What are the cleanest countries in terms of how often people take baths and showers?

Here is a starting point for discussion, unclerk:

The title of "cleanest people on earth" may go to the Australians. However, research is difficult to come by on this point.

According to an October 2006 survey of 400 people conducted by EnergyAustralia (the supplier of electricity for much of Australia), every Australian takes at least one shower each day. Specifically, "62 per cent of people showered once a day, 29 per cent twice a day, and nine per cent showered three times a day".

These figures imply that no Australian goes more than a day without a shower. This is arguably the highest rate of national showering anywhere in the world and qualifies Australians as the cleanest people on Earth. The survey also found that women take slightly longer showers than men (but only less than a minute more) and teenagers take longer showers than people over age 40.

Addendum:

The majority of Russians (35 percent) take a shower or a bath on a daily basis. Eleven percent of Russian citizens take a shower twice a day. Residents of Europe turned down their medieval habit of washing themselves twice in a lifetime. However, they still prefer not to take a shower too often. The Britons and the Germans usually wash themselves twice a week.

The Hindus are the cleanest nation in the world. They wash their hands and bodies twice as often as Germans and 1.5 times as often as Americans.

A Hindu will always go to the bathroom after he or she sneezes, touches a pet or visits a toilet. This cleanliness is justifiable in India, for this is the country which intestinal infections find very comfortable for their existence. A piece of soap in the hands is the best protection against them in India.
