Deep sinks are very handy but they take up more room underneath and may require a lowering the drain height to make them fit. Before you buy a kitchen sink
it is a good idea to check the height of the trap arm from the floor or base of cabinet. Measure to the center of the trap arm. If the height is more than 16” you may have a difficult time getting the necessary grade, particularly if a garbage disposer is also being installed. Knowing the height of the existing drain ahead of time will help ensure that you are prepared and have enough time to lower the drain during the installation.
