Antique sinks still in their original locations seem come to hard by, be it in Lviv, Prague, Vienna, or other Habsburg cities that I’ve visited. But in Vienna I did find a couple. On the other hand, I’ve come across quite a few water pumps in these cities.
Here is a remnant of courtyard sink
Nearby is an old water pump
Indoor communal sinks
This one has a similar design to some of Lviv’s antique sinks
