I need some suggestions for a gray paint for the walls.

It's a long narrow master bathroom (just under 5' wide by 17' long). There will be 4"x16" white subway tile on the walls with Mapei Pearl Gray grout.

The floor tile will be Happy Floors Kaleido 12"x24" tile, stacked, in color Cenere. This tile will continue from the floor through the curbless shower and up the back shower wall. The floor tile grout will be Mapei Timberwolf.

The floating vanity will be white oak and all of the faucets/fixtures will be matte black, including a matte black towel warmer.

There's really not much wall that won't be tiled in the bathroom itself but for the time being, there will be no door to the adjoining master closet, so I figure I'll paint the closet walls the same as the bathroom walls.

It's still very much under construction so there's no worthwhile pictures to share but the closet shelving is being installed Friday, so I have to have the closet walls painted first.

Thanks!
