Hot to cold or cold to hot?

And what type of shower valve? A single handle or 2 faucets?

Bad point-of-use water heater?

While it could be quite a few things...

I am going to guess that you have a temp and or pressure shower valve that is not working right...that would be where I would start looking for a problem...unless you are having the problem else where in the home...
