The word *scullery* refers to a room where certain kitchen-related tasks (including cleaning and dishwashing, but not the actual cooking) is carried out. You might find this a useful alternative but you'll need to adapt your usage to make it fit.

I've not seen "scullery" used as a noun indicating an action. Note that "sculling" means something quite different (related to sailing).
