As I started collecting the materials for this project, I realized I would need to find some very specific items. In fact, I remember thinking to myself, "where am I going to find a toilet flange?" Now, the technical term, if you are going to search for one on a home improvement store's website is a "closet flange." As in Water Closet. (I guess that flange was designed by a British guy). My first experience with a PVC closet flange was during my main bathroom remodel. I installed tile, complete with a backerboard, and subsequently raised the floor by one inch. I realized that the toilet would never fit the drain, and it was then that I discovered the closet flange and the cheater spacer kit.
Now, back to the basement, there is a four inch drain pipe protruding from the floor, but I knew it would need a closet flange. And that is not really something you find used. Nor does Lowes or Home Depot give them away. Even Menards wouldn't offer a Black Friday rebate on one. You just have to buy them- for about $10 each. And that is a problem when you are trying to build a free bathroom. In fact, as I wondered where I might find one, I seriously began to doubt if this "free bathroom" crazy idea would be successful.
Then I saw the magic Craigslist ad. A family in Peculiar, Missouri, was moving and getting rid of stuff. Among the spoils- a box of plumbing stuff. I knew I needed plumbing stuff, so I made the drive that night, somehow found the house in the dark, and gratefully received the box of plumbing stuff. And guess what was in it? A PVC closet flange!!!!
