What should you know about folliculitis after a hot tub?

Warm shared water can allow germs to multiply when cleaning or circulation is inadequate. A hot-tub-associated rash may appear as itchy red bumps or pustules around hairs, often where a swimsuit held water against the skin. Heat, friction, products, or ingrown hairs can look similar.

Stop using the hot tub while affected and shower gently after water exposure. Change out of wet swimwear, avoid sharing towels, and do not squeeze or scratch. If the rash is extensive or does not settle, a clinician may consider targeted care, including Antibiotics For Skin Infection.

Arrange review if bumps persist, spread, become painful, or drain. Seek prompt care for fever, chills, marked swelling, severe pain, or feeling unwell. People with reduced immunity should seek advice earlier.

Ask whether the rash fits hot-tub folliculitis, whether testing is needed, when swimming can resume, and how to protect irritated skin during future water exposure.
