Hot Tub Folliculitis

Serving Hamilton, Stoney Creek, Grimsby and surrounding areas

Hot Tub Folliculitis:

  • Is caused by a bacteria called Pseudomonas aeruginosa which:
    • Grows and reproduces best at the temperature of most hot tubs
    • Is often not killed by chlorine or bromine
    • Is present everywhere in our surroundings
    • Even if it is eradicated from a hot tub, easily reinfects the water from the surrounding environment
  • May affect everyone who goes into the hot tub, but most commonly will affect only 1 or 2 people, even though many people may have been in the tub
  • Usually appears as very itchy bright red bumps and ‘pimples’ with yellow pus in them
  • The spots are usually located from the lower chest down to the knees
    • The face, upper chest, lower legs, hands and feet are almost always not affected


  • If the affected person stays out of the hot tub, the rash will disappear spontaneously after 7 to 10 days
  • If the rash is severe an antibiotic pill will help it to clear up more quickly
  • Drain the hot tub and change the water
  • Talk to your hot tub dealer about ways to eliminate Pseudomonas from the water
  • Pseudomonas is very difficult to eradicate and in some cases people can never get rid of it from the hot tub
