At first glance, you might mistake it for a splash of color or a flash of light, but that bright pink stain in your sink or shower is a living organism.
Pink mold is a misleading term; It is actually a type of bacteria known as Serratia marcescens. This bacterium occurs naturally in soil, food and animals. It thrives in moist environments and doesn't need much to survive.
Aside from your sink, these pink bacteria can colonize on various surfaces, especially bathrooms. You can find pink mold on shower curtains, shower walls, and even in soap scum that builds up over time.
It loves to lurk in damp areas, so your shower is like a five-star hotel for these uninvited guests.
