Here is a piece I designed and built for my parent's guest bath. They wanted a high end look, but had a very limited budget. 

Materials: Ikea Varde Shelf, Generic 6 blub vanity strip light, Plexiglass
Cost: $130.00

As you can see, it really compliments the design of the bathroom.

Here you can see the cheap fixture as the guts of the piece.

I used this ikea wall shelf to match the existing wood/finish of the other pieces in the space.

Some initial concept sketches.
