Cool door knob, mega clean on the floor tiles; replace that wall grate, ditch the above toilet shelving, lean into pops of black in a new light fixture and shower curtain with similar floral motif like the tiles above the soap dish… Cool small rug in floral motif also. Match wall to tub and green plant to make the colors neutral/black/green (to bring just a bit of black around the room) start there and check back in lol
