Because this happened last week:
I decided to redo the entire thing, and ended up with this:
Long story short, the sink was full of water and for whatever reason the epoxy holding it up to the underside of the counter let go. The new sink now has some wood bracing to give it extra strength so it shouldn't be an issue again. Not pictured is the badass of all garbage disposals than can supposedly chew through bone while remaining quiet and vibration-free! The sink is a heavy-gauge SS304 with insulation and sound dampening on the underside of it for a nice solid sound and feel vs. the thin and tinny of the old one.
