That's all complete nonsense. The Romans bathed a lot. They built bathhouses EVERYWHERE even next to most samller camps near Hadrian's wall. They were obsessed with bathing. Like someone said, they needed lots of water. Cologne (CCAA) for example had the same water consumption as today (with much less inhabitants!)
The process is the following:
oiling, scraping, then, hot bath or steam bath or both, then cold bath, normal bath, oiling with some nice smelling oils, done. Why do you think they built those huge baths in Rome and everywhere so that everyone could go?
"Of all the leisure activities, bathing was surely the most important for the greatest number of Romans, since it was part of the daily regimen for men of all classes, and many women as well."
check here, they even show Roman bikinis lol
