Living the van life? Taking a shower can involve a gym membership, a product like RinseKit, or something as small and simple as the aptly named Simple Shower. Fill a plastic bottle with warm water — a one or two litre bottle will do, though it’ll fit plenty of others including larger ones and rollable Platypus bottles — and then screw a Simple Shower onto it. Flipping it upside down nets you a low flow shower with a 1.8 gallon per minute flow rate, meaning a 2 litre bottle would get you about 36 seconds of water. Granted it’s not as powerful as the shower in your home nor does it give you the leisure of time, but in a pinch and while camping or backpacking it’ll get the job done.
