The guest bathroom has a skylight, which brings in gorgeous natural light, but no actual windows. I maximized the light by adding a full-length mirror to one end of the bathroom, as well as an oversized mirror above the sink. Both were purchased at the flea market.
Before Dana and her husband got to it, the bathroom was COMPLETELY mirrored! Yikes! The <a href="http://www.ikea.com/us/en/catalog/products/50038213/" target="_blank">rectangular mirror</a> over the hovering vanity is the only remnant of that.
