That looks like a bathroom from a building around 1880-1910 that I have seen several times in GrĆ¼nderzeit buildings in Germany
The Speisekammer 2/3 of the height under the window and entered from the kitchen is missing. But despite that it looks like the average Berlin Bathroom.
From my Dutch understanding of German Speisekammer is āfood roomā, so whatās that doing in a bathroom?
Or am I missing something?
Kitchen and Bathroom were usually next to each other. In the kitchen is a small door to a room with a small window. This room has about 2/3 of the floor height. Is was used as a kind of refrigerator (by opening the window). In the bathroom is only a channel above the Speisekammer with a small window, which is only to get the perfume out.
