I built a $65 roomy inside hot shower that should work if you can clear out (even temporally) 32" dia of floorspace. Whole setup fits in a regular grocery bag and weighs less than 7 lbs. I have 2003 hi-roof Sprinter, but this should work in low roof vans with addition of a stool. No leaks, floor stays dry.
Components:
32" dia folding dogbath with 8" walls
108" × 72" polyester shower liner
Collapsible bucket
12v Cig. Lighter shower pump
Setup takes under 10 min:
Heat 3qt water to near boiling on stove
Attach curtain to clips on ceiling
Mix hot & cold in bucket till warm.
Pump in bucket, clip head to ceiling.
Navy shower, but 1.5 gal more than enough for soap-up and long rinse. If sunny, curtain and pan dry in minutes. Have many absolutely no leak uses!
Really interested for a low roof van owner to try out. Will need to trim liner and probably use stool in shower pan.
