I did Tom - a 'toilet saloon' was the same thing as a 'toilet club' - run by a barber, patrons who paid a regular subscription got reduced rates in return. There were an inordinate amount of them around in the late 1800s to around 1930 or so. There is a record of a letter sent to a newspaper by a Mr Ludwig of Beaufort Toilet Club in 1888 complaining that he was not to be confused with another Mr Ludwig who was a suspect in the 'Jack the Ripper' murders.

I find it a bit of fascinating history, now lost together with its not very 'pc' sounding name!
