What does "facilities" mean here? Does it have a different meaning from with the singular form "facility"?

"Facilities" actually means "washroom," "bathroom," or "toilet" here! It's usually used with one of these two words before it. When used with "facilities," it has the effect of becoming more formal in tone. Ex: Where are your washroom facilities? Ex: The bathroom facilities are on the left.
