Answered by Shaykh Faraz Rabbani
Is is optimal to pray throughout the house, or to have a specific room/area set aside for praying, or does it make no difference?
It is recommended for both men and women to have a place set aside in their house, free of things that busy one’s mind and conducive to serenity and contemplation, which one considers one’s place of prayer (musalla). [Ibn Abidin, Radd al-Muhtar]
Women can perform their spiritual retreat (i`tikaf) there, though not men. [ibid.]
