It doesn't waste water, that water isn't destroyed it just goes down the drain and eventually ends up back in the water cycle.
Bottled water, the water in the bottle isn't the problem, it's the bottles, and the shipping for the bottles and the shipping of the water etc.

I would suspect zero, I don't think a fridge's insulation changes depending on what's in it, and how hard a fridge has to work to maintain a temperature would be related to the insulation... cooling the water would take more energy, but as you say bottled water is also cooled in the store, so that's a wash.
You are right though that you have to take everything into consideration.. but when some bottled water is shipped half way around the world (Fiji brand) and the energy and resource costs of manufacturing and transporting and disposing of billions of bottles there's no possible way the energy costs for that aren't orders of magnitude more than turning on a tap or cooling your bottle of water.
