A dedicated potting bench changes how you work in the garden. Instead of crouching on the ground or commandeering the kitchen counter, you have a standing-height workspace with storage beneath and hooks above. You can pot seedlings, mix soil, sort tools, and repot containers without searching for a surface that can handle the mess.
This build is designed for a beginning woodworker with access to basic tools: a circular saw or miter saw, a drill, and sandpaper. The design is straightforward — no complicated joinery, no special jigs — but the result is a sturdy, useful piece that will last many years in western red cedar. For material comparisons and what to look for when buying cedar, see our materials and buying guides. And if you want a pre-built option, our potting station collection has several ready-made configurations.
Materials and Cut List
This design uses 2x6 and 1x6 western red cedar throughout. Dimensions are for a bench 60 inches wide, 24 inches deep, and 36 inches tall — a comfortable standing work height for most adults.

Step-by-Step Build
Step 1: Build the Two Side Frames
Each side frame consists of two legs joined by an upper and lower stretcher. The upper stretcher sits 35.25 inches from the bottom of the legs (flush with the top). The lower stretcher sits 12 inches from the ground — this sets the shelf height. Drill pilot holes and drive two 3-inch screws through the stretcher into each leg end. Clamp before drilling to hold position while you work. Repeat for the second side frame.
Step 2: Connect the Two Frames
Stand the two side frames parallel, spacing them 57 inches apart (outside to outside). The front and back 2x6 stretchers connect the frames at the top on front and back. These carry the weight of the work surface, so use two 3-inch screws at each connection. Check for square by measuring the diagonals — they should be equal.
Step 3: Install the Work Surface
Lay five 1x6 boards across the top frame, evenly spaced with about a quarter-inch gap between boards for drainage. Let the boards run flush with or slightly proud of the front edge, and flush at the back. Drill pilot holes and fasten each board with two 1.5-inch screws at each stretcher crossing. The gaps allow water, soil, and debris to fall through rather than pooling on the surface.
Step 4: Install the Bottom Shelf
Lay four 1x6 boards across the lower stretchers. Leave small gaps between boards as with the work surface. Fasten with 1.5-inch screws. This shelf holds bags of potting mix, pots, and garden supplies within easy reach.
Step 5: Add the Peg Rail
Attach the 1x4 rail horizontally across the back of the bench, positioned about 6 inches above the work surface. Install cup hooks or drive wooden dowel pegs every 6 to 8 inches. This holds hand tools — trowels, dibbers, pruners — at working height.
Finishing
Cedar weathers to a natural silver-grey without any treatment, which looks appropriate in most garden settings. If you want to preserve the warm natural color longer, apply a coat of tung oil or exterior-grade linseed oil. Avoid interior finishes, which will peel outdoors. The work surface will accumulate soil stains over time regardless of finish — this is normal and adds character rather than compromising the wood.
Frequently Asked Questions
How long will a cedar potting bench last outdoors?
Western red cedar in outdoor conditions typically lasts 15 to 20 years without rot if it is not in constant contact with wet soil. The bench feet are the most vulnerable point. Keeping the bench on pavers rather than directly on damp ground extends the life considerably.
Do I need special tools to build this?
A circular saw or miter saw, a drill/driver, a speed square, clamps, and sandpaper cover everything this build requires. No joinery tools, no router, no table saw needed.
Can I adjust the dimensions?
Yes. The width can be adjusted by changing the length of the stretchers and surface boards. The height can be adjusted by changing the leg length. A common variation for tall gardeners is 38 to 40 inches; for wheelchair users, 28 to 30 inches with appropriate knee clearance below. See our accessible gardening guides for ADA-compliant dimensions.
What screws should I use for an outdoor cedar bench?
Exterior-rated screws — either stainless steel or coated (ACQ-rated) — prevent the rust staining that regular zinc-plated screws cause in cedar. The tannic acid in cedar reacts with standard steel screws and leaves dark streaks on the wood surface within a season.
Should I add a roof or cover to protect the bench?
Cedar handles rain well, but a covered location extends the life of any outdoor wood furniture. If you are locating the bench in an exposed spot, a simple tarp or canvas cover during the off-season is worth the minor inconvenience.
