You might look into corner mirrors and they look great in vintage bathrooms. There’s lots of styles But they fasten to a side wall but can move back to wall or to float in front of you at sink etc… You might get a white frame ledge ir get one painted wall color, the length if window and hang below window for your stuff ledge… I love your lights but I think they compete/ invite comparison to sink and make sink even tinier by comparison since lights shouldn’t be bigger than the sink. You coukd look for similar ones but that are much narrower, or go for a different shape plus smaller fixture, or go so different like Tiffany stained glass it won’t compare. But I’m unsure how those would be for lighting… Or dangling ones, however not as long as shown here because they’d interfere with the flexible mirror… but these are things to think about. Cute room. Also one photo of a room limits us, there might have been other ideas we could come up with… More on reddit.com

Whatever you do, put all the lights in appropriate dimmer switches. My electrician thought I was dumb for insisting but MY GOD how nice it is to use the bathroom first thing in the morning or in the middle of the night and not be blasted instantly awake. Dimmers. Seriously. More on reddit.com

Because the counters and side walls are plenty full already, I say leave it as is. More on reddit.com

I think it partially depends on what works for your bathroom layout, but when I remodeled I opted for a hanging cabinet/shelf instead, like this and just used a regular wall-mounted mirror above the sink. But you can also get recessed mirrors that don't really look like medicine cabinets per se but still swing out with some shallow storage. IMO, the big boxy obvious medicine cabinets look pretty dated. More on reddit.com
