This bathroom is great because it such a blank canvas. It is nice to see these types of spaces without anything in them yet because it gives us the chance to step back and ask ourselves what we would put in them. For this bathroom here are the things I would add. I would put some plants around the tub, and maybe put in a nice little stand in the corner for toiletries such as soap and what-not. Then I would put some art up in the corner above the toiletry stand. This way we could have utility as well as a nice aesthetic variance.
