Product review (4 stars): Something you don't think you need till you need it...
The plastic is thick enough to do the job. Although I did eventually break the edge while moving the washing machine to get under it for repairs, it stands up to some abuse. I was able to easily repair the break it with a glue gun. I would buy it again. People with washing machines or water heaters not on the ground floor, best install the drain fixture that's included.
