The average shower uses about 2.1 gallons of water per minute. If you take a 5-minute shower, that amounts to approximately 10.5 gallons per shower. Over the course of a year, if you shower daily, you would use around 3,832.5 gallons (10.5 gallons x 365 days). To determine how much you waste would depend on what you consider waste, but if you compare it to more efficient shower habits, you might see a difference in water use.

Of course, this is only an estimate, and I can't back this up with statistics and such, but I'm sure this is somewhere close to a definite answer. :)
Shower, Shower heads can usually allow anywhere between 2.5 and 5 gallons of water a minute. Toilets can use this volume in a single flush. As most showers last longer than one minute the shower volume is considerably higher.

depending on opening and pressure possibly 2,000 GPM with no flow restrictors an open pipe, no shower head, will pump around 10 gallons per minute. a high volume shower head, about 8 gpm and highly restricted will dump less than 3 gallons per minute. try it yourself, use a garden hose and a 5 gallon bucket and shut the hose off at 30 seconds. double that for the quantity you would get at 60 seconds.
