I like to have same or similar built-in cabinetry throughout the house and that includes flooring whether it is wood or tile.

I’m thinking about Anonymous or Gauntlet Gray by SW

I would look for a wood vanity in the lightest shade in the floor tile. Your other elements are nice and warm.

Don't do wood-look tile next to real wood. It never looks right.

Are you sure you want your shower walls to look like dirty old chipped stone?

no need to show the other rooms. a bathroom can stand alone from everything else.

off the bat, it's rather dark. and busy.

Once those shower walls are up, that pattern and color variations will dominate the sapce. then you add in the pebble tile (is it real or a porcelain?) AND the wood - look plank tile. Also very busy looking. The vanity looks rustic, but the gray green hue doesn't really work w/the warm tones in the brown tile. maybe it's the lighting in the store that is throwing it off?

I would do a different floor tile in this bathroom (not a wood look). maybe a large hex tile in one of the neutral shades

or a larger tile in this limestone shade.

or, this charcoal hex would work. pair it w/this wood tone and a simple white quartz.

or this natural oak vanity color

I like this tile too. Tilebar Cavatine Bronze. with a warmer wood stain and black and gold
