At first glance, you might mistake it for a splash of paint or a trick of the light, but that light pink stain in your sink or shower is a living organism.
Pink mold is a misleading term; it’s actually a type of bacteria known as Serratia marcescens. This bacteria is found naturally in soil, food and animals. It thrives in moist environments and doesn’t need much to survive.
Aside from your sink, this pink bacteria can make a home on various surfaces, especially in bathrooms. You might find pink mold on shower curtains, shower walls and even in the 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.
