looks totally fine to me.

maybe remove the child step for showings...

I would lighten and brighten the powder room. Paint the walls a off white and the cabinet white like the trim. A clean looking bathroom sells. At least change the light over the sink globes. Take down the towel bar and shelf over the toilet. The towel bar doesn't belong there. The shelf is to small for the area. There could be a towel ring on the wall next to the sink. If there is room, you could hang the shelf that is presently over the toilet on the wall above the towel ring. Hang a black framed (or what ever color you counter is) picture over the toilet or leave it empty. Replace the two flowered pictures. They seem a little old fashion looking. Something with black and white in them. No fake flowers please. Good luck on the sale of your house.

Contemporary light fixture and round or square mirror. Agree that you should remove rod and shelf, get an over sized piece of art work that goes on wall opposite the door for wow factor as you are passing the room, put hand towel ring on doorway wall above vanity counter top. You are done.
