The Cottonwood Cove restrooms are two buildings in Cottonwood Cove that are located close to the docks.
The bathrooms are just that, bathrooms. Stalls line the north walls of the lavatories and sinks are either to the left or right of the door, and there are urinals in the men's bathroom.
Inside the ladies restroom there is a Sunset Sarsaparilla star bottle cap on a shelf
The Cottonwood Cove restrooms appear only in Fallout: New Vegas.
