If I wanted to reduce my water usage, I'd just take shorter showers and alternate days when I've not yet become smelly. These cost $0 and yield immediate savings. Changing a person's behaviour, including your own, is pretty hard, its its less likely you'll actually follow through and take less showers. Some people also live in households with multiple people, so that can affect your math as well.
