In the prizewinning loos at Heston, the basins were in a separate part of the room, with the loos down corridors with the space between the opposite doors larger than one door, if smaller than two - though I'm not sure about that.

I'm going to check out distances from now on. But I still think that there should be room for someone to stand in the loo and swing the door round without being forced against the seat.
