Sims now more consistently wash hands in the sink closest to the toilet.
Fixed in Patch 1.99.264/1.78

This bug has been around in my game for years, before the date of the OP. However, I used a workaround, which now only works sometimes. So, this problems has gotten worse.
It used to be that if you put the sink on the right side of the toilet (when the sim is facing the toilet) problem was solved. This is no longer always the case, somtimes it needs to be on the left now. Switching which side the sink is on relation to the toilet works, however there is no dependable pattern anymore and I get tired of guessing and moving sinks. For example, one bathroom has the sink to the left of the toilet and the second bathroom may need the sink to be on the right or it may also need to be on the left. This happens on home and world lots. I've taken to using toilet stalls to solve the problem in world spaces and creating one giant toilet room with sinks. I don't use sinks outside of toilet rooms/ bathrooms. Sinks across from toilets always seem to cause me problems.
I now officailly have potty mouth. Must cleanse with coffee.
