I was too tired last night to bother trying to work out the one in my room... seriously, you need an instruction manual.
The first surprise was to sit on a heated toilet seat... oooh… lovely.
And a public loo we visited on our walkabout was pristine, almost beautiful. I'm not sure if the waterfall music was to encourage you to pee or hide the fact that you were.
A person with whom I am travelling and who shall remain nameless, tried to push the flush button and ended up being squirted but couldn’t work out how to make the water stop so was stuck there unable to move until the realization dawned that you do have to stop the water flow. So far I've not been brave enough to push any buttons. You don’t really need to… the lid lifts when you walk in, the music starts when you sit down and it flushes all by itself when you stand up. Magic.
