If the only kind of camping you do is the kind where you drive up to a campsite and unload your posessions like a barbeque, tables and lawn chairs, tents, and many comforts of home, you will probably want a camp shower that is easy to use, reliable, and provides as much hot water as you need. Unless you’re into harnessing the energy of the sun for use in heating, like in solar camp showers, and willing to forego a hot shower if it’s an overcast day (which I highly doubt), you will want an outdoor camping shower that delivers as much hot water as you want, when you want it, and right when you want it. You will want a camp shower that is powered by a non-solar energy source, meaning here either propane or another fuel.
The best choice for people like yourself, who don’t need to worry about carrying weight on their backs like backpackers do, is probably something like the Zodi Propane Shower and Hot Water Heater. This works using propane and batteries to supply continuous hot water in quanitity, meaning your whole family can get a nice hot shower. You are thus not at the mercy of whether the sun is showing itself or not on any particular day.
For family camping trips where privacy might be an issue, car campers will also want to get a camping shower enclosure such as a camping shower tent. This way, each person can get some time to themselves and shower without worrying about someone stumbling across them in the nude.
Another option for car campers is a camp shower that hooks up to your car. The water in these showers is heated up using the heat given off by your car’s cooling system. The downside to this is that your car has to run in order for the water to be heated up, so this is most ideal for trips where you know you will be driving most of the day and then stopping off to camp somewhere for the night.
