Where in the home is the bar located? How much are you looking to spend?

It is between our sun room which we use as a family room and a more formal living room. We want to make an investment since we walk through it everyday, but not the cost of a new kitchen :)

Okay, here are the two issues I see with the bar. It's cluttered and it's monochromatic. Those are fairly easy to fix luckily.

Keep the bar top wood, but consider painting the back. It can be any color, white to match the trim or a fun color to add to the bar vibe. I also suggest painting the room, with only those two small windows the dark green is a little too dark. Maybe also swap out the barstools for something more updated.

Then declutter some. I'd lose the corner shelf and the wine rack. Try to clear some of the stuff off the top and move it under the bar if possible.

(Also, lower the mirror above the console. It seems a little too high)

Totally agree with the clutter and the mirror-it’s hiding some holes for now lol.
So you think keep the bar wood and paint bottom of it? Or keep entire bar wood as is.
Thoughts on a veneer stone wall with all of the shelves out, replaced with a couple floating shelves.

Paint bottom black to match other piece in the room. New bar stools and take out that flip top, not needed and adds unnecessary clutter. It's a home bar, you don't need to cordon it off.

Put some big art on the adjacent blank wall, to compete visually and draw the eye away from the wall with all the glasses on it. Declutter as much as you can.
