Basically, counter gets dirty more often, clogged up toilets, etc?
I want my gameplay to be challenging!
Why just you don't buy only cheap furniture? Those less performing. As for instance a stove with 4/5 point for food, a 2/3 relax bathtub , a less points bladder for toilets etc. They will break easily.
I do not have any slob sims but my furniture broke so easily.
