Appliances break very easily

Is it normal for your bathroom to break frequently, like every week, even after upgrading all of them? 

I play base game and started a new vanilla save after the latest patch and noticed that my toilets/bathrooms frequently break. Until this new save, I’ve been playing in a small house with small family so I barely noticed the constant need to repair/replace my stuff even without upgrading any of it. But this time, I play with the Goth and Spencer-Kim-Lewis households, since their house has more bathrooms and more sims, I wonder if the breaking is actually normal? As in the frequency of sims using the bathroom is higher, so have higher chance to break? Even after upgrading it? I don’t have clumsy/evil/mean sims or sims with high mischief in the household, only childish and goofball in Kim-Lewis household. Only the bathrooms keep breaking, no issue with TV/radio/computer/stove/fridge. About 42 days in Goth household, computer and fridge broke down twice, stove I think only once, but bathrooms were like once every few days.

This is the first time I got really annoyed with the frequent repairs that my sims need to make. Never experienced this issue before. But I’m not sure if it is actually a bug from latest patch since this is the first time I’m playing with bigger family in big house.

I play on PC through EA app, on latest patch. Only have base game, no packs or kits. Already cleared the caches and repaired the game after the latest update.
