Translation:I still have not showered.
洗澡，洗浴 一樣的。浴室 is as much a bathroom and "shower room".. The Chinese don't make any difference. You should know that in different provinces and places in China, people have naturally developed different vocabularies designating a same thing/object/situation. China is a vast country. Like anywhere in the world, take Russia, You'll discover a similar situation. Even travelling through France you'll find that. Between Belgian, Swiss and French French has differences in calling a same thing. Regards to all
