Thanks,

Yes, the handle is kinda diminutive when rendered in a room scene.
The advantage of rendering in a real-world inspired scene space is that you can get a better "eye" on how things like inventions and custom shapes would actually "feel".
(in a manner of speaking).

I created the toilet, and bathroom to size. And by doing that I soon realized when rendering that the toiled look more "grand" when modeled by itself with dramatic lighting.
Here, it kinda just looks like a humble toilet with a cool handle.

Because the room I created is not really a large open space, the resulting renders will have to be done as separate piece shots, focusing on the highlights, like the handle.
When you think about it, most of those nice, modern living-space renders architects like to show off, if brought to reality, would have to lead you to believe that only billionaires commissioned these pieces! Where someone's "bathroom from the future" is actually larger than my whole house!

I say a real challenge is designing for spaces that real humans live in. Where most may have rooms that might not exceed 12' in any direction.
