If you use body wash, try switching to bar soap. It comes in much less packaging, and the cardboard it is wrapped in is much more easily recycled than a plastic bottle.
Do the same for your hand soap. Get a soap dish and switch to a bar. It's better for the environment and cheaper too. While you're at it, make sure you aren't using antibacterial soap. We're killing off good bacteria and creating super bad antibiotic/antibacterial resistant bacteria.
