any of these mirrors would be fine. just measure your space and see what works. (get some blue tape and make a mirror w/it)

I'd also turn those fixtures down. light is supposed to shine down, not way up on the ceiling)

Thanks, Beth! I like your idea with white mirror frames. Would you think wood frames would be too much with the floor? Would this lamp be too much, or

I think you could do a thin wood frame. do a medium tone to match the floor.

as for the light, first, you need to make sure it is damp rated. (I don't think that one is)

and code for most tubs :

The National Electric Code (NEC) from 2011 requires that any part of a light fixture, including crystals dangling from chandeliers, must be a minimum of 8 feet above the highest portion of a tub's walls. This no-chandelier zone extends out horizontally 3 feet around the tub rim.

I would have enough clearance, the lamp is where the bulb is currently hanging. but you are right, that one isn't damp satisfied. any recommendation?

Love the idea of a pivot mirror in your space!

Your bathroom has a subtle glam and yet sophisticated feel. I think these add to the traditional sophisticated vibe you've started. I would play off the greys and silvers in the space with a more polished look of a polished chrome finish.

Then, finish it off with something like this:
