The Sims AI is so stupid, all they know is playing games. Ask them to pee and bath they'll go to underground floor to pee and walk to upper floor to bath, unless you click the specific toilet and bathtub so they will not walking around to separate bathroom/toilet just to clean and bladder. I am playing on PS5 so it is a little hard for me to browse the UI so I always use the need interaction. So, having more than 1 bathroom is not a good idea as the AI is so stupid. They can make dozen of drinks and let it spoiled without drink even a single glass. And a lot more stupid thing they do, and they are so stupid. I suggest EA overhaul the AI to better one as the AI world now is evolve, but sadly not AI in The Sims.
