WC replacing

ornellab <ornella.battaglini@...>

Hi all,
I need to remove the WC from the floor of my Santorin to replace it with an identical new one. My doubt is this: do the screws holding the WC have any slab or locknut under the floor, so that I could put the new ones without any problem? Or must I disassemble the toilet's floor?
Thnk you for your help.
