Re: Did I completely mess up installing toilet flange on subfloor?
The flange needs to be flush with the surface of the finished floor. Thankfully, there are a few things you can do, the easiest will be to raise up what you've got, if you have the space and slack to do so, otherwise, install a slip fit flange. This type of flange has a rubber gasket on it and slides down inside the existing flange. You shim it to the required height and then screw it down firmly. I just had to install one of these and they work very nicely. Another option is a glue type flange, as long as you have not put a wax ring down first, this would work well.
I suffer from CDO ... Its like OCD, but in alphabetical order, LIKE IT SHOULD BE!!!
