That depends on both how quickly water flows out of the shower head (gallons per minute) and how hot the water is (ratio of cold water to hot water).

I believe most shower heads have the same rate of flow. 2.5gpm x 5 min = 12.5 Gallons I suggest checking your own showerhead to see if the gpm is listed. You can always check with its accuracy with a five gallon bucket. Let your shower run for five minutes and count how many times you can fill the bucket.
