So, here's a question for you. Are walk in shower cubicles a European thing? I believe the French call them Douche à l'italienne.
I have one in my larger bathroom. It looks very similar to this:
Although it is designed not to let water out, we have very good water pressure and I've had damage caused by people taking long showers with the water on full blast, somehow not noticing that they are flooding the bathroom. Now, I mention this to all guests when they check in and it hasn't happened since.
However, one Chinese guest seemed absolutely baffled by it. She insisted that all showers in China have doors and refused to use it. I didn't put this down to culture as she was odd is so many ways and none of my other Chinese guests have ever seemed surprised by this.
Then, yesterday one of my American guests came rushing down to find me because she had accidentally pushed the smaller panel of glass out of it's fixings and away from the seal. There is now a big gap between the glass. She said she thought it was a door. Odd because what would be the point in having a door that only went a third of the way across? She really didn't understand why there was no door (even though I had gone through the whole 'don't flood the walk-in shower' chat with her on check in).
Do they not have walk in showers in the USA? I really can't believe that. They are hardly a novelty, but are considered a bit of a luxury as you need a bigger space for them. Still, when I reiterated that it was a WALK IN SHOWER and quite normal, these guests looked at me like I was some kind of cheap skate for buying one, as if I couldn't be bothered to pay for one with a door!
