My friend has a toilet with a basin in the same room.
I noticed that he had 2 vertical wooden beams on opposite sides of the wall. Across the top of the 2 beams ran a string.
Does this make the toilet into 2 seperate areas so that it is not considered that one is doing wasser in the same reshus.
How does this work and what are the halachik measurements for making such a seperate reshus.
This is the idea of having the beams: to form a halachic partition between the toilet area and the sink area. This is important for those who are careful not to wash hands in the toilet area.
For details on this matter, see here.
