@crinrict I'm not sure how they use dishwashers with it. My Sims will use the sink if the dishwasher is in use. The important thing to remember with that mod is to only use one of the files from the zip file, not both. I use the default enabled files so I can choose which cabinets or sinks to not use.
Can confirm this has been happening to me as well, sims even foregoing the use of dishwashers for sinks. Seem to recall this being an issue a few years ago.
I'm having the same issue but also I'm noticing it the other way around too!!!
I moved in to 2-4-3 Wakabamori and it was really noticeable there as the kitchen sink, the toilet and bathroom sink are very close and I've not just noticed Sims wash dishes in the bathroom sink, but Sims that have just used the toilet are using the kitchen sink to wash their hands! Not nice.
It has also happened on the same lot with a different build on and a different lot with a Teen and a Young Adult.
