Do I need two doors between my kitchen and a toilet or bathroom?

In the past people have thought that a bathroom or toilet couldn't open out into a kitchen, but this isn't the case.

As long as there is a basin where people can wash their hands before returning to the kitchen, then one door is enough.

And you don’t need a lobby.
