Do you often see the sink in front of the toilet? It's not a coincidence or a fad for the placement of the sink. For health reasons, the sink is placed in front of the toilet.
The toilet is a place where there are many microorganisms, because this place is used to urinate and defecate. The place where the most microorganisms are found is on the doorknob. Doorknobs are cleaned the least often, whereas everyone going in and out of the toilet is holding the doorknob.
It is not impossible that microorganisms easily stick to our hands. Therefore, every time we leave the toilet, it is highly recommended that we wash our hands in the sink. Wash your hands with soap and ensure that all parts of your hands are clean, including the wrists and between the fingers.
