How is this commode style toilet seat called in Chinese? As I am disabled, I thought, in case my Appartment doesn't have a western style toilet, I might want to buy one of these:


So I wonder what they are called and where one could hope to buy them. If the university provides free Appartments I thought it impolite to insist on a Western style toilet.
坐便椅 can be the name you want, in a decent way.

In addition you can find it in Aliexpress. Some big pharmacies also offer these.
