Adding a pathing penalty if a route goes through a latrine/washroom

[Steve8]

I have the follow situation:

 

If I didn't lock those doors dupes will sometimes take a trip through the bathroom and needlessly wash their hands. Instead of taking the equally long green route. It would be nice to allow access from the left however.

I guess checking that all the time would come with performance problems. But maybe it could be simplified to just exclude actual washrooms. The room below with the two sinks would still cause issues, but that would be acceptable as an edge case.

They only wash their hands when infected with germs.

Indeed, dupes only use wash stations if they need to.

It's generally a good idea to make bathrooms a dead end alley, kind of like how they are set up IRL. That way you can 100% ensure dupes pass the sink on their way out.
