We live in a ranch home built in 1965 and the laundry area is in a 6'3" x 4'11" alcove area off the kitchen. The problem we encountered is when our washer overflowed over the top of the washer and continued running, ruining our newly installed vinyl floor and sub-floor.
To prevent this from occurring again, we thought that we would install a floor drain with ceramic tiles to butt up to the vinyl flooring in the rest of the kitchen. Currently, the stationary sink drain enters/exits through the wall and is 1-1/2", plastic to copper. The laundry area has always been on the first floor since the basement is lower than the septic system and would have to pump water uphill to eliminate it.
My question is how to pitch this this floor and what materials to use to get the best slope it to the drain, using 12" square ceramic as the top covering?
Included are pictures of the area and the sink.
Thanks so much for any advice!
