Originally, the idea was to have wall sconces flanking the mirror and two matching (or at least complementing) pendant lights located roughly where the two old ceiling light fixtures were. It proved difficult to find pendants that fit our taste and our budget, so Jessica called an audible and decided that (recessed) "can" lights would be a better way to go.
It cost an arm and most of a leg to have electricians install five can lights in the kitchen last year; I tackled the bathroom installation myself. It certainly wasn't a trivial job (The tight attic space above the fixture close to the window was extremely restrictive and claustrophobia-inducing.), but it helped that I was able to use existing wiring, and I was done in an afternoon.
Obviously, they're not shown completely finished. Jessica recently installed the trims, and forthcoming pictures will reveal the finished product.
