Our washer drains into a laundry tub. Unfortunately if someone leaves crap in the tub it overflows. This has happened about four times now, flooding out the basement washroom below.
I'd like to install a drain under the washer, dryer and laundry tub. My idea is to raise the rest of the room with some marine grade plywood, leaving the washer, dryer and tub lower than the rest of the room. I'd then install some linoleum and seal up the edges with silcone caulk. But this still leaves the possibility of water seeping out the edges. So what can I use to form my own pan about an inch up the walls? How about some EPDM under the Linoleum? I know I could tile, but this requires more skill and I'm concerned about water leaking through the grout?
I'll also be investing in a Laundry Tub with an overflow drain.
