Thank you for your suggestions and ideas! I love some of the more daring/colourful ideas, but I don't think I'm, personally, bold enough to go with such a contemporary look. I'm going to stick to a traditional/modern style and use large (4" x 8") white subway tiles and dark grey grout. I'm thinking of using a dark grey paint around the kitchen walls and then a lighter shade around the rest of the room, with maybe the dark grey on the wall behind the TV too. Will be a few more weeks before that's all done, but I'll post a picture when I eventually get there. Thanks again!

We are thinking maybe a terazzo tile of some sort- one that integrates the red, black and white, and beige (from the wood floors adjacent). This could pull it all together, for one cohesive room! See images.

Hi, I have a rich walnut gloss floor and it looks stunning with white & grey and brings a warmth to the room (You can get away with a darker walnut as well but mine is a mix of dark and more yellow tones)

What color of paint for walls in bathroom that had gray tiles
