The cold water alone for 10 min shower, about 20 gallons, costs you 3c. And I think it costs another 20c for the heating of water, depends of your water heater. So, for every 10 min, it's like 13c extra.

If you are using clean towel after every shower, assuming that you can fit 20 towels in your washing machine. For the load it costs, 3c water +15c if you add hot water, +8c for detergent and softener+3c for electricity =29c, or 1.5c to clean one towel, but it depends on a size of your towel too. Plus, if you dry it in the dryer, add another 1.5c-2c.

So if you cut back on your shower time, and save 13c/day x30 =$3.90/month, and another 30c for always using your towel twice, before washing it ot if you take shower every other day. The less you use, the more you can save.
