I was looking up "scullery," and I found this fascinating The Servant’s Quarters in 19th Century Country Houses. It includes a discussion of pantries, sculleries, larders, and more. It mentions a Scottish scullery maid "who described her job as slave labor."

I remember seeing meat safes in older houses, too. When I first saw one as a child I had to ask what it was for. Back then pantries were separate rooms with shelves up the walls.
More modern houses started doing without these and larger, floor-to-ceiling kitchen cupboards then became known as pantries to the point where corner ones with bi-folding doors that you can take a whole step into are now known as walk-in pantries. Now many larger new houses are going back to having butler's pantries.
I do recall hearing people refer to pantries as larders in my childhood and this often had to do with where in the UK a particular family or their forebears had come from. If memory serves, these people also called a laundry a wash-house.
This may be just my usage but I have a tendency to call kitchen wall units i.e. overhead ones, cupboards, but underbench ones (which sit on the floor) cabinets. However this is not an absolute and I occasionally will use one for the other.

#60 - interesting link Nutrax, and one that led me to wasting a good hour following similar ones from there. Was the word 'scullery' unfamiliar to you, or at least unusual for you?
I don't think that "scullery" is a word one sees very often in the United States.
I have no idea what a "scullery" is; I think that it must be some room near the kitchen in a large house, perhaps where the silver is cleaned or the pots are washed. If I see the term "scullery maid" I think of a young woman with some kitchen-related duties, but I don't know what they would be.

My grandparents' house wasn't large, it was a medium-sized two-storied terraced house. The kitchen just had a very large and impressive cooker made of what looked like cast iron, with metal doors with locks on them for the various roasting compartments, and a kitchen table, and I think maybe the food presses were there as well. Then there was a narrow room of it, jutting out of the back of the house, where there was the sink and the dishes. I couldn't swear to it that I ever heard anyone call it the scullery. Maybe I just applied that name to it in my head as a child, but I don't think so.

This could go on for some time! After all this discussion I couldn't help but notice in Nutraxs link one of the house plans had a kitchen, scullery, pantry AND larder!! I would imagine it would be:
kitchen for cooking
scullery for washing up, probably the only one with a water supply, or water brought in from outside
pantry for dry goods
larder for fresh food, hams, cheeses etc.
I had heard the word "scullery" before, but I can't say I'e ever seen one.
An architect wroe about the Governor's Palace in Colonial Williamsburg (Virginia, US). The early 18th C. scullery was an outbuilding.
>the Scullery was used for the "sloppier" side of the kitchen department: salting and preserving, tallow and soap making, etc., relieving the kitchen of a multitude of space-taking tasks and leaving it freer for the definite purpose of preparing the food.
nutrax, And a "scullery maid" was at the absolute bottom of the servant staff, often a retarded girl who was allowed to sleep on the kitchen floor next to the stove. Here in México the Spanish word for a scullery maid – pinche – has become an often used adjective meaning "worthless". However, in Spain the word has become elevated to mean "assistant" and you will find "pinches" in nearly any trade.
