What is the minimum partition size of the bathroom?

Generally, the smallest toilet is about 70CM high and 62cm long, but at least 80× 128 should be reserved for putting the toilet, and 80 is the comfortable size for stretching your legs when sitting and squatting. And 128 is the minimum size of leaning forward when squatting. In fact, the toilet is not always fixed, which depends on the space area of your bathroom.
