I have 2 solar showers inmy camper. Not the fancy black plastic bucket with pressure. But also not $80..
At any camping store you can get them for about $10. Heavy black plastic 5 gallon bags with hose and shower head. Hang em in a tree and they work great. Mine have lasted at least 5 years already
BTW mine didn't come with a bikini clad young lady:think but I don't think my wife would let me scrub her back anyways
I think that SpokerAce picked up ours at Bass Pro Shops $15.00. Good thing that they have a temperature strip built into the bag. We put them on the tail gate of the truck and went riding. About an hour later they were up to 110 degrees!
Five of us were able to take a "quickie" shower (Hair and body) with just one of them (5 gallons). They worked very well.
