An outdoor sink in a Broken Arrow masonry outdoor kitchen — connected to the home’s cold water supply (and optionally hot water, though hot water supply to an outdoor kitchen is rarely justified by the added plumbing cost) — eliminates the most common disruption to outdoor entertaining: trips from the outdoor kitchen into the house to wash hands, rinse produce, fill large pots, or empty drip trays. A properly plumbed outdoor sink with adequate drain line to the home’s sewer system makes the outdoor kitchen genuinely self-contained for cooking and cleanup, reducing indoor kitchen traffic during outdoor entertaining events. VistaScapes & Design includes outdoor sink rough-in coordination as a standard part of every Broken Arrow outdoor kitchen project where the homeowner wants sink capability.
Bar Sink vs Full Prep Sink
Outdoor kitchen sinks are available in two primary configurations: a bar sink (a small single-basin sink, typically 9 inches by 9 inches or 15 inches by 15 inches, designed for glass rinsing, hand washing, and light food rinsing in a bar counter section) and a full prep sink (a larger single or double-basin sink, typically 18 to 24 inches wide, designed for washing produce, filling large cooking vessels, and more demanding food prep tasks in the kitchen’s cooking section). For outdoor kitchens with a dedicated bar section, a bar sink in the bar counter and a prep sink in the cooking run serve different functions simultaneously — the bar sink handles drink service and glass rinsing without walking to the cooking side, and the prep sink handles cooking prep without walking to the bar. When the kitchen layout only has space for one sink location, a 15-inch square single-basin sink positioned at the end of the cooking run (between the prep zone and the bar section) is the best compromise between cooking utility and bar service function.
Drain and Supply Line Planning
The outdoor sink’s supply line — a cold water line from the home’s interior supply to the outdoor kitchen base — must be insulated and equipped with an interior shutoff valve that is accessible from inside the garage or laundry room for winterization. The drain line from the outdoor sink runs from the sink drain to a connection on the home’s main drain line or sewer lateral — outdoor kitchen sinks in Oklahoma must drain to the home’s sewer or to an approved dry well per Broken Arrow’s plumbing code. The drain line must maintain adequate slope (1/4 inch per foot minimum) from the outdoor sink drain to the connection point, which may require routing the drain below the concrete slab through a trench — this work is coordinated with the licensed plumber and is easier to complete during the outdoor kitchen’s original construction than as a later addition. We specify the supply and drain line routing in the written proposal for every Broken Arrow outdoor kitchen project that includes a sink.
