Wood flooring isn't usually recommended for bathrooms, since the moisture in the air of the bathroom can cause the wood to warp or rot over time. However, a wood laminate floor will stand up to moisture better. Wood laminate floors, which are coated in a form of plastic, usually are sold as floating floors, meaning they aren't glued or nailed down, but just sit on top of the subfloor. Start with a solid, flat flooring surface.
Remove the toilet by turning off the water supply line behind it, loosening the water line from the tank with your wrench, then loosening the floor bolts holding the toilet base down to the floor. Carry the toilet out of the room.
Remove the sink if it's a pedestal that can be easily taken out. If it's a vanity sink, leave it in place.
Remove the trim from the edges of the floor with your hammer and prybar. Keep it intact as you take it off. Set it aside.
Spread out plastic underlayment along the side of the room where you want to begin. Cutting it with a razor knife to fit.
Lay a floating floor board alongside the wall at one end of the floor. Put spacers between the board and the wall to create a gap there, which will give the flooring somewhere to expand with climate changes.
Set a second board off the end of the first one, pressing the two boards together end to end until they lock.
Repeat the process, setting floorboards end to end off each other and along the wall. Use a mitre saw to cut the last board, as needed.
Lay more courses of boards, connecting them by their long sides and working your way across the floor course by course. Cut around the sink vanity (if necessary) with your jigsaw. Position the boards so the ends don't line up between courses. Lay more plastic underlayment as necessary.
Cut the boards around the toilet drain with a jigsaw as needed when you get to that part of the floor. Cut the boards so they sit 1/2 inch or so around the outside of the perimeter of the drain in the floor. The cuts don't have to be precise, as the toilet base will cover them.
Reinstall the toilet over the flooring. Lay a bead of caulk around the toilet base, sealing it to the floor. Reinstall the floor trim, using your trim nails and hammer, to hide the spaces around the perimeter.
