You can repair instead of replacing. Install a brace and glue the crack and remove screws and brace once glue sets up. Use wood filler, then stain or paint to cover up.
I concord with Bruce, don't need a plumber to replace the vanity and the plumbing it's vary basic, who ever installed it might do it him or herself...
I concur with Bruce, but , Home Depot has installation people who can install a new vanity at competitive prices
No, If you are talking about the toilet. But if you may need new toilet coz replacement tank mightb
If the cabinet has a sink you will need to disconnect water lines and transfer sink to new cabinet. For that you will need someone who knows plumbing. Most likely the person putting in new cabinet would know how to do that.
