Mixing metals....specifically in a bathroom.

What is allowed?

When is it too much?

What metals should never be mixed?

I love this mirror (only comes in black). I also like these sconces and pendant lights. Vanity is white (see photo - will have different top & fixtures). Wall color will be "misty" by SW. House has a coastal vibe to it.

Can I mix these sconces / pendants with that mirror? I reallt like the pendants but i am worried that they might make the already narrow room look even smaller. Which light would you choose and why? What metals should I consider for the vanity faucet?

Mirror we purchased and I love

Vanity Style (its a 48” single for this room, no top)
