Now that I have made a vast fortune from my patented premium dog biscuits, I can afford to build the luxury mansion of my dreams.
I thought my design requirement was very clear: The water for the walk-through shower can be turned ON and OFF from both ends of the room.
The plumber doesn't understand so I have drawn him a plan. I had a few attempts before I got it right!
Which is the correct drawing?
The problem was suggested by Leslie Green
