I'm a bit alarmed by all the talk of 'essential' stairlifts, downstairs bathrooms - and hoists. My friend came home from hospital and didn't have any of these things. Her little house had only a small sitting room and kitchen downstairs - as I'm sure many small houses do.
Out went the two sofas and sideboard, then in came a hospital bed, wheelchair and commode. The TV was relocated to the top of the fireplace (where she could see it) - and we sat on a couple of dining chairs.
She had carers four times a day, often in pairs, but one, the best by far, preferred to work alone. She was like a breath of fresh air, only tiny, but cheerfully managed to get my friend up, washed (bedbathed) and dressed, hair washed and styled, fed and watered, into her wheelchair, through the kitchen to sit in the garden.
She was a very good cook as well (the others being pretty useless. There is no 'rule' that it takes two to do transfers. The commode was emptied/cleaned in the upstairs bathroom.
My friend then had sleepover carers - having fallen out of bed at night a few times - and was happier, having never before lived on her own. Apart from hospital visits and stays, she lived like this for eight months, without too many problems.
