(Fatwa: 1733/1396/B=1433)
Yes, it is lawful to charge the persons who use toilet and bathroom and it is also halal to use this money. However, instead of taking the money charged as your salary you should fix a salary for your supervision from the organization and deposit whatever amount of charge you collect in the organization. The compensation of your supervision should be fixed.
