Are there people who consider the opinion of various authorities when they decide on bathroom behavior? Apparently this is the case - recently, in the "government in your bathroom" category, there was this: German man went to court, won the right to pee standing up. Meanwhile, back in Turkey...
Turkey’s Directorate of Religious Affairs (Diyanet) has released a fatwa stating that usage of toilet paper is permissible within Islam, though it emphasized that water should be the primary source of cleansing.
Reminding that for a prayer to be religiously legitimate, one’s body, clothes and the place where the prayer is to be performed should be free of items defined as “unclean” by Islam, the fatwa said the cleaning should be conducted with water.
“If water cannot be found for cleansing, other cleaning materials can be used. Even though some sources deem paper to be unsuitable as a cleaning material, as it is an apparatus for writing, there is no problem in using toilet paper,” read a part of the statement.

Here's my favorite quote on the subject of toilet paper, from Lord Chesterfield's Letters to His Son (to his illegitimate son, that is; he (Chesterfield) was trying to raise him (the son) above his (the son's) lowly origins and inferior blood):
"I knew a gentleman, who was so good a manager of his time, that he would not even lose that small portion of it, which the calls of nature obliged him to pass in the necessary-house; but gradually went through all the Latin poets, in those moments. He bought, for example, a common edition of Horace, of which he tore off gradually a couple of pages, carried them with him to that necessary place, read them first, and then sent them down as a sacrifice to Cloacina*: this was so much time fairly gained; and I recommend you to follow his example.
It is better than only doing what you cannot help doing at those moments; and it will made any book, which you shall read in that manner, very present in your mind. Books of science, and of a grave sort, must be read with continuity; but there are very many, and even very useful ones, which may be read with advantage by snatches, and unconnectedly; such are all the good Latin poets, except Virgil in his "AEneid": and such are most of the modern poets, in which you will find many pieces worth reading, that will not take up above seven or eight minutes.
