Nice update you done there def4d
And i have to say that David is correct about your tiling, it has a bad tiling in itself making it look weird. You should correct that too.
Bathroom tiles are quite reflective, maybe you add that in time for your final rendering i don't know. But it would probably look good..
Then there's that not-so-nice looking mirror, sharp edges and all that. I vote for a change of that one, a new better more tasty design of it using softer smoother corners, maybe not even rectangular at all
I still got a issue with the sink and the bowls there, the wooden stand they're on isn't just right. It's too sharp and too big. Like someone just took a piece of wood and placed it there without working anything on it.
The carpet on the floor not quite alright as Hervé said, try something else there..
One thing.. i cannot see any sort of piping anywhere in this bathroom, is it all built into the walls or how do you transport the water to and from the different locations in the bathroom ?
The soap close to the mirror there looks like it's glowing, better drop down on the SSS values a bit more.
Maybe you could also boost the mirrorlights intensity a bit more, and add some sort of lightfixture in the ceiling. A bathroom should be well lit to avoid something called "shadow traps".
I think that's all for now
