Glad you are having a good stay, a very interesting bathroom setup, but that bathtub...... oomph i need to devise an elegant way to plop in and climb out.
Can't spot anything to cling myself on to hinge myself out.
Anyway i can envision myself already on the floor in an X if the bathroom floor is slippery ....
Maybe i just need to loose weight and retake a course in acrobatics.
Youtube knows me by now, i get presented with recommendations:
"SENIORS: How To Fall Safely Without Injury".

Enjoy your time in HKG, wishing you a happy Chinese Lunar New Year !
