Subject: Regarding the poor condition of the restrooms.
Dear Sir,
I'd like to respectfully raise your attention to the fact that our school's restroom is in terrible shape. Because of the lack of hygiene, all of the students are unable to use the restrooms.
As a result, I suggest that you take the appropriate measures as quickly as possible, and I will stay grateful to you.
I'm hoping you'll take the appropriate steps,
Sincerely yours,
