Decorative lighting. This adds visual sparkle. Whitehead advises using a single pendant in a square-shaped bathroom for just the right touch.
Bright idea for dimmed lighting: To make the most of your lighting install the highest-wattage lightbulb possible then dim it down to accommodate the mood and lighting needs. Consider putting dimmers on both overhead lighting and lamp lighting.
A floor lamp nestled against a window is a smart substitute for daylight so that when the sun goes down an ambient glow will pour in from a similar direction to balance the central light overhead.
