During the hot summer months, an outdoor shower can be perfectly feasible, not only to refresh you but also to meet the basic needs of a community. Although it may seem like a luxury, its concept is completely different (and better!). A solar shower system that can be adapted for different purposes, not just for recreational use. Solar water heaters are generally a very efficient and inexpensive method of heating water.
In addition to offering a refreshing moment for hot and arid days, this shower will offer you hot water, as well as light without polluting. Integrated solar panels will provide you with all of the above at no additional cost.
A shower which may seem complicated in its construction but which in reality has no more difficulty than any of the ones you can assemble at home. In addition to being able to place it in a garden, its use can go further and be able to serve as a bathroom system in places where there is no infrastructure built or where there may have been a natural disaster, with the necessary adaptations to adapt them to each situation.
I hope this can serve as a starting point or inspiration for other projects.
