Help me bring light to a bathroom
We are in the middle of a house addition/renovation (framing done, rough-ins part way done, cladding mostly done). Now that we have added our addition, we lost the window that was in a small main level bath (the smaller bath on the top of the below image). There is now a floor above this bath too. We had hoped to put in a sun tunnel for this bath, but that did not work out due to locations of closets on the floor above.
Our latest idea is to add an interior window high up on the small bath wall (near where it is marked toilet) to try to steal a bit of light from the laundry room east facing window. The laundry room is ten feet wide, so the light would be coming from 10 feet away to the bath so not sure how that will work. The window in the laundry room is not exactly directly across from the small bath, so if necessary, I could investigate paying to have that window moved to the corner of the laundry room as the cladding material on that side of the house is not yet done. I am not sure about adding an additional window in the hall that leads to the bathroom due to cost.
The only other sources of light available to steal from other than the laundry room window, is a sun tunnel in the other bath on the bottom of the screen, a window near the bottom of the staircase, and a possible second sun tunnel we are considering placing in the laundry room which would be in the recessed area of the laundry room where it is marked storage, extra linen.
I would love your thougts and suggestions. If you do like the idea of an interior window between small bath and laundry should I also do an interior window between larger bath and laundry to say share the lighht from that bath sun tunnel to laundry (laundry is not all that bright) Would glass block be the way to go instead even though it is not done that much anymore.
Looking forwarding to your help.
