Unlike most caregivers who work at hospitals or nursing homes, Yu Liya does her job in a refurbished RV equipped with a bathtub.

"I am a mobile bathing assistant," the 40-year-old said. "We drive around and give baths to seniors who are incapacitated by age or illness."

Teaming up with another professional bather and an experienced driver, Yu is more like a coordinator. After getting orders from clients, she takes note of their requests, adjusts the temperature, gives health assessments before the bath and even comforts those who are not used to being bathed by strangers.
