A Bathroom Fan

As with many things in this house, the fan was more complicated than one might expect. I first had to find one that would fit into a 3 1/2 inch space, and then find a way to make it work in a situation where there isn't a ceiling to set it into. (I decided against a wall fan because the wall is so thin and I wouldn't be able to put any insulation behind it at all).

I ended up boxing in the space between a beam and the dividing wall with the kitchen to make a lower false ceiling in a small area. This gave me a place to install an inset LED light as well (not in the picture) The vent had to go down a bit to go under the support beam that runs the length of the building. You can see it here with a box started to cover it up.

All done!
