There is no set rule on how high a shelf should be hung over a toilet. A good rule of thumb is, high enough that no one will hit their head.
Only if you want brown towels that hookers have been touching with fruit juice on their hands
There are many factors that need to be considered to answer this question. Insufficient data not provided. What is the type of towel that will be hung from this towel bar? Guest towel, hand towel or bath towel? For most guest or hand towels you want to divide the length of the towel by 2, add 3 or 4 inches so the towel doesn't contact the toilet tank top. Also consider that gravity factors into it as well. Ideally, the towel should not hang any higher than the shoulder of the average person using the towel after washing their hands. This is to keep the water on the hands from dripping down the sleeve of the person using the towel. Then consider the aesthetics of having a decorative item (Guest soap basket or a small floral dish or basket) on top of the toilet tank. Also consider hanging a small picture above the towel bar to balance the effect. There is no direct way to answer the question, just a few hints to consider what will be functional, easy to use and add to the overall design of the bathroom.
A common placement is about shoulder height of a normal sized person. If you are going to put bath towels rather than hand towels on the bar, then you may need to go a little higher.
Sure, but make sure that there is protection for the wall behind it, so that the bar does not accidentally punch through the wall. However, if the door is a hollow door, I am not sure how much weight it will hold or how you would put in anchors, since the wood is not very thick. There was a towel bar on the wall behind a door in one house that I lived in and it worked okay.
The exact instructions for installation of a towel bar will vary depending on the model of towel bar (if there is one), and the makeup of the bathroom. However, such installation is generally quite simple, and involves a drill, screws, and screwdriver.
The standard hanging height for your towel rack seems to be 48 inches above the floor. This will leave leave enough space below the bars for towels to hang freely. If, however, you hang the towel bar in a children's bath, place the bar at a height of 36 inches.
standard height is 36 inches and if there is available wall space you should put it as close to the sink or shower/tub as possible.
If one is extended from the wall more than the other that one should be set about chest high then the one closer to the wall about 6-8 inches above it. otherwise they should be about armpit height.
A ceramic of plastic towel bar will never corrode, a stainless steel bar will likely not corrode either.
A towel bar can be mounted to a vanity if it has a solid surface that can accommodate screws or nails. This can be done on the side of the vanity using the appropriate hardware.

You can use non-expanding base to fix a block inside a hollow core door to give the towel bar extra strength. Screws can also be used on the door to give the towel bar strength.
Brass does not oxidize easily, and a brass towel bar if properly plated will not either.
