It’s already very “updated” current gray fad in style. Focus on something else and revisit in 6 months. You may want to rip it all out. Or you may want to paint it a deep purple and add more and better lighting. But you’ll have other things to spend your money on for at least 6 months.

If you must keep the tiles for now here’s some pics that might help. Looks like they painted the walls off-white and lavender. Purple accents to pick up on the tiles (ie towels)

Paint it white for now. Or the same grey as the tile (so it doesn't stand out that much), but 'regular' matte.

Two very good light grays that go with everything - almost a tinted white - are Sherwin Williams - On the Rocks, or Crushed Ice - it will give your bather a lighter, more contemporary feel, and really highlight those mosaic tiles - which are actually very nice :) You should also clean and seal the grout as good maintenance :)

@CK Hoffman Design I love those two grays. Thank you. Do you have any suggestions for a SW colour to paint the cabinet? The paint is chipping and I need to repaint it. I was also thinking of painting the grout on the floor a lighter colour too to match the tile.
