And that is totally cool - it's great that OP has found this sub.

I’ve got a picture of the damage but not the whole area, I’m not there at the moment I’ve had to drive like 10 minutes away just to get internet signal

I am pretty irritated. I went from having never touched a spanner to being a race mechanic because I rebuilt a bike I’m a firm believer in learning by doing.

She has no interest in doing anything like this and expects me to do it all yet if I do something wrong I get it in the neck it’s actually bullshit

Sometimes it takes people some time. I grew up in a trailer and wasn’t exposed to certain things about real houses. My dad was handy but had close to zero interest in teaching me. My wife and I’s old house has basically been 16 years of hands on training.

Picture of the entire area?

Done

What? Says the guy that just put a big hole in his wall. Hahaha

I think this is a lie we are told by society. It only serves capitalism. It's a lie that takes away from you as a human being.

I think we all have within us the ability to do the things needed to go about out lives (physical disabilities notwithstanding).

Anyone can (and should) learn to paint a wall, put up shelves. change the oil on their car, fix a leaky gutter, unblock a drain.

Specialisation is great for more complex skills, and especially for skills that take years to master. I don't think anyone should do their own surgery. But I do think everyone should be able to put up a medicine cabinet.

Cut and sand, polish (two) plank(s)large enough to hold the cabinet. Looks better than raw wood. Anchor plank to and running across the studs each side of where you want the cabinet to hang.

Bolt the cabinet in to the board.

BTW, it sounds like you're pretty irritated. Maybe the first step is to take a deep breath and ignore the problem until everyone is calm?

I disagree. He accepted the task, so he's responsible for finishing it, one way or another. Suppose you hired a handy person to do this, and they got to this point and gave up. You'd be pretty upset with them for wrecking your wall, right? Even if they didn't demand payment, you'd probably expect them to at least put it back in order. This situation is a great illustration of why we need to be careful about committing to take, but is also a great chance to learn to do the right thing, even if it's difficult or expensive.

Bet at least one person wasn’t walking quite right after that session.

Maybe his skillset is in a different field? I can't fix a car, but I'm pretty decent at most basic home improvement things. I'm not a coder, but my houseplants are healthy.

Just about everyone has things they're good at, and things they're not. Just because someone doesn't have the same interests or abilities that you do doesn't make them less of a person.

Make hole for mount. Cover with cabinet. No fixy fixy

The problem is I’m not sure if I’m allowed to drill into the breeze block because it’s between me and next door

What do you mean?

I don’t mind true drywall but this is drywall and then 20mm air gap with breeze blocks behind it so literally nothing works

That's bad. How did it happened? I hate drywalls !

Okay. Wouldnt the drain go next to the expansion joint?

Only if you damage outside of the area you are covering with the cabinet.

No, they’re not worth the money to me

They’re not where I need them though

I’d guess about 20mm ish
