I have a 5 foot by 9 foot bathroom with 8 foot ceilings and I am going to put a Velux solartube in it. I had someone recommend the 10 inch one which is fine but I was thinking about going with the 14 inch. He said it would be "overkill" but I thought it would be better to have as much light come in as possible.
I don't see the difference in the 14 inch vs if I put in an actual skylight.
Perhaps someone can help me decide the 10 vs the 14 inch size.
