My 87 year old mom broke her ankle in February. I dropped everything and moved in with her for a month. She was completely wheelchair bound --both in the house and outside. Her home is an old 1850s house but she does have a bathroom on the main floor. She slept downstairs on the couch because she refused to have a bed moved downstairs. (even though there was room) We used a potty chair at night, but she was able to use the downstairs bathroom during the day (she could transfer from the wheelchair). You would need to use the potty chair full time. I was fortunate in that my sisters took over on weekends when they were off so I could go home to spend time with my own family.
The elderly do best when in their own home. It certainly would have been nicer for me to have her at my house, but she would not have been nearly as comfortable. After the one month mark, mom was able to maneuver enough to manage on her own. Your mom would probably need the full six-eight weeks of help. I have no regrets in doing this for my mom, even though my life went on hold. She will not be with us that much longer, and it's the least I could do!
