I uploaded 4 options for the bathroom layout, included in all of them a bathtub. After working on the plans, I realized that it is quite possible to fit everything inside, in the best functional way. I would please you to spend some time reviewing them, and inform me as soon as possible, which option satisfies you the most, in order to work further in the 3d model, the style details and materials. I'm planning to include further options without the bathtub, in case you decide that it is something you don't really need.
Waiting for your response and corrections!
