Asian bathrooms are not like American bathrooms, there is a nice drain on the ground, and all the surfaces are tiled. People soap up, scrub, and rinse without getting into the tub. They then fill the tubs up with water a few shades below boiling, and relax for a long time. So, you would already be sparkling clean by the time you got in the tub. Today, bathing is a resort activity.
People travel to famous bath resorts, and bathe for days.
These resorts are usually hot springs, and mineral springs, the type famed for health or something equally relevant. After waking up, you take a nice, long, leisurely bath. After the bath, you eat something delicious, or go to an entertainment room. These entertainment rooms have televisions, videos, games, and lots of earphones to maintain privacy. After some diversion, you go back and take another bath, eat, and soon for the entire stay.
