Mirror in front of a window

[DillyDallyingAllDay]

Hello all!
My downstairs cloakroom doesn't have much space and the sink is under a window. I'd like to have a mirror that you can look in while at the sink, and would like to do something like the image. Does anyone have any creative suggestions as to how you could achieve it?

I wouldn't want to block out the light / view from the window. Could the mirror go to one side of the sink instead? Or, if there's a window sill, could you have a small free-standing mirror behind the sink?

Unless it’s a very light room I really wouldn’t want to block more light. Is there an adjacent wall the mirror could go on (mine is on the narrow wall to the left of sink & this works fine).

Or even on the back of the door?

What about something like this?

I think I’d just put a standing vanity mirror on the windowsill. I’d worry about blocking light and also being able to clean the window behind the mirror.

Due to the positioning, there's actually quite a lot of light and I don't think I'd mind blocking some of it to accommodate a well placed mirror.
I wondered if anyone had any ideas for actually achieving something like the images? If I wanted it custom made, who/what trades person is likely to be able to help?

Absolutely something like this would work- is this available to purchase? Or is a freestanding vanity type mirror that has been mounted onto the wall?

Amazon have the pp wall mounted mirrors for about £200 ; there's also this
