This year's (2016) home remodeling works are coming to the end, though one problem were left - a window for bathroom. 

As just outer constructions of walls were performed, and there are still a lot to do inside, before having actual working bathroom, I was left with two options, either purchase an used plastic window and install it or be more creative. I opted for the second variant. And as a temporary window I used old wooden doors.

These doors will be used as a temporary bathroom window for upcoming winter.
