Check out our 'Kitchen & Bathroom Solution' . This is the water supply we have in our van Rudi . With the 8 liters 'pump-tank' it works great for doing the dishes, cleaning vegetables or fruits and also for some necessary bathroom activities... it's even possible to take a little shower . We added a little cabinet to store necessary things, a mirror and a pull out sink. How do you like this solution? If anyone has some upgrade ideas , let us know .
