Sunnats and aadaab of wudhu

Reciting wudhu duas in a joint toilet and bathroom

Q: I wanted to know about wudu in bathroom area. As you know in western countries (UK) Commode and sink and shower all in one, 3 piece bathroom. I wanted to know if I am making wudu in bathroom and I cover commode with lid, then I can read mustahab duas in toilets because dirty part is closed now though in same bathroom or in close vicinity or am I not allowed to read any duas there, while making wudu?

Reciting the duas when making wudhu in a joint toilet and bathroom

Q:

1) A person has a bathroom with toilet shower etc in one room. If he makes wudhu in the shower cubicle, with the transparent glass between him and the toilet, will it be permissible to read the duas and take Allah's name?

2) In the masjid toilets, there is a passage with many doors for individual toilets. Is the passage considered to be part of the toilets?

3) If the passage through next to the toilets leads to classrooms, which are also accessible from the masjid, and a person needs to carry kitaabs through to the classroom, should he use this passage or go through the masjid?

Making wudhu in a combined toilet-bathroom

Q:

1. Should I try to remain perpetually in the state of wudhu even if it entails making wudhu in a combined toilet-bathroom multiple times a day? The toilet is very close to the sink.

2. Is it correct to bring a Miswaak into a combined toilet-bathroom in order to just wet the end of the miswaak if this is also done multiple times a day? The toilet is very close to the sink.

3. Please advise if there is any change to the rulings in questions (1) and (2) if the sink was not very close to the toilet, but still a combined toilet-bathroom.

Khilaal of the toes

Q: Regarding khilaal of the toes, should one make khilaal of the toes of both feet together after washing both the feet or should one make khilal of the toes of the right foot after washing the right foot and of the left foot after washing the left foot? What is the sunnah method?
