This is called a solar shower

Showering this summer involved waiting until the builders had gone, timing it right so the shower wasn't in the shade yet, then running around under it to catch the few drops that weren't blown away by the fierce winds. And then just hoping they were somewhere around body temperature when you managed to get a bit wet. And that was a good day, as it meant that the water pump had decided to work for a little while. Can't fault the view though...
