No chandeliers will give off enough light for say, a guest to fix their makeup, etc. IMO tiny chandeliers are only an extra cosmetic feature in addition to real lighting.

Thanks, and good to know! is this one considered a tiny chandelier?

It's 21' diameter-no, it's not tiny

even 18 inches, I wouldn't call tiny. Small, yes

15,,tiny. For a chandelier I mean

what's the room's length and width?

the room is 44 inches wide x 69 inches long

I think you can have a pendant that's 10 inches in diameter

whether it'll give enough light-depends on how strong lamp, in terms of wattage, it can take, and what design/material it will be..say non-clear glass will give you nicer diffused light, than going open bulb, or metal that will make the light more directed

if you're completely rewiring..for example a pendant goes in the middle of the ceiling..then if you can, install a wall light /sconce on the wall where the switch is..you''l need to check with an electrician whether possible..I'm just talking about pleasing proportions and sight lines currently. No idea whether doable in your room. I remember being very surprized myself when I learnt the light cannot just magically hang in the space I want it to be, but has to connect to the box that has to be attached to a stud that has to be in such and such distance from the corner stud etc-but you're probably smarter than me (even just because it's hard to find somebody dumber than me in everything concerning electricity).

Or. You can try and do pendant where you currently have the opening in the ceiling..but you might need to go with a smaller pendant.

Then the sconce goes on the left to the future mirror.

Obviously they sould complement each other. Won't be very easy. But would be an interesting challenge

Or. You can find a very interesting light that's flush mount to the wall(celing)..and install it over the mirror...you'll probably have space because the ceiling's high. Many of such (often vintage, or vintage-inspired) lights are free-shaped..they imitate branches etc..and they usually have several light bulbs, so you'll have more light and maybe better distributed. But you need to love the idea.. and for it to go with character of your bathroom

Or you go with simplest thing ever-do an over the vanity light.

You can think of wallpapering the ceiling, or painting it different color, to show it off more.

When hunting lights-don't forget to check out Etsy, eBay, Chairish, besides regular stores. You might not save time, but you'll save money, for better quality, and might give you ideas and show things that weren't even on your radar before.

some shops on Etsy-the ones that actually make lights- customize their light fixtures per your request. You can ask for a certain size, etc. The customer service is usually very good. Sellers do care a lot about their repuration and feedback.,

oh important question..will you center the future sink?

If yes-then couple options out of wat I though about are lessrelevant, while maybe another option can be..like two sconses on the sides..but..again, should be checked whether possible in the narrow space. I know I couldn't do it in mine as much as I wished to. The sconce itself can be narrow, it's the matter of wiring.

AprilNeverEnds, thanks for your thoughts, I really appreciate it.
