A portable hand wash station includes a base that can set upon the ground. A fresh water tank and greywater tank are disposed atop the base. A tank cover is disposed atop the tanks. The sink member is pivotally mounted to the tank cover with a hinge. The sink member defines two sink basins that oppose one another. Each sink basin can be shaped and sized to allow the user to wash their forearms. A backsplash member can be secured to the sink member between the individual sink basins. The fresh water tank access can be secured by locking the sink member to the tank cover. A plurality of rods secure the tanks in place between the base and tank cover without protruding through a sidewall of the tanks.
