Is the ofuro free standing?
Or is it built into a ledge?
Since it has a slanted edge, do you see it from outside?
We had problems explaining the image to the client so we resorted to sketchup and everything was easy!
It is drafted quite roughly, but if you want you can download the model below from the sketchup warehouse.
We also have another couple of models in the warehouse. Search with “bartok” as keyword, you should find them.
