How to Install Floating Floors in a Bathroom

Floating floors are designed to snap together in courses, covering the whole floor without being nailed or glued down. The trim around the edges of the room holds the floor in place. If you want to use a floating floor in a bathroom, you'll have a few extra issues to deal with. Standard kits are laminated wood, and aren't necessarily moisture-resistant, so find a kit that specifies that it is. Also, get a good jigsaw, as you'll need to cut around the toilet drain and the curve of the tub.

Step 1

Remove all trim and fixtures from the floor.  Pull the toilet, so there's just a drain hole there. Get the floor clean and dry. 

Step 2

Roll foam underlayment alongside the wall where you want to start.  Cut the underlayment to size with a utility knife. Roll out more underlayment, butting the sides of each course against each other and tape the seams with duct tape.  Cover the whole floor.

Step 3

Lay floor planks along the starting wall, with the grooved sides facing the wall.  Snap the ends together. Put shims between the boards and the wall, so the boards are held out 1/4 inch from the wall.  (This will provide room for the floor to expand) Cut the end of the last board on a miter saw to get it to fit.

Step 4

Lay the next courses of boards alongside the first, snapping them together along their sides and working your way across the floor.  Use your jigsaw to cut boards around the toilet drain and around the curve of the base of the tub. Lay the whole whole floor, leaving the 1/4 inch gaps along the walls on all sides, and along the tub. 

Step 5

Set tub trim along the base of the tub to cover the edge of the flooring there.  Secure the tub trim with silicone caulk.

Step 6

Install floor trim throughout the rest of the room, using your miter saw and trim nailer to cut and secure it so it covers up the gaps by the walls. 

Warning

  • Wear eye protection when you cut the planks.
