Stuck in the bath

[Golem]

I'm trying to find a short story about an elderly person who lives alone (I think she is a woman) and who doesn't have the strength to get out of the bath. She considers her situation and how the bath tub may eventually become a coffin to her. I thought it was by Janet Frame but can't find it among my collection of her work. Can anyone help?

Thank you Fibonacci. I guess I need to go back and look again!
