to not let neighbour use my shower!

I wonder if she thinks your more friendly than you do, with the dog walks etc.

I do think it's a bit mean not to let her use your shower at all...
Just give her a couple of days and times when she can. Say you can't accommodate her more than that.
But I really don't think you should not let her use it at all. I'm a massive introvert abd even I would try abd find a suitable time from a friend to use my shower if they really needed to.
Hopefully if you give her a couple of days she has other friends she could turn to fir the rest of the time.

Realistically, what is it costing you to just be nice and say yes? I wouldn't hesitate. She will be there for the length of the shower. You will have the house to yourself for the rest of the day.

I’d say yes, and just get on with the disruption.

Could you do once a week?

I was without hot water for weeks once due to kitchen being rebuilt, -I boiled kettles but at the time I had really long, thick hair that was a pain to wash in a bowl- My neighbour over the road offered for once a week, and someone else offered once a week, too- one can do bowl washes, and a shower twice a week is fine with bowl washes in between.

She might be a shower hog and use loads of hot water - plus someone else steaming up the bathroom.

Yes I think it’s a lot to ask for showers every other day until the week after next!

I wouldn’t mind accommodating someone two or three times but beyond that it’s a bit cheeky. What’s wrong with the local swimming pool? Or getting a temporary pass for the gym rather than inconveniencing others.

Sorry what nonsense is this? Everyone is entitled to their boundaries.
I would never ask a neighbour this. I would go to a gym or leisure centre or wash some other way.

I would find it really intrusive to have a neighbour in my bathroom. Visitors only ever use the downstairs loo. If I was off work there is no way I could be comfortable as a PP said giving them a key to let themself in to shower.

OP do what suits you. Less of all the poor woman must be desperate, she asked, you can say it doesn’t suit.

Favours I have done for neighbours include pet sitting and baby sitting, picking up food shopping, helping in garden, witnessing documents or passport forms, lifts to train station, helping kids with homework. But no, not my shower. I don’t think that makes me a bad neighbour.

Is it her shower or her boiler that’s broken?

I wouldn't hesitate if one of my neighbours asked. Its hardly a big imposition on you.

This would be a nightmare for me. I've got ADHD and something like this request would ruin my week. I'd be stressing if my bathroom was clean enough and worrying all day about when the neighbour would call. But even I'd say yes because I'd know it was the right thing to do and I couldn't articulate why this would be difficult for me.

I get it OP. I really do. Some people just struggle with stuff like this but I think if would probably sour relations so it's about weighing up which is worse for you.

OK, assuming she’s a totally normal and nice person, and doesn’t have any nearby friends or relatives - she’s probably pretty desperate for a good wash.

Assuming she’ll also provide her own soap, shampoo and towel.

I’d message - “Hi Neighbour, omg what a nightmare for you. Yes of course, does X time tomorrow work for you? Just knock on, and I’ll show you upstairs and how to work it. You can pop your towel and soap next to my things, no problem”.

But it’s completely up to you. You don’t have to allow her. But it’s the kinder thing to do, and assert your boundaries regarding times/days/bringing her own products.

To one side neighbour, absolutely, she probably wouldn't ask though, but I'd be fine with it. The other side no chance.

I didn't say I did, you were the one asking about letting her shower at yours.

you were the one bigging up volunteering in your defence of being called mean. I was merely say you can volunteer in one situation and still be unkind in other situations.

Christ no of course it's not "cheek" to ask a neighbour a totally reasonable favour.

If you don't want to do it just say no snd let her draw her own conclusions about the sort of neighbour you are.

(I've done this twice when I've had work done on my bathroom. My area is a bit rough around the edges but not the Wild West. Wouldn't hesitate to return the favour).

Does she still have hot water? You can get attachments that fit on your taps with a shower head? Not the old rubber version but a proper metal valve thing.
A tenner on Amazon.

I wouldn't dream of bothering my neighbour to ask!

Imposing 😂😂
Poor op for being imposed 😅

No, that's what you chose to do. It's not the only option!

Well by asking for this favour the woman has put OP in a difficult situation hasn't she?
OP has been given the dilemma of letting the woman use the shower, which she really doesn't want to do. Or refusing and worrying about how that will look to the woman.
That's what asking does: it puts people on the spot.
It's cheek.

I would say yes without hesitation, as I'm that kind of person.
However, in her position, I would probably look at showering at a local sports centre or gym before asking a neighbour.

I would never ask a neighbour this and I think I'd be baffled that she can't just wash without a shower, rather than putting someone else out. However I'd probably say yes. You might one day need a friendly neighbour who'll let you use her loo while yours is being refitted or something.

I think it is concluded from the fact that you are unwilling to help your neighbour.

Do you think it's realistic that nobody can fix her shower for two weeks? Do you live on Mars? In a semi-detached house with no other neighbours nearby?

I can't imagine asking that of a neighbour, especially if we weren't particularly close. I'd phone more tradesmen to find someone available earlier and would make do in the meantime.

Definitely not.
She can wash in the sink. I have done this before when our shower broke.
Also remember that our grandparents didn't have showers and somehow managed to wash themselves!
