Instead of or in addition to sconces hidden lights can add a general glow that bounces off the wall and into the room in an even subtler and more diffuse way. Cove lights are built into niches that hide the light source (often a plain LED strip) but hidden lights can also be obscured by medicine cabinets shelving or storage units.
If you enjoy art in your bathroom accent lighting will show it off best. Recessed directional lights provide focused illumination for each piece of art — or in this case for an alcove dedicated to a sculptural bouquet of flowers.
Painting with light is another way to add surprise. Here colored LED lighting with toe kick lights underneath the island and cabinets creates dramatic appeal.
