My mum died this year aged 95 without thankgoodness suffering from dementia. But she did shower less as she got older (once a week). We were able to talk about this. She actually preferred to do what she called "a strip wash". She had a chair next to her hand basin and sat on this as she was a bit unsteady, she had two towels (one to sit on) and basically washed her top half. She did tell me that she found showering 'exhausting' and after her shower always sat in her towelling robe for over an hour until she felt better.
I don't know if this helps. All those of you coping with dementia have all my sympathy.
Water shortages and hosepipe bans

Reducing contact because my heart just isn't in it.
