In my experience, it's rare in North America for the bathroom or any rooms door to open outward, unless it's a closet. Most houses are designed with a straight, narrow, central hallway. Any door opening out presents a risk to anyone walking down the hallway, so closets are the exception. Bathrooms usually open out if they are too small to open inward.

However, never have I seen one designed like this. Doors usually are in a spot where nothing can obstruct them, and they are off to the side or end of a room where drawers and people using the room are unlikely to be near, so the likelyhood of a person blocking the door is low, much less a drawer built into the cabinet. This looks like one of those designs where an original two storey house was cut into two units by a do-it-yourselfer that didn't care about the result because they wouldn't be the one living in their disaster.
