You can have a glass guy apply a cut mirrored strip plain or beveled to the gap.

^ agree, there are also mirror framing kits online

Going to see where I can find kit. Thanks again

This company sells mirror framing kits and has been around for a long time. I have never used them myself, but if you do a search on the forums you can probably find reviews from people who have used them.

In taking a second look at this room I have to wonder what's going on with your lighting?

If this is a bathroom, you don't have nearly enough light in this room. It's DARK!

Maybe you should use that space above the mirror to run electrical and get some quality light in the room.

I removed the track lights figuring ac way to shoved the mirror gap problem

Well, now you have two issues:

1. Covering the gap
2. Getting enough light

Fortunately, there are LED strip lights available that will provide enough light & not increase the heat load in the room.

Keeping my track lights

If you can't find mirror trim... maybe you could find tile edge pieces that match. Or get a tile guy to trim up some pieces of the wall tile to fit. Or you could use wood trim. Wood would be easier to trim to fit the space.

I know you want to keep your track lights. But consider swapping those gold/bronze ones out for something that matches or compliments your hanging light better. That light is very pretty, and the old track lights aren't going to look great there by comparison.

And I know it's not part of the question... but I wanted to say I really like the walls in your shower.

Thank you
