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?
