Which bathroom planner program can you recommend?

There are many programs online for planning bathrooms. I have tried several, but none has really convinced me yet. Which program is your favorite?

Pencil and mm paper. I mean that seriously.

But with good programs, one can quite easily visualize how something appears spatially. Some people have trouble with that, and I don't mean it in a bad way, I am one of them. Also advantageous is simulated light incidence through the windows in the bathroom.
