It doesn't mean "bathroom", but "bathroom is an euphemism to mean "toilet".
I had to flag many sentences, because they didn't accept "toilet" for "latrina". Considering that "latrina" is a kind of toilet, it should works.
And I'm still not convinced, they said "to visit toilets" in Latin. I wouldn't say it in my language, and I have no proof that Romans did.
My on line dictionary gives both latrina (1st declension f) and latrinum (2nd declension n) to mean latrine or bathroom. Is there a difference? https://latin-dictionary.net/definition/25360/latrina-latrinae https://latin-dictionary.net/search/latin/latrinum
