Most installers won't move the toilets, instead opting to install the floor and cut it according to the size and shape of the toilet. However, it is recommended that you remove the toilet, install the floor, and then replace the toilet. This is because installing a new bathroom floor requires precise cutting and a completely smooth and level surface. If you're placing new linoleum in an existing bathroom, chances are that there's already tile or another floor in place.
Because linoleum must be installed on a completely smooth and level surface, the old floor will most likely need to be removed before the linoleum can be laid. Your toilet is installed on top of the existing floor, which is placed right up to the toilet drain pipe. Attempting to remove the existing floor to the edge of the toilet can be difficult, if not impossible, depending on the material being used.When installing the new floor, it is important to cut it around the drains fairly close to the hole. When installing the toilet, screw it tightly, but without tightening it too tight.
If you are going to install a sink with a pedestal, even if it is heavy, the floor should be able to expand and contract properly. Installing the floor first also allows you to more easily change cabinets or accessories without leaving gaps in the floor.It is important not to put too much stationary weight on the floor, as this could end up pinching the floor against the subfloor and making it unable to expand or contract. If you are installing a sink with legs, then the floor will encompass the entire space.
