I found this a bit difficult to rate, as it's a very "left field" image. On balance, I think it's a better idea than it is a photograph - the composition feels random and the lighting is average. However, there's nothing else like it in the challenge, and that's good. And it is visually shocking.
Yeay! I think it's great. You dare to use the subtle object to present the bathroom. I just love the location. But you may want to take some more time, if not too smelly, to play in there to make the fine balance what you want to say and the challenge.
The purple top is so minute in this picture that it barely shows the contrast. Perphaps just a shot of the sink with it in the upper left corner would have been more beneficial.
