Have you tried condensed water?

Comes in a can and you just need to add four cans of H2O and you have regular water.

The sugar can be an issue if you are on a diet.

In which case go with the evaporated water. Same process but without the sugar.

I don’t do sugar at all, so I’d have to go with the H2O evap.
