I was planning a remodeling of my bathroom in partnership with a fine-woodworker.
These are the renders I made as reference for what I envisaged.
I started by doing a photogrammetric survey of the whole room, then imported it as a scale reference and started to remodel everything.
It was much easier to try things in 3D to visualize what I wanted. I used actual models from hardware vendors to be as realistic as possible with the tilework and the plumbing.
