This is approximately what our downstairs half-bath looked like until last week. I say "approximately" because I took this particular photo in 2007 — 12 years ago. It's a long narrow room resembling a hallway, with a toilet, a small sink, and a radiator in it. We painted it blue all those years ago and hung pictures on the walls.
It's funny, this morning when I went to take a photo of what the little "loo" looks like right now, I pushed the light switch and nothing happened. Almost in protest, the light bulb in the ceiling fixture has burned out. I guess. Or there's some other problem. I hope it's just a coincidence that it has burned out during the plumbing work. I thought we had put a new LED bulb in there, but maybe it's an old incandescent.
I got this photo using my camera's flash. Since significant plumbing work needed to be done to hook the new upstairs fixture into the drainage system, we decided to have a new toilet installed in here too. It'll be a wall-mounted commode (une toilette suspendue or un WC suspendu) — I think "commode" might be a Southern U.S. term for toilet. We figure it will be easier to clean the floor in the WC if the toilet is wall-hung. The old toilet is 16 years old, and right now it's sittingoutside in our front driveway, below the terrace.
In this photo you can see the frame or bracket on which the porcelain toilet will be mounted. The frame will be boxed in using wall board, and there will be a shelf on top of that. Our first plan would have involved running the drain pipe from upstairs down the back wall in one of the corners of this room and having the whole back wall boxed in to hide the pipes, but then the window would have been in a kind of tunnel.
Finally, at the last minute, we decided it would be better to run the big drain pipe down the wall in the main bathroom, which is just on the other side of a partition from the half-bath. (There is no toilet in the main bathroom. That's a French way of arranging the facilities.)
You can see the drain pipe and the way it comes into the room and hooks into the same drain pipe that connects, or will connect, to the new downstairs fixture and to the sewer mains down below.
