In selecting a 10-inch-depth single bowl sink to replace a 9-inch-depth double bowl, I want to make things as easy as possible for the installing plumber and subsequent plumbers. My concern is that a center drain with waste disposer will make it very tough to get to the copper plumbing and supply lines. Should I select a right or left drain sink to make installation or future repairs easier? Also: Any opinions on brands or 16 vs 18 gauge for the sink or faucet brand recommendations? I'm looking at the fast connect Glacier Bay pull-down sprayer line for the faucet and a Ruvati sink.Thanks in advance.
