There is no need to boil water for bathing or showering. Adults, teens and older children can shower or bathe, though they should avoid getting water in the mouth or swallowing the water. 
Infants and toddlers should be sponge bathed. No special soaps are necessary. Care should be taken to prevent water from getting into deep open or post-surgical wounds.
