How to help mother with mobility issues at night?

My parents live in my house. They were independent when they moved here two years ago. Mother became severely ill seven months ago and has not recovered fully. Her mind is strong (she does not have Alzheimer's but my father does) but her body is weak. She is in a hospital bed with rails. She has a bedside commode. We have caregivers come in seven days a week. The one caregiver has suggested to my mother that she ought to have a night caregiver. I don't see the need for one because she can get in and out of bed by herself. I assist her until I go to bed. She usually does everything herself and she tells me if she needs help. My husband is adamant about not having another person in the house, especially in the evening. Having caregivers during the day is sufficient; there is a loss of privacy with this arrangement but having a caregiver at night is not acceptable. I don't want my mother in a nursing home and she would rather be here with family. I would like to know the best way to set up her area so that her water, tissues, and hand cream are within reach. My mother is very inventive and has devised many shortcuts but I am sure that others have dealt with a similar situation and would share what works for them. Thank you!
