From what I found on the Internet, a brief shower is more water efficient than a bath. I was wondering if there is any research about water use with more than one person using a shower? My gut feeling is that two people showering uses around 150% of a one person shower.

Notoriety is established with the the following catch phrase Have a shower with your fella, Stella which was part of Australian government TV campaign during water restrictions a few years back. (Cited here and here.) The implication is that two-person showering saves water.

This was a question in the Children's edition of Trivial Pursuit. I found this memorable and irritating because the answer is subjective. Some people shower longer than others. – Brian M. Hunt Jan 23 '12 at 20:15

There can be other benefits to sharing a shower than just using less water. Just saying :-) – Zano Jan 24 '12 at 12:06
gogreenzine.com/shower-timer is an environmental website claiming that sharing a shower saves water. – Andrew Grimm Sep 3 '12 at 13:30

I have heard the phrase "Save water: shower with a friend." batted around from time to time, but it is always clear that the speaker is thinking along the same lines as @Zano... – dmckee Sep 6 '12 at 14:58
