Our Aberdeen bathroom has a bath, basin drawers and an extending mirror. An extending mirror changes the relationship between the user and the basin. You can bring the reflection towards you for a close look, which can be helpful when the basin or worktop already keeps you some distance from the wall.
Decide where you will actually stand before choosing where to mount it. Check the view with the arm extended and folded back, and think about whether you can reach it with a drawer open or a toothbrush on the counter. Then look at where the room light comes from when you are facing the extended mirror. Testing the reflection in its working position gives you a better basis for the decision than checking the folded mirror against the wall. It also helps protect the basin space for ordinary washing.
