My kitchen and laundry room are very much connected. I am putting an oak wood floor in the kitchen to match the rest of my 1950 house. It will continue into the laundry area. The floor contractor suggests a sloped tile floor with drain just under the washer/dryer.

Any suggestions or concerns regarding these plans? Can you put a washer on a sloped tile floor and still balance it? Would it be so bad to just put the washer on the wood floor? I would appreciate any thoughts. Thank you.
