Hot Tub Folliculitis (or Hot Tub Dermatitis) is a skin infection syndrome caused by contact with a contaminated hot tub. It is usually caused by a bacterium called "Pseudomonas aeruginosa". When people soak in a poorly maintained or inadequately disinfected hot tub, the bacteria enter the hair follicles or the stratum corneum of the skin.

Children over 2 years old: Can soak briefly in a specially temperature-controlled hydrotherapy hot tub. Water temperature not exceeding 37.5°C (99.5°F); time limited to 5–10 minutes; adult supervision is required.
