Mum wants extra bathroom installed in my house

[lifestyleguru]

Please tell me what you think.

I live 10 mins away from my 72 yo old Mum who lives on her own. She suffers from depression.

I work as does my husband, we have 2 teenagers with additional needs.
I am currently undergoing cancer treatment.

My Mum says she does not come around that often because our stairs are too steep and she cannot get up them. She has arthritis and usually walks unaided. When she is over, we help her up the stairs and she always get there. Before she was less mobile, she did not come round much because she doesn’t like stairs.

Over the past couple of months she has said how upset and angry she is that we have not installed a downstairs bathroom for her, or even supplied a camode ( I don’t know where we would put that). We are doing up our house a bit so we can sell in a year or two but spending what we need to.

I am finding this really stressful and I don’t know what to do. Thanks.

Is it seriously not a massive job or expense? Digging up the floors, demolishing the kitchen, building new walls, putting in drainage, rebuilding the kitchen, new flooring? How can it not be massive? Where do people put a new downstairs loo? A relative of mine did make enquiries about putting one under the stairs and they were told they couldn’t because there wasn’t enough headroom.
