Shower not bath thing, by the way; this assumes that you are the sort of person who takes an ultraquick shower. Your average bath uses something like 80l of water. The argument used to be that a quick shower uses only 20-30l or so - you get solar bag-showers, heated by the sun, that are only 5l - but given the way modern power showers are, and if you take a long time in the shower too, there's a better chance of using the same amount of water in a shower these days as you would in bath. Apart from the water usage itself, there's also the heating method to consider; if it's been heated in a nice efficient gas boiler and kept in a lagged cylinder or if it's been heated on the spot in an electric flow heater running at at least 7kW, or the equivalent of at least three modern kettles, though this depends on the type of shower.
Umm, and the campaign thing was about turning off the water when brushing your *teeth*, not hands? Because a surprising number of people stick the tap on to wet the toothbrush and then leave it on while they aren't using the water at all, just doing the main brushing bit.
