Yank loos are bigger because the average American arse is quite large, OK? The pedestals are also braced to handle a much heavier average body. Architects guidelines for elbow room design in toilet cubicles were recently upgraded to accord with the larger average size of the American citizens.
The Yank toots I have had experience of are already full of water when you lift the seat. Great for teaching little boys accurate aiming because you throw in one of those puffed wheat target fish shapes and make a game out of it. Adults who sit, do their best to not wash their backsides as they deliver to the bowl. At the end, the user averts their eyes to the greatest extent possible and flushes. The soup in the bowl disappears and is replaced with a mostly clean recharge of water. A lot harder to leave skid marks on Yank toots but you can if you really try.
One common myth about American toots is that you use them by going forward in then back out. A recent South Park episode addressed the issue of how to use the toot properly. Forward in, back out is Russian style and used by Russian woman who often wear multiple layers of skirts and heavy coats but no underwear. A bit like the Scots and their kilts, no toilet paper is used and no need to wash your hands afterwards.
Why the interest, Dot?
