Besides sitting vs Squatting, the other (and more important) issue with the western style toilet is the use of "papers" instead of bidet (water hose) for cleaning after oneself.

At home we always install a home-made bidet: usually a water hose connected to the shower somehow with a mechanism to turn it on/off.

When I'm in a public place, I try to avoid using public bathrooms. Sometimes I can't avoid it, like when I'm at work.
