Can I fix a toilet pan directly to the floating floor?
It is not advisable to fix any object through a floating floor as if this is done pinching of the floor at the given point may occur. This may result in the flooring moving in one area and may cause opening up in others. If the toilet pan is to be fixed through the floor it is advisable to fully bond the floor to the sub floor, this should then be fine. Alternatively the floor can be scribed around the toilet pan very carefully following the contours of the pan with a compass and pencil. Under cut the boards at 45 deg and seal around the top of the board and the WC pan with a good quality silicone.
