Tiny ant-like bugs that can be found sometimes in bathrooms are most likely springtails. They are found in area with too much moisture and can indicate there is mold nearby. Keep your bathroom dry to avoid getting springtails.
There are small red bugs called "milkweeds", but they are only just hatched and still in the baby stages. They could be getting into your bathroom through really small holes that you might not even know exist in your bathroom, and they are not poisonous or anything, so they aren't harmful to humans.
Silverfish often tend to hang around in the bathroom at night and then scarper in front of you in the morning when you first turn the light on. Check out a picture of them on wikipedia.
I dont know. But water bugs only swim.
Tiny black bugs you find in the bathroom sink are referred to as drain flies. They are attracted to stagnant water in the drain and need it to reproduce. Having your drains cleaned can help get rid of the problem.

Of course! Contrary to popular belief, bugs do indeed use the bathrooms. After all, why would a bug just go to the bathroom where ever they please? Bugs - like humans, share a common need to use the bathroom. Bugs don't use regular human bathrooms, instead they build their own tiny bathrooms. Each species of bug builds different sized bathrooms. (an ant bathroom would never work for a tarantula) A regular bug bathroom consists of a urinal (for male bugs) and a toilet - (sometimes they build showers and sinks but this is a rarity) Bugs also use the bathroom up to 9 times per day! Although I have researched the topic of bug bathrooms for over a decade, I am still discovering amazing new facts about bugs and their bathrooms. I hope I helped, and I hope you learned something new about bug bathrooms.
