I am coming to the end of a major house renovation involving two baths, kitchen, etc.. all gutted down to the studs. A few months ago I met with my plumber to discuss the layout of the bathroom fixtures. A floor joist was located where the toilet flange was to be installed. He mentioned that it wouldn't be a problem due to the use of an offset flange. Fast forward 4 months later. Everything is closed in, floor is tiled, and toilet was installed today. The problem: the toilet is 3 1/2 inches away from the wall and looks awful. My plumber's response was that the offset moved the rough in by a few inches.
1. Does an offset really move the rough in by that much? I assumed the rough in remained the same regardless of the flange being used.
2. Can I get a larger tank to make up the difference?
3. If I have to get another toilet, do I go to a 10 or a 14 inch rough in?
Final piece of into: The toilet that has been installed is a Kohler memoirs stately design with a 12 inch rough in. According to their specs, it should be around 1/2 inch away from the wall.
Any and all advice would be greatly appreciated.
