When you need to!
It is bad for your body to wait on these things.
In all seriousness, are you meaning how often should you run water through it such as a vacation house?
Not sure I understand this one, and I was on such a roll!
Only if it is leaking there. They do sometimes, but not that often. If you have taken the tank off for some reason, you should probably go ahead and change it.
You should throw it in the bowl. That is the correct place for it, just not huge clumps of it.
If the toilet is sitting solid on the floor, you don't need to. I would use latex instead of silicone because if you should ever have to pull the toilet, it would be much easier. One reason not to seal it down would be if the wax ring should ever fail. You could have a lot of damage to the floor before you noticed the leak.
A bidet
Urinate and/or defecate in it, then flush.
A Plunger
You always should after you use it.
Yes, every nationally, every race, and every person should use toilet paper.
Usually, most people will only use one type of toilet paper and then maybe a baby wipe as well. You will have to find the toilet paper that is right for you.
The replacement of a toilet brush will depend on how often they are used. In general they should be replaced at least every six months but in some cases if used a lot they should be replaced sooner.
You should make certain that everything in the house is cleaned and sanitized -- use a good antibacterial cleaner on any surface the sick person has touched. Everyone should wash their hands often to keep from spreading the germs. Clean the seat of the toilet with antibacterial cleaner frequently. Make certain the sick person washes their hands every single time they use the toilet.
Wholesalers such as Costco and dollar stores will often sell common goods, such as toilet paper, for cheap. Another retailer that sells cheap toilet paper is Target. One can also make use of coupons and sale offers to buy cheap toilet paper. Store brand toilet paper is also often cheaper than branded alternatives.
Depending on where you are and what you're doing, you should go to the nearest toilet or restroom.
Only if it is leaking there. They do sometimes, but not that often. If you have taken the tank off for some reason, you should probably go ahead and change it.
Ask a grown up or sit on the toilet and let pee or poop come out and then their should be a handle or something and push or pull it, and wash and clean yourself.
Unless it is a very strange arrangement, turning off the toilet on the first floor should only shut off the water to that toilet. It should have no effect on the upstairs shower.
Yes you can. It simply means you would need to use the toilet more often.
