Love the skylight!
My small (approx. 1300 Sq ft) two-story house has three bedrooms and a very small bathroom on the second floor. The bathroom has no window, and I finally got tired of having to flip on a light every time I entered the bathroom. A couple of days ago I had a 10" Velux suntunnel installed in the bathroom. It is WONDERFUL! Now during the day the little room is so bright I automatically reach for the wall switch to turn off the light and then realize I don't have to.
I had a wonderful contractor who did the job, with a helper, for $178. As the sun tunnel cost $175 I got the whole job done for less than $400.
