One would do well to remember that water is most places a fairly cheap commodity. One would do even better remembering that showers represent but one type of water use. Taken together, a two-thirds reduction of water used in showering might not result in any great savings of cash. Plus, the possible inconvenience to the residents might lead to a small-scale Hejira to some better-watered residential oasis. Thus, in the end, money saved might sadly amount to little more than the proverbial drop in the bucket.
