Right, but the material simply isn’t functional. Carpet will get damp and moldy, and wood floors will get wet and very quickly deteriorate. That is why we use materials like marble in bathrooms.
I agree with the other posters. We had assumed that you were looking for feedback and critique since you were posting your work on the arch viz forum, but it appears that you actually aren’t interested in the advice of other posters. I’ll assume that you’re just here to post some work you threw together and collect compliments.
We would be happy to help and offer advice. Building your lights, while it isn’t your intended goal, will go a long way in helping the audience to visualize the scene.
