I am trying to replace a toilet which is on top of a block of wood. Before I uninstalled the old toilet, I thought that I would be able to remove the block of wood but now that I have removed the old toilet, I am not able to remove the wood block. After further inspection, I noticed that when I try to lift the wood block, the supply line moves which leads me to believe that the wood block is affixed to the plumbing some how. I have tried unscrewing the flange and also the two screws at the front of the block and it still isn't coming free. On top of this, the new toilet doesn't fit on the wood block so I am now forced to find a way to remove it.
What do I need to do to remove this block and install the new toilet?
