There are several ways to stay clean in the van.

In-vehicle showers can be both power-, space- and water-intensive, putting them out of reach for most van dwellers. Class C and larger vehicles have the space and water tank capacity to make regular showers a reality.

Folks in vans do have some shower options, although expectations may need to be adjusted.

• Class B vans may have internal or outdoor showers.
• A sink sprayer may be long enough to reach out a window or door.
• A solar shower is warmed in the sun then hung up so the water is dispensed by gravity.
• Submersible pump showers will pull water out of a bucket or other container and out a showerhead.
• Tankless water heaters run on propane and can dispense more than a 1gpm of hot water.

The easiest way to get long, hot showers is to have a gym membership. The most common amoung 'dwellers is the Planet Fitness “black card” membership, since it allows use of any PF nationwide.

A sink bath is very simple. Put some water in a sink or large-ish container¹⁾ and use it to wet and rise a washrag, scrubber, or sponge. Wash a small area, wet and wring the rag, repeat.

Soap is not required for this process. If you do you soap, consider having a seperate bowl for rinse water.

The washwater can be used to rinse pee bottles, etc.
