I believe you guys totally missed the reason of her despair. There's no more rolls of toilet paper at all.
I don't see the problem there, she still has at least three paperboard cores to use. Oh, the sink is placed over the water tank. Probably kind of common over there but I find it a good idea.
It's entirely standard to have the water flow back into the tank via a sink; also, this toilet appears to not have a bidet function - since there's no controls (they're generally on the right-hand side) or remote visible.
