to a female. I can shower on much less. Heat up time is a few minutes.
If a cap is carried for the connection then the bug sprayer can be completely sealed and can be filled with water and used as additional water storage until the first shower is supplied.
Pic 3: A Paha Que shower tent purchased directly from them (best price - they had a sale)

Overall this is a really good tent and good value for the $. I got the aluminum poles. There's a setup that is about as involved as setting up a normal tent. Don't be fooled by their site video! I was impressed by this tent overall since it seems they've actually used their own product! There are a lot of subtile good things about the design. All I changed is to add external bungees around the stuff sack (they left it big so the tent is easily placed inside but once zipped it is too flooppy) and to add caribieners (SP?) at the points where their design intends that you insert the poles thru loops (a pain). You can see this in pic 4 at the point where the open zipper vents come together in the corner.
Pic 4: The shower head is made from a bent piece of stainless tubing and is clipped to a top loop with caribieners. The plastic tube is just too flexable for this operation and it is really nice to have the shower head hang above and away from the tube. Also clipping allows easy disconnection. The drill is to wet down quickly, soap and scrub with water off, then use the remaining water as a rinse. During rinse it is efficient to unclip the head and apply water directly to soapy areas. A series of several clips allow adjustment of the shower head height for various height persons. All this is about saving water and the propane it takes to heat it. I can carry only a total of 14 gal.
Pic 5: Here's a close up of the head. All constructed with local hardware store parts. Notice I've applied epoxy over most of the sprinkler holes. This spreads out a very small flow rate for better rinsing. I'm tempted to epoxy in every other hole in the perimeter shown. There's a valve located at the head which is in a convenient location to meter and shut off flow.
Pic 6: This is the lower part of the head assy, shown with the sprayer removed. It is necessary to disconnect the head assy tube from the sprayer when heating to prevent melting the plastic tube. This connection allows the head to remain hooked in the shower while only the tank is removed for refilling and heating for next shower. Picture also shows a dirt floor. The shower tent is supplied with a floor but it gets wet and muddy so I don't use it. I have a pair of cheap 'flip-flop' shoes that I pack with the shower. We just wear these when showering.
All in all, the shower is probably a little more complex than I'd like. The sprayer and head are OK but the tent is a little over the top. I like Kermit's idea for it's simplicity. Without some sort of enclosure outdoor showering just isn't pleasant if there is the slightest breeze so I have to do something. Kermit's design makes me think of those window shades that people sometimes put up inside their front car window. These have a flexible ring that can be squished. Maybe a completely cylinderical shroud terminated by one of these flexible rods at the top and then suspended from my canopy. It could all roll up for storage and could simply be shaken out into shape for use...
