Hi,
Your project piqued my interest. I had done a similar job for a different employer on this website (converting 2d plan to 3d render, reference: @abatista7542), and I think I am going to enjoy designing and modeling this bathroom. I believe I fit your requirements. I have the necessary 3D modeling, rendering, interior design, and exterior design experience, and am adept at using the 3D modeling software SketchUp Pro 2021 and other software necessary for modeling and rendering interiors, buildings, furniture, and exteriors. Please check my portfolio on my Freelancer profile page in order to get familiar with my work and see if I truly fit your requirements. The description you provided is more than enough to make me want to work on this project.
Hope that we can arrange a deal, so I can start the job, and help you achieve your vision, with, of course, the help of your supervision and mutual communication. Contact me and provide me with more necessary details, please, if you are interested. Have a nice day...
