Another important ceiling-based light source is the pendant or chandelier. The line between these two can be blurry as a chandelier is essentially just a large (and often more decorative) pendant light. Chandeliers also are more likely to have multiple bulbs (which help create more layers) but what is or is not a pendant is still a gray area especially with more modern fixtures like the one here.
Candles also offer wonderful sparkle and set a distinctly relaxing romantic tone. Just make sure you keep them well away from any flammable objects such as towels and hair and never leave them unattended.
All-around lighting includes general lighting and natural light. You want to ensure that at any time of day there is enough light for everyone to effectively use the space without incident and that any dark areas are minimized.
