What do you furniture and other room accessories look like? Is the floor the same as in the mockups?

Our furniture and accessories are a mix of transitional/mid-century modern. The room is a mess right now in the middle of the remodel so the attached photos are the best examples I could find. And the floors are not exactly the same as the mockup, but it is a yellow oak (visible in one of the below photos) Thank you!

I like the first one better- looks a bit lighter so better with the floor.

Are you keeping the firebox in the current location? Your actual space looks more narrow than the mock up and that will affect how everything looks.

No, that entire wood wall and fireplace have already been removed and the fireplace has been moved further left. The mockup is an actual picture of the space with other images placed on top to get as accurate an idea as possible of the space (though likely still a bit off). That being said, that line from floor to ceiling to the right of the mockup is supposed to be the corner so the space to the right of that is the adjacent wall.

I think you have to decide what look your going for. The first tile although modern the texture being rougher makes it more rustic in appearance. The second tile being more a shiney tile has a more "dressed up" formal feel. Very classy kind of look. I prefer the second but that's my taste. I like clean smooth surfaces that are easy to clean and have a more modern look. Either are good but it's more about what kind of look are you planning for the rest of the room
What kind of furnishings do you like.

I hope you're not planning to do cabinetry in front of a firebox like in that mockup... !

I like the first one, and I;d get the floor refinished in a different stain color. the yellow tone does not work w/either.

this color wood would look nice

Option 1

The rendering looks like the wall is about 15 ft (2 ft left of tiled area, 6 ft of tiles, 7 ft right of tiled area) but your picture looks like the wall is narrower than 15 ft - may just be an optical illusion due to the high ceiling
