The good news is that the counter tile was set on a cement slab. That means we can clean that slab and reuse it, obviating our plans to cut a new cement board base. Enrico and Reuben pulled the sinks and finished the slab, while Stan ran to Home Depot for an attachment to Enrico's brand new hammer drill. The new chisel is locked and loaded, below, as Enrico takes his final slices at the shower base.
