Re the extenders, the rolls are too thick, not too wide.
The extenders are for thickness, not width...at least the way I'm thinking about it. They extend the spindle away from the wall, so there is room for a thicker, larger diameter roll, not one where the paper itself is wider (across in the direction of the perforations). Although I suppose they're also a tiny bit wider, too, but they're made to use the same spindle you already have, just to give it more space away from the wall or the back of the niche.
