My first thought was the tiles that look like slate. Too dark?

But maybe lighten things up. I wouldn't do wood, look of wood, engineered wood, wood look laminate, etc. Tiles like this can be bought in numerous formats pretty cheaply.

I wanted to suggest Retro Renovation. Maybe search "flooring" or"paneling" and see what comes up.

I found this one quickly:

I like the warmth and subtle texture of this flooring.

Or if you wanted to bring in another color, you can also do that in the flooring. This gray makes a nice offset to the wood.

I appreciate all the suggestions! I like the slate look, but do think it will be to dark in this room. I love the linen look in color, and I will search for something similar at a better price point. AnnieDeighnaugh, all three of yours are nice -- I had mentally ruled out grey, thinking it would be too blah, but it looks good! I am going to take some time to go through the site you linked. Thanks, all

This is our kitchen in our lake camp, pretty utilitarian beige vinyl.

Utilitarian is good, woodie2, I'm not looking for the floor to be the star!

Here's your basic "wood overload"! This was the attic conversion of my previous (1940s-era) home, with original knotty pine on the walls and ceiling and original oak flooring. I think you can do wood-on-wood and have it look just fine, so long as the tones complement one another. They don't have to match perfectly, and you can see from the photo of the den (below) that in this room, the paneling and floor definitely don't match.

Since you seem to like the engineered hardwood, I'd keep leaning in that direction if I were you.

Raee - actually the original red formica from the 50's is the star in our kitchen LOL.

When I pulled out the carpeting in place when I bought the house, I found that the floor was a material that looked for all the world like thick, densely compressed paper/cardboard over diagonally laid wood planks on the joists. I replaced that with a sturdier subfloor which has made a difference in the stability and vibrations (nearby trains used to make the room shake).

Coretec has some nice "stone" look vinyl tiles that would not clash with either the knotty pine or the red oak. I plan to use them in my lake home where I have walnut cabinets and knotty pine ceilings. I like the Amalfi Beige or Noce Travertine to match the golden tones in the knotty pine without being too dark.

I have yellowed knotty pine on the walls of my late 40s/early 50s beach cottage with oak flooring. Works for me (primarily because I got a great deal on the oak when I was looking to replace the skanky and probably original early 50s carpet), but I was really intrigued by the possibility of using cork or real linoleum flooring in the room. I think it would have looked great - it was just a bit pricey in my situation. Both are supposed to hold up to pet traffic very well and happen to be more or less era appropriate with a room full of knotty pine.

We have knotty pine den in our 1942 home and it has hardwoods. I have a rug over it too. If I didn't want to use wood I would put down Marmoleum. I think it goes great with the mid century feel of knotty pine and it's a great material.

I found both of these on clearance at Menards; would have to visit several stores to get enough for the room but that is certainly doable at this price. This is a floating vinyl. I brought a sample of the 'mountain slate' home and think it reads pretty neutral and not too dark. What do you all think? I can't take a pic of it against the pine tonight, will try tomorrow.

Hmm the pics aren't showing but if I click on them they pop up.

I think that can work well!

Love all these paneled rooms! Ida, the wood-on-wood is awesome.

We are struggling with what to do with the flooring in this room. Thinking about a lighter travertine. Thoughts?
