Here are the actual and ONLY risks for HIV transmission. HIV is transmitted by unprotected vaginal or anal intercourse (penis without condom IN - with penetration- a vagina or anus) or sharing IV needles to inject drugs. Air inactivates the virus. You don't get HIV from anything you touch or touches you outside of that. So, no to the floor. The toilet. The faucet. The water she used to wash. Her hands. No risk
Also the bathroom was at the message parlour
