Aquire an old steel bath tub from the local land fill. Prop it up on bricks outside and build a small fire underneath it. Fill it full of snow (presuming you're in the mountains) and jump in when its at a bath able temp.
Like to shower instead? Grab one of those things hikeswithdogs suggested, or go the ghetto version and find a couple of 20L paint pales, knock about 12-20 2mm holes within a 5inch area in the bottom of one of them, hang the pale in a tree. Get all your wash cloth and showering stuff ready by the tree, heat approx 10L of water and tip it into the pale - then get under it quick...use a construction pallet as a shower mat and maybe (depending on how far out in the wilderness) put up some form of shade cloth (also aquireable from a land fill or jumble seller) around it so that people can't see you showering.
Other places to get a cheap shower - YMCA, Public Baths etc etc
