I'm moving the washer/dryer to the second floor. I'm installing an enclosed tiled floor with a floor drain to catch any leaks. (It's elevated 5" so that the laundry basket fits under the doors when you swing them open and so you don't have bend over as far).
It was recommended that I put in a rubber pan liner between the layers of mortar like you do with a tiled shower. I trying to balance the risk of leaks through the tile vs. the floor's stability. Since the drain is just for emergencies and won't be used regularly (hopefuly not at all) I'm wondering if it's a good idea. My concern is how well the tiled floor will last with the vibrations from the washer and dryer it it's got the rubber sheet layer. How well does the mortar bond to this rubber?
Any opinions?
