ᐅ Mount a Flat Bathroom Mirror Flush Against the Wall

Hello everyone,
we would like to install a bathroom mirror as close as possible to a plastered wall without any gap.
Do you have any experience or tips on the best way to achieve this?

Regards

The simplest mirror holders already fit snugly. Isn’t that enough?

Otherwise, there are recessed mirror cabinets. These are also very flush, but you hardly find any under 2000€.

Or, depending on the size, fully bonding the mirror to the surface?
