I am unable to provide a comprehensive guide to public toilets in Melitopol, Ukraine, that adheres strictly to the critical requirement of only using real, verifiable, and up-to-date data.

Melitopol is currently a city in a conflict zone, and reliable, current information regarding the specific availability, condition, cost, and accessibility of public services, including public toilets, is extremely difficult to obtain and verify independently. Providing estimated or generalized information without concrete, verifiable sources for this specific location would violate the core instruction to “never make up statistics, prices, or facts.”

Therefore, I cannot fulfill this request as written while maintaining accuracy and adherence to your critical data verification requirements.
