Can I Install Laminate Flooring Under A Bathroom Toilet And Sink?

You’re finally doing that new bathroom renovation! Awesome! You’ve decided on the laminate flooring, the perfect pedestal sink, and a brand new toilet. But you know that laminate flooring isn’t waterproof… so, do you install the flooring under the bathroom toilet and sink, or do you cut around it?

Start With The Flooring

If you’re installing a new floor, sink, and toilet, you should install the laminate flooring first so it’s under the sink and cabinetry. Because laminate flooring floats above the sub-floor on top of underlayment, it will expand and contract slightly with the temperature and humidity of the room. This makes it impossible for any caulking around the base of the sink and toilet to hold. If you were to install the toilet and sink first, the caulking could crack due to the expansion and contraction, making the installation look sloppy. By installing the flooring first, you will also be able to more easily switch up cabinetry or fixtures, without having gaps in the flooring.

How Do I Install The Flooring Properly?

Precision cutting is key in this type of installation. Cut the flooring around the drains fairly close to the hole. When you install the toilet, screw it down snugly, but not overly tight. If you’re installing a pedestal sink, while it’s heavy, the floor should still be able to expand and contract properly. The most important thing is not to push the baseboard too tight to the floor, and to leave the proper expansion gap, when you install the flooring and molding. This is what allows the floor to expand and contract with changes in temperature and humidity. If you’re worried about water spilling, you can add a waterproof glue to the locking system joints while installing. This will help create a more water-tight seal between planks, which is where the floor will be the most prone to water damage.
