Properly laying laminate flooring around a toilet can be difficult due to the need to ensure the laminate is flush against the toilet. In some cases, it is possible to slip laminate under the toilet without removing it. In other cases, intricate cuts need to be made, and the toilet must be lifted so laminate can go underneath it in order to give your floor a finished, cohesive look.

Beginning the Job

If you do not intend to remove the toilet to install laminate, you must work around the obstacle. First, the lamination sheet needs to be cut around the size and shape of the toilet. Use a pencil to mark around the shape of the toilet on your laminate sheet so that you can cut the laminate to account for the curves of the toilet's base. Use a driller to cut the sheets in the proper shape.

Cutting

Leaving 1/4 inch of leeway between the laminate and the toilet allows for expansion. After the laminate sheet has been cut, lay the laminate next to the toilet and install. The 1/4-inch gap that you left should be filled with silicone caulk to strengthen the laminate and to keep moisture away from the laminate sheets.

Removing the Toilet

If you intend to remove the toilet to install your laminate flooring, first turn off the water to the toilet. After lifting the toilet, use a damp cloth to cover the drainage pipe to prevent toxic fumes from coming out. Mark the size and shape of the toilet on a laminate sheet using chalk or pencil. Dry-lay the flooring so that it goes right up the toilet flange. Use a piece of flexi-curve (available at home improvement stores) around the flange to create room to allow the laminate to expand. Apply caulk, and lay out and install the laminate sheets. After the laminate is dry, you can put the toilet back.
