Setting up a portable camping bathroom is fairly straightforward. First, choose a level, private location for the unit. Next, assemble the unit according to the manufacturer's instructions, which typically involves attaching the waste tank and filling the fresh water tank. If the unit includes a shower, set up the shower enclosure and connect it to the water supply. Once the unit is assembled, it's ready to use. To maintain cleanliness and hygiene, be sure to regularly empty the waste tank and clean the unit as needed.
