There is one restroom in Macrodata Refinement. Toilets are separated by green stalls. A counter with built-in sinks is opposite the stalls, and a large mirror hangs above.

The restroom can be considered unisex. There is no separate men's and women's restroom.

The tasks of cleaning and replenishing supplies in the restroom is the Macrodata Refinement Department Chief's responsibility. These chores, among others, are included on the morning checklist that the chief completes before the start of the workday.
