Hot Tub Rash – What It Is and How to Beat It

If you’ve ever stepped out of a warm soak and noticed red, itchy bumps, you’ve likely experienced a hot‑tube rash. It’s not just a minor irritation; it’s a skin infection that can spread quickly if you ignore it. The good news? Most cases are easy to prevent and treat with a few simple habits.

Why the Rash Happens

The culprit is usually a bacteria called Pseudomonas aeruginosa. This microbe loves warm, moist environments with low chlorine or poor pH balance – exactly the conditions you find in many public hot tubs and even some home spas. When the water isn’t kept clean, the bacteria latch onto the skin’s outer layer, causing a red, sometimes painful rash that can look like small blisters or a sunburn.

Other factors that raise your risk include staying in the water for more than 20 minutes, having an open cut or scrape, and using a tub that hasn’t been cleaned for weeks. In places with high humidity, like Dubai’s luxury spas, the problem can show up faster if the maintenance crew skips regular water testing.

How to Prevent and Treat It

Prevention starts before you soak. Always shower with soap and rinse off any sunscreen, lotions, or sweat. This removes debris that bacteria love to feed on. When you’re at a public spa, ask staff how often they test the water and what chemical levels they maintain. A properly balanced hot tub should have a chlorine level between 1‑3 ppm and a pH of 7.2‑7.8.

If you’re the owner of a home hot tub, test the water at least twice a week and shock it regularly to break down organic matter. Replace the filter every three months and empty the tub completely at least once a year. In Dubai’s desert climate, high evaporation can throw off chemical balance fast, so keep a close eye on the numbers.

Got the rash? Rinse off the hot tub water immediately with fresh, cool water. Pat your skin dry and apply an over‑the‑counter hydrocortisone cream to calm itching. Antihistamines can help if the rash feels especially itchy. If the bumps turn into pus‑filled blisters, spread quickly, or you develop a fever, see a doctor – you may need a short course of antibiotics.

While you’re healing, skip the hot tub for at least a week and avoid scratching, which can push the infection deeper. Loose cotton clothing and a gentle, fragrance‑free moisturizer will keep the skin from drying out and cracking.

Remember, a hot‑tube rash isn’t a sign you should give up soaking altogether. With clean water, a quick shower before and after, and a watchful eye on chemical levels, you can enjoy a relaxing dip without the unwanted side effects.
