Great idea, Go for it

The distance between the two door wood frames would need to be known. Your budget would also be of help

It's 59" between the two door frames.

do you have a budget in mind and what is the width so there is no obstruction for walking that you feel is best for width if the space isn't wide open?

I'd select something about 40" in width so you have just shy of 10" on each side so it doesn't look too large.

A vertical mirror will work best since you have the obstruction of the thermostat and switch plate. Keep the frame minimal and simple so you have a nice mirror and nothing ornate and busy. A thin metal in what you appear to favor in a darker metal.

You should select your table then your mirror after so you know the size in width better. I would stick to about 40". A round mirror most likely will not work, but again I'd get the table them post a photo.

40" as I said or there about would be best.... however, know the width of the table top from the wall out that fits the space best.

You can google, "40" entry tables" and you'll find many.

I don't think I'd want that style again since we just got a new dining room set.

Antique style or your style dresser, Mirror for sure. Maybe a lamp.....

Thanks, I'll start looking at them.

Very pretty!!! Thanks.

Where did you find that?

Was looking for table with same look as your DR chairs....

Got my dining room set at Carson's.

So, if it seems there's not 'much going on' in that whole area - maybe you'd like, maybe not, a striking shape or color there....
