Need views of the walls in question from a bit further back -- i.e., the tub wall (is part not tiled?) and toilet wall.

I presume the ledge will have things like shampoo and maybe a nice loofa?

I think the shelf by your tub is crying our for a big fern. They thrive in bathrooms and add a lot of color and texture. Keep an eye our for something interesting for the wall- maybe something graphic with black and white and a small shot of green. Or a cool turtle print might be nice - I know turtles can be a bathroom cliche, but with your color scheme, it seems like the right one would be perfection.

If you aren't putting doors on the cabinets, then put some rolled up towels under the sinks.

You painted the hip new color of the year, "Green". Succulents and a patterned or pretty rug in front of sinks. Glass shelving or towel racks over tub area. Inspirations below. Pretty Glass jars with cotton balls and q tips and simple pretty soap dispenser. Tortoise shell tissue holder for glam.

If no doors, those sink traps should be chrome.

Something you don't mind having covered in fecal bacteria or something you can clean easily.
