A pedestal sink is typically a two piece sink. The bowl sits on a base and until everything becomes tied together, it can be a little wobbly. It’s a good idea to mark the location of each piece.

Set the sink base in the approximate location near the wall and then set the bowl on top of it. It will be a slightly unsteady until you support it with the wall. Use a level and level the bowl front to back and side to side. This is the time to make adjustments to the position of the base and the bowl. When you move the base you will need to adjust the position of the bowl. Once everything is in position it will be fairly stable. Make sure you are happy with the positioning and use a pencil and mark the outline of the base on the floor. Also mark the position of the mounting holes for the bowl. You won’t see the pencil lines for the mounting holes like you would if you marked around the perimeter of the bowl.

Once the position is marked out, you can remove the bowl and base. Use an adhesive product to stick the base to the floor. I like adhesive caulking, but I know people that use silicone. You can also use adhesive between the sink bowl and base, and between the sink bowl and wall. A wet finger will smooth the transition at these points. You will have to secure the sink bowl to the wall through the mounting holes underneath using screws and washers or lag bolts with washers. Just make sure you secure it into lumber.
