How far away is the toilet in the bathroom?

The question is not clear. If you ask about the distance between the toilet and the wall in the bathroom, there are two standards in our country, one is 30 cm and the other is 40 cm. Both refer to the distance from the center of the toilet drain to the wall, but pay attention when choosing a toilet if the wall is too thick when the bathroom is renovated (for example

First, the wall after construction is "leveled" with a thick layer of cement, and then pasted with a layer of thick tiles. It is possible that the toilet that could have been installed could not be installed because the distance to the wall was not enough.

If asked, the distance between the two toilets in large public toilets is usually more than one meter.
