It definitely looks gross, and it could be a cause for major problems. The majority of shower mold is just awful looking. However, it might pose a risk for people with respiratory issues and allergic reactions. Unknowingly, mold spores can become airborne and, when inhaled, can be hazardous to someone's health. Truth to be said that shower mold probably will not kill you, but direct exposure can trigger you to have a cough, runny nose, and mild to moderate headaches. Thus, it is best to eliminate these molds in your living space.
