Clever Outdoor Shower Idea

I have a lust for outdoor showers. This summer we made a "ghetto" outdoor shower in our backyard from a garden stake, a water hose and a nozzle. We even covered it with a shower curtain, but I still felt too weird to really shower out there.

So I really want a nice, outdoor shower at a beach house. And a heated one would be even better! But I don't know if it's in the budget to run the hot water out of the house..we shall see. There are a lot more pressing things to take care of first.

So I thought this idea was pretty clever. This person has rigged a tankless gas water heater through their outdoor shower. It looks cute and seems very economical.
