What is Hot Tub Rash?
Hot Tub Rash or dermatitis is an infection
of the skin.
The skin may become itchy and progress to a
bumpy red rash that may become tender. There may also be pus-filled
blisters that are usually found surrounding hair follicles. Because
a swimsuit can keep contaminated water in longer contact with the
skin, the rash may be worse under a person’s swimsuit. More about

What causes Hot Tub Rash?
Hot Tub Rash infections are often caused by the germ Pseudomonas
aeruginosa.
This germ is common in the environment (water, soil) and is
microscopic so that it can’t be seen with the naked eye. Most rashes
clear up in a few days without medical treatment. However, if your
rash persists, consult your healthcare provider.
How is Hot Tub Rash spread?
Hot Tub Rash is spread by direct skin contact with contaminated
water.
The rash usually occurs within a few days of swimming in poorly
maintained hot tubs or spas but can also be spread by swimming in a
contaminated pool or lake.
How can I protect myself from Hot Tub Rash?
Be aware that hot tubs and spas have warmer water than pools, so
chlorine or other disinfectants break down faster. This leaves hot
tubs and spas at risk for the spread of RWIs. Therefore, ask your
pool manager about the disinfectant and pH testing program at your
hot tub or pool.
Ensuring frequent testing, control of disinfectant (usually chlorine
or bromine) levels, and pH control are likely to prevent the spread
of dermatitis.
