Photograph by Lucky Nugraha, My Shot - Brightly colored bathing boxes line the sand at Brighton Beach. Victorian morality created the huts, situated close to the shoreline so women could slip into their bathing costumes and race to the water discretely.
As noted in this article ("Victorian Morality," Wikipedia), the Victorian Era (1837-1901) was full of progress and also contradictions. The important matter was to maintain outward appearances. This is exactly what most (all?) of the characters in the play are talented at: making others feel somewhat at ease with what is said, but underneath it all plotting for selfish gain.
