- "with many small and seemingly impossible to clean nooks and crannies prone to leaking and harboring of bacteria"

Ahh! I've wondered for a long time why this specific issue doesn't have mass-market solutions. I thought it was intuitively obvious that contaminable surfaces need to be high-radius convex and easy to access, else you're wasting valuable time playing stupid geometry games. Who wants to spend their life cleaning bathrooms? Clearly, the engineers who design these things don't clean their own houses, and don't talk to the people who do.
