That's the more recent thing here in the US, too - especially in shopping malls.
Near the food courts, usually - you'll have the standard men's room and ladies' room, with the little wordless icons of a sort of stick figure for the man and a dress-wearing stick figure for the woman
.
And then you'll have the "family" restroom. It's a single room, big enough for several people and/or a baby stroller, etc. Sometimes it has one toilet, one sink, and a diaper-changing shelf or counter. And sometimes it'll have a regular toilet and an itty-bitty one for the little kids, as well as a "big" sink and a "little" sink. It's nice if you've got multiple small people, or if you're a daddy with a little girl - my husband used to hate taking our girls into the men's room, but wasn't comfortable letting them go into the ladies' room alone.
n more remote areas, we have "Sanikans" and "Outhouses".
...Also euphemistically known as "no indoor plumbing."
