I don't think that there is any need to use identical colors in baths serving different rooms or parts of the house. I do think that it's preferable for the bath colors (and to some extent style) to be compatible with the room or space that the room can be seen from, but it seems very unlikely that it would be possible to see the interior of one bathroom from the interior of another. What I'm saying is that a feeling of natural, rather than jarring, transition is likely a good thing, but a blue vanity, for example, is not startling in the way that an all-red bathroom (including walls) would be.

I like this article for inspiration for small living areas: https://www.bhg.com/decorating/small-spaces/strategies/living-room-ideas/?slide=slide_396850f0-930d-426a-b58e-6875e8648656#slide_396850f0-930d-426a-b58e-6875e8648656 Things I’d edit or remove: Put the floor lamp in-between the couches. It seems very dark over there and the height would look nice. Put the trunk where the lamp is now. It’s very crowded by your entry. Can toys go in the trunk? If not, I’d get a tall basket for them, it could go behind the lamp in between the couches. A decorative cover on the coffee table, such as a small throw rug, a woven place mat, folded runner, etc. I have a woven throw rug on mine, with a low basket on it for books, remote, etc. (To clarify: not cover the top completely, just part of it. A layered look and bring in color, with some wood still showing). As mentioned, colorful pillows and fix the curtains. I‘d get rid of the entry table and mirror. I’d put a small (but decorative) shoe rack there, and art on the wall. Clear the floor of small clutter. https://www.target.com/p/honey-can-do-rustic-z-frame-shoe-rack-brown/-/A-54579519?ref=tgt_adv_XS000000&AFID=google_pla_df&fndsrc=tgtao&CPNG=PLA_Storage%2BOrganization%2BShopping&adgroup=SC_Storage%2BOrganization&LID=700000001170770pgs&network=g&device=c&location=9027244&gclid=Cj0KCQiAs67yBRC7ARIsAF49CdWVoHC24mJDvW_lro74vvGrKJUioBfHXmJ_1IdOz0hLRlAvIxszB_gaAm6TEALw_wcB&gclsrc=aw.ds I‘d try moving the shelf unit just a few inches towards the dining room, and putting your cute doggie’s bed where the toys are now. A piece of art on the wall space beside the TV. On the TV console, a bit of very low decor ... wood tray, for example. Google ‘tv console decor’ for lots of inspiration. I remember about toys when my DD was little, but I’d definitely try to edit those down, if at all possible. Rotate what’s in their bedroom and living room. I’d try to keep them in just one area, not every corner. But I do remember that struggle, believe me! :D Keep us updated on what you decide! :)

Agree with lynartist get someone knowledgeable in to look at the walls. Shifting the color used makes a huge difference. I would not have the walls smoothed or made shiny. But there are all sorts of ways to approach this and end up with a great looking home. Consider moving the functions of the two spaces. A modern dining area with a fireplace, even such an ornate one, could be spectacular and marry well with a more intimate USED space for conversations, drinks, and even just solo book readin'! Making the switch would also de-emphasize the fireplace and allow it to look its very best. A bit of a paradox but look at many old European houses and you'll see it again and again. My other preference would be to have a wood refinisher take down the shine on the floor. Congratulations and I hope you let us know how this progresses.

Thank you for the suggestions everyone-- this is my first time posting on this site. I appreciate the feedback. I didn't post the room because we currently live in an apartment and we don't plan to be here much longer, but I can definitely repost when I get home if that will help! As for the 60% rule suggestion, I am a total newbie and I truly do not know what would look best. Gray might be too sterile, white might be too clinical, and red may be too bold. There is a sage green in the rug that I think is pretty, but obviously none of my other furniture is that color. I feel like we have bungled this badly already.
