Beverly's idea looks very nice. Personally, I would have to remove them. It depends if you like that look.

before you consider removing, i'd drape them in drop cloths, whatever, to get a sense of the actual room size. you might not like having the room be half the size it appears with them. seems it would feel very narrow for the height, which is why they are probably there.

Thank you for your suggestions. We definitely consider removing it at some point ...however, looking for more temporary fix at the moment due to budget constraints ...considering to paint the rest of the walls grey and paint the trims white...would sticking a wall paper and painting it grey (same as the rest of the walls) do the trick?

Have you searched Google for info about painting mirrors? I recall reading that it can be done.

I'd paint the trim. (paint the mirror?? wow. for the cost and work that would need, you could just remove them)

actually the cheapest and easiest would be to remove the wood trim and drywall over the mirrors.

or, embrace them and :

paint the trim white or even black, along w/the other trim, and lighten up the room. change out the 1985 oak blinds for something else as well. remove the ceiling fan and spray it a matte black

you could use decorative window film to cover them. it would be easier than wallpaper.

Or frost them.

If you're wanting to cover them I'd try some sort of removable contact paper or wallpaper. I think just painting the trim white will make a huge difference though.

Painting a mirrored wall is no more work than painting any other wall. Roll on the paint. http://sewmanyways.blogspot.ca/2012/12/tool-time-tuesdaypainting-mirrors.html

If you've ever tried to remove paint from glass, you'll know that it sticks just fine.

Put in some plants, at least the reflections will repeat the foliage.

I agree with painting the molding. I would think the most economical way to change up the look would be to frost them. Trying to keep those clean would be a nightmare!!!

I would paint trim white - hang sheers over the bottom half. Then put a plant shelf above the curtain rod with low maintenance plants. It would give the illusion of bringing in the outside and not visually narrow the room. The high ceilings and narrow dimensions would make this room seem very narrow without the mirrors.

Remove them.

Very dated look.

As stated, paint the surrounding trim white, and remove the mirror over the fireplace - that's one too many mirrors.

Perhaps paper over the mirrors until you are ready to remove them.

Well, it seems like you have two choices ... either remove them or work around them. I can't imagine it would be that much to remove them if you don't like them ... maybe a little bit of drywall work and some paint, none of that type of work is expensive. If you decide to keep them, then I would see if you can remove those paneling pieces (are those just laying on top of the mirror?) If not, then I would paint the paneling pieces and I would hang art over the top of the mirror (with no-damage hanging strips) as if it was an actual wall. Two things I would not do .... paint mirror or wall paper mirror ... that's ridiculous, you're just throwing good money after bad, it would cost more in the long run than just removing them and doing it the correct way plus it would not look good. And just as a side note ... mirrored walls are not dated, they have come back again and like everything else in life, it's all in the presentation.
