Though time in the hot tub is often blamed for urinary tract infections, it is actually not a common cause of UTI and very rare that a long soak would cause the infection. Hot tubs, or even very long baths, can cause the spread of yeast, known as vaginitis, and common skin infections like folliculitis. In the rare instance that a UTI is contracted while in the hot tub the bacteria known as, pseudomonas are going to be the cause. This bacteria makes up less than thirty percent of UTI cases, as E. coli is the most common cause of cases.
Both infections present with similar symptoms and irritation so the one might be confused for the other and a doctor should be consulted in either case in order to gain a correct diagnosis and the best treatment. Even though time in the hot tub is thought to be a major cause of UTIs, women are more likely to contract the bacteria after intercourse, or through the use of diaphragms.
