The hand-held bidet is ubiquitous here. They're even common in public toilets - the first one I saw was in the Helsinki airport after I landed. Here's the one in my bathroom:
As you can see, it's attached to the sink. You turn on the sink tap, ADJUST THE TEMPERATURE, then push the button on the sprayer.
To be honest, I didn't know what this was when I first arrived here. Thank you Internet. I won't go into further details, but trust me, it is a very good thing that North America should adopt widely and I will miss it.
On a related subject, in my time here I've gotten used to referring to the "toilet" because people looked at me oddly when I said "washroom".
