Pergo can be installed in a bathroom, but it is not recommended. If water were to seep into the cracks of between the boards, or underneath the boards, it will cause them to swell. If you insist in the installation, be sure to seal the seams with glue.
It is possible to use laminate flooring such as Pergo in your bathroom. However, you need to be cautious about water getting through the joins between boards and soaking into the flooring material. The composite material under the laminate swells if it soaks up water. Be sure to mop up spills or drops immediately and you will be fine.
By "pergo" one assumes that laminated wood flooring is meant. The answer is yes. Some assumptions: the bathroom will be used and maintained carefully. The trick is to keep water from infiltrating the top, finished surface and getting through to the underlayment. Wherever that might occur, trim the floor to keep water out. Follow the manufacturer's instructions.
Yes. It is highly water resistant so it can be used in a bathroom or a kitchen. However you need to seal the expansion spaces with some type of mildew resistant silicone. Some say you should seal the joints with glue. Make sure you remove any standing water right away as this will warp or ruin your flooring.
You can put pergo in the bathroom, but you don't want. It traps moisture, both getting out of the tub or shower, and around the toilet. It's not worth the money to put it down and be dissappointed within a year that you made a mistake. Tile is the safest and easier to keep clean.
I think Pergo is not suitable for bathrooms. The main reason is that, it is not water resistant. If we use it in the bathroom, it does not exist for a long. It is more suitable for bedrooms, sitting rooms, dining room, etc... The use of pergo will give more attraction to these rooms.
