I agree that the front is removable and that feature is used when they replace the floors, I simply don't think it is that elegant of a solution. They still put brick and mortar in place above the cast iron arch insert which needs to be removed. It also leaves a large portion of the dome unsupported which is not only a risk to the oven, but a risk to the guy sticking his head in there. Don't get me wrong, it works and has worked for much longer then I have been on this earth, but it is not elegant. My ideal is a 5 piece floor that can fit through the door, but we can't even get low conductivity brick in tile sizes here let alone the shapes we want, so you can throw ideal out the window.
