I am planning to rent a campervan during a 1-month trip to New Zealand (South Island) which is self-contained, however, does not come with a shower. I wonder whether it is ok to use a solar shower while camping at Department of Conservation or other camp grounds? I strictly do not intend to use any shampoo or other chemicals while showering (I plan on taking proper showers every few days when staying at private camp sites with proper shower facilities).
I am asking because I intend to get deep into the back country for fly fishing where there are not always camp facilities with showers available.
