Toilet basin size specification standard

The size of the hand washing table has some minimum control, the minimum width is 550mm, and 600mm on one side. In order to save space, the collective toilet has reduced the hand washing table to about 300mm, but even if it does, the washbasin can't be only 300mm wide. It's not convenient to place things if it has to highlight the face washing table. In addition, the key is to leave a 550mm clearance from the center of the washbasin to the walls on both sides, that is to say, there should be 1100 clearance to put your counter. Otherwise, it's poor to use, so you can synthesize everyone's opinions. There are also some in order to be more economical, or even do not wash the table, it is necessary to have a floor wash basin, put a soap or something.
