The Common Bacterias Found in Grout Lines of Bathrooms

 In Home Improvement, How-To's, Tile & Grout

It is not surprising that bathrooms are one of the dirtiest places in a home. Even after a good cleaning, a bathroom has hidden bacteria all over the place! One of the most neglected areas in a bathroom, that also stores the most bacteria, is the tile grout.

Grout cleaning is back-breaking labor that most people admit to only doing once a year. Tile and grout located in the bathrooms are breeding grounds for bacteria due to the warm and moist environment. Homeowners should be wary of this and hire a professional tile cleaning service to protect themselves against harmful and unwanted germs.

Below we have compiled a list of some of the most common types of bacteria found in tile grout. It is important to note that all of these illnesses can be treated with a round of antibiotics but it is best to avoid contracting them.



Salmonella is spread through contaminated food and water. It is also one of the most common bacterias found bathrooms. Salmonella can be hard to contract for healthy adults but individuals with a weakened immune system and children run a higher risk of developing adverse symptoms. These symptoms include:

  • Diarrhea
  • Fever
  • Vomiting
  • Chills
  • Abdominal pain



Commonly known as ‘strep,’ this bacteria is one of the most prevalent of our time. Step is an airborne bacteria that most often manifest in the body and causes a sore throat. Strep throat is the most common manifestation of strep but this vicious bacteria can also cause more severe illnesses like:

  • Scarlet Fever
