The Men's Room is a British television drama mini-series that was produced by the BBC and originally aired on BBC2 from 25 September to 23 October 1991. The series, which comprises five 50-minute episodes, was adapted by Laura Lamson from Ann Oakley's 1989 novel of the same name, and stars Bill Nighy, Harriet Walter, Amanda Redman, Charlotte Cornwell and James Aubrey.
