The wife is thinking of setting up a childminding business in our converted garage at the end of the garden, miles from the water and sewage mains. The law says we need to have a sink and toilet on hand for the children to use, but apparently these don't need to be mains-connected. I'm looking for suggestions on how we can achieve this. I think the toilet requirement can be met by something like this:

...but I'm less sure about the basin part of it. From a user experience point of view, all we need is a basic cold water tap and a basin. Can we simply put a water tank up near the ceiling and have a tube running down to the tap, and then have the basin drain into a water-butt? We would fill the tank using the garden hose each morning, and empty the water butt each evening into a basin in the house.
Or do ready-made solutions exist for this?
