Some types of laminate flooring are now suitable for bathroom use, as they have been developed to withstand the high levels of moisture in the atmosphere.  Before you buy, check that the laminate floor you want is suitable for bathrooms.  If you're installing a new floor as part of your bathroom remodeling, it can make it easier to lay the floor before installing fixtures such as a pedestal sink or vanity cabinet.  Another tip is to remove the skirting board and lay the floor right up to the wall, before replacing the skirting board.  This can help give a neater finish.  Laminate flooring can be laid onto dry concrete, chipboard, hardboard or plywood.

Laminate flooring comes in boards, generally about 3ft long, or longer.  The idea is to lay the boards in rows as you work across the room.  Rows are staggered, so the joints don't line up.  This not only looks good, but also adds strength to the floor.  It's best to avoid cutting laminate flooring where you can, and start with the longest bits first.  Unlike with tiles, you can start at the edge of the room, as if your walls aren't square it won't show up so much with laminate flooring.

The first step is to lay out your underlay over the sub-floor.  Underlay comes in rolls and is easy to roll out.  Butt up the joining edges and don't leave any overlap anywhere.  You can cut it with scissors or a craft knife.  Then put your first piece of laminate against the skirting board where you intend to start.  The groove should be facing the skirting board, and the tongue side should face into the room.  Use spacing blocks to leave a gap between the skirting and the laminate board.

With the second row, cut out a shorter length of board to create a brick bond pattern, so the joins in each row don't line up.  Put wood glue or similar adhesive along the tongue of your first row and line up the groove on the cut board with the tongue of the first row.  Tap it into position using a hammer and knocking block.  Make sure you clean any excess adhesive off the laminate surface before it dries.  Carry on across the row, using a jimmy at the end of the rows to knock the boards into place.

When you've finishing laying the floor, it's time to remove the spacing blocks from around the edges and stick quadrant moulding around the edges.  This will probably come with self-adhesive tape to fix it to the skirting junction.  You will have to mitre the ends to fit them into the corners.
