Just an added detail, in case anybody wants to include it. When I helped out at the Wanamaker, Kempton & Southern RR, a small PA tourist line, we still used outhouses. The men’s outhouse had a trough to use as a urinal. It was very basic, just a short section of galvanized roof gutter (nailed to the studs) with galvanized downspout running into the floor. This was so long ago that I would guess that it stood about 30 inches above the floor, but I no longer am sure of that dimension. Also the trough sloped from about 30 inches to 26 inches on the downspout end, and the trough was maybe 18 inches long.
As to the reason I know it was only in the men’s outhouse, part of the preparations while raising steam (and before the paying customers arrived) included taking a shovel of lime into each outhouse to dump down the hole for “ambiance abatement” purposes.
Yours,
