Most Americans aren't aware of how different toilets in Britain are, even those who have traveled to the UK. Oh yeah, there are places you have to pay to use them, but at least they are available. Laurence Brown, with years of experience living on both sides of the pond, is very aware of how our toilets are different. And our sinks and bathtubs, for that matter. The toilets actually use different mechanisms for flushing. He doesn't mention which system uses more water, but that's not really a concern in Britain, which is geographically consistent and it rains all the time. Now that I'm in the know for watching this, it's my opinion that American toilets are superior, with the exception of having to plunge or snake them occasionally, which is honestly not often enough to be a bother (your mileage may vary). American sinks and tubs seem to be better as well.
It's somewhat amusing to hear how he talks about toilet efficiency without using any rude words. There's a skippable ad from 2:55 to 4:10.
