Have a kitchen faucet to replace. Sink has a bar above it with stools opposite. Made me think in the old days the bath fixtures usually had access from the closet on the other side through a little door or panel.
Never seen a kitchen cabinet in a bar use the same idea. A panel that would remove to service the kitchen faucet, hose etc. Laying on ones back under a sink trying to reach up between the wall and the sink to the faucet bottom is a real pain. Be a lot easier with a panel.
My rant against cabinet makers for the day.
Good amount of work on your installations.
