Why is my shower grout turning pink?

The pink discoloration in shower grout is typically due to a type of bacteria called Serratia marcescens. This bacteria is naturally present in warm, moist environments like showers and can turn pink when it reproduces. While it's usually harmless, it can be unsightly and may indicate that your shower is not being cleaned thoroughly enough.

Other causes of pink grout

  • Hard water: High levels of iron in hard water can cause rust stains, which may appear pink or reddish.
  • Mold and mildew: In some cases, pink or reddish stains can be caused by mold or mildew growth, which thrives in damp environments.
  • Cleaning products: Certain cleaning products, especially those containing ammonia or bleach, can react with grout and cause discoloration.

Bleach

For tougher stains, you can use a solution of bleach and water (1 part bleach to 3 parts water). Apply the solution, let it sit for 15-30 minutes, then scrub and rinse. Be sure to ventilate the area well and avoid using bleach on colored grout, as it may cause discoloration.
