I think that tile will look great! If you want to avoid feeling dark, then make sure the walls are a light color. That matters more than the floor.

I have small bathrooms and both have dark tile floors. I think it grounds them and makes lighter walls more expansive

As a matter of fact, we just had tile laid in a smallish bathroom that looks similar to yours. On the floor, we used a mid-gray tone 12x24 tile laid perpendicular to the tub - so the opposite of what you show in last photo. We also have a dark cabinet, light wall tile. It's a great look and the tile laid perpendicular to the tub actually helps make the room look larger.

I think what you show there will be great but I'd lay the tile perpendicular to the tub.

Thanks for the feedback so far.

Ck-do you have an pics?

We are just finishing up our 5 x 9 bathroom, using a grey floor tile It is somewhat dark, but we used a porcelain marble tile around the tub, white cabinets and a very light blue wall paint. The white and light blue brighten up the room enough, I think.

I just ran upstairs to take this photo for you. We have a ways to go yet! Hope it helps.

Ck do you mind sharing the specifics for your wall tile? Love it!

We did dark floor tile in an even smaller full bath and it looks smashing! :)
