With little natural light, I'd go one lighter with BM Blue Veil It always looks darker on the wall.

Post the pic in a comment now and wait until it is no longer garyed before submitting.

Ironic actually, I have the same floor tiles in my guest shower floor.

I painted the walls Behr Day Spa. (Home Depot) I have a white and navy marble on the main floor and white subway tile half way up the walls.

One window, the Behr Day Spa shows just enough blue to make it feel spa like.

I would keep the walls white and paint the cabinet for a custom look. Pick one of the darker blues from the tiles.

I will suggest BM Paper White because I used it in my laundry room in my previous house. It looks different in different light, so you would have to try it in yours, but it is a pale bluish gray that might work for you. It looks more interesting on a wall than it does on a paint chip.

Not a fan of either, especially with a north facing window.

Suggest a less grey undertone in a deeper shade and bathroom will pop.

Great suggestions everyone! Thank you!

Maureen - I love that darker blue idea! Your post and pictures are very helpful. I had the painter put up two samples yesterday . Both light greys with a blue undertone. If they don't work, I am going to look the direction that you suggest.

Kandrew - I have a large sample of paper white so I'll take it to the house today to see how it looks.

Lisedv - The dark vanity looks great but we just had the one that is there custom painted so it will stay white. I was thinking bright and clean when I chose the white vanity. I do like your suggestion, however.

Lyn - It's a fun tile and thank you for sharing.

I will keep you all posted! Thanks again!
