Assalamualaikum. i have copied some portion of the answer of question no. 7653:
Ibn ‘Aabideen commented:
What is meant by “a bathroom and kitchen” is bathroom facilities and a place for cooking that should be within the room or in a place which is not shared by any other family members.
(al-Durr al-Mukhtaar, 3/599-600)
I say: what indicates that what is meant by “house” [bayt – literally, “house”, translated above as “room”] is a room is the comment of al-Kaasaani (may Allaah have mercy on him): If the house has rooms, a room should be allocated to her and given its own door. They said: she does not have the right to ask him for alternative accommodation.
(Badaa’i’ al-Sanaa’i’, 4/34)
keeping respect to the reference source i am going to ask you some questions. i don't understand if there is anything else to do for a wife except sleeping,toileting & cooking that is why she doesn't need to move at all! i am sorry to say it looks like a little better version of a prison.. please forgive me. in a same house although a separate room is given,is it possible to avoid the expectations made by mother-in-law & others that their son's wife will do something for them?the daughter-in-law will must listen words from them that she is here only for eating,sleeping idly & doing romance with his husband inside her room not helping her mother-in-law at all. every moment she will be worried about what other peoples are thinking about her right now, is it looking good?..etc. then by which means she is free to relax in her so called OWN ROOM? dear brother,is it really possible to live in a single room all the day long through the whole life like this? hope to get answer soon.
