fitting heavy items such as wc or pedestal basin onto of LVT

I have been asked to lay LG hausy advance LVT flooring as part of a bathroom refit. Instructions say not to put heavy items such as wc or pedestal basin on top. They say to cut around with expansion gap. Does this depend on room size. If it is a small room surely expansion isn't going to that great. Cutting around doesn't seem viable to me.

 

Wouldn’t worry about it, just leave expansion around screw holes for the toilet with a hole cutter
