> Denmark loves their 'wet' bathrooms in hotels, no shower door and a drain in the center of the room.

If you're renting an apartment in Shanghai, a cheap one will have a door to the bathroom, but the shower won't be a separate fixture. The entire bathroom functions as the shower (the hose or fixed piping is mounted on a wall), and there's a drain in the floor.

A more recent apartment will have a shower installation that is, say, separate from the toilet.
