An unusually shaped mirror can keep a basin useful without filling the wall in front of a window. In our Aberdeen bathroom, the custom mirror fits beneath the stairs and leaves the window uncovered. The basin sits below the slope with two drawers beneath it, while the shower uses the taller side of the room.
The useful mirror area is the part that catches your reflection at the basin. For a similar design, mark eye height and the actual standing position, then look at how the remaining wall shape and window line affect the outline. Compare where the mirror would end and what it reflects from that position. It also helps to look at the basin with daylight and with the lights you expect to use after dark. The aim is a reflection that serves everyday washing and getting ready while leaving the room's existing daylight opening available.
