The toilet ended up sitting on the front walk for a few days and the porch became a dumping ground for the debris.
Our dog, Pitoune, immediately noticed the space left over, thinking to herself, "hey, wasn't there a bathtub here yesterday? And check out that floor! Tiny ugly pebbles glued to plywood and a complete bitch to remove (click on this or any picture to enlarge for a clearer view). An hour with a sledge hammer and and an ice scraper and it was gone.
In the end, we left nothing but the bare bones so we could begin replacing the plumbing and rewiring the electrical lines. Now that the demolition is almost done, we can focus on re-building. This will be the first new room in the house that will not include the smell of anything old. Believe it or not, we have grand visions for this space. The ability to use an indoor bathroom again tops the list.
