Downlights are great for bathrooms, but ideally they should be IP rated against moisture.

If you wish to apply makeup, then mirror lights and sconces are good - make sure there are multiple lights and on both sides of your face. Also use pearl globes rather than naked ones.

Pendants can really lift bathrooms, which can be rather dull.

Heat lamps may seem old fashioned but can be really useful to heat up bathrooms, and provide light as well.

In terms of makeup, I would say not only lights on both sides of the mirror, but also on top.

Also make sure that makeup lights have high CRI (colour rendering index).

Use cool White light (3200K to 4500K)

Vanity lights across bathrooms walls are a must!

Don't forget lighting into showers. Many bathrooms omit this and as a result the shower is dark and uncomfortable. A waterproof downlight is good for that.

In front of the bathroom sink, you will want light that doe snot have shadows.

Also, don't forget about dimmers, particularly if you take baths.

For baths, lights at both ends is ideal - and very romantic!

Black downlights can give bathrooms a very modern look.

Try to use marine grade metals or polished metals with finishes, and avoid metals that corrode quickly like antique bronze and antique brass.
