Would these mirrors look nice here?

[1sttimeonhere]

Small understairs shower and toilet room. Would these mirrors work?

No problem, please post the end result!

Maybe this is actually nicer, dimensions look
Perfect and it is just one piece

H 35cm x W 40cm x D 0.8cm

I think the round mirrors would work but I would only use 2 of them and have them spaced within the line of the window, so no part of the mirror sitting above the top of the window. So the 2 mirrors sit within the size of the window, if that makes sense.

The hexagonal mirror is nice, again 2 of them.

You could also get a standing mirror to sit on the windowsill and hand a picture on the wall. There's lots of nice standing mirrors about.

I would come up with more straight lines, to visually create more space
