As you'll notice there is no bathtub nor shower curtain. The door had a lock so we had privacy but still it felt weird. And it also made the floor feel yucky whenever we went later in the day to use the toilet or sink since it was still all wet from someone taking a shower.
In HK, it seems that most places have a western style toilet but the showers are still similar to this style. My bathroom is not like this and I've got a bathtub and shower curtain.
