In the United States, public bathrooms are commonly referred to as "restrooms" — a term that doesn't imply a place for resting or sleeping. Across the nation, public restrooms are widely available and generally well-maintained. Should you encounter poor sanitation conditions, you can always report them to the management.

Restrooms in restaurants, airports, and shopping malls are freely accessible to all, regardless of whether you're a customer or guest, so there's no need to feel hesitant about using them. However, it's worth noting that many gas station restrooms remain locked for security reasons; in such cases, simply ask the attendant for the key and remember to return it after use.

Maintaining restroom cleanliness is considered basic courtesy. While staff are legally required to wash their hands, all users should practice good hygiene habits. Regarding security, while many stores employ surveillance cameras to prevent theft, restrooms remain camera-free zones due to privacy concerns. You'll typically find signage at entrances reminding patrons not to bring merchandise inside — those needing to try on clothing should use designated fitting rooms.

Restroom signage varies by establishment. Some use simple gender symbols, while others display "Men" or "Women" labels. Accessible facilities feature wheelchair icons, and family restrooms accommodate all genders and children.

When needing directions, you can ask "Where's the restroom?" or specify "men's room"/"ladies' room." Most facilities include baby-changing stations for families with infants. Standard amenities include toilet paper, with many locations providing paper towels or hand dryers for convenience after washing.
