During the night our hot water heater quit working. This did not change the need for my morning shower, however.
It really isn't that bad. You get completely wet and turn off the water. Wash your hair thouroughly. Soap the rest of you well. Turn on the shower and rinse your hair very well. By that time your head, face and arms are used to the cold so rinse them too. Now your middle front is pretty much used to the liquid ice, so go ahead an rinse that and your legs. Hardest part for me was my back. That cold water on my sore neck and shoulders was a bit of a concern, but turned out to be a piece of cake.
All in all, hot water is really nice to have, but not a necessity.
