Navy showers are short, methodical showers intended to use minimal water. 1-2 gallons of water per shower are possible.

The general process is:

1. wet the surface to be washed
2. lather/scrub as needed
3. rinse

Practice this procedure in your home shower before hitting the road.

These typically rely on the Navy shower method due to the absence of cheap power and water off-grid.

• $thousands in panel and/or battery - heating water with electricity you make off-grid. Heating elements are typically over 1000w. Of course, if the 110vac is shore power (extension cord to a socket somewhere) then you have won the vandweller lottery and copious power is no problem.
• $150 - on-demand propane water heater.
• $15 - use a solar shower bag to heat the water for free then hang it inside for the shower. This does require a bit of planning to set the bag out ahead of time.
