While my machine is rendering on a small bathroom scene :) I´ll give you my personal impression on your bathroom.
Already saw it on your website.
Now, seeing it once again, it has the same effect on me: a bit hard to focus on anything in the scene due to those countless glossy, tiny tiles.
The ceiling could be in darkness, too... not lit. So the view would automatically go more to the centre and that vomiting dude. :)
Technical stuff: the metal sheets look too 2D. Give them a thicker edge.
Mirrors are too clean. The cry for some imperfections. The same for that paper towel box.
Also try less light and contrast on the tiles in the background. They also distract too much from the essential of your story.
I hope you take my impression as constructive feedback and appreciation for your work.
You know... it is always easier to see "flaws" in other peoples´work. :)
