Hello, I am new to this forum. Please excuse me for not knowing the right words for things. I am having a 2x4 Velux skylight installed. My roof is pitched, not flat. I have a flat drop ceiling. The opening in the ceiling was cut to 4x6, with the intention of having all 4 sides of the shaft flared out for maximum light. Now the installer is saying it can't be done the way we planned; he wants to flare the top and bottom, and keep the sides straight. I know I have read about skylight shafts with 4 flared sides - they are described as challenging, but doable. But I can't find any detailed diagrams or instructions. So my questions are: has anyone here done it? Can anyone point me to a description of how it's done? Anything that would help, even a diagram or photo. Thank you.

Ok....i had a tiled wall surround and it was old and ugly so i decided to replace it with a vinyl surround. I removed the walls and the tub and did the plumbing all new and put in a new tub The issue is this. The home had aluminum windows when i moved in which i had replaced with vinyl windows. There is a window in the bath and the sill was not level and leaked. There is no way i can level the sill (or tilt it in for that matter) w/o removing the window which is not an option. I am faced with having about 1/2" of space at the bottom and both sides of the window i need to cover. I was thinking of tiling it but I'm not sure that will work. I have seen trim kits that some of the surround companies make but i dont think that will work because it is such a small depth. anyone have any ideas or is tile my best bet?
