They really did need two toilets. One between 10 people isn't enough for the workplace, so it's hardly sufficient when it's needed 24 hours a day. I might also be helpful if they have any of the plumbing problems they experienced last year.
The bedrooms are quite a way from each other, and bedroom one seems bigger. The living room is a funny shape too, and does leave some scope for partitioning. It's possible that they could still restrict the movement of contestants within the house even if it isn't fully separated.
They really are teasing us now. If nothing else I'll be tuning in to see what it all looks like.
