Once the sink and faucet is lifted out, it will pretty much look like this. Just a big hole and none too pretty. Don't worry, now is the time to ready the new sink for installation.
Make sure to clean the edges of the old sink opening of all old plumbers putty or caulk. Carefully scrape the residual putty or caulk with a putty knife if necessary. Clean the area with a household surface cleaner.
