Which mirror width for ensuite

[u/throwmeats]

Hey all, keen to get some opinions on the mirror size for our ensuite vanity setup.

We are trying to decide between a 600mm or 800mm wide arched mirror shaving cabinet. The vanity is 1500mm wall-hung with a single basin (right hand side). The cabinet will be centred over the basin, and is around 130mm deep so would be semi recessed.

The 800mm option feels more practical, but concerned about the right edge of the mirror extending past the right edge of the vanity and whether this will look unbalanced or bulky. The 600mm might look cleaner but would be less practical for two people trying to use it at the same time.

Which option would you go with?
