Average time in the shower UK 2010-2014
An earlier version of the same report, noted that water used in the bathroom accounted for 68 percent of water used in households in the United Kingdom, and that showers and baths account for 34 percent of household water consumption. This indicates that reductions in shower times would actually be one of the most effective ways of reducing water use in United Kingdom households.
In 2013, the average duration of a shower in the Netherlands, for example, was 8.9 minutes.
