whats stopping you installing one there ? I've one here at my home in the Uk - only thing to be aware of is in Asia it's usually just feed straight from the cold mains pipe I'm told ( which is generally warmish anyway) whereas here in the UK that would of course freeze the arse of you so they connect it to the warm pipe - but then need to fit a thermostatic control inline between the pipe and the bum gun itself to stop you roasting the ass off yourself ! Aside from that one fitting issue it works exactly the same as the Asian ones - I actually got it fitted years ago and my asian BF thought all his christmases had come at once when he first visited my house after and noticed that I had one ( as it was the first one he'd seen here in the UK)
