Wudhu

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.

Passing wind

Q: I have heard that passing wind being in the state of wudhu, breaks wudhu only if the wind has odour or sound. Otherwise wudhu remains valid. Is it true?
