I am a member of our local freecycle list and picked up a hinged mirror that will work awesomely well as the bathroom mirror with the wings acting as corner cupboard doors in our proposed guest cottage bathroom.
With the mirror over the sink the hinged wings of the mirror will be able to act as cupboard doors for the corner cupboards.
I’ll have to scale back the depth of the two corner cupboards, but that won’t be an issue.
The mirror has nice piano hinges holding the wings. The frame of the mirror is not solid wood. I think it might be press-board so I’ll have to sand the frame down really well, seal it with a good quality primer and paint it to ensure it holds up to moisture in its new position over our future bathroom sink.
