Good job with the garbage bags taped around for protection from water.
Agree, this is an installation.
Once my husband was pulling the broken disposal unit out and there was water in it. Which he dumped in the sink! The water of course poured through the open drain. He grabbed a bowl and caught some water and dumped it right back it in the sink again! We laughed so hard we cried.
But it would have been easier to clean if there had been some garbage bags lining the cupboard.
