Tackling an outdoor kitchen project this summer or fall? If your outdoor kitchen design includes a working sink, there’s going to be some plumbing involved. Before you get started, make sure you know what you’re getting into. Here’s what you need to know about outdoor kitchen plumbing.
Outdoor Kitchen Plumbing: The Basics
Building an outdoor kitchen is a big undertaking. DIY plumbing is not recommended. Beware that special skills and knowledge are needed to prevent plumbing disasters like leaks, freezing, and burst pipes. Whether you decide to hire a professional or do the work yourself, here are the basic steps:
- Add a water supply line from inside the house, with shutoff valves and drain plugs at the lowest point.
- Run the supply line through the wall of the house and out to the outdoor kitchen.
- Route the pipe through the bottom of the outdoor sink base cabinet.
- Install male-threaded adapters for the sink tubes.
- Install a PVC drainpipe and a sink trap adapter.
- Connect the sink and the trap.
- Dig a hole for a dry well at least 10 feet away.
- Dig a trench out to the dry well, sloping down and away from the house.
- Run a PVC drain line through the trench.
- Install the dry well, connecting the drain line through a hole in the side.

Can You Build an Outdoor Kitchen Without a Sink?
You don’t have to include a working sink in your plans. However, there are some key advantages to adding a sink with running water. An outdoor kitchen sink keeps you from running back into the house every time you need water for food prep, cooking, and cleanup. So it makes outdoor cooking and entertaining way more convenient.
